Highlights of GAO-11-38, a report to congressional requesters. 

Why GAO Did This Study: 

Over the last 5 years, Border Patrol has nearly doubled the number of 
its agents on patrol, constructed hundreds of miles of border fence, 
and installed surveillance equipment on and near lands managed by the 
Departments of the Interior and Agriculture along the southwestern 
border. In so doing, the agency has had to comply with federal land 
management laws, and some have expressed concern that these laws may 
limit agents’ abilities to detect and apprehend undocumented aliens. 
GAO was asked to examine (1) key land management laws Border Patrol 
operates under and how it and land management agencies coordinate 
their responsibilities under these laws; (2) how Border Patrol 
operations are affected by these laws; and (3) the extent to which 
land management agencies collect and use data related to the 
environmental effects of illegal activities, such as human trafficking 
and drug smuggling. GAO reviewed key land management laws, interviewed 
agents-in-charge at 26 Border Patrol stations responsible for 
patrolling federal southwest borderlands, and interviewed managers of 
these lands. 

What GAO Found: 

When operating on federal lands, Border Patrol has responsibilities 
under several federal land management laws, including the National 
Environmental Policy Act, National Historic Preservation Act, 
Wilderness Act, and Endangered Species Act. Border Patrol must obtain 
permission or a permit from federal land management agencies before 
its agents can maintain roads and install surveillance equipment on 
these lands. Because land management agencies are also responsible for 
ensuring compliance with land management laws, Border Patrol generally 
coordinates its responsibilities under these laws with land management 
agencies through national and local interagency agreements. The most 
comprehensive agreement is a 2006 memorandum of understanding intended 
to guide Border Patrol activities on federal lands. 

Border Patrol’s access to portions of some federal lands along the 
southwestern border has been limited because of certain land 
management laws, according to patrol agents-in-charge for 17 of the 26 
stations, resulting in delays and restrictions in agents’ patrolling 
and monitoring these lands. Specifically, patrol agents-in-charge for 
14 of the 17 stations reported that they have been unable to obtain a 
permit or permission to access certain areas in a timely manner 
because of how long it takes for land managers to conduct required 
environmental and historic property assessments. The 2006 memorandum 
of understanding directs the agencies to cooperate with one another to 
complete, in an expedited manner, all compliance required by 
applicable federal laws, but such cooperation has not always occurred. 
For example, Border Patrol requested permission to move surveillance 
equipment to an area, but by the time the land manager conducted a 
historic property assessment and granted permission—more than 4 months 
after the initial request—illegal traffic had shifted to other areas. 
Despite the access delays and restrictions, 22 of the 26 agents-in-
charge reported that the overall security status of their jurisdiction 
is not affected by land management laws. Instead, factors such as the 
remoteness and ruggedness of the terrain have the greatest effect on 
their ability to achieve operational control. Although 4 agents-in-
charge reported that delays and restrictions have affected their 
ability to achieve or maintain operational control, they either have 
not requested resources for increased or timelier access or have had 
their requests denied by senior Border Patrol officials, who said that 
other needs were more important. 

While federal land managers in the borderlands region rely on Border 
Patrol to collect data on the extent of cross-border illegal 
activities on their lands, the extent of the land managers’ data 
collection efforts on the effects of these illegal activities has 
varied. Some land managers monitor areas on a routine basis, some 
document environmental damage on an ad hoc basis, and still others 
collect no such data. Where collected, land managers have used these 
data for several purposes, including restoring lands and providing 
Border Patrol agents with environmental awareness training. With 
regard to training, most agents-in-charge wanted more-frequent, area-
specific training to be provided by land managers. 

What GAO Recommends: 

GAO recommends, among other things, that the Secretaries of Homeland 
Security, the Interior, and Agriculture take steps to help Border 
Patrol expedite access to portions of federal lands by more quickly 
initiating required assessments. In commenting on a draft of this 
report, the agencies generally agreed with GAO’s findings and 
recommendations.

Congressional Requesters: 

Enhancing the security of the nation's border with Mexico has emerged 
as a significant policy issue, particularly on federal lands, where 
illegal cross-border activity threatens not only people but also 
natural resources. In the mid-1990s, the U.S. Border Patrol--an office 
within the Department of Homeland Security's (DHS) Customs and Border 
Protection division that is responsible for detecting and preventing 
the entry of terrorists, weapons of mass destruction, and undocumented 
aliens--increased its personnel and resources in large urban areas 
along the United States-Mexico border to curtail illegal human and 
narcotics trafficking. With this strategy, Border Patrol successfully 
reduced illegal border crossings in places like San Diego, California, 
and El Paso, Texas. Border Patrol's strategy puts a high priority on 
border enforcement in urban and populated areas, which can divert 
large concentrations of illegal traffic to federal lands and other 
remote areas where vast landscapes and often rugged terrain may take 
days to cross--giving agents more time to detect undocumented aliens 
and make apprehensions. 

The remoteness and harsh conditions found across much of the 
southwestern border, however, have not deterred illegal traffic as 
much as expected. Instead, it has increased substantially since the 
mid-1990s on federal lands managed by the Departments of the Interior 
and Agriculture, whose borderlands encompass over 40 percent of the 
1,900 miles of southwestern border in Arizona, California, New Mexico, 
and Texas. Evidence has since shown that this traffic has damaged 
natural and cultural resources on federal lands. Specifically, federal 
land managers have documented thousands of miles of immigrant trails 
and thousands of pounds of trash--littering landscapes that have more 
wildlife and plant species listed under the Endangered Species Act 
than any other geographic region in the continental United States. As 
an unintended consequence, Border Patrol's efforts to curtail illegal 
traffic have also degraded natural and cultural resources on these 
lands that were set aside for protection by past Congresses and 
administrations. 

In response to the increase in illegal traffic on federal lands along 
the southwestern border, over the last 5 years, Border Patrol has 
nearly doubled the number of its agents on patrol, constructed 
hundreds of miles of pedestrian fences and vehicle barriers, and 
installed surveillance equipment on and near federal lands managed by 
the Bureau of Land Management, Fish and Wildlife Service, and National 
Park Service within Interior, and the Forest Service within 
Agriculture. As a result of Border Patrol's increased presence on 
these borderlands, some land managers have asserted that their 
abilities to carry out their natural resource protection 
responsibilities, such as limiting vehicle traffic in environmentally 
sensitive areas, are sometimes affected by the methods that Border 
Patrol agents use to carry out their homeland security 
responsibilities--such as patrolling and installing surveillance 
equipment in remote areas. While both Border Patrol and land 
management agency officials have acknowledged that fulfilling their 
respective responsibilities can work at cross-purposes, these 
officials also recognize that Border Patrol's presence can help 
protect natural and cultural resources on federal lands by deterring 
undocumented aliens. Border Patrol and land management agency 
officials have stated that interagency coordination is therefore 
needed in the southwestern borderlands region.[Footnote 1] 

In this context, you asked us for information on Border Patrol's 
operations on federal lands managed by Interior and the Forest Service 
along the nation's southwestern border. Accordingly, this report (1) 
describes the key land management laws Border Patrol operates under 
and how it and land management agencies coordinate their 
responsibilities under these laws, (2) examines how Border Patrol 
operations are affected by these laws, and (3) identifies the extent 
to which land management agencies collect data related to cross-border 
illegal activities and associated environmental impacts and how these 
data are used. 

To respond to these objectives, we examined agency documents 
describing the laws that apply to Border Patrol operations on federal 
lands along the southwestern border, reviewed these key land 
management laws, and examined documents describing how Border Patrol 
and land management agencies are to coordinate their responsibilities 
under these laws. We visited selected federal land units and Border 
Patrol stations responsible for patrolling these units in Arizona, 
California, and Texas. We selected these units, and the stations 
responsible for patrolling them, on the basis of geographical 
diversity, the extent of and impact from cross-border illegal 
activity, and the type of land management agency. Further, we 
conducted telephone interviews with land managers for federal land 
units along the border that we did not visit, including those in New 
Mexico. Although the information we obtained is not generalizable to 
all land units in the borderlands region, it represents the full 
spectrum of information available on the extent of and impact from 
cross-border illegal activity. We also developed and used a structured 
interview to obtain the views of patrol agents-in-charge, or their 
designees, of the 26 stations in the borderlands region that have 
federal lands within their jurisdictions on whether and to what extent 
their operations are affected by land management laws (see figure 1).

From Border Patrol, we obtained data on enforcement actions on illegal 
activities that occurred from 2004 to 2009 on federal lands along the 
southwestern border. From land managers, we obtained data on the 
environmental effects of these illegal activities, as well as data on 
the environmental effects of Border Patrol's related response to such 
activities. We further obtained and analyzed environmental data used 
by DHS as the basis for the department's commitment to fund mitigation 
efforts for environmental damage caused by three border fencing 
projects. Additionally, we obtained a project list that land managers 
provided to DHS for developing the mitigation needs on their lands. 
Appendix I describes our scope and methodology in more detail. 

We conducted this performance audit from December 2009 to October 
2010, in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives. 

Background: 

The southwestern borderlands region contains many federally managed 
lands and also accounts for over 97 percent of all apprehensions of 
undocumented aliens by Border Patrol. Over 40 percent of the United 
States-Mexico border, or 820 linear miles, is managed by Interior's 
land management agencies and the Forest Service. Each of these land 
management agencies has a distinct mission and set of responsibilities: 

* The Bureau of Land Management manages federal land for multiple 
uses, including recreation; range; timber; minerals; watershed; 
wildlife and fish; natural scenic, scientific, and historical values; 
and the sustained yield of renewable resources. 

* The Park Service conserves the scenery, natural and historical 
objects, and wildlife of the national park system so they will remain 
unimpaired for the enjoyment of this and future generations. 

* The Fish and Wildlife Service preserves and enhances fish, wildlife, 
plants, and their habitats, primarily in national wildlife refuges. 

* The Forest Service manages lands for multiple uses, such as timber, 
recreation, and watershed management and to sustain the health, 
diversity, and productivity of the nation's forests and grasslands to 
meet the needs of present and future generations. 

Border Patrol's mission is defined by the Immigration and Nationality 
Act, as amended, which gives the Secretary of Homeland Security the 
power and duty to control and guard the boundaries and borders of the 
United States against the illegal entry of people who are not citizens 
or nationals.[Footnote 3] To fulfill this mission, Border Patrol 
agents patrol federal and nonfederal lands near the border to find and 
apprehend persons who have illegally crossed the U.S. border. Agents 
carry out this mission primarily between ports of entry, located in 
cities such as El Paso, Texas, and San Ysidro, California, and have 
the authority to search, interrogate, and arrest undocumented aliens 
and others who are engaging in illegal activities, such as illegal 
entry and smuggling of people, drugs, or other contraband. Border 
Patrol is organized into nine sectors along the southwestern border. 
Within each sector, there are stations with responsibility for defined 
geographic areas. Of the 41 stations in the borderlands region in the 
9 southwestern border sectors, 26 have primary responsibility for the 
security of federal lands in the borderlands region, according to 
Border Patrol sector officials.[Footnote 4] 

Apprehensions of undocumented aliens along the southwestern border 
increased steadily through the late 1990s, reaching a peak of 
1,650,000 in fiscal year 2000. Since fiscal year 2006, apprehensions 
have declined, reaching a low of 540,000 in fiscal year 2009. This 
decrease has occurred along the entire border, with every sector 
reporting fewer apprehensions in fiscal year 2009 than in fiscal year 
2006. The Tucson Sector, however, with responsibility for central and 
eastern Arizona, continues to have the largest number of apprehensions 
(see figure 2).[Footnote 5] Border Patrol shares with land managers 
data on apprehensions and drug seizures occurring on federal land, 
providing such information in several ways, including in regularly 
occurring meetings and e-mailed reports.

Border Patrol measures its effectiveness at detecting and apprehending 
undocumented aliens by assessing the border security status for a 
given area. The two highest border security statuses--"controlled" and 
"managed"--are levels at which Border Patrol claims the capability to 
consistently detect entries when they occur; identify what the entry 
is and classify its level of threat (such as who is entering, what the 
entrants are doing, and how many entrants there are); effectively and 
efficiently respond to the entry; and bring the situation to an 
appropriate law enforcement resolution, such as an arrest. Areas 
deemed either "controlled" or "managed" are considered by Border 
Patrol to be under "operational control."[Footnote 6] 

Patrol agents-in-charge of Border Patrol stations aim to achieve 
operational control of their jurisdictions by deploying a mix of 
personnel, technology, and tactical infrastructure, such as vehicle 
and pedestrian fences, in urban and rural areas along the border. 
These activities are part of DHS's Secure Border Initiative--a 
multiyear, multibillion dollar program aimed at securing U.S. borders 
and reducing illegal immigration.[Footnote 7] Since the program began 
in 2005, Border Patrol has nearly doubled the number of agents along 
the northern and southern U.S. borders to 20,200, with more than 
17,000 agents (85 percent) on the southwestern border. According to 
Tucson Sector Border Patrol officials, having more agents has allowed 
the agency to patrol additional areas, such as remote federal lands. 
As part of routine operations to detect undocumented aliens, agents in 
remote areas typically travel on roads near the border--generally 
those that parallel the border east to west--several times a day in 
search of signs of illegal traffic, such as footprints. 

In addition to the increase in the number of agents along the 
southwestern border over the last 5 years, DHS has spent about $1.6 
billion to provide technological resources in the borderlands region 
as part of the Secure Border Initiative.[Footnote 8] These resources 
include surveillance technologies, such as underground sensors, 
cameras, and radar, among other things. For example, to assist agents 
in detecting illegal entries, Border Patrol uses mobile surveillance 
systems (see figure 3). These systems are mounted on trucks outfitted 
with towers that have infrared cameras and live video feeds for 
detecting suspected undocumented aliens. According to Border Patrol 
field agents, once an entry is detected, agents monitoring a system 
can direct other agents to respond and apprehend the suspected 
undocumented aliens. As illegal traffic shifts within a station's area 
of operation--such shifts can occur daily--agents can move the mobile 
surveillance systems as needed. 

Figure 3: A Border Patrol Mobile Surveillance System:

[End of figure] 

In addition to increasing the number of agents and technological 
resources along the border, DHS has installed hundreds of miles of 
tactical infrastructure as part of the Secure Border Initiative. 
Specifically, as of April 2010, the department had completed 646 of 
the 652 miles of border fencing it committed to deploy along the 
southwestern border, including pedestrian fencing and permanent 
vehicle barriers (see figure 4). According to a Tucson Sector Border 
Patrol official, pedestrian fencing is typically located near urban 
areas and is designed to prevent people on foot from crossing the 
border. Vehicle barriers consist of physical barriers meant to stop 
the entry of vehicles; almost all the fencing on federal lands along 
the southwestern border consists of vehicle barriers.

Note: The picket, bollard, and post-and-rail fences are examples of 
pedestrian fencing. The Normandy-style fence is an example of a 
vehicle fence. 

[End of figure] 

Border Patrol's strategy emphasizes border enforcement in urban and 
populated areas, which can divert large concentrations of illegal 
traffic to outlying areas--including federal lands--where Border 
Patrol believes its agents have more time to detect and apprehend 
undocumented aliens attempting to cross vast and remote landscapes. A 
consequence of this strategy, however, is an impact on natural, 
historic, and cultural resources on federal lands--resources that land 
management agencies are charged with conserving, preserving, and 
protecting. According to a 2003 Interior report, endangered species 
and their habitats are potentially being irreversibly damaged from 
this illegal activity.[Footnote 9] 

In addition to damage caused by undocumented aliens traversing 
environmentally sensitive lands, Border Patrol's deployment of 
personnel, technology, and infrastructure resources on federal lands 
can also have negative impacts on certain plants and wildlife that are 
protected under federal law. For example, according to a Fish and 
Wildlife Service refuge manager in the borderlands region, when Border 
Patrol agents use vehicles off road to patrol or pursue suspects on 
federal lands, the tire tracks left by their vehicles may remain for 
years (see figure 5). The tracks from these off-road incursions can 
disrupt water flow from slopes and mountain ranges. This runoff 
normally pools and provides water for vegetation, which allows 
wildlife to survive through hot, dry summers. With tire tracks, the 
water collects in the tracks instead of natural pools. As a result, 
pools are smaller and evaporate more quickly, leading to less 
vegetation, less available food, and fewer animals able to survive the 
summer.

[End of figure] 

The number of undocumented aliens crossing federal lands along the 
southwestern border can overwhelm law enforcement and resource 
protection efforts by federal land managers, thus highlighting the 
need for Border Patrol's presence on and near these lands, according 
to DHS and land management agency officials. The need for the presence 
of both kinds of agencies on these borderlands has prompted 
consultation among DHS, Interior, and Agriculture to facilitate 
coordination between Border Patrol and the land management agencies. 
The departments have a stated commitment to foster better 
communication and resolve issues and concerns linked to federal land 
use or resource management. 

Border Patrol Operates under Several Land Management Laws and 
Coordinates Its Responsibilities under These Laws with Land Management 
Agencies through National and Local Agreements: 

When operating on federal lands, Border Patrol has responsibilities 
under several federal land management laws, including the National 
Environmental Policy Act of 1969, Wilderness Act of 1964, and 
Endangered Species Act of 1973, and it generally coordinates its 
responsibilities under these laws with land management agencies 
through national and local interagency agreements. Border Patrol must 
obtain permission or a permit from federal land management agencies 
before its agents can undertake certain activities on federal lands, 
such as maintaining roads and installing surveillance equipment. 
Because the land management agencies are responsible for ensuring 
compliance with land management laws, Border Patrol and the land 
management agencies have developed several mechanisms to coordinate 
their responsibilities. The most comprehensive of these is a national-
level agreement--a memorandum of understanding signed in 2006 by the 
Secretaries of Homeland Security, the Interior, and Agriculture--
intended to provide consistent principles to guide their agencies' 
activities on federal lands. At the local level, Border Patrol and 
land management agencies have also coordinated their responsibilities 
through various local agreements. 

Several Land Management Laws Govern Border Patrol Operations on 
Federal Lands: 

Border Patrol, like all federal agencies, must obtain permission or a 
permit from the appropriate federal land management agency to conduct 
certain activities--such as road maintenance--on federal lands. 
[Footnote 10] To obtain permission or a permit, Border Patrol and land 
management agencies must fulfill the requirements of various land 
management laws, including, but not limited to, the following: 

* National Environmental Policy Act of 1969.[Footnote 11] Enacted in 
1970, the National Environmental Policy Act's purpose is to promote 
efforts that will prevent or eliminate damage to the environment, 
among other things. Section 102 requires federal agencies to evaluate 
the likely environmental effects of proposed projects using an 
environmental assessment or, if the projects would likely 
significantly affect the environment, a more detailed environmental 
impact statement evaluating the proposed project and alternatives. 
Environmental impact statements can be developed at either a 
programmatic level--where larger-scale, combined effects and 
cumulative effects can be evaluated and where overall management 
objectives, such as road access and use, are defined--or a project 
level, where the effects of a particular project in a specific place 
at a particular time are evaluated. If, however, the federal agency 
determines that activities of a proposed project fall within a 
category of activities the agency has already determined has no 
significant environmental effect--called a categorical exclusion--then 
the agency generally does not need to prepare an environmental 
assessment or an environmental impact statement. The agency may 
instead approve projects that fit within the relevant category by 
using one of the predetermined categorical exclusions, rather than 
preparing a project-specific environmental assessment or environmental 
impact statement.[Footnote 12] 

When more than two federal agencies are involved in an activity--as is 
the case with Border Patrol operations on federal lands--National 
Environmental Policy Act regulations require that a lead agency 
supervise the preparation of the environmental impact statement. Under 
a 2008 memorandum of agreement between Border Patrol and Interior's 
land management agencies, Border Patrol is to be the lead agency on 
preparation of National Environmental Policy Act documents for all 
Border Patrol tactical infrastructure projects. For all other 
projects, such as road maintenance, Border Patrol or Interior land 
management agencies may be the lead, joint lead, or a cooperating 
agency. When Border Patrol and Interior land management agencies are 
joint lead agencies, they share responsibility for developing the 
scope and content of the environmental assessments and environmental 
impact statements. When either agency is a cooperating agency, it can 
develop its own environmental assessment or environmental impact 
statement or adopt the one developed by the lead agency if the 
cooperating agency reviews it and finds that its comments and 
suggestions have been satisfied.[Footnote 13] 

Once the lead and cooperating agencies agree on a draft environmental 
impact statement, a notice of its availability is published in the 
Federal Register and it is made available for public notice and 
comment for at least 45 days. The agencies are to then prepare a final 
environmental impact statement and publish a notice of its 
availability in the Federal Register. At least 30 days after the 
notice of availability for the final environmental impact statement is 
published, the lead agency must publish a record of its decision, 
describing how the findings of the environmental impact statement were 
incorporated into the agency's decision-making process. Figure 6 
illustrates the process for implementing National Environmental Policy 
Act requirements.

* National Historic Preservation Act of 1966.[Footnote 14] The 
National Historic Preservation Act provides for the protection of 
historic properties--any prehistoric or historic district, site, 
building, structure, object, or properties of traditional religious 
and cultural importance to an Indian tribe, included, or eligible for 
inclusion in, the National Register of Historic Places. For all 
projects receiving federal funds or a federal permit, section 106 of 
the act requires federal agencies to take into account a project's 
effect on any historic property. In accordance with regulations 
implementing the act, Border Patrol and land management agencies often 
incorporate compliance with the National Historic Preservation Act 
into their required evaluations of a project's likely environmental 
effects under the National Environmental Policy Act. Thus, the lead 
agency or agencies on Border Patrol's proposed projects or activities 
on federal lands must determine, by consulting with relevant federal, 
state, and tribal officials, whether a project or activity has the 
potential to affect historic properties. The purpose of the 
consultation is to identify historic properties affected by the 
project; assess the activity's adverse effects on the historic 
properties; and seek ways to avoid, minimize, or mitigate any of those 
effects. Specifically, the consultation is to determine and document a 
proposed action's area of potential effects; assess whether the 
proposed project would alter, directly or indirectly, certain 
characteristics of the historic property; and develop and evaluate 
alternatives or modifications to the proposed project or activity that 
could avoid, minimize, or mitigate adverse effects. The entire 
process, including resolution of any adverse effects, must be 
completed before the relevant land management agency can issue a 
permit or grant permission to proceed with the proposed activity. 

* Wilderness Act of 1964.[Footnote 15] The Wilderness Act of 1964 
provides for federal lands to be designated as "wilderness areas," 
which means that such lands are to be administered in such a manner 
that will leave them unimpaired for future use and enjoyment and to 
provide for their protection and the preservation of their wilderness 
character, among other goals. If Border Patrol proposes to patrol or 
install surveillance equipment on federal land that has been 
designated as wilderness, the agency must comply with the requirements 
and restrictions of the Wilderness Act of 1964, other laws 
establishing a particular wilderness area, and the relevant federal 
land management agency's regulations governing wilderness areas. 
[Footnote 16] Section 4 of the act prohibits the construction of 
temporary roads or structures, as well as the use of motor vehicles, 
motorized equipment, and other forms of mechanical transport in 
wilderness areas, unless such construction or use is necessary to meet 
the minimum requirements for administration of the area, including for 
emergencies involving health and safety. 

Generally, the land management agencies have regulations that address 
the emergency and administrative use of motorized equipment and 
installations in the wilderness areas they manage.[Footnote 17] For 
example, under Fish and Wildlife Service regulations, the agency may 
authorize Border Patrol to use a wilderness area and prescribe 
conditions under which motorized equipment, structures, and 
installations may be used to protect the wilderness, including 
emergencies involving damage to property and violations of laws. 
Forest Service regulations are similar to Fish and Wildlife Service 
regulations but allow the agency to prescribe conditions to protect 
the wilderness and its resources. including in emergencies involving 
damage to property. Under Bureau of Land Management regulations, the 
agency may authorize Border Patrol to occupy and use wilderness areas 
to carry out the purposes of federal laws as well as prescribe 
conditions for Border Patrol's use to protect the wilderness area, its 
resources, and users. 

* Endangered Species Act of 1973.[Footnote 18] The purpose of the 
Endangered Species Act is to conserve threatened and endangered 
species and the ecosystems upon which they depend. Under section 7 of 
the act, if Border Patrol or the land management agencies determine 
that an activity Border Patrol intends to authorize, fund, or carry 
out may affect an animal or plant species listed as threatened or 
endangered, the agency may initiate either an informal or a formal 
consultation with the Fish and Wildlife Service--which we refer to as 
a section 7 consultation--to ensure that its actions do not jeopardize 
the continued existence of such species or result in the destruction 
or adverse modification of its critical habitat. The agencies are to 
initiate informal consultation if they determine that an activity may 
affect--but is not likely to adversely affect--a listed species or 
critical habitat. If the Fish and Wildlife Service agrees, typically 
by issuing a letter of concurrence with Border Patrol or the land 
management agency's determination, then Border Patrol may proceed with 
the activity without further consultation. If Border Patrol or the 
land management agency determines that an activity is likely to 
adversely affect a species, formal consultation must be initiated, 
which involves submitting to the Fish and Wildlife Service a written 
request that includes a description of the proposed action and how it 
may affect threatened or endangered species and their critical 
habitat. The consultation usually ends with the issuance of a 
biological opinion by the Fish and Wildlife Service, and the opinion 
can contain provisions affecting Border Patrol activities.[Footnote 19] 

National and Local Agreements Facilitate Coordination of 
Responsibilities among the Agencies: 

To help implement these key federal land management laws, Border 
Patrol and the land management agencies have developed several 
mechanisms to coordinate their responsibilities, including a national-
level memorandum of understanding and local agreements. The national-
level memorandum of understanding was signed in 2006 by the 
Secretaries of Homeland Security, the Interior, and Agriculture and is 
intended to provide consistent principles to guide the agencies' 
activities on federal lands along the U.S. borders.[Footnote 20] Such 
activities may include placing and installing surveillance equipment, 
such as towers and underground sensors; using roads; providing Border 
Patrol with natural and cultural resource training; mitigating 
environmental impacts; and pursuing suspected undocumented aliens off 
road in wilderness areas. The memorandum also contains several 
provisions for resolving conflicts between Border Patrol and land 
managers, such as directing the agencies to resolve conflicts at and 
delegate resolution authority to the lowest field operations level 
possible and to cooperate with each other to complete--in an expedited 
manner--all compliance that is required by applicable federal laws. 

Some Border Patrol stations and land management agencies have 
coordinated their responsibilities through use of the national-level 
memorandum of understanding. For example, Border Patrol and land 
managers in Arizona used the 2006 memorandum of understanding to set 
the terms for reporting Border Patrol off-road vehicle incursions in 
Organ Pipe Cactus National Monument, as well as for developing 
strategies for interdicting undocumented aliens closer to the border 
in the Cabeza Prieta National Wildlife Refuge and facilitating Border 
Patrol access in the San Bernardino National Wildlife Refuge. Border 
Patrol and land management agencies have also coordinated their 
responsibilities through local agreements that were facilitated by the 
2006 memorandum of understanding, which provides guidance on the 
development of individual local agreements. For example, for the 
Coronado National Forest in Arizona, Border Patrol and the Forest 
Service developed a coordinated strategic plan that sets forth 
conditions for improving and maintaining roads and locating helicopter 
landing zones in wilderness areas, among other issues. Regarding road 
maintenance, the plan states that sufficient funding has not been 
available for the Forest Service to perform road maintenance on many 
of the roads needed by Border Patrol for patrol and surveillance 
operations. It therefore sets forth the conditions for Border Patrol 
to use its own funding to pay for or perform road maintenance on the 
forest.[Footnote 21] Another example of a local agreement that 
resulted from the national-level 2006 memorandum of understanding is 
one between the Bureau of Land Management's Las Cruces office and 
Border Patrol in New Mexico, concerning the maintenance of unpaved 
Bureau of Land Management roads. Specifically, in 2007, the agencies 
agreed in writing that the Bureau of Land Management is to promptly 
review Border Patrol road maintenance requests and expeditiously 
conduct necessary analysis of proposed requests, such as environmental 
and historic property assessments under the National Environmental 
Policy and National Historic Preservation acts. In addition, Border 
Patrol agreed to limit road maintenance so that it does not change the 
existing road profile or include new construction of drainage 
structures. 

Border Patrol and land managers have also used other mechanisms to 
coordinate their responsibilities, such as local agreements predating 
the 2006 memorandum of understanding, as well as a 2000 legal 
settlement requiring a section 7 consultation and an environmental 
impact statement resulting in measures that now govern Border Patrol's 
activities in a certain area. For example, in California, officials in 
the Bureau of Land Management's El Centro office sought input from 
officials in Border Patrol's El Centro Sector in deciding which Bureau 
of Land Management roads to close as part of a comprehensive road 
designation and mapping project. In obtaining Border Patrol's input, 
the Bureau of Land Management decided to keep open numerous roads that 
it had otherwise been planning to close. Border Patrol El Centro 
Sector officials told us they appreciated this local coordination, 
which allowed them the access they needed while helping the Bureau of 
Land Management balance its requirements for protecting resources and 
facilitating vehicle access by Border Patrol and the public. In 
addition, in 2000, Border Patrol settled a lawsuit alleging that its 
Operation Rio Grande in south Texas violated the National 
Environmental Policy Act and the Endangered Species Act. The 
settlement prohibited Border Patrol, on an interim basis, from mowing 
brush in the floodplain of the Rio Grande and clearing, burning, or 
driving through any brush or other vegetation in the floodplain, with 
some exceptions, and using lights at night to illuminate portions of 
the Lower Rio Grande National Wildlife Refuge property, among other 
terms. The legal settlement also required Border Patrol to conduct 
section 7 consultations and prepare an environmental impact statement, 
which resulted in measures that now govern Border Patrol's activities 
in and around the Fish and Wildlife Service's South Texas Refuge 
Complex. 

Several other mechanisms as well have been used to facilitate 
interagency coordination. For example, Border Patrol and Interior 
established interagency liaisons, who have responsibility for 
facilitating coordination among their agencies. Border Patrol's Public 
Lands Liaison Agent program directs each Border Patrol sector to 
designate an agent dedicated to interacting with Interior, 
Agriculture, or other governmental or nongovernmental organizations 
involved in land management issues. The role of these designated 
agents is to foster better communication; increase interagency 
understanding of respective missions, objectives, and priorities; and 
serve as a central point of contact in resolving issues and concerns. 
Key responsibilities of these public lands liaison agents include 
implementing the 2006 memorandum of understanding and subsequent 
related agreements, and monitoring any enforcement operations, issues, 
or activities related to federal land use or resource management. In 
addition, Interior established its own Southwest Border Coordinator, 
located at the Border Patrol Tucson Sector, to coordinate federal land 
management issues among Interior component agencies and with Border 
Patrol. The Forest Service also established a dedicated liaison 
position in the Tucson Sector to coordinate with Border Patrol, 
according to Forest Service officials. In addition to these liaison 
positions, a borderlands management task force provides an 
intergovernmental forum in the field for governmental officials, 
including those from Border Patrol, the land management agencies, and 
other state and local government entities, to regularly meet and 
discuss challenges and opportunities for working together. The task 
force acts as a mechanism to address issues of security, safety, and 
resources among federal, tribal, state, and local governments located 
along the border. 

Land Management Laws Have Limited Border Patrol's Access to Federal 
Lands in Some Areas, but Most Agents-in-Charge Reported No Effect on 
Their Stations' Border Security Status: 

Border Patrol stations' access has been limited on some federal lands 
along the southwestern border because of certain land management laws, 
according to some patrol agents-in-charge in the borderlands region. 
Specifically, 17 of the 26 stations that have primary responsibility 
for patrolling federal lands along the southwestern border reported 
that when they attempt to obtain a permit or permission to access 
portions of federal lands, delays and restrictions have resulted from 
complying with land management laws. Despite these delays and 
restrictions, 22 of the 26 Border Patrol stations reported that the 
border security status of their area of operation has not been 
affected by land management laws. 

More Than Half of Border Patrol Stations Reported That Land Management 
Laws Have Affected Their Access for Patrolling and Monitoring Parts of 
Federal Lands: 

Patrol agents-in-charge of 17 of 26 stations along the southwestern 
border reported that they have experienced delays and restrictions in 
patrolling and monitoring portions of federal lands because of various 
land management laws. Specifically, patrol agents-in-charge of 14 of 
the 17 stations reported that they have been unable to obtain a permit 
or permission to access certain areas in a timely manner because of 
how long it takes for land managers to comply with the National 
Environmental Policy Act and the National Historic Preservation Act. 
In addition, 3 of the 17 stations reported that their agents' ability 
to access portions of federal lands has been affected by Wilderness 
Act restrictions on the creation of additional roads and installation 
of structures, such as SBInet towers. Furthermore, 5 of the 17 
stations reported that as a result of consultations under section 7 of 
the Endangered Species Act, their agents had to change the timing or 
specific location of ground and air patrols because endangered species 
were present in these areas. 

Land Management Agencies' Implementation of the National Environmental 
Policy Act and National Historic Preservation Act Has Caused Delays 
for 14 Stations: 

Fourteen of the 26 Border Patrol stations along the southwestern 
border have reported experiencing delays in getting a permit or 
permission from land managers to gain access to portions of federal 
land because of the time it took land managers to complete the 
requirements of the National Environmental Policy Act and the National 
Historic Preservation Act. These delays in gaining access have 
generally lessened agents' ability to detect undocumented aliens in 
some areas, according to the patrol agents-in-charge. The 2006 
memorandum of understanding directs the agencies to cooperate with 
each other to complete, in an expedited manner, all compliance 
required by applicable federal laws, but such cooperation has not 
always occurred, as shown in the following examples: 

* Federal lands in Arizona. For the Border Patrol station responsible 
for patrolling certain federal lands in Arizona, the patrol agent-in- 
charge reported that it has routinely taken several months to obtain 
permission from land managers to move mobile surveillance systems. The 
agent-in-charge said that before permission can be granted, land 
managers generally must complete environmental and historic property 
assessments--as required by the National Environmental Policy and 
National Historic Preservation acts--on roads and sites needed for 
moving and locating such systems. For example, Border Patrol requested 
permission to move a mobile surveillance system to a certain area, but 
by the time permission was granted--more than 4 months after the 
initial request--illegal traffic had shifted to other areas. As a 
result, Border Patrol was unable to move the surveillance system to 
the locale it desired, and during the 4-month delay, agents were 
limited in their ability to detect undocumented aliens within a 7-mile 
range that could have been covered by the system.[Footnote 22] The 
land manager for the federal land unit said that most of the area and 
routes through it have not had a historic property assessment, so when 
Border Patrol asks for approval to move equipment, such assessments 
must often be performed. Moreover, the federal land management unit 
has limited staff with numerous other duties. For example, the unit 
has few survey specialists who are qualified to perform environmental 
and historic property assessments. Thus, he explained, resources 
cannot always be allocated to meet Border Patrol requests in an 
expedited manner. 

* Federal lands in New Mexico. In southwestern New Mexico, the patrol 
agents-in-charge of four Border Patrol stations reported that it may 
take 6 months or more to obtain permission from land managers to 
maintain and improve roads that Border Patrol needs on federal lands 
to conduct patrols and move surveillance equipment. According to one 
of these agents-in-charge, for Border Patrol to obtain such permission 
from land managers, the land managers must ensure that environmental 
and historic property assessments are completed, which typically 
entails coordinating with three different land management specialists: 
a realty specialist to locate the site, a biologist to determine if 
there are any species concerns, and an archaeologist to determine if 
there are any historic sites. Coordinating schedules among these 
experts often takes a long time, according to a Border Patrol public- 
lands liaison. For example, one patrol agent-in-charge told us that a 
road in his jurisdiction needed to be improved to allow a truck to 
move an underground sensor, but the process for the federal land 
management agency to perform a historic property assessment and issue 
a permit for the road improvements took nearly 8 months. During this 
period, agents could not patrol in vehicles or use surveillance 
equipment to monitor an area that illegal aliens were known to use. 
The patrol agent-in-charge told us that performing such assessments on 
every road that might be used by Border Patrol would take substantial 
time and require assessing hundreds of miles of roads.[Footnote 23] 
According to federal land managers in the area, environmental and 
historic property specialists try to expedite support for Border 
Patrol as much as possible, but these specialists have other work they 
are committed to as well. Moreover, the office has not been provided 
any additional funding to increase personnel to be able to dedicate 
anyone in support of the Border Patrol to expedite such requests. 

* Federal lands in California. For two Border Patrol stations 
responsible for patrolling federal lands in Southern California, the 
patrol agents-in-charge reported that when they request permission for 
road maintenance activities, it can take up to 9 months for permission 
to be granted; occasionally, Border Patrol may not receive permission 
at all. In one case, for example, a patrol agent-in-charge told us 
that better maintenance was needed for five roads and two surveillance 
system sites within her station's area of operation, but because 
permission to maintain these roads was not granted, her agents could 
not conduct routine patrols or reach the sites for mobile surveillance 
systems, even in areas of high illegal traffic (see figure 7). The 
patrol agent-in-charge said that without the permission to maintain 
the poor roads, her agents had to find alternative patrol routes and 
try to apprehend suspected undocumented aliens farther north. In 
addition, because the proposed surveillance sites could not be used, 
agents had to place the mobile surveillance systems in areas less 
prone to illegal traffic. The Bureau of Land Management state program 
manager for this area told us that one bureau employee had, at times, 
told Border Patrol agents that they could not use or have permission 
to maintain a road, whereas the employee should have instructed Border 
Patrol to seek permission from a Bureau of Land Management specialist, 
who could have begun the required environmental and historic property 
assessments. In addition, the state program manager told us that the 
required assessments for road maintenance activities have not been 
completed on many routes. He acknowledged that one of the Bureau of 
Land Management's biggest challenges is being responsive to Border 
Patrol timelines. A Bureau of Land Management field manager for this 
area also told us that the process to approve many Border Patrol 
projects often takes considerable time because the bureau lacks 
sufficient staff resources to expedite Border Patrol requests.

flying at about 200 feet. 

[End of figure] 

For some of the stations, the delays patrol agents-in-charge reported 
could have been shortened if Border Patrol could have used its own 
resources to pay for, or perform, environmental and historic property 
assessments required by the National Environmental Policy Act and 
National Historic Preservation Act, according to patrol agents-in- 
charge and land managers with whom we spoke. On one land unit, Border 
Patrol and land managers have developed such a cooperative arrangement 
and resolved some access delays. Specifically, for the Coronado 
National Forest, agency officials told us that Border Patrol and the 
Forest Service had entered into an agreement whereby in some 
situations Border Patrol pays for road maintenance and the necessary 
environmental and historic property assessments. While two patrol 
agents-in-charge reported that in the past they experienced delays in 
gaining access resulting from poorly maintained roads, they stated 
that the development of the Coronado National Forest coordinated 
strategic plan has helped the agencies shorten the time it takes to 
begin road maintenance because it allows Border Patrol to use its 
resources and therefore begin environmental and historic property 
assessments sooner.[Footnote 24] The plan recognizes that Forest 
Service funding has not been available to adequately maintain the 
forest roads that Border Patrol uses for patrols. Officials from both 
agencies agreed that these roads must be in a drivable condition for 
Border Patrol agents. Agency officials stated that the agencies have 
also agreed to allow Border Patrol to fund additional Forest Service 
personnel to complete requirements for road maintenance and 
improvement under the National Environmental Policy Act and National 
Historic Preservation Act. The Coronado National Forest border liaison 
added that without this agreement, Forest Service would have been 
unable to meet Border Patrol's road maintenance needs in a timely 
fashion. 

In other situations, using Border Patrol resources to pay for or 
perform road maintenance may not always expedite access; instead, land 
managers and Border Patrol officials told us that a programmatic 
environmental impact statement should be prepared under the National 
Environmental Policy Act to help expedite access. For example, some 
patrol agents-in-charge, such as those in southwestern New Mexico, 
told us that to conduct environmental and historic property 
assessments on every road that agents might use, on a case-by-case 
basis, would take substantial time and require assessing hundreds, if 
not thousands, of miles of roads. Moreover, when agents request 
permission to move mobile surveillance systems, the request is often 
for moving such systems to a specific location, such as a 60-by-60-
foot area on a hill. Some agents told us, however, that it takes a 
long time to obtain permission from land managers because 
environmental and historic property assessments must be performed on 
each specific site, as well as on the road leading to the site. As we 
stated earlier, National Environmental Policy Act regulations 
recognize that programmatic environmental impact statements--broad 
evaluations of the environmental effects of multiple Border Patrol 
activities, such as road use and technology installation, in a 
geographic area--could facilitate compliance with the act. By 
completing a programmatic environmental impact statement, Border 
Patrol and land management agencies could then subsequently prepare 
narrower, site-specific statements or assessments of proposed Border 
Patrol activities on federal lands, such as on a mobile surveillance 
system site alone, thus potentially expediting access.[Footnote 25] 

Wilderness Act Restrictions Have Affected Three Stations' Access to 
Federal Lands: 

Patrol agents-in-charge for three stations reported that agents' 
access to some federal lands was limited because of restrictions in 
the Wilderness Act on building roads and installing infrastructure, 
such as surveillance towers, in wilderness areas. For these stations, 
the access restrictions lessen the effectiveness of agents' patrol and 
monitoring operations. However, land managers may grant permission for 
such activities if they meet the regulatory requirements for emergency 
and administrative use of motorized equipment and installations in 
wilderness areas. As shown in the following examples, land managers 
responsible for two wilderness areas are working with Border Patrol 
agents to provide additional access as allowed by the regulations for 
emergency and administrative use. On the other hand, a land manager 
responsible for a third wilderness area has denied some Border Patrol 
requests for additional access. 

* Cabeza Prieta National Wildlife Refuge, Arizona. At the Cabeza 
Prieta National Wildlife Refuge, Wilderness Act restrictions have 
limited the extent to which Border Patrol agents can use vehicles for 
patrols and technology resources to detect undocumented aliens. The 
patrol agent-in-charge responsible for patrolling Cabeza Prieta told 
us that the refuge has few roads. She told us that her agents' patrol 
operations would be more effective with one additional east-west road 
close to the border. Over 8,000 miles of roads and trails created by 
undocumented aliens and law enforcement activity throughout the 
refuge's wilderness have been identified by refuge staff; according to 
the patrol agent-in-charge, having an additional east-west road would 
give Border Patrol more options in using its mobile surveillance 
system to monitor significant portions of the refuge that are 
susceptible to undocumented-alien traffic. Additionally, the patrol 
agent-in-charge told us that better access could benefit the natural 
resources of the refuge because it could lead to more arrests closer 
to the border--instead of throughout the refuge--and result in fewer 
Border Patrol off-road incursions. The refuge manager agreed that 
additional Border Patrol access may result in additional environmental 
protection. He told us that he is working with Border Patrol to 
develop a strategy at the refuge that would allow Border Patrol to 
detect and apprehend undocumented aliens closer to the border. 
Further, the refuge manager in February 2010 gave permission for 
Border Patrol to install an SBInet tower on the refuge, which may also 
help protect the wilderness area. 

* Coronado National Forest, Arizona. In parts of the Coronado National 
Forest, Wilderness Act restrictions also limit the extent to which 
Border Patrol agents at one station can use vehicles to patrol parts 
of the forest and detect undocumented aliens. Specifically, patrol 
agents-in-charge of one station told us that their agents' access to 
part of the wilderness area has been limited--in large part because of 
the rugged terrain, but also because of restrictions on creating new 
roads in wilderness areas. According to Tucson Sector Border Patrol 
officials, more undocumented aliens cross the Coronado National Forest 
than any other federal land unit along the southwestern border, and 
much of this illegal traffic has recently shifted to a particular area 
of wilderness. Coronado National Forest officials told us they 
recognized the need for greater Border Patrol access and that such 
access could also help protect the forest's natural resources. As a 
result, according to Coronado National Forest officials, they approved 
the creation of four helicopter landing zones in the wilderness area 
because Forest Service wilderness regulations allow the agency to 
prescribe conditions for Border Patrol's use of motorized equipment 
and installations to protect the wilderness and its resources. 
Construction of these landing zones, however, has been delayed until 
2011, according to Coronado National Forest officials. In addition, 
Forest Service permitted Border Patrol to install technological 
resources--such as remote video surveillance systems and ground-based 
radar--in the rough terrain where road creation is infeasible, such as 
in the wilderness area.[Footnote 26] According to an agreement between 
Border Patrol and Coronado National Forest officials, installing this 
technology helps Border Patrol agents detect undocumented aliens and 
allows agents time to respond by helicopter, horseback, or all-terrain 
vehicle to apprehend undocumented aliens in these areas. 

* Organ Pipe Cactus National Monument, Arizona. Contrasting with the 
Cabeza Prieta refuge and the Coronado National Forest, when Border 
Patrol requested additional access in Organ Pipe's wilderness area, 
the monument's land manager determined that additional Border Patrol 
access would not necessarily improve protection of natural resources. 
For the Border Patrol station responsible for patrolling Organ Pipe, 
the patrol agent-in-charge told us that certain Border Patrol 
activities have been restricted because of the monument's status as 
wilderness, and Border Patrol's requests for additional access have 
been denied. Specifically, Border Patrol proposed placing an SBInet 
tower within the monument, and from the proposed site, the tower was 
expected to enable Border Patrol to detect undocumented aliens in a 30-
square-mile range. But because the proposed site was in a designated 
wilderness area, the land manager denied Border Patrol's request. 
Instead, Border Patrol installed the tower in an area within the 
monument that is owned by the state of Arizona. At this site, however, 
the tower has a smaller surveillance range and cannot cover about 3 
miles where undocumented aliens are known to cross, according to the 
patrol agent-in-charge, thus lessening Border Patrol's ability to 
detect entries compared with the originally proposed site. In 
addition, the patrol agent-in-charge explained that because of the 
tower's placement, when undocumented aliens are detected, agents have 
less time to apprehend them before they reach mountain passes, where 
it is easier to avoid detection. According to the land manager, he 
requested that Border Patrol find a different location for the tower 
because the Wilderness Act restricts placement of such infrastructure 
in wilderness areas. Further, he explained that Border Patrol did not 
demonstrate to him that the proposed tower site was critical, as 
compared with the alternative, and that agents' ability to detect 
undocumented aliens would be negatively affected. 

Endangered Species Act Requirements Have Affected Five Stations' 
Access to Federal Lands: 

Five Border Patrol stations reported that as a result of consultations 
required by section 7 of the Endangered Species Act, agents have had 
to adjust the timing or specific locales of their ground and air 
patrols to minimize the patrols' impact on endangered species and 
their critical habitats. As shown in the following examples, although 
some delays and restrictions have occurred, Border Patrol agents were 
generally able to adjust their patrols with little loss of 
effectiveness in their patrol operations. 

* Coronado National Forest, Arizona. For a Border Patrol station 
responsible for patrolling an area within the Coronado National 
Forest, the patrol agent-in-charge reported that a section 7 
consultation placed restrictions on helicopter and vehicle access 
because of the presence of endangered species. First, during parts of 
the year when certain endangered species are in residence, helicopter 
flight paths have been restricted. Nevertheless, the agent-in-charge 
told us, the restrictions, which result in alternative flight paths, 
do not lessen the effectiveness of Border Patrol's air operations. 
Moreover, according to the Forest Service District Ranger, since the 
area's rugged terrain presents a constant threat to agents' safety, 
Border Patrol agents have been allowed to use helicopters as needed, 
regardless of endangered species' presence.[Footnote 27] Second, the 
agent-in-charge told us, Border Patrol wanted to improve a road within 
the area to provide better access, but because of the proposed 
project's adverse effects an endangered plant, road improvement could 
not be completed near a low point where water crossed the road. Border 
Patrol worked with Forest Service officials to improve 3 miles of a 
Forest Service road up to the low point, but the crossing itself--
about 8 feet wide--along with 1.2 miles of road east of it was not 
improved. According to the agent-in-charge, agents still patrol the 
area but must drive vehicles slowly because of the road's condition 
east of the low point. 

* Cabeza Prieta National Wildlife Refuge, Arizona. The patrol agent-in-
charge of the station responsible for patrolling the Cabeza Prieta 
National Wildlife Refuge told us that as a result of section 7 
consultations, her helicopter patrols have been restricted when 
certain endangered species are known to be in an area. Once she hears 
from refuge staff about the endangered species' location, her agents 
adjust their air operations to patrol and pursue undocumented aliens 
farther north in the refuge. She told us that her agents' ability to 
detect and apprehend suspected undocumented aliens has not been 
compromised by these adjustments. Instead, she explained, 
communication with the refuge manager about the location of the 
endangered species is all that has been needed. According to the 
refuge manager, refuge staff are currently developing a system that 
will provide Border Patrol with "real-time" information on the 
endangered species' location, which they plan to complete before the 
end of the year. 

* San Bernardino National Wildlife Refuge, Arizona. For the Border 
Patrol station responsible for patrolling the San Bernardino National 
Wildlife Refuge, the patrol agent-in-charge told us that vehicle 
access has been restricted in the refuge because vehicle use can 
threaten the habitat of threatened and endangered species. Since 
establishment of the refuge in 1982, locked gates have been in place 
on the refuge's administrative roads (see figure 8).[Footnote 28] But 
Border Patrol station officials told us that in the last several 
years, with the increase in the number of agents assigned to the 
station, they wanted to have vehicle access to the refuge. The terms 
for vehicle access had to be negotiated with the refuge manager 
because of the access restrictions imposed to protect endangered 
species habitat. The patrol agent-in-charge told us that Border Patrol 
and the refuge manager agreed to place Border Patrol locks on refuge 
gates and to allow second-level Border Patrol supervisors, on a case-
by-case basis, to determine whether vehicle access to the refuge is 
critical.[Footnote 29] If such a determination is made, a Border 
Patrol supervisor unlocks the gate and contacts refuge staff to inform 
them that access was granted through a specific gate. The patrol agent-
in-charge told us that operational control has not been affected by 
these conditions for vehicle access. Nevertheless, he said, additional 
technology, such as mobile surveillance systems, would be helpful in 
detecting undocumented aliens in the remote areas in and around the 
refuge.

Refuge:

Most Agents Reported That Land Management Laws Have Had No Effect on 
Border Patrol's Overall Measure of Border Security: 

Despite the access delays and restrictions reported for 17 stations, 
most patrol agents-in-charge whom we interviewed said that the border 
security status of their jurisdictions has been unaffected by land 
management laws. Instead, factors other than access delays or 
restrictions, such as the remoteness and ruggedness of the terrain or 
dense vegetation, have had the greatest effect on their abilities to 
achieve or maintain operational control. While four patrol agents-in- 
charge reported that delays and restrictions negatively affected their 
ability to achieve or maintain operational control, they have either 
not requested resources to facilitate increased or timelier access or 
have had their requests denied by senior Border Patrol officials, who 
said that other needs were greater priorities for the station or 
sector. 

Most Stations' Border Security Status Has Been Unaffected by Land 
Management Laws; Instead, Stark Terrain Features Have Had the Greatest 
Effect: 

Patrol agents-in-charge at 22 of the 26 stations along the 
southwestern border told us that their ability to achieve or maintain 
operational control in their areas of responsibility has been 
unaffected by land management laws; in other words, no portions of 
these stations' jurisdictions have had their border security status, 
such as "controlled," "managed," or "monitored," downgraded as a 
result of land management laws. Instead, for these stations, the 
primary factor affecting operational control has been the remoteness 
and ruggedness of the terrain or the dense vegetation their agents 
patrol and monitor. Specifically, patrol agents-in-charge at 18 
stations told us that stark terrain features--such as rocky mountains, 
deep canyons, and dense brush--have negatively affected their agents' 
abilities to detect and apprehend undocumented aliens. A patrol agent-
in-charge whose station is responsible for patrolling federal land in 
southern California told us that the terrain is so rugged that Border 
Patrol agents must patrol and pursue undocumented aliens on foot; even 
all-terrain vehicles specifically designed for off-road travel cannot 
traverse the rocky terrain. He added that because of significant 
variations in topography, such as deep canyons and mountain ridges, 
surveillance technology can also be ineffective in detecting 
undocumented aliens who hide there (see figure 9). 

Figure 9: Terrain in One Rocky Wilderness Area:

[End of figure] 

In addition, patrol agents-in-charge responsible for patrolling 
certain Fish and Wildlife Service land reported that dense vegetation 
limits agents' ability to patrol or monitor much of the land. One 
agent explained that Border Patrol's technology resources were 
developed for use in deserts where few terrain features obstruct 
surveillance, whereas the vegetation in these areas is dense and 
junglelike (see figure 10). 

Figure 10: Dense, Semitropical Forest in a National Wildlife Refuge:

[End of figure] 

Most patrol agents-in-charge also told us that the most important 
resources for achieving and maintaining operational control are (1) a 
sufficient number of agents; (2) additional technology resources, such 
as mobile surveillance systems; and (3) tactical infrastructure, such 
as vehicle and pedestrian fencing. For example, in the remote areas of 
one national wildlife refuge, a patrol agent-in-charge told us that 
even with greater access in the refuge, he would not increase the 
number of agents patrolling it to gain improvements in operational 
control. Instead, he said, additional technology resources, such as a 
mobile surveillance system, would be more effective in achieving 
operational control of the area because such systems would assist in 
detecting undocumented aliens while allowing agents to maintain their 
presence in and around a nearby urban area, where the vast majority of 
illegal entries occur. His view, and those of other patrol agents-in- 
charge whom we interviewed, is underscored by Border Patrol's 
operational assessments--twice-yearly planning documents that stations 
and sectors use to identify impediments to achieving or maintaining 
operational control and to request resources needed to achieve or 
maintain operational control.[Footnote 30] In these assessments, 
stations have generally requested additional personnel or technology 
resources for their operations on federal lands. Delays or 
restrictions in gaining access have generally not been identified in 
operational assessments as an impediment to achieving or maintaining 
operational control for the 26 stations along the southwestern border. 

For Four Stations Reporting That Their Security Status Has Been 
Affected by Land Management Laws, Agents Have Either Not Requested 
Additional Access or Have Had Such Requests Denied by Senior Border 
Patrol Officials: 

Of the 26 patrol agents-in-charge we interviewed, 4 reported that 
delays and restrictions in gaining access to federal lands have 
negatively affected their ability to achieve or maintain operational 
control: 2 of these 4 agents reported not having used Border Patrol's 
operational assessments to request resources to facilitate increased 
or timelier access, and the other 2 reported having had such requests 
denied by either Border Patrol sector or headquarters officials. For 
example, the patrol agent-in-charge responsible for an area in 
southwestern New Mexico told us that operational control in a remote 
area of his jurisdiction is partly affected by the scarcity of roads. 
Specifically, having an additional road in this area would allow his 
agents to move surveillance equipment to an area that, at present, is 
rarely monitored. Nevertheless, a supervisory agent for the area told 
us, station officials did not request additional access through Border 
Patrol's operational assessments. The 2006 memorandum of understanding 
directs Border Patrol to consult with land managers when developing 
operational assessments if Border Patrol needs additional access on 
federal lands.[Footnote 31] Land managers in this area told us they 
would be willing to work with Border Patrol to facilitate such access, 
if requested. 

Similarly, the patrol agent-in-charge at a Border Patrol station 
responsible for patrolling another federal land unit also reported 
that his ability to achieve operational control is affected by a 
shortage of east-west roads in the unit. He told us that some of his 
area of operation could potentially reach operational control status 
if there were an additional east-west road for patrolling certain 
areas within the unit to detect and apprehend undocumented aliens. 
Border Patrol requested an additional east-west road, but the land 
manager denied the request because the area is designated wilderness, 
according to the agent-in-charge.[Footnote 32] The agent explained 
that he did not use the operational assessment to request additional 
roads because the land manager denied his initial request. The land 
manager told us that he would be willing to work with Border Patrol to 
facilitate additional access if it could be shown that such access 
would help increase deterrence and apprehensions closer to the border. 

For the other two stations reporting that federal land management laws 
have negatively affected their ability to achieve or maintain 
operational control, Border Patrol sector or headquarters officials 
have denied the stations' requests for resources to facilitate 
increased or timelier access--typically for budgetary reasons. For 
example, one patrol agent-in-charge reported that 1.3 miles of border 
in her area of responsibility are not at operational control because, 
unlike most other border areas, it has no access road directly on the 
border. Further, she explained, the rough terrain has kept Border 
Patrol from building such a road; instead, a road would need to be 
created in an area designated as wilderness. According to the patrol 
agent-in-charge, her station asked Border Patrol's sector office for 
an access road, and the request was submitted as part of the 
operational requirements-based budgeting program. As of July 2010, the 
request had not been approved because of budgetary constraints, 
according to the agent-in-charge. In addition, another patrol agent-in-
charge told us, few roads lie close to the river that runs through his 
area of responsibility. As a result, his agents have to patrol and 
monitor nearly 1 mile north of the international border, much closer 
to urban areas. According to officials with Border Patrol's relevant 
sector office, they have been using the operational assessments for 
several years to request an all-weather road, but approval and funding 
have not been granted by Border Patrol's headquarters. 

Some Federal Land Managers Have Collected and Used Selected Data on 
the Environmental Effects of Cross-Border Illegal Activity to Manage 
Federal Borderlands: 

While federal land managers along the southwestern border receive data 
collected by Border Patrol on the extent of cross-border illegal 
activities on their lands, the extent of land managers' data 
collection efforts on the effects of these illegal activities has 
varied among land units, with some land managers regularly monitoring 
areas to determine resource impacts, others documenting environmental 
damage on an ad hoc basis, and still others collecting no such data. 
Where collected, land managers have used data on the environmental 
effects of cross-border illegal activity, as well as data provided by 
Border Patrol on the extent of cross-border illegal activity, for 
several land management and conservation purposes. These purposes 
include (1) restoring lands and mitigating environmental damage, (2) 
providing Border Patrol agents with environmental and cultural 
awareness training, (3) protecting staff and visitors, and (4) 
establishing conservation measures to reduce adverse effects of Border 
Patrol actions on endangered species and their habitats. 

Land Managers Rely on Border Patrol for Data on Cross-Border Illegal 
Activity; the Extent of Their Data Collection Efforts on the 
Environmental Effects of Such Activity Has Varied: 

Land managers generally rely on Border Patrol for data on cross-border 
illegal activity, including data on apprehensions of undocumented 
aliens and drug seizures occurring on federal lands. In accordance 
with the 2006 memorandum of understanding, Border Patrol officials 
share data with land managers, and officials have done so in a variety 
of ways, including at regular meetings and in e-mailed reports. For 
example, Border Patrol provides statistics on apprehensions and drug 
seizures to land managers during the monthly meetings of borderlands 
management task forces. Formed in each Border Patrol sector along the 
southwestern border, these task forces serve as a forum for Border 
Patrol and land managers, among others, to discuss and share 
information on border-related issues on public lands. During these 
meetings, Border Patrol has typically provided written statistics on 
cross-border illegal activity occurring on federal land units 
throughout each sector. 

The extent of land managers' efforts to collect data on the 
environmental effects of cross-border illegal activity along the 
southwestern border has varied, with some land managers (5 of 18) 
regularly collecting and analyzing data on the environmental effects 
of cross-border illegal activity, including acres burned by wildland 
fires, miles of trampled vegetation from illegal trails, and amounts 
of trash collected. Other land managers (10 of 18) reported having 
collected data on an irregular basis. Still other land managers (3 of 
18) reported having collected no such data. 

Examples of ongoing efforts by land managers to collect and analyze 
these kinds of data include the following: 

* At Organ Pipe Cactus National Monument, land managers have conducted 
a semiannual inventory and monitoring program since 2002 to assess the 
extent of natural and cultural resource damage from cross-border 
illegal activity. The land managers delineate and walk five east-west 
lines, or transects, that cross known illegal trafficking routes, and 
along each transect, monument staff have recorded and mapped resource 
impacts, such as trails, trash, and fire scars. 

* Land managers from the Cleveland National Forest in California have 
annually collected and reported a variety of data on environmental 
impacts, which show that since 2002, nearly 59,000 pounds of trash 
left by undocumented aliens have been collected, and over 19,000 acres 
of forest have burned from fires started by undocumented aliens. 

* The Bureau of Land Management, through its restoration work on 
federal lands throughout southern Arizona, has annually collected data 
since 2003 on the quantities of trash, vehicles, and bicycles removed 
from public land and acres of land restored. 

* Land managers from the Cabeza Prieta National Wildlife Refuge have 
collected data annually since 2005 on illegal trails, damaged 
vegetation, and sites with large amounts of trash. They collect these 
data along 12 transects established by refuge staff, which are 
traveled on foot by volunteers and refuge staff who record information 
on environmental impacts. Cabeza Prieta has also inventoried the 
damage caused by foot and vehicle traffic, mapped smuggling routes 
through the refuge, and assessed priorities for restoration. 

Other land managers' data collection has been done with less 
regularity. For example, land managers from the Fish and Wildlife 
Service's South Texas Refuge Complex--which includes the Laguna 
Atascosa, Santa Ana, and Lower Rio Grande Valley national wildlife 
refuges--told us that although they do not regularly collect data on 
the environmental impacts of cross-border illegal activity, their 
staff has estimated that thousands of illegal trails and tons of trash 
and human waste have been found on the three wildlife refuges within 
the complex. In addition, at the Coronado National Memorial in 
Arizona, land managers have at times mapped the major trails used by 
undocumented aliens through the monument, taken aerial and satellite 
photos to document damage, and documented disturbances to the foraging 
habitat of the endangered lesser long-nosed bat. 

Three land managers we spoke with had not made any formal effort to 
collect data on the environmental effects of cross-border illegal 
activity, although they believed that adverse environmental effects 
were occurring. A land manager with the Bureau of Land Management's 
Las Cruces office in New Mexico said that his office had requested 
funding to collect data on the environmental effects of increased 
human presence on bureau lands--including inventorying and documenting 
the extent of illegal trails, trash, and impacts to animal species--
but had received no funding to carry out these data collection efforts. 

In addition to collecting data on the environmental impacts of cross- 
border illegal activity, land managers in some areas have also 
collected data on the environmental effects of Border Patrol's 
response to cross-border illegal activities. For example, land 
managers for Organ Pipe Cactus National Monument and Cabeza Prieta 
National Wildlife Refuge have created maps showing the extent of off-
road vehicle travel by Border Patrol agents. Such travel can disrupt 
endangered species and damage vegetation, soils, and water runoff 
patterns, according to these land managers.[Footnote 33] 

Land Managers Have Used Environmental and Other Data for Managing 
Federal Borderlands: 

Land managers use data they have collected on the environmental 
effects of cross-border illegal activity, as well as data provided by 
Border Patrol on the extent of cross-border illegal activity, for 
several purposes, including (1) restoring lands and mitigating 
environmental damage, (2) providing Border Patrol agents with 
environmental and cultural awareness training, (3) protecting staff 
and visitors, and (4) establishing conservation measures to reduce 
adverse effects of Border Patrol actions on endangered species and 
their habitats. 

Restoring Lands and Mitigating Environmental Damage: 

Some land managers have used environmental data and data on cross- 
border illegal activity to help restore lands damaged by undocumented 
aliens. For example, since 2003, the Bureau of Land Management has 
been working with federal, state, and tribal partners to administer 
the Southern Arizona Project.[Footnote 34] Through this project, 
partners have coordinated and executed cleanup and restoration 
activities throughout southern Arizona. In fiscal year 2009, for 
example, participants in the Southern Arizona Project removed 468,000 
pounds of trash, 62 vehicles, and 404 bicycles and restored 650 acres 
of land that were damaged by illegal traffic (see figure 11). The 
Bureau of Land Management reported that the project focused its 
remediation effort on restoring illegally created roads and trails, 
which included grading the disturbed sites, removing invasive brush, 
and reseeding areas with native plants.

Land managers with Interior have also used selected data to identify 
and select natural resource projects to offset the environmental 
impacts of constructing pedestrian and vehicle fences. The Illegal 
Immigration Reform and Immigrant Responsibility Act of 1996 mandated 
installation of additional physical barriers and roads near the 
border, including 14 miles of additional fencing near San Diego, 
California. The act waived the provisions of the Endangered Species 
Act and the National Environmental Policy Act to the extent that the 
U.S. Attorney General determined necessary to ensure expeditious 
construction of barriers and roads. The REAL ID Act of 2005 amended 
the 1996 act to authorize the Secretary of Homeland Security to waive 
all legal requirements that the Secretary, at his or her sole 
discretion, determines necessary to ensure expeditious construction. 
[Footnote 35] In 2007, the act was amended again to require, among 
other things, that the Secretary (1) construct not less than 700 miles 
of fencing along the southwestern border where such fencing would be 
most practical and effective and (2) consult widely, including with 
the Secretaries of the Interior and Agriculture, to minimize the 
impact of the fencing on the environment, among other things.[Footnote 
36] In instances where the Secretary invoked this waiver authority, 
DHS voluntarily prepared plans--termed environmental stewardship 
plans--estimating the expected environmental impacts of particular 
fencing segments and worked with Interior to develop strategies to 
reduce or minimize adverse environmental impacts. Where adverse 
environmental impacts such as habitat loss, heavy sedimentation, or 
erosion could not be minimized or averted, DHS committed funding to 
allow Interior to carry out appropriate mitigation measures (see 
figure 12). Using the environmental stewardship plans to identify 
appropriate mitigation measures, DHS committed up to $50 million to 
Interior for implementing such measures.[Footnote 37] Interior in turn 
was to identify $50 million worth of projects to benefit threatened 
and endangered species and their habitats. Projects identified by 
Interior include acquiring land for the endangered Otay Mountain 
arroyo toad in California and implementing jaguar monitoring and 
conservation projects across Arizona and New Mexico (see appendix II 
for the complete list of mitigation projects). According to Interior 
and DHS officials, Interior and DHS signed an agreement on September 
28, 2010, for the transfer of $6.8 million to mitigate impacts on 
endangered species along the southwestern border. This agreement is 
the first of several anticipated over the next year to transfer funds 
totaling $50 million from DHS to Interior for such mitigation 
projects, according to an Interior official.

California, for Which DHS Is Providing Funding to Mitigate the Loss of

Providing Border Patrol Agents with Training: 

Some land managers told us they have used information on the 
environmental effects of cross-border illegal activity to design and 
provide training to Border Patrol agents on ways to minimize 
environmental damage that their response to illegal activities may 
cause, in accordance with the 2006 memorandum of 
understanding.[Footnote 38]Twenty of the 26 patrol agents-in-charge we 
interviewed told us that their agents received training from land 
managers in the form of either in-person training, training tools such 
as videos, or both.[Footnote 39] All 20 patrol agents-in-charge 
reported that the training provided by land managers had increased 
their agents' awareness of the potential resource effects of their 
patrol operations and some said that this increased awareness has led 
agents to modify their patrols. For example, 10 patrol agents in 
charge said that their agents' increased environmental awareness had, 
for example, helped reduce off-road driving in environmentally 
sensitive areas and that, when possible, agents were more likely to 
use foot or horse patrols instead of vehicle patrols. 

Nevertheless, many patrol agents-in-charge reported wanting more 
frequent, land unit-specific, in-person training for their agents. For 
example, 11 patrol agents-in-charge reported wanting more frequent 
training, including regular refresher training, and suggested 
frequencies for this training that ranged from quarterly to annually. 
Further, 10 patrol agents-in-charge reported that having information 
delivered by land managers was the clearest, most effective way to 
communicate with agents. Three patrol agents-in-charge also said they 
would like training to be area-specific, meaning that the training 
should describe the specific natural and cultural resources of the 
area they patrol. Land managers and other officials told us that 
limited resources and competing priorities, combined with the high 
rate of turnover among Border Patrol agents, can make it difficult to 
provide timely, in-person training on a regular basis. 

Recognizing the need for natural and cultural resource training for 
Border Patrol agents, DHS, Interior, and the Forest Service in 2009 
formed a task force on environmental and cultural stewardship 
training. Officials of these agencies told us that the task force is 
developing a content outline for a national training module and has 
collected nationwide information on training that land managers have 
provided to Border Patrol stations, discussed requirements for the 
national module, and discussed an overall strategy for implementing 
the module. As of September 2010, the task force had not made any 
decisions on what information the training module is to include and 
had not asked staff in the field what their needs for training content 
were, according to DHS and Interior officials involved in developing 
the training. But as we have previously reported, stakeholder 
involvement throughout the planning and development of such a training 
program contributes to accomplishing the agencies' missions and goals. 
[Footnote 40] Adopting core characteristics of a strategic training 
and development process can also help ensure that agencies' training 
investments are targeted strategically and not directed toward efforts 
that are irrelevant, duplicative, or ineffective. 

Protecting Staff and Visitors: 

Some land managers have also used data provided by Border Patrol on 
cross-border illegal activity to help make decisions related to staff 
and visitor safety. For example, managers of some federal lands have 
placed signs warning the public that they may encounter cross-border 
illegal activity, or they have distributed border safety awareness 
flyers at visitor centers and trailheads (see figures 13 and 14).

In some cases, federal land managers have closed portions of their 
lands to the public and restricted staff access to certain areas 
unless accompanied by law enforcement agents. As illustrated by the 
following examples, Interior and the Forest Service have faced 
numerous challenges providing a safe environment for visitors, 
employees, and residents on federal lands along the southwestern 
border: 

* In 2002 at Organ Pipe Cactus National Monument, a drug smuggler shot 
and killed a park ranger. Following this and other reports of 
increasing violence, about half of the monument has been closed to the 
public since 2007. 

* In 2005, five undocumented aliens were murdered at Buenos Aires 
National Wildlife Refuge in Arizona. As the result of illegal activity 
and heavy law enforcement action, about 3,500 acres have been closed 
to the public since 2006. 

* In a 2006 testimony, the supervisor of Cleveland National Forest 
stated that armed bandits had threatened, robbed, raped, and assaulted 
undocumented aliens traveling through the forest and that money, 
firearms, and other personal possessions had been taken from national 
forest employee and private residences. 

* Since 2007, Cabeza Prieta National Wildlife Refuge has been 
requiring law enforcement escorts for refuge staff and volunteers 
working within several miles of the border. 

* In 2009, the South Texas Refuge Complex reported that many refuge 
tracts adjacent to the Rio Grande were closed to visitors in part 
because of illegal immigration, human smuggling, and drug smuggling. 
[Footnote 41] 

In addition, the Fish and Wildlife Service reported in a 2007 internal 
document that it had not done enough to inform the public and key 
political officials about the dangers presented by cross-border 
smuggling activities. Illustrating this shortcoming, Fish and Wildlife 
Service South Texas Refuge Complex officials told us that refuge staff 
will tell visitors--when asked--of potential border issues during 
their visit, but that no standard public notification system exists, 
such as handouts, signs, or other means. 

Interior lacks a nation or borderwide system to analyze trends in 
illegal activity, according to department headquarters officials. 
These officials told us, however, that Interior is in the early stages 
of developing an incident management analysis and reporting system to 
provide a method for collecting, analyzing, and reporting information 
on illegal activity from all bureaus. Furthermore, these officials 
explained that this system is to assist officials in making staff and 
visitor safety decisions on Interior lands. 

Establishing Conservation Measures to Reduce Adverse Effects to 
Endangered Species and Their Habitats: 

The Fish and Wildlife Service has also used data related to the 
environmental impacts of cross-border illegal activity to prepare 
biological opinions that establish measures to reduce adverse 
potential effects of Border Patrol actions on endangered species and 
their critical habitats along the southwestern border. For example, in 
a 2009 biological opinion, the Fish and Wildlife Service analyzed data 
on Border Patrol agents' off-road vehicle use, routine activities at 
bases of operations, and road dragging, among other activities. They 
determined that these activities disturbed a certain endangered 
species and that establishment of a Border Patrol base of operations--
including housing, lighting, parking, fuel, and generators for agents 
stationed at the base--contributed to the disturbance of the species 
by disrupting its traditional travel route. To mitigate these and 
other adverse impacts, Border Patrol agreed that no aircraft use, off-
road vehicle travel, or other activities would occur within a quarter-
mile of areas important for the species, except in emergency 
situations as defined by the 2006 memorandum of understanding. 

In south Texas, the Fish and Wildlife Service analyzed data on Border 
Patrol activities--including portable and permanent lighting, clearing 
of vegetation for patrol roads, and ports of entry, and patrolling 
activities along the Rio Grande. The Fish and Wildlife Service 
determined that these activities have fragmented and reduced the 
amount of habitat suitable for the endangered ocelot. To minimize 
impacts to the ocelot and other species, Border Patrol agreed to a 
variety of measures, including working cooperatively with the Fish and 
Wildlife Service to identify lighting sites that would use 450-watt 
bulbs instead of 1,000-watt bulbs and reducing the number of roads 
through the river corridor to reduce habitat fragmentation. 

The Fish and Wildlife Service also collected data on the environmental 
effects that construction, operation, and maintenance of SBInet towers 
in the Tucson Sector--including the construction and repair of roads 
and the placement of underground sensors--would have on several 
threatened and endangered species, including the Chiricahua leopard 
frog, Mexican spotted owl and its critical habitat, jaguar, lesser 
long-nosed bat, and Pima pineapple cactus. Land managers collected 
data on a range of impacts on these species, including habitat 
disturbance and loss; loss of foraging habitat; disturbance from 
nighttime lights and noise associated with construction, generators, 
and helicopter landings; and the potential to introduce nonnative 
plant species that contribute fuel to wildland fires. To minimize 
these impacts, Border Patrol has participated in several species' 
recovery plans, to close and restore unauthorized roads to help offset 
the increase in new or improved roads, and to fund monitoring efforts 
for some species. 

Conclusions: 

The steady northward flow of illegal human and narcotics traffic 
across the nation's southwestern border shows no sign of stopping, and 
Border Patrol retains and asserts the ability to pursue undocumented 
aliens when and how it sees fit. Certain land management laws present 
some challenges to Border Patrol's operations on federal lands, 
limiting to varying degrees the agency's access to patrol and monitor 
some areas. With limited access for patrols and monitoring, some 
illegal entries may go undetected. This challenge can be exacerbated 
as illegal traffic shifts to areas where Border Patrol has previously 
not needed, or requested, access. Although mechanisms established in 
the 2006 memorandum of understanding provide a framework for Border 
Patrol and the federal land management agencies to resolve access 
issues, some issues remain unresolved. This lack of resolution remains 
because land management agencies have not always been able to complete 
required environmental and historic property assessments in a timely 
fashion--often because of limited resources or competing priorities--
and the agencies have not taken advantage of resources that Border 
Patrol may have to offer to more quickly initiate these assessments. 
Moreover, conducting these required assessments on a case-by-case 
basis and without programmatic environmental impact statements to 
facilitate compliance with the National Environmental Policy Act may 
be a missed opportunity to expedite Border Patrol's access to federal 
borderlands. 

Border Patrol agents and land managers agree that Border Patrol's 
presence is needed to protect natural and cultural resources on 
federal lands because, for instance, fewer illegal entries means less 
human traffic over environmentally sensitive areas. What agents 
perceive as routine patrol operations, however, can also have a 
lasting negative effect on the environment. Border Patrol has provided 
its new agents with some basic environmental training, but such 
training often is neither recurring nor specific to the land units 
that agents patrol. Land managers, on the other hand, have the natural 
and cultural resource expertise to share with agents about the 
potential environmental effects of their operations. Without more 
frequent and area-specific environmental and cultural resource 
training by land managers, Border Patrol agents may lack the awareness 
to modify their patrols in environmentally sensitive areas. 

Recommendations for Executive Action: 

To improve the effectiveness of Border Patrol operations while also 
protecting cultural and natural resources on federal lands along the 
southwestern border, we recommend that the Secretaries of Homeland 
Security, the Interior, and Agriculture take the following two actions: 

* To help expedite Border Patrol's access to federal lands, the 
agencies should, when and where appropriate, (a) enter into agreements 
that provide for Customs and Border Protection to use its own 
resources to pay for or to conduct the required environmental and 
historic property assessments and (b) prepare programmatic National 
Environmental Policy Act documents for Border Patrol activities in 
areas where additional access may be needed. 

* As DHS, Interior, and the Forest Service continue developing a 
national training module on environmental and cultural resource 
stewardship, the agencies should incorporate the input of Border 
Patrol agents and land managers into the design and development of 
training content, which may include training that is recurring, area-
specific, and provided by land managers.

Appendix I: Objectives, Scope, and Methodology: 

Our objectives were to (1) describe the key land management laws 
Border Patrol operates under and how Border Patrol and land management 
agencies coordinate their responsibilities under these laws, (2) 
examine how Border Patrol operations are affected by these laws, and 
(3) identify the extent to which land management agencies collect data 
related to cross-border illegal activities and associated 
environmental impacts and how these data are used. 

To describe the key land management laws Border Patrol operates under 
and how Border Patrol and land management agencies coordinate their 
responsibilities under these laws, we examined agency documents 
describing the laws that apply to Border Patrol operations on federal 
lands along the southwestern border and documents describing how 
Border Patrol and land management agencies are to coordinate their 
responsibilities under these laws. We corroborated our selection of 
key laws through interviews with Border Patrol, the Department of the 
Interior, and U.S. Forest Service officials in headquarters and at 
field units. To determine how Border Patrol and land management 
agencies coordinate their responsibilities under these laws, we 
interviewed relevant agency officials; reviewed local agreements, 
including documentation from local working groups and forums, and 
documentation related to a legal settlement over Border Patrol 
activities in a certain area with endangered species; and we reviewed 
the provisions of the 2006 interagency memorandum of understanding 
between the Department of Homeland Security (DHS), Interior, and the 
Department of Agriculture. In our interviews with Border Patrol agents 
and land managers, we determined how these various coordinating 
mechanisms have helped the agencies implement their respective legal 
responsibilities. 

To examine how Border Patrol's operations are affected by the laws we 
identified, we conducted selected site visits to 10 federal land units 
in Arizona, California, and Texas and to Border Patrol stations 
responsible for patrolling these units. We selected these units, and 
the stations responsible for patrolling them, on the basis of 
geographical diversity, the extent of and impact from cross-border 
illegal activity, and the type of land management agency. Further, we 
conducted telephone interviews with land managers for federal land 
units along the border that we did not visit, including those in New 
Mexico. In total, we interviewed land managers responsible for 18 
federal land units along the southwestern border. Although the 
information we obtained is not generalizable to all land units, it 
represents a full spectrum of information available on the extent of 
and impact from cross-border illegal activity. In addition, we 
developed and used a structured interview to obtain the views of 
Border Patrol patrol agents-in-charge of the 26 Border Patrol stations 
in the borderlands region with primary responsibility for patrolling 
federal lands along the southwestern border. We surveyed these agents 
on whether and to what extent their operations have been affected by 
land management laws.[Footnote 42] We also analyzed documentation on 
how Border Patrol measures the effectiveness of its operations and 
reviewed 2 years (2009 and 2010) of Border Patrol operational 
assessments. 

To examine the extent to which land managers collect data related to 
cross-border illegal activities and associated environmental impacts 
and how these data are used, we obtained a variety of data from land 
managers. Specifically, we identified what kinds of data land managers 
have collected and what kinds of data they have relied on Border 
Patrol to provide, and we reviewed the varying quantities and types of 
data that land managers had on the environmental effects of cross-
border illegal activities. We also reviewed data that land managers 
have collected on the environmental effects of Border Patrol's 
response to cross-border illegal activities, such as constructing 
fences and using vehicles off established roads to pursue suspected 
undocumented aliens. We also used information from our structured 
interviews with Border Patrol agents. Additionally, we obtained 
environmental data that DHS and land managers used to determine 
funding for mitigation efforts related to environmental damage caused 
by certain DHS border fencing projects. Through our interviews with 
land managers and reviews of their data collection efforts, we 
analyzed the various ways that land managers have used data on cross-
border illegal activity and its environmental impacts. This analysis 
included reviewing how land managers have used data to set priorities 
for and carry out cleanup and restoration work, reviewing the various 
types of environmental stewardship training provided by land managers 
to Border Patrol agents, reviewing numerous biological opinions 
related to Border Patrol activities, and documenting various ways land 
managers help ensure staff and visitor safety on federal lands. We 
corroborated these data by obtaining and reviewing them where possible. 

We conducted this performance audit from December 2009 to October 
2010, in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives.

Appendix III: Comments from the Department of Homeland Security:

Ms. Anu K. Mittal: 
Director: 
Natural Resources and Environment: 
Government Accountability Office: 
Washington, D.C. 20548: 

Dear Ms. Mittal: 

Thank you for the opportunity to review and offer comment on the 
Government Accountability Office (GAO) draft report entitled, 
"Southwest Border: More Timely Border Patrol Access and Training Could 
Improve Security Operations and Natural Resource Protection on Federal 
Lands," GA0-11-38, dated November 2010. GAO was asked to examine (1) 
key land management laws Border Patrol operates under and how it and 
land management agencies coordinate their responsibilities under these 
laws, (2) how Border Patrol operations are affected by these laws, and 
(3) the extent to which land management agencies collect and use data 
related to the environmental effects of illegal activities, such as 
human trafficking and drug smuggling. 

GAO reported that Border Patrol's access on some federal lands along 
the southwestern border has been limited because of certain land 
management laws, resulting in delays and restrictions in agents' 
patrolling and monitoring portions of these lands. GAO concluded that 
with limited access for patrols and monitoring, some illegal entries 
may go undetected. GAO also stated that although mechanisms 
established in the 2006 memorandum of understanding provide a 
framework for Border Patrol and the federal land management agencies 
for resolving access issues, some issues remain unresolved, While 
federal land managers in the borderlands region rely on Border Patrol 
to collect data on the extent of cross-border illegal activities on 
their lands, the extent of their data collection efforts on the 
effects of these illegal activities has varied. 

U.S. Customs and Border Protection (CBP) concurs with GAO's 
conclusions and believes that overall, the report is balanced, fair, 
and well written. The Department of Homeland Security (DHS) is fully 
committed to a positive working relationship with the Department of 
the Interior (Interior) and the U.S. Forest Service (USFS). We respect 
the missions of these agencies and we recognize the importance of the 
preservation of the American landscape. We acknowledge that balancing 
the requirements of border enforcement and land preservation can at 
times present challenges, but we are committed to collaboration with 
Interior and the USFS to find workable solutions on special status 
lands. DHS's close working relationship with Interior and USFS allows 
DHS to fulfill its enforcement responsibilities while respecting and 
enhancing the environment. 

GAO made two recommendations to the Secretaries of Homeland Security, 
Interior, and U.S. Department of Agriculture (USDA) to improve the 
effectiveness of Border Patrol operations while also protecting 
cultural and natural resources on federal lands along the southwestern 
border. CBP concurs with the two recommendations. 

The recommendations and CBP's corrective actions to address the 
recommendation are described below. 

Recommendation 1: To help expedite Border Patrol's access to federal 
lands, the agencies should, when and where appropriate, (a) enter into 
agreements that provide for Border Patrol to use its own resources to 
pay for or to conduct the required environmental and historic property 
assessments and (b) prepare programmatic environmental impact 
statements for Border Patrol activities in areas where additional 
access may be needed. 

Response: Concur. 

The current language specifies that Border Patrol should conduct and 
pay for environmental plans. This should be changed to CBP, rather 
than Border Patrol. Complementarily, CBP believes that the federal 
land manager agencies should be adequately funded to perform 
environmental studies that are within their mission and 
responsibilities. 

CBP already incorporates operational requirements into National 
Environmental Policy Act documents for projects where it is 
appropriate. In addition, CBP has a programmatic environmental 
document for the Southwest border that was produced several years ago. 
Furthermore, CBP started the programmatic environmental document for 
northern border this year to address CBP operations. 

Due Date: October 2011. 

Recommendation 2: As DHS, Interior, and the Forest Service continue 
developing a national training module on environmental and cultural 
resource stewardship, the agencies should incorporate the input of 
Border Patrol agents and land managers into the design and development 
of the training content, which may include training that is recurring, 
area-specific, and provided by land managers. 

Response: Concur. 

Understanding the importance of cooperation and active participation, 
the tri-agency Environmental and Cultural Stewardship Training (ECST) 
module is being jointly developed by OHS, Interior, and the U.S. 
Forest Service within USDA. The goal of developing this national 
module is to provide a basic fundamental training tool that will be 
made available to all Border Patrol agents early in their career as 
well as other employees of CBP, as appropriate. The final product, a 
web-based course, will enable Border Patrol agents and other CBP 
components to operate conscientiously and effectively while also 
incorporating environmental and cultural resources stewardship 
practices into their daily operational activities. OBP believes that 
by increasing interagency knowledge we will further ensure more robust 
partnerships and strengthen the missions of all three agencies. 

Development of this training module is being overseen by the ECST Task 
Force. This ongoing taskforce, comprised of senior officials from DHS, 
Interior, and USDA, was initially established in 2009 by the U.S. 
Border Patrol. The mission of the ECST Task Force is to work 
cooperatively to build on existing environmental and cultural 
resources stewardship training currently being delivered to Border 
Patrol agents and other CBP components. 

Impetus to develop this national training module was provided by the 
Memorandum of Understanding (MOU) regarding Cooperative National 
Security and Counterterrorism Efforts on Federal Lands along U.S. 
borders. This MOU was signed in March 2006 by the Secretaries of the 
DHS, Interior and USDA. More specifically, it calls for Interior and 
USDA to "provide CBP-BP agents with appropriate environmental and 
cultural integrity training formatted to meet CBP-BP operational 
constraints." The ECST national training module is the product that 
resulted from this tri-agency cooperation. 

The contents of the training module will be on a broad, national-level 
that is useful and applicable to all regions along the U.S. borders. 
This national training module is intended to complement and augment 
the wide variety of already existing, but targeted and location-
specific training products. 

From its inception, the module has incorporated the input of Border 
Patrol agents and land managers into its design and will continue to 
do so as it is developed and piloted. Subject matter experts from all 
three agencies will continue to solicit feedback to ensure a robust 
field perspective. Coordination of the module's development is being 
carried out by the CBP Office of Training and Development. 

Due Date: June 2011.

Dear Ms. Mittal: 

Thank you for the opportunity to review and provide comment on the 
draft U.S. Government Accountability Office (GAO) Report on "Southwest 
Border: More Timely Border Patrol Access and Training Could Improve 
Security Operations and Natural Resource Protection on Federal Lands 
(GAO-11-38)." The Forest Service has reviewed the report and generally 
concurs with the report's observations and recommendations. 

The Forest Service is committed to working with the Department of 
Homeland Security (DHS) and the Department of Interior (DOB as 
reflected in the Memorandum of Understanding (MOU) signed in March of 
2006 by the three Secretaries. As a result of the MOU, the Forest 
Service is actively engaged with the tri-agency Environmental and 
Cultural Stewardship Training Task Force. The Task Force recently 
began work on the development of a new web-based training course to 
provide Border Patrol agents with environmental and cultural resource 
training formatted to meet Border Patrol operational constraints. Task 
Force members also routinely share information with each other about 
training occurring at the local level in order to leverage ongoing 
efforts. 

The report also recommended that the Secretaries of DHS, DOI, and USDA 
take steps to help Border Patrol expedite access to portions of 
federal lands by more quickly initiating required assessments. The 
Forest Service has and will continue to work with DHS to facilitate 
access to National Forest System lands. This cooperation extends from 
completing assessments to actual operations. For example, the Coronado 
National Forest receives funding from DHS for forest staff and 
equipment to maintain unpaved roads needed for Border Patrol 
activities. 

The Forest Service places great value on our relationship with DHS and 
DOI and is committed to looking for ways to strengthen our continuing 
alliance with them now and into the future. If you have any questions, 
please contact Donna M. Carmical, Chief Financial Officer, at 202-205-

Footnotes: 

[1] The borderlands region encompasses the area extending from the 
United States-Mexico border north to 100 miles. 

[2] In some cases, the patrol agent-in-charge designated the assistant 
patrol agent-in-charge or the field operations supervisor as the 
respondent to our structured interview because the patrol agent-in- 
charge was relatively new and therefore less familiar with how land 
management laws may affect Border Patrol operations. 

[3] 8 U.S.C. §§ 1101-1537. 

[4] Depending on size and location, individual federal borderlands may 
fall within one or more stations' area of patrol responsibility and 
across one or two sectors. 

[5] Targeted enforcement efforts in other Border Patrol sectors in 
previous years caused a shift in illegal cross-border activity to the 
Tucson Sector, according to Border Patrol officials. The Congressional 
Research Service has stated that the overall borderwide decline in 
apprehensions is likely due to a combination of decreased 
opportunities for work in the United States and increased enforcement 
at the border. Congressional Research Service, Border Security: The 
Role of the U.S. Border Patrol, RL32562 (Washington, D.C., 2010). 

[6] Border Patrol classifies an area's border security status as one 
of five levels: An area is considered "controlled" when Border Patrol 
can deter or detect entries at the border, and continual, real-time 
surveillance and enforcement activities result in a high probability 
of immediate apprehension at the border. An area is considered 
"managed" when sufficient Border Patrol resources are available to 
deter or detect entries in time to apprehend, although not always at 
the immediate border, and sufficient resources exist to fully 
implement the sector's border control strategy and tactics. An area is 
considered "remote/low activity" when the sector has not defined 
issues affecting Border Patrol and has not developed a meaningful 
Border Patrol strategy. An area is considered "low-level monitored" 
when detection or apprehension is inhibited by a lack of resources or 
infrastructure. An area is considered "monitored" when the probability 
of detection is high, but the ability to respond is limited because 
the terrain is remote and rugged, Border Patrol has limited resources, 
or both. 

[7] Border Patrol supports the initiative by detecting and preventing 
the illegal entry of aliens into the United States between designated 
ports of entry. 

[8] Also as part of this initiative, DHS began development of a 
comprehensive border protection system using cameras, known as SBInet, 
and tactical infrastructure, which includes border fencing, roads, and 
lighting. According to the Executive Director of DHS's Secure Border 
Initiative, the continued and repeated delays in developing SBInet 
raised fundamental questions about its viability and availability to 
meet the need for technology along the southwestern border. 
Consequently, the Secretary of Homeland Security ordered a freeze on 
all SBInet funding until a departmentwide reassessment is completed.

[10] Third parties, including Border Patrol, generally cannot 
undertake any road activities, except for public access, without a 
permit from a land management agency, and that permit would need to be 
consistent with the applicable land and resource management plans, 
which govern road construction, access, maintenance, and 
decommissioning.

[12] For a project to be approved using a categorical exclusion, the 
agency must determine whether any extraordinary circumstances exist in 
which a normally excluded action or project may have a significant 
effect. Border Patrol has numerous categorical exclusions in place, 
including, for example, installation and operation of security 
equipment at existing facilities to screen for or detect dangerous or 
illegal individuals and routine monitoring and surveillance 
activities, such as patrols, investigations, and intelligence 
gathering.

[16] While a few of the wilderness areas along the United States-
Mexico border were designated in the 1964 act, most were established 
later. In one case, the law establishing the area specifically 
addressed border security: the Arizona Desert Wilderness Act of 1990 
established the Cabeza Prieta Wilderness Area in the Cabeza Prieta 
National Wildlife Refuge and stated that the land's designation as 
wilderness must not preclude or otherwise affect border operations in 
accordance with any existing interagency agreement. 

[17] The National Park Service does not have general regulations 
governing administration of wilderness areas in national parks. 
Instead, each Park Service unit administers its wilderness areas in 
accordance with a wilderness management plan that it develops and the 
National Park Service's Wilderness Management Policy. Under the 
policy, administrative use of motorized equipment or mechanical 
transport is authorized only (1) in emergency situations--for example, 
homeland security and law enforcement--involving the health or safety 
of persons actually within the area or (2) if the unit's 
superintendent determines it to be the minimum requirement needed by 
management to achieve the purposes of the wilderness area. Determining 
the minimum requirement is a two-step process that first determines 
whether the proposed management action is appropriate or necessary for 
administration of the area as wilderness and does not cause a 
significant impact to wilderness resources and character and then 
determines the techniques and types of equipment needed to ensure that 
impacts on wilderness resources and character are minimized. 

[18] Pub. L. No. 93-205 (1973), codified as amended at 16 U.S.C. §§ 
1531-1544. 

[19] The action agency, in this case the Border Patrol, determines 
whether and how to proceed with its proposed action in light of the 
biological opinion. Nevertheless, reviewing courts traditionally 
afford the biological opinion substantial deference, and action 
agencies must give great weight to the biological opinion before 
deciding on a proposed action.

U.S. Department of Agriculture, Memorandum of Understanding on 
Regarding Cooperative National Security and Counterterrorism Efforts 
on Federal Lands along the United States' Border (Washington, D.C., 
March 2006). 

[21] In addition, in developing the plan, officials from both agencies 
acknowledged that technological resources are needed in rough terrain 
where it is impractical to create roads. Moreover, technological 
resources help give agents more time to respond by helicopter, 
horseback, or all-terrain vehicle to apprehend suspected undocumented 
aliens. The plan therefore allows for the placement of 14 remote video 
surveillance systems throughout the forest, numerous underground 
sensors, and unmanned aerial vehicles, among other tools. 

[22] Mobile surveillance systems perform a 180-degree sweep every 10 
seconds. 

[23] The federal land management agency does not always approve access 
for the entire road needed to reach requested areas; for example, the 
agency may in some cases perform environmental and historic property 
assessments only at the location where Border Patrol wants to put the 
surveillance equipment. 

[24] The one outstanding issue, one agent-in-charge explained, is for 
the land management agencies to more clearly define all roads that 
Border Patrol can maintain. According to the Coronado National Forest 
road manager, special use permits will soon be issued for the roads 
Border Patrol needs, and the roads will be mapped and identified for 
Border Patrol. 

[25] As part of the contract for tactical infrastructure maintenance 
and repair--a fiscal year 2011 contract for the maintenance and repair 
of vehicle and pedestrian fences, among other things, along the 
southwestern border--Border Patrol is developing a list of what roads 
it needs for access to fencing. In developing this list, Border Patrol 
officials told us they will identify what roads have had environmental 
and historic property assessments. For those roads that have not been 
assessed, Border Patrol plans to prepare a programmatic environmental 
impact statement under the National Environmental Policy Act. Border 
Patrol headquarters officials told us this document will include many--
but not all--roads in the borderlands region. According to Border 
Patrol headquarters officials, they met with all land managers of land 
units along the border in July 2011 to discuss with them what roads 
will have environmental and historic property assessments. 

[26] According to an equipment manufacturer, remote video surveillance 
systems consist of integrated thermal imaging video surveillance and 
provide long-range (12-mile) video surveillance day or night in all 
weather conditions. Ground-based radar is used to detect undocumented 
aliens over an extended range and is linked with remote video 
surveillance systems for use in hard-to-reach areas. Ground-based 
radar provides early warning and sends both visual and audible alarms 
to a command center. Additionally, it collects data on the number of 
undocumented aliens, direction of movement, and speed of movement, 
which aids apprehension efforts. 

[27] Forest Service regulations authorize the Chief of the Forest 
Service to prescribe conditions under which motorized equipment, 
installations, and structures may be used in emergencies involving the 
health and safety of persons. 

[28] The 2006 memorandum of understanding states that Border Patrol 
may operate motor vehicles at any time on existing public and 
administrative roads or trails and in areas previously designated by 
the land management agency for off-road vehicle use, provided that 
such use is consistent with presently authorized public or 
administrative use (emphasis added). 

[29] Second-level Border Patrol supervisors are field operations 
supervisors. At least one such supervisor is on duty during each shift. 

[30] This national process, known as the operational requirements-
based budgeting process and occurring twice each year, was developed 
to help Border Patrol determine how and where to allocate additional 
agents, technology, and infrastructure. 

[31] According to the Bureau of Land Management state program director 
for California, the bureau determined on a national level that 
changing a route or adding a route is allowed under land resource 
management plans; environmental and historic property assessments 
would still be needed, along with consultations required by the 
Endangered Species Act, but such access could be granted. 

[32] The 2006 memorandum of understanding directs the parties to 
cooperate with each other to identify methods, routes, and locations 
for Border Patrol operations that will minimize impacts to natural, 
cultural, and wilderness resources resulting from Border Patrol 
operations while facilitating needed Border Patrol access. 

[33] Organ Pipe and Cabeza Prieta land managers told us they are 
hoping that mapping off-road vehicle incursions will help them work 
with Border Patrol to identify approaches for apprehending 
undocumented aliens as close to the border as possible--a strategy 
outlined in the 2006 memorandum of understanding--thus averting the 
need to travel as much off road in these wilderness areas. 

[34] Administered by the Bureau of Land Management's Arizona state 
office to mitigate the effects of cross-border illegal activity on 
Arizona borderlands, the Southern Arizona Project began in 2003. In 
fiscal year 2009, Southern Arizona Project funding--which comes from 
the Bureau of Land Management's annual base appropriations for 
resource protection--totaled approximately $1.14 million. 

[35] The Secretary has invoked this waiver authority five times since 
passage of the act. 

[36] Notwithstanding the total mileage requirement of 700 miles, the 
Secretary is not required to install fencing, physical barriers, 
roads, lighting, cameras, or sensors in a particular location if the 
Secretary determines that the use or placement of such resources is 
not the most appropriate means to achieve and maintain operational 
control over the international border at a given location. 

[37] DHS also used biological resource plans, which it completed in 
lieu of section 7 consultations, and monitoring reports on specific 
fence segments to identify mitigation measures. 

[38] The 2006 memorandum of understanding states that Interior and the 
Forest Service will provide Border Patrol agents with environmental 
and cultural awareness training formatted to meet Border Patrol's 
operational constraints. 

[39] This training came in addition to the basic environmental and 
cultural resource awareness training that Border Patrol provides to 
all new agents.

Development Efforts in the Federal Government, [hyperlink,

2004). 

[41] For example, according to the Department of the Interior, about 
50,000 acres of the 90,000-acre Lower Rio Grande Valley National 
Wildlife Refuge--one of three refuges in the South Texas Complex--are 
closed to the public and have been since the refuge was established in 
1979. Disturbances to wildlife, impacts to animal travel corridors, 
and the safety of staff and visitors, as well as the dangers 
associated with illegal border activity, are among the reasons for 
keeping the refuge tracts on the river closed. 

[42] In some cases, the patrol agent-in-charge designated the 
assistant patrol agent-in-charge or the field operations supervisor as 
the respondent to our structured interview because the patrol agent-in-
charge was relatively new and, thus, less familiar with how land 
management laws may effect Border Patrol operations.
