Highlights of GAO-12-73, a report to congressional requesters. 

Why GAO Did This Study: 

Wildland fires can result from both natural and human causes. Human-
caused wildland fires are of particular concern in Arizona-—especially 
within 100 miles of the U.S.-Mexico border because this is a primary 
area of entry for illegal border crossers and GAO has previously 
reported that illegal border crossers have been suspected of igniting 
wildland fires. Over half of the land in the Arizona border region is 
managed by the federal government-—primarily by the Department of 
Agriculture’s Forest Service and four agencies within the Department 
of the Interior. These agencies collaborate with state, tribal, and 
local entities to respond to wildland fires. GAO was asked to examine, 
for the region, the (1) number, cause, size, and location of wildland 
fires from 2006 through 2010; (2) economic and environmental effects 
of human-caused wildland fires burning 10 or more acres; (3) extent to 
which illegal border crossers were the ignition source of wildland 
fires on federal lands; and (4) ways in which the presence of illegal 
border crossers has affected fire suppression activities. GAO reviewed 
interagency policies and procedures; analyzed wildland fire data; and 
interviewed federal, tribal, state, and local officials, as well as 
private citizens. 

What GAO Found: 

From 2006 through 2010, at least 2,467 wildland fires occurred in the 
Arizona border region. Of this number, 2,126, or about 86 percent, 
were caused by human activity. The majority of these fires—-1,364—-
burned less than 1 acre each. About 63 percent or 1,553 of the 2,467 
fires were ignited on federally managed land or tribal land. 

Human-caused wildland fires that burned 10 or more acres had a number 
of economic and environmental impacts on the Arizona border region, 
but these impacts cannot be fully quantified because comprehensive 
data are not available. Specifically, these fires resulted in (1) over 
$35 million in fire suppression costs by federal and state agencies, 
(2) destruction of property, (3) impacts on ranching operations, and 
(4) impacts on tourism. Similarly, these fires had several 
environmental impacts, such as the expansion of nonnative plant 
species, degraded endangered species habitat, and soil erosion. 
However, the full economic and environmental impacts cannot be 
determined because complete information about these impacts is not 
available. 

The total number of fires ignited by illegal border crossers on 
federal lands in the Arizona border region is not fully known, in part 
because federal land management agencies have not conducted 
investigations of all human-caused wildland fires that occurred on 
these lands, as called for by agency policy, and the agencies do not 
have a strategy for selecting fires they do investigate. Of the 422 
human-caused wildland fires that occurred on Forest Service, Interior, 
or tribal lands and burned at least 1 acre from 2006 through 2010, 
only 77 were investigated. According to land management agency 
officials, the lack of trained fire investigators was the primary 
reason for the limited number of investigations. Of the investigations 
conducted, 30 identified illegal border crossers as a suspected source 
of ignition. Agency policy notes that identifying trends in fire 
causes is critical to the success of fire prevention programs, but 
without better data on the specific ignition sources of human-caused 
wildland fires in the region, the agencies are hampered in their 
ability to target their efforts to prevent future wildland fires. 

The presence of illegal border crossers has complicated fire 
suppression activities in the Arizona border region. According to 
agency officials, the presence of illegal border crossers has 
increased concerns about firefighter safety and, in some instances, 
has required firefighters to change or limit the tactics they use in 
suppressing fires. For example, the presence of illegal border 
crossers has limited firefighting activities at night and complicated 
the use of aerial firefighting methods. The agencies have taken some 
steps to mitigate the risks to firefighters by, for example, using law 
enforcement to provide security. However, none of the agencies have 
developed or implemented a risk-based approach for addressing these 
challenges. Consequently, law enforcement resources are routinely 
dispatched to all fires regardless of the risk, which may prevent the 
agencies from using their limited resources most efficiently. 
Moreover, while the Forest Service has developed a formal policy for 
addressing the risks to firefighters in the region, the other agencies 
have neither formally adopted this policy nor developed their own. 

What GAO Recommends: 

GAO recommends, among other things, that the agencies develop 
strategies for selecting fires to investigate and establish a risk-
based approach for utilizing law enforcement resources. In their 
comments on a draft of this report, the Forest Service and the 
Department of the Interior generally agreed with these recommendations.

Congressional Requesters: 

A natural part of many ecosystems, wildland fires can have devastating 
effects on communities, damage sensitive ecosystems, and be costly to 
suppress. Wildland fires may be ignited by lightning or as a result of 
human activities, such as improperly extinguished campfires, sparks 
from equipment and vehicles, or recreational shooting. Fires triggered 
by natural causes are inevitable and play an important ecological role 
on many landscapes, but human-caused wildland fires can damage areas 
that might not otherwise experience fire or that might burn with less 
frequency or severity.[Footnote 1] The recent Horseshoe Two and 
Monument fires in southern Arizona provide vivid examples of the 
devastation that can result from human-caused wildland fires. The 
Horseshoe Two Fire burned nearly 223,000 acres in May and June 2011, 
mostly on the Coronado National Forest, and cost millions to suppress. 
Similarly, according to preliminary estimates from the agencies, the 
Monument Fire burned more than 30,000 acres in the Huachuca Mountains 
in June and July 2011, destroyed more than 60 homes, and forced 
thousands of residents living near Sierra Vista, Arizona, to evacuate. 
[Footnote 2] 

Human-caused wildland fires are of particular concern in Arizona along 
the Mexico border because southeast Arizona is a primary entry point 
for illegal border crossers on the U.S. southwestern border. As we 
reported in December 2010, illegal border crossers have been suspected 
of starting wildland fires either by accident--for example, from 
cooking fires that escape--or on purpose--for example, to divert law 
enforcement resources away from a particular area.[Footnote 3] In this 
context, you asked us to examine wildland fires that occurred in 
Arizona within 100 miles of the U.S.-Mexico border during the previous 
5 years.[Footnote 4] For such wildland fires, this report examines (1) 
their number, cause, size, and location; (2) the economic and 
environmental effects of human-caused wildland fires that burned 10 or 
more acres; (3) the extent to which federal agencies determined that 
illegal border crossers were the ignition source of wildland fires on 
federal and tribal lands; and (4) ways in which the presence of 
illegal border crossers has affected fire suppression activities in 
this area. 

To determine the extent of wildland fire occurrence in the Arizona 
border region, we collected federal and state wildland fire occurrence 
data from databases at the National Interagency Fire Center (NIFC) 
[Footnote 5] for fires that occurred within Arizona during calendar 
years 2006 through 2010.[Footnote 6] From these data, we identified 
those wildland fires that occurred within 100 miles of the Arizona-
Mexico border. For these fires, we then analyzed the data to identify 
the acreage burned and general cause--human or natural--cited for 
ignition. We assessed the reliability of the data we used by reviewing 
information about the underlying database systems and discussing the 
data with agency officials responsible for managing these databases, 
and determined that the data were sufficiently reliable for the 
purposes of presenting acreage burned and general cause of wildland 
fires. We also obtained information from the Department of Defense 
regarding wildland fire incidents on its lands in the region--which is 
not included in NIFC's data--and included these data in our overall 
analysis. We identified those human-caused wildland fires that burned 
10 or more acres (referred to as significant fires for the purposes of 
this report) and obtained data on suppression cost obligations for 
those fires as well as available documentation of economic and 
environmental effects. In addition, we visited the region and 
discussed with federal and nonfederal fire suppression and law 
enforcement officials, as well as private industry representatives and 
private citizens in the ranching community, their experiences with 
wildland fire occurrence and suppression activities, as well as the 
economic and environmental damage as a result of human-caused wildland 
fires. To assess the extent to which federal agencies determined that 
illegal border crossers were the ignition source of these fires, we 
reviewed agency documents to identify criteria for conducting 
investigations into the ignition source of human-caused wildland 
fires. We also collected and analyzed fire investigation reports to 
evaluate the extent to which fire investigations were conducted for 
human-caused wildland fires that burned 1 or more acres and, for those 
fires for which investigations were conducted, the extent to which 
officials identified illegal border crossers as the source of 
ignition. Additionally, we reviewed fire incident reports created by 
fire response personnel to identify the extent to which they cited 
illegal border crossers as a potential source of ignition. To 
determine the ways in which the presence of illegal border crossers 
has affected fire suppression in the Arizona border region, we 
reviewed national and regional land management wildland fire guidance 
to identify any practices unique to regional land management units 
developed in response to illegal cross-border activity. During our 
site visits, we also discussed with federal and nonfederal officials 
their experiences fighting wildland fires in the region. 

We conducted this performance audit from December 2010 to November 
2011 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 Arizona-Mexico border extends about 370 miles, accounting for 
almost 20 percent of the 2,000-mile U.S.-Mexico border. About 51 
percent of the land in the Arizona border region is managed by the 
federal government, primarily by the Forest Service within the 
Department of Agriculture, four agencies within the Department of the 
Interior--the Bureau of Indian Affairs (BIA), Bureau of Land 
Management (BLM), Fish and Wildlife Service (FWS), and National Park 
Service (NPS)--and the Department of Defense (DOD).[Footnote 7] The 
remainder of the land is local or private (21 percent), state-managed 
(16 percent), or tribal (12 percent). Figure 1 shows the areas managed 
by these various entities.

Each federal agency that manages land within the border region has a 
distinct mission and set of responsibilities, which may include 
managing the land for multiple uses, such as recreation; conserving 
natural and historic resources; conserving and enhancing fish, 
wildlife, plants, and their habitats; and providing rangeland for 
grazing. Federal agency responsibilities for land units in the Arizona 
border region include the following: 

* The Forest Service manages the Coronado National Forest, which 
covers almost 1.8 million acres of southeastern Arizona and New Mexico 
and ranges in elevations from 3,000 feet to over 10,000 feet. In 
addition to the preservation of natural resources, the forest is used 
for recreational purposes and ranchers use some of the forest for 
grazing. In October 2010, we reported that more illegal border 
crossers migrate through the Coronado National Forest than any other 
federal land unit along the southwestern border.[Footnote 8] The 
Forest Service has reported that the number of illegal border crossers 
traveling in the area threatens natural resources and creates a 
dangerous environment for the public and for Forest Service 
employees.[Footnote 9] 

* BIA provides services to several Indian tribes, including the Tohono 
O'odham Nation, Colorado River Nation, Fort Yuma-Quechan Nation, Ak- 
Chin Tribal Community, and Gila River Indian Community within the 
Arizona border region. The Tohono O'odham Nation, the largest Indian 
tribe within the Arizona border region, covers about 2.9 million 
acres, an area approximately the size of Connecticut. Tohono O'odham 
officials have previously reported that illegal border crossers cause 
significant damage to their lands.[Footnote 10] 

* BLM manages numerous public lands in the border region, including 
the nearly half-million-acre Sonoran Desert National Monument, San 
Pedro National Conservation Area, and Ironwood Forest National 
Monument. BLM lands are used for multiple purposes, including 
recreation, grazing, mining, and wildlife habitat. In our November 
2010 report, we reported that BLM officials posted warning signs at 11 
entrance locations of the Sonoran Desert National Monument to warn the 
public against travel on portions of the monument because of potential 
encounters with illegal border crossers.[Footnote 11] 

* FWS works to preserve and enhance fish, wildlife, plants, and their 
habitats in wildlife refuges in the region, including the Buenos 
Aires, Cabeza Prieta, Imperial, and Kofa National Wildlife Refuges. In 
December 2010, we reported that the Refuge Manager of Buenos Aires 
National Wildlife Refuge testified before Congress that illegal border 
crossers have disturbed wildlife and created more than 1,300 miles of 
illegal trails, causing the loss of vegetation and severe erosion. 
[Footnote 12] In addition, a portion of the refuge adjacent to the 
border has been closed to the public due to safety concerns caused by 
illegal border crossers. 

* NPS is responsible for conserving the scenery, natural and 
historical objects, and wildlife of the national park system, which 
includes Coronado National Memorial, Organ Pipe Cactus National 
Monument, and Saguaro National Park in the Arizona border region. As 
was the case with the Buenos Aires National Wildlife Refuge, the Organ 
Pipe Cactus National Monument has previously been closed to the public 
because of the safety concerns associated with illegal border 
crossers. Officials at other sites, such as the Fort Bowie National 
Historic Site, have reported that the cultural and historical 
integrity of the site has been compromised by illegal border crossers 
because of the waste they have left in the area--including clothing, 
cans, water jugs, plastic bags, and human waste. 

* DOD manages a number of installations and facilities used for 
testing and training its forces in the region, including Fort 
Huachuca, the Yuma Proving Grounds, the Barry M. Goldwater Range, and 
Davis-Monthan Air Force Base. DOD officials told us that training 
missions at the Barry M. Goldwater Range have been delayed or altered 
due to the presence of illegal border crossers. 

Additionally, agents of the U.S. Border Patrol--an office within the 
Department of Homeland Security (DHS)--patrol federal and nonfederal 
lands near the border to find and apprehend persons who have illegally 
crossed the U.S. border. Border Patrol is responsible for controlling 
and guarding the boundaries and borders of the United States against 
the illegal entry of people who are not citizens or 
nationals.[Footnote 13] Border patrol agents 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 on federal lands and other areas up 
to 100 miles from the border. 

Each of the federal land management agencies also has responsibility 
to respond to wildland fires on federal lands, while the Arizona State 
Forestry Division and other entities--including tribal and local fire 
departments--have primary responsibility for responding to wildland 
fires on state, local, and private lands. When a wildland fire starts 
on federal land, federal policy directs federal agencies to consider 
land management objectives--identified by land and fire management 
plans developed by each land management unit--and the structures and 
resources at risk when determining whether and how to suppress it. 
Historically, the Forest Service and the Interior agencies attempted 
to suppress all wildland fires quickly because of their potentially 
damaging effects on local economies and natural environments; in 
recent decades, however, the agencies fundamentally reassessed their 
understanding of naturally occurring wildland fire's role on the 
landscape, and they began to see more benefits from these wildland 
fires. For instance, fire can limit the spread of insects and 
diseases, reduce brush and weeds, and return the nutrients to the 
soil, where they help produce a new generation of plants. For ranchers 
whose cattle are dependent on the new generation of plants, fire can 
burn unwanted brush and allow grasses to flourish in future years. If 
agencies determine that a naturally ignited wildland fire can promote 
land management objectives, they may use less aggressive fire 
suppression strategies that not only can reduce fire suppression costs 
in some cases but can also be safer for firefighters by reducing their 
exposure to unnecessary risks. In contrast, interagency policy calls 
for these agencies to initiate suppression activities immediately for 
all human-caused wildland fires. 

Fire suppression efforts are mobilized through an interagency incident 
management system, which depends on the close cooperation and 
coordination of federal, state, tribal, and local fire protection 
entities. Fighting wildland fires--which can burn across federal, 
state, and local jurisdictions--can require investments of personnel, 
aircraft, equipment, and supplies and can result in substantial fire 
suppression expenditures. 

To document fire occurrence, fire personnel prepare a fire incident 
report, and the information from these reports populates the agencies' 
fire data management systems. The information collected in these 
reports includes basic data such as date the fire started, location, 
general cause (natural or human), number of acres burned, and the date 
the fire was extinguished. Firefighters can also include narrative 
information in these reports, such as information about suppression 
activities or fire cause. 

Number, Cause, Size, and Location of Wildland Fires in the Arizona 
Border Region: 

From 2006 through 2010, at least 2,467 wildland fires occurred in the 
Arizona border region. Most of these fires were caused by human 
activity, burned less than 1 acre each, and were ignited on federal or 
tribal land. Federal and state agencies determined that 2,126 of these 
fires, or about 86 percent, were caused by human activities (see 
figure 2). This percentage is consistent with the national average for 
wildland fires caused by human activities; according to NIFC data, 
about 87 percent of all wildland fires that occurred nationally from 
2006 through 2010 were caused by human activities.

[End of figure] 

Most of the human-caused wildland fires--1,364, or 64 percent--burned 
less than 1 acre of land each; 508 fires burned from 1 to 10 acres 
each; and 241 fires were significant, burning 10 or more acres each. 
[Footnote 14] These 241 significant human-caused wildland fires burned 
a total of more than 123,000 acres, which accounts for about 99 
percent of all acres burned during this time by human-caused wildland 
fire in the region; the largest of these wildland fires--the 2009 
Elkhorn Fire--burned more than 23,000 acres. See figure 3 for the 
location of significant human-caused wildland fires during this 
period. The 2011 Horseshoe Two and Monument fires, which occurred 
after the period for which we analyzed data, were much larger than any 
of the fires that occurred from 2006 through 2010. Based on 
preliminary information, federal agencies reported that these two 
fires burned more than 250,000 acres--more than twice the cumulative 
total of all significant human-caused wildland fires in the area 
during the previous 5 years.

Note: Significant human-caused wildland fires are those that burned 10 
or more acres. 

[End of figure] 

Of the 341 fires that federal and state agencies determined to be 
natural ignitions--caused by lightning--156, or 46 percent, burned 
less than 1 acre each; 87 burned from 1 to 10 acres each; and 98 fires 
were significant, burning 10 acres or more. Naturally ignited wildland 
fires burned nearly 74,000 acres, although agency officials explained 
that some of these fires were allowed to burn (i.e., they were not 
suppressed by firefighters) for ecological and resource management 
purposes. 

Of the 2,467 wildland fires included in our review, the majority of 
the fires--1,553, or 63 percent--were ignited on federal or tribal 
lands. The remaining fires were ignited on state, local, or private 
lands (see table 1).

The Economic and Environmental Effects of Significant Wildland Fires 
in the Arizona Border Region Are Not Fully Known: 

Significant human-caused wildland fires in the Arizona border region 
have resulted in a number of economic and environmental impacts. 
Economic impacts include millions of dollars in fire suppression 
costs, destruction of homes and ranching operations, and impacts on 
regional tourism. Environmental impacts include damaged habitat for 
endangered species and expansion of nonnative plants in the region. 
However, it is not possible to fully quantify the effects of these 
fires on the region's economy or environment because complete 
information needed for such analyses is not available. 

Significant Human-Caused Wildland Fires Have Resulted in Various 
Economic Impacts, but the Full Impact on the Region Is Unknown: 

Significant human-caused wildland fires in the Arizona border region 
have had various economic impacts. These impacts include (1) the costs 
associated with suppressing wildland fires; (2) the destruction of 
property, including homes and ranching infrastructure; and (3) impacts 
on tourism. While we were able to identify specific examples of these 
fires' impacts on the area's economy, we could not determine the 
overall impact of these fires on local economies because complete 
information is not available that would allow such an analysis. 

Fire suppression costs. In response to significant human-caused 
wildland fires that occurred from 2006 through 2010 in the Arizona 
border region, federal land management agencies obligated more than 
$33 million for suppression activities,[Footnote 15] and the state of 
Arizona obligated almost $2 million.[Footnote 16] Forest Service 
suppression obligations accounted for more than $26 million, or about 
80 percent of all federal obligations to suppress these fires. The 
amount of funding obligated for individual significant human-caused 
wildland fires varied widely. For a majority of these fires, federal 
and state agencies obligated less than $25,000 per fire. Conversely, 
for 23 fires, or about 10 percent, agencies obligated more than 
$250,000 each, with the 2010 Horseshoe Fire, which burned more than 
3,400 acres on the Coronado National Forest, accounting for more than 
$10 million--nearly a third of all federal obligations for significant 
human-caused wildland fires in the region from 2006 through 2010. 
[Footnote 17] Characteristics affecting suppression costs include fire 
size; fuel types; fire intensity; physical terrain; proximity to the 
nearest community; total value of structures close to the fire; and 
special management considerations, such as whether the fire was 
burning in a wilderness or other designated area. It is also important 
to note that suppression costs may represent only a fraction of the 
total true costs for these fires. For example, one study that reviewed 
six fires of at least 40,000 acres in the western United States found 
that, in these cases, other costs associated with the fires, such as 
damage to properties and ecosystems and loss of economic activities, 
were generally several times higher than suppression costs.[Footnote 
18] 

Destruction of property and injuries to homeowners. Significant human- 
caused wildland fires in the region have destroyed houses and other 
property and injured residents. For example, according to the Forest 
Service, the 2009 Canelo Fire, which burned over 4,000 acres, 
destroyed at least three residences, several outbuildings, and 
numerous vehicles. In addition, one homeowner was seriously burned 
during that wildland fire and required hospitalization. Similarly, the 
2011 Monument Fire destroyed more than 60 homes, according to 
preliminary agency estimates. 

Impacts on ranching operations. Significant human-caused wildland 
fires have also affected ranching operations in the region. Such fires 
have damaged grazing allotments and related improvements[Footnote 19]--
such as fences, water tanks, and pipelines--located on federal lands 
and used by private ranchers.[Footnote 20] The Forest Service reported 
obligating more than $100,000 in long-term restoration and 
rehabilitation funds to repair fences, protect watersheds, and clean 
water tanks on federal grazing allotments damaged by four significant 
human-caused wildland fires.[Footnote 21] Additionally, from 2006 
through 2010, Forest Service officials told us they provided about 
$56,000 in fencing and pipeline materials to repair damage on 15 
allotments burned by significant human-caused wildland fires.[Footnote 
22] Forest Service officials told us the agency does not always have 
supplies to provide, however, and generally does not provide labor to 
repair damage to allotments. As a result, local ranchers can incur 
costs for labor and materials to repair damage to allotments. One 
rancher whose federal grazing allotment was burned during the 2009 Hog 
Fire told us that, although the Forest Service has offered to provide 
the materials to replace fencing that was burned during the fire, in 
order to use the allotment again, he would have to spend about 
$250,000 for labor costs to build the new fence to Forest Service 
specifications. 

Additionally, federal agency officials and private ranchers told us 
that, in some circumstances, ranchers must move their cattle from 
federal grazing allotments because agencies have determined that the 
damage to the vegetation on which the cattle feed requires time to 
recover--typically 1 to 3 years, according to federal officials. As a 
result of significant human-caused wildland fires from 2006 through 
2010, Forest Service officials reported that some cattle were removed 
from 20 allotments, and grazing schedules were altered for at least an 
additional 5, to allow vegetation to recover. A Forest Service 
official told us that the grazing capacity for 17 of these allotments 
has been reduced by 25 percent because of wildland fires. 
Additionally, one allotment that covers more than 50,000 acres was 
affected by 13 significant human-caused wildland fires from 2006 
through 2010, according to federal agency officials, resulting in the 
repeated removal of cattle from the allotment and an altering of 
grazing schedules. According to industry representatives and private 
ranchers, moving cattle from an allotment negatively affects ranchers 
because they must either find alternative locations to graze their 
cattle or purchase additional feed. Further, private ranchers stated 
that the value of their cattle can potentially decrease as a result of 
the stresses to the animals associated with the fires and transfers 
between allotments. 

Impacts on tourism. Significant human-caused wildland fires can also 
affect tourism. According to a representative from the Cochise College 
Center for Economic Research,[Footnote 23] as well as local residents 
that we spoke with, fires can affect tourism because access to trails, 
campgrounds, and roads can be temporarily restricted and, more 
broadly, fires can diminish the appeal of the region for tourists. For 
example, local residents told us that hospitality businesses in 
Portal, Arizona, have been particularly vulnerable to the economic 
impacts of wildland fires because these businesses are dependent on 
visitors to the Coronado National Forest. If access to the forest is 
restricted, as it was in 2010 as a result of the Horseshoe Fire, these 
residents told us it can have a direct impact on local businesses. 

While the preceding examples provide some understanding of the nature 
of the economic impacts of significant human-caused wildland fires in 
the Arizona border region, we could not quantify the overall effect of 
these fires on the region because comprehensive and consistent data 
are not available. For example, we found no data that would allow us 
to determine the extent to which the closures of national forests and 
other public lands have affected tourism in the region, and we 
likewise did not find data that would allow us to identify the 
cumulative impact of significant human-caused wildland fires on 
tourist-related businesses.[Footnote 24] Moreover, the economic 
researcher from the Cochise College Center for Economic Research noted 
that it is difficult to assess the overall economic impact of such 
incidents because the Arizona border region is rich in ecotourism 
resources. As a result, it is possible that visitors who could not 
visit a specific location may have still visited the region, simply 
choosing to visit other local areas. Additionally, as noted in one 
study we reviewed, identifying the real cost of wildland fires on the 
economy is difficult because few data sources are consistent from fire 
to fire, and many lack any data at all.[Footnote 25] According to this 
study, the effects resulting from individual fires are unique to each 
fire and cannot be generally extrapolated to other fires. The 
representative we spoke to from the Cochise College Center for 
Economic Research also noted that the economic effects of wildland 
fire can be mixed and, therefore, difficult to delineate. For example, 
while wildland fires can provide a temporary boost to several 
industries in the region--such as construction and retail and 
restaurant sales--that boost could be offset by increases in home 
insurance premiums in the area and lost revenue and wages from other 
displaced businesses or workers. 

Significant Human-Caused Wildland Fires Have Damaged the Environment, 
but the Full Extent Is Unknown: 

Significant human-caused wildland fires have damaged the natural 
environment in the Arizona border region, but the comprehensive 
effects are unknown, in part because--as with the economic effects of 
wildland fires--complete information is not available on the 
environmental effects of wildland fire. According to our analysis of 
federal emergency treatment plans and discussions with federal agency 
and tribal officials, the most common environmental effects of 
wildland fire in the region are expansion of nonnative plant species, 
degraded endangered species habitat, and soil erosion. These effects 
may result from both significant human-caused wildland fires and other 
fires. The following are descriptions of these environmental effects 
and examples of the effects that have been noted from individual 
instances of significant human-caused wildland fires in the region. 
[Footnote 26] 

Expansion of nonnative plant species. Plant species that are not 
native to southern Arizona, such as buffelgrass and tamarisk--commonly 
known as salt cedar--can regenerate more quickly following wildland 
fires than native species and may displace such species from their 
traditional ranges. The expansion of these species can also alter 
natural fire patterns by making areas susceptible to burning with more 
severity or frequency than they traditionally would. For example, the 
2009 Powers Fire, a human-caused wildland fire that burned 260 acres, 
destroyed native vegetation such as cottonwood and willows along the 
Gila River. As a result, BLM predicts that nonnative salt cedar will 
increase in density along the river. BLM noted in its postwildfire 
environmental damage assessment that the increased density of salt 
cedar will degrade the habitat because salt cedar actively resprouts 
after wildland fires and can create enough fuel to burn again within 5 
years. 

Damage to endangered species habitat. Southern Arizona is home to a 
number of federally listed threatened and endangered plant and animal 
species.[Footnote 27] Some wildland fires can damage the habitats of 
these species and, in turn, threaten their continued existence. For 
example, the 2007 San Luis Fire--a human-caused wildland fire that 
burned 68 acres of mostly BLM land--damaged riparian areas that are 
habitat for two bird species federally listed as endangered, the 
Southwestern Willow Flycatcher and the Yuma Clapper Rail, as well as 
another that is a candidate for listing, the Yellow-Billed Cuckoo. 
[Footnote 28] 

Increased soil erosion. Soil erosion can also result from wildland 
fires in the region. During the seasonal "monsoon rains" that Arizona 
typically experiences in the summer, areas where wildland fires have 
burned away the vegetation holding soil together may experience 
increased runoff and mudslides that can damage natural habitats, 
watersheds, roads, and trails. For example, an official with the 
Tohono O'odham Nation told us that the nation is concerned about the 
impact the human-caused 2009 Elkhorn Fire will have on the Kearney's 
Blue Star, which is an endangered plant species. The fire itself did 
not damage the plant's population, but as a result of the fire, water 
runoff and soil erosion are expected to increase, which would threaten 
the plant's population at lower elevations. 

To mitigate such impacts on federal lands in the region, from 2006 
through 2010, federal agencies obligated nearly $1.9 million through 
the Burned Area Emergency Response program--a federal program that 
provides funds to stabilize and prevent degradation to natural and 
cultural resources resulting from the effects of wildland fires. 
Agencies prioritize and fund emergency treatments based on risks 
identified in damage assessments. According to Forest Service 
guidance, Burned Area Emergency Response program assessments should be 
conducted for fires that burn more than 300 acres, though damage from 
smaller fires can be assessed if federal land management agency 
officials believe that life, property, or damage to natural or 
cultural resources are at risk. From 2006 through 2010, federal 
agencies assessed damage from 20 significant human-caused wildland 
fires in the Arizona border region for emergency treatment funding 
under this program. Based on these assessments, federal officials 
recommended that funds be used to provide emergency treatment in 
response to damage from 9 of these fires and approved at least partial 
funding for 7 of these fires. For 10 of the 11 assessed fires for 
which they did not recommend emergency treatment funding, officials 
believed that the damaged areas would recover naturally in 5 years or 
less without any treatment program. 

The above examples provide some understanding of the types of 
environmental effects of significant human caused wildland fires in 
the Arizona border region, but we were unable to quantify the full 
environmental impacts for the region because comprehensive information 
is not available. For example, according to federal agency officials, 
the amount of funding provided through the Burned Area Emergency 
Response program reflects only a portion of the total monetary value 
of the environmental damages resulting from significant human-caused 
wildland fires, in part because not all such fires receive funding 
under the program. In addition, federal officials told us that many of 
the significant human-caused wildland fires that have occurred in the 
Arizona border region have likely resulted in at least some 
environmental damage, but these effects are generally not formally 
documented or recorded by federal agencies, and often it is many years 
before the extent of the damage is fully evident. Similarly, state 
agencies such as the Arizona State Forestry Division and the Arizona 
State Land Department could not provide us with data regarding the 
environmental consequences of significant human-caused wildland fires 
that occurred on state lands because, according to state officials, 
they do not maintain such data. 

Federal Agencies Did Not Conduct Investigations of All Human-Caused 
Wildland Fires and Thus Cannot Determine the Number Ignited by Illegal 
Border Crossers: 

The frequency with which illegal border crossers have caused wildland 
fires on federal lands in the Arizona border region is not fully 
known, in part because federal land management agencies did not 
conduct investigations of all human-caused wildland fires that 
occurred on their lands as called for by interagency policy. Further, 
the fires that were investigated--about 18 percent of the fires we 
examined (77 of 422 fires)--were selected for investigation based 
primarily on the availability of fire investigators, according to 
agency officials, rather than on the specific characteristics of the 
fires, such as their size or location. Without more information on the 
specific causes of these fires, the agencies lack key data that could 
help them target their fire prevention efforts. 

Federal Agencies Did Not Conduct Investigations of All Human-Caused 
Wildland Fires As Called for by Interagency Policy: 

Federal agencies cannot identify all of the human-caused wildland 
fires that were ignited by illegal border crossers on federal lands, 
in part because they did not conduct the investigations called for by 
interagency policy. This policy--Interagency Standards for Fire and 
Fire Aviation Operations, which applies to the Forest Service, BLM, 
FWS, and NPS--calls for these agencies to determine the general cause--
human or natural--for all wildland fires on federal lands they 
manage.[Footnote 29] If a wildland fire is determined to be human- 
caused, the interagency policy calls for a more in-depth investigation 
to be conducted, typically by personnel trained to conduct fire cause 
investigations. Similarly, the Wildland Fire and Aviation Program 
Management Operations Guide, which applies to BIA, also calls for 
thorough cause investigations for all wildland fires suspected to be 
human caused. 

There were 422 human-caused wildland fires that burned 1 or more acres 
on federal or tribal lands between 2006 and 2010.[Footnote 30] Of 
these, federal fire investigators conducted investigations for 77--or 
about 18 percent. Table 2 and figure 4 provide additional information 
on the fires investigated.

[A] Wildland fires occurring on Tohono O'odham tribal land are 
included in the BIA total. The Tohono O'odham Nation has assumed 
responsibility for wildland fire suppression and investigation 
responsibilities, under the Indian Self-Determination and Education 
Assistance Act, as amended. 

[End of table] 

Officials from the Forest Service, BIA, BLM, and FWS told us that the 
primary reason that many human-caused wildland fires were not 
investigated was because the agencies lacked available trained fire 
investigators. For example, both BLM and Forest Service officials told 
us the agency's law enforcement officers, who are trained to conduct 
such investigations, do not have the time to investigate all human- 
caused wildland fires because of other responsibilities, such as 
providing security for firefighters and their equipment. Similarly, an 
official from the Tohono O'odham Nation stated that, although he 
believes it is important to determine the cause of these fires, the 
nation's fire management program does not have adequate funding to 
support a wildland fire investigator. This official also stated that 
he has requested assistance from federal agencies to investigate some 
fires, but the agencies have been unable to provide such assistance 
because of other priorities. 

The lack of fire investigations is not a recent issue. A 1998 
Department of the Interior Inspector General report found weaknesses 
with the agency's ability to investigate fires, stating that seven of 
the eight BLM district offices reviewed by the Inspector General did 
not give sufficient priority to fire investigations and did not 
adequately document the fire investigations that were completed. 
[Footnote 31] Even for those fires that are investigated, federal 
officials told us a decision on whether to investigate a fire is 
generally not based on the specific characteristics of the fire, such 
as its size or location. Rather, they said the decision generally 
depends on the availability of a trained wildland fire investigator at 
the time of the fire. Although it appears the agencies have concluded 
they cannot investigate all fires because they do not have sufficient 
resources, they have not developed a strategy for determining which 
fires to investigate. Such a strategy could include specific criteria 
for identifying which fires to investigate, such as fires that are 
larger than average, that stand to burn sensitive areas, or that 
otherwise may have effects that make their origins important to 
understand. Without such a strategy, the agencies are unable to ensure 
that those human-caused wildland fires with the greatest effects are 
consistently investigated. 

Federal Fire Investigators Identified Illegal Border Crossers as a 
Suspected Cause of Ignition in 30 of the 77 Fires They Investigated: 

Based on our review of agency investigation reports, illegal border 
crossers were a suspected cause of ignition for 30 of the 77 
investigated wildland fires, or about 39 percent.[Footnote 32] Five of 
the 30 wildland fires in which illegal border crossers were a 
suspected cause burned less than 10 acres each, 16 burned from 10 to 
100 acres each, and 9 burned more than 100 acres each. These 30 
wildland fires were all located within 40 miles of the U.S.-Mexico 
border and occurred on the Coronado National Forest, Buenos Aires 
National Wildlife Refuge, or Organ Pipe Cactus National Monument (see 
figure 4 for the location of wildland fires that occurred on federal 
lands and which illegal border crossers were identified as a suspected 
cause).

[End of figure] 

Investigation reports identified illegal border crossers as a 
suspected cause of 15 wildland fires that resulted from efforts to 
signal for help, provide warmth, or cook food. For example, the 
investigation report for the 2006 Black Mesa Fire, which burned about 
170 acres, states that the wildland fire was ignited because a border 
crosser was injured and needed assistance. According to the report, a 
group of about 20 individuals crossed illegally into the United States 
and, during the trip, one person was injured and could not continue. 
The group continued without the injured person, but first started a 
fire to keep animals away and to attract attention in the hope that 
someone would rescue the injured person. In another instance--the 2009 
Bear Fire, which burned 15 acres--the investigation report states that 
a campfire was the probable cause, noting several indicators regarding 
a potential source of ignition: (1) discarded bottles and food 
wrappers with Spanish language labels were found in the area of 
origin; (2) the area is frequented by illegal border crossers and is 
adjacent to a heavily used smuggling trail; and (3) the fire was 
ignited at a time when illegal border crossers are often known to 
travel. 

The investigation reports for the remaining 15 wildland fires 
suspected to be ignited by illegal border crossers did not explicitly 
indicate a purpose for the ignition, though a couple of investigation 
reports for these fires noted that the area of ignition is known for 
drug smuggling. For instance, the investigation report for the 2010 
Horseshoe Fire, which burned about 3,400 acres, stated that evidence 
found during the investigation suggests that drug smugglers were in 
the area of ignition.[Footnote 33] 

For the other investigated human-caused wildland fires that were not 
linked to illegal border crossers, federal agency investigation 
reports identified a number of other potential human causes that could 
have caused the ignition, and in some cases the investigation reports 
did not identify any specific cause. Examples from investigation 
reports include the following: 

* Resident campfires were a suspected source of 13 wildland fires, 
including the 2009 Carr Link Fire, where a visitor to the Coronado 
National Forest was suspected of leaving a campsite for a day hike 
without properly extinguishing the campfire. 

* Other activities such as recreational shooting, welding accidents, 
sparks from all-terrain vehicles, and fireworks were a suspected 
source of 25 fires, such as the 2009 Mile Post 6 Fire on the Coronado 
National Forest, where target shooters shot rocks and sparks from the 
bullets ignited dry grass; and the 2007 San Antonio Fire, where a 
resident accidentally ignited the fire while welding. 

* Investigation reports indicate that investigators could not 
determine a cause or did not document a suspected cause for 17 fires. 
These wildland fires ranged in size from 1 acre to 5,070 acres. 

To obtain additional information on possible causes of wildland fires, 
we also reviewed fire incident reports for the 1,123 human-caused 
wildland fires that occurred on federal and tribal land in the region 
from 2006 through 2010. Fire incident reports are distinct from 
investigation reports in that they are completed for each wildland 
fire and contain overall information on the fires' size, location, and 
general cause, but they are not formal investigations into the fire's 
origin. In addition to collecting general fire information, these 
incident reports allow firefighters to include comments regarding 
their views on the fires' causes--although such comments are not 
mandatory and firefighters completing the fire incident reports often 
choose not to include this kind of information. Of the fire incident 
reports we reviewed, 57 included firefighter comments noting illegal 
border crossers as a suspected cause of the fire. Most of these (32 of 
the 57) were for wildland fires that occurred on the Tohono O'odham 
tribal land. According to a tribal official, illegal border crossers 
are a significant cause of wildland fires on tribal land and the 
purpose of the fires is usually to signal for assistance, cook food, 
or to provide warmth. Appendix III includes additional information 
about the fire incident reports we reviewed and a map identifying the 
location of the 57 wildland fires. 

Without Comprehensive Fire Investigation Results, Federal Agencies 
Lack Key Data Needed to Target Their Fire Prevention Efforts: 

Without complete data on the cause of wildland fires on the lands that 
they manage, federal agencies are hampered in their ability to target 
their efforts and resources at preventing future wildland fires. 
According to interagency guidance, the Wildfire Origin and Cause 
Determination Handbook, identifying trends in fire causes is critical 
to the success of fire prevention programs, and the results of fire 
investigations can assist in policy development. Similarly, a Forest 
Service document states that the first step in the prevention of human-
caused wildland fires is to determine the group most likely to start 
fires. However, in reviewing several agency fire prevention plans for 
the region, we found that they included only broad wildland fire 
awareness programs and activities but did not identify specific trends 
or discuss groups likely to start fires or discuss the possible role 
of illegal border crossers in contributing to fires in the region. 
Without either additional data on the ignition source of fires in the 
Arizona border region or a systematic process for using the 
information identified in investigation reports, it will be difficult 
for the land management agencies to identify more specific wildland 
fire prevention activities or better target fire prevention efforts 
and resources. 

In contrast, the experience of the Cleveland National Forest in 
California provides an example of the potential benefits of better 
targeting fire prevention efforts. In 1996, the Forest Service formed 
the Border Agency Fire Council in Southern California to help identify 
activities that could prevent future wildland fires.[Footnote 34] 
Using data on the cause of wildland fires, the council determined that 
a number of wildland fires were the result of improperly extinguished 
campfires left by illegal border crossers. In response, officials from 
the Cleveland National Forest created a border fire prevention crew 
that hikes daily on trails known to be used by illegal border crossers 
and extinguishes abandoned campfires. In 2008 alone, the forest 
reported that the fire prevention crew extinguished 101 abandoned 
campfires that, had they not been suppressed, could have grown into 
larger and more damaging wildland fires. This example demonstrates 
that with better information about the specific ignition source of 
human-caused wildland fires, the agencies could be better equipped to 
take actions that may prevent future wildland fires. 

The Presence of Illegal Border Crossers Has Complicated Fire 
Suppression Activities, and Agencies' Responses May Not Fully Address 
the Issue: 

The presence of illegal border crossers has increased the complexity 
of fire suppression activities in the border region, according to 
federal agency officials, because it can endanger firefighters' 
safety, complicate the use of radio communications, and limit the use 
of certain types of fire suppression activities. Agencies have taken a 
number of actions to mitigate the threats to firefighters in the 
Arizona border region, but these actions may not be sufficient to 
ensure that agency resources are being used most effectively, and none 
of the agencies has developed a risk-based approach for using 
resources to support fire suppression activities in the region. 

The Presence of Illegal Border Crossers Has Complicated Wildland Fire 
Suppression Activities in the Arizona Border Region: 

The presence of illegal border crossers has complicated wildland fire 
suppression activities in the Arizona border region, according to 
federal agency officials, largely because of concerns about 
firefighter safety. In 2006, the Forest Service issued a report 
stating that the Arizona border region is made more dangerous for 
firefighters because they may encounter smugglers; high-speed law 
enforcement pursuits; environments littered with trash and other 
biological hazards; and illegal border crossers who are seeking food, 
water, transportation, or rescue.[Footnote 35] While federal agency 
officials we interviewed, including fire response and law enforcement 
officials, did not identify any specific incidents in which 
firefighters had been assaulted or threatened by illegal border 
crossers, they identified several aspects of illegal cross-border 
activity that firefighters must account for while suppressing fires in 
the region. 

Firefighters may encounter armed smugglers. Federal agency officials 
told us that violence could result if firefighters encounter armed 
smugglers while suppressing fires in remote areas. They did not 
provide any examples of specific situations in which firefighters had 
experienced such violent encounters with smugglers; however, officials 
cited instances in which individuals they believed to be illegal 
border crossers were encountered during fire suppression activities. 
The fire investigation report for the recent 2011 Horseshoe Two Fire 
indicates that drug smugglers continued to use that area even as fire 
suppression activities were underway. 

Illegal border crossers may be injured or killed by suppression 
activities. A number of fire response officials told us that they 
believe many illegal border crossers generally try to avoid contact 
with firefighters in the region--which, while reducing concern for 
firefighters' safety, raises concerns about the safety of illegal 
border crossers who could be harmed or killed by fire suppression 
activities. For example, firefighters sometimes set backfires--the 
burning of grass, leaves, brush, and other fuels located between an 
advancing fire and an established control line, such as a road--to 
halt the spread of wildland fires. Given the concern about the 
possible presence of illegal border crossers in the Arizona border 
region, firefighters--or, in some cases, U.S. Border Patrol agents--
will, in some instances, first conduct a search of an area to attempt 
to identify whether illegal border crossers are in harm's way before 
igniting a backfire. This additional step can increase the resources 
and time needed to suppress the fire.[Footnote 36] 

Firefighters may reduce their use of nighttime firefighting 
activities. The potential presence of illegal border crossers has 
caused agencies to reduce their use of nighttime fire suppression 
activities and temporary overnight camps for firefighters because of 
the perceived threat to firefighters' safety. As a result, 
firefighters may have to forgo or delay some firefighting tactics, 
which in turn may allow fires to grow larger and more damaging. For 
example, a Forest Service official told us that on the first day of 
the 2009 Hog Fire, firefighters were unable to set up an overnight 
camp at the scene of the fire because no law enforcement support was 
available to provide security. According to this official, this 
allowed the fire, which had burned 200 to 300 acres at the time, to 
grow to more than 3,000 acres by the next morning; the fire ultimately 
burned nearly 17,000 acres and cost more than $700,000 to suppress. 

Illegal cross-border activity may interfere with radio communications. 
According to agency officials from several land management agencies, 
communicating by radio is difficult as a result of illegal cross-
border activity in the Arizona border region. For example, according 
to federal agency and tribal officials, illegal border crossers may 
use the same radio frequencies as firefighters, causing interference 
and limiting their ability to safely coordinate fire suppression 
activities. In one instance, a tribal official told us that the Tohono 
O'odham Nation's sole radio repeater--which allows firefighters to 
communicate over long distances--had its frequency taken over by 
illegal border crossers and is now unusable to firefighters.[Footnote 
37] The tribal official stated that the lack of access to a repeater 
limits firefighters' ability to communicate. We were also told by 
Forest Service officials that firefighters are instructed not to use 
radios when they encounter illegal border crossers because illegal 
border crossers may believe that firefighters are reporting their 
location to law enforcement and react violently. 

Volume of air traffic increases the importance of interagency 
coordination. According to federal and tribal officials, aerial fire 
suppression activities in the Arizona border region require extra 
caution because of the high volume of other federal air traffic in the 
area--particularly DHS aircraft conducting border security operations, 
such as drug interdiction or search and rescue, and DOD aircraft 
conducting training flights. According to the officials, both fire 
suppression and DHS aircraft often operate at low altitude and in the 
same areas along the border, making the risk of a midair collision 
higher than in other areas across the country. To enhance safety, they 
emphasize the importance of coordinating with agency dispatch centers 
to ensure that airspace is clear of other traffic when conducting 
aerial fire suppression activities. 

Firefighters may be distracted by the presence of illegal border 
crossers. More broadly, officials from several land management 
agencies told us the potential presence of illegal border crossers is 
a distraction to firefighters that can result in firefighters focusing 
more on their own security, or that of illegal border crossers, than 
on suppressing the fire. In addition, agency officials stated that 
firefighters have discovered the bodies of illegal border crossers, 
which further distracts them and affects their morale. 

Agencies Have Taken Steps to Mitigate Threats to Firefighters in the 
Arizona Border Region but Do Not Have a Formal Risk-Based Approach for 
Using Their Resources: 

The Forest Service has taken a number of actions to mitigate the 
threats to firefighters' safety in the Arizona border region--which 
other agencies have generally followed. In 2008, the Forest Service 
published an instructional DVD to educate federal, state, local, and 
tribal employees working along the U.S.-Mexico border on safety 
concerns and work practices that can reduce on-the-job risks.[Footnote 
38] One of the training modules specifically discusses illegal border 
crossers' effects on fire suppression activities in the region and 
special precautions that firefighters should take. The Forest Service 
also produces and distributes "International Border Watchouts" cards 
to all firefighters conducting suppression activities on the Coronado 
National Forest. These cards highlight specific risks that 
firefighters might face when suppressing fires on the forest and 
include a map identifying where--based on proximity to the border--
they are most likely to encounter these risks. 

The Forest Service has also developed a Border Fire Response Protocol, 
which recommends that firefighters working in the Arizona border 
region consider taking certain actions to mitigate the potential risks 
posed by illegal cross-border activity. One of the recommended actions 
is for fire responders to request that law enforcement support be 
dispatched to fires in the region to provide security for firefighters 
and their equipment. Officials from all five federal land management 
agencies explained that law enforcement provides security in multiple 
ways, including providing an armed presence while firefighters are 
suppressing fires or camping overnight, clearing areas of any illegal 
border crossers that might be hiding in an area where fire suppression 
activities--such as backfires--are going to occur, and guarding fire 
suppression vehicles and equipment to prevent theft. 

Officials from all of the other federal land management agencies in 
the region--BIA, BLM, FWS, and NPS--told us they generally follow the 
Forest Service's fire response protocol informally but that they have 
neither formally adopted it nor developed their own guidance to 
account for the impacts that illegal border crossers have on wildland 
fire suppression activities in the region. A number of federal 
officials in the border region from these agencies identified the lack 
of formal protocols for the four Interior land management agencies as 
a major concern, in part because without formal policies it is unclear 
that these agencies will provide the most appropriate and consistent 
fire response actions for the region. Under the Standards for Internal 
Control in the Federal Government, agencies are to employ control 
activities, which are the policies, procedures, techniques, and 
mechanisms to ensure effective program management and help ensure that 
actions are taken to avoid risk.[Footnote 39] In this case, such 
activities would include protocols for federal land management 
agencies responding to wildland fires in the region.

More broadly, the land management agencies have recognized risks 
associated with fighting wildland fires in the Arizona border region, 
but none of the agencies use a risk-based approach for allocating law 
enforcement resources in support of wildland fire suppression 
activities specific to the region. Instead, law enforcement is 
dispatched to most wildland fires whether any specific threats have 
been identified or not. Both federal fire response and law enforcement 
officials told us that not all fire suppression activities need 
security because the threat posed to firefighters by illegal border 
crossers varies by fire. Further, fire response officials told us that 
waiting for law enforcement to arrive can delay firefighting efforts; 
similarly, law enforcement officials told us that being dispatched to 
all fires regardless of the level of safety concerns has hampered 
their ability to do other high-priority work, such as conducting drug 
interdiction or fire investigations. We have previously recommended 
that, when making decisions about needed law enforcement resources and 
how to distribute those resources, federal land management agencies 
should adopt a risk management approach to systematically assess and 
address threats and vulnerabilities.[Footnote 40] This recommendation, 
which the agencies agreed with, noted that, in keeping with the 
Standards for Internal Control in the Federal Government, such an 
approach should identify risks, assess their magnitude and likelihood 
of occurrence, and use information from these assessments in 
determining the law enforcement resources needed and the best way to 
distribute those resources. However, such an approach has not been 
developed or implemented for the Arizona border region. Without a 
systematic risk-based approach that incorporates a consideration of 
the threats associated with individual fires, the agencies lack 
assurance that they are using their limited law enforcement resources 
in the most efficient manner. 

Conclusions: 

Federal land management agencies in the Arizona border region face a 
set of complex and diverse challenges in carrying out their 
responsibilities, including those posed by illegal border crossers and 
wildland fires. In general, the agencies are well aware of the threats 
associated with wildland fire suppression activities in the border 
region and have taken some steps to address them, such as following 
the Forest Service's Border Fire Response Protocol. However, gaps in 
information and inefficient deployment of limited law enforcement 
resources create operational challenges limiting the agencies' ability 
to fully address the complications they face. The agencies do not have 
in-depth information about the specific ignition sources of human- 
caused wildland fires in part because they have not conducted 
investigations for all human-caused fires--often because of limited 
resources--as called for by interagency policy. In a time of 
constrained resources and competing needs, we recognize that 
investigating all human-caused wildland fires in the Arizona border 
region may not be feasible. However, the agencies have not developed a 
strategy for determining which fires to investigate, including 
specific criteria to help identify and prioritize those fire incidents 
that should be investigated. Further, agencies do not have a 
systematic process for using the information identified in the 
investigations to inform decisions on prevention efforts. Without this 
information, it will be difficult for agency efforts to target fire 
prevention activities and resources and potentially reduce the 
incidence of human-caused wildland fires in the region. Further, the 
practice of dispatching law enforcement support to most fires, rather 
than considering the risk or safety concerns associated with 
individual fires, may delay fire suppression activities and prevent 
law enforcement from conducting other high-priority work, such as drug 
interdictions or fire investigations. Without a systematic risk-based 
approach that incorporates a consideration of the risks associated 
with individual fires, the agencies lack assurance that they are using 
their limited law enforcement resources in the most efficient manner. 
Finally, the Interior agencies have taken an important step by 
informally following the Border Fire Response Protocol developed by 
the Forest Service, but without formally adopting the protocol or 
developing corresponding protocols of their own, they lessen the 
chances that the procedures in the protocol will be consistently 
followed. 

Recommendations for Executive Action: 

We recommend that the following five actions be taken: 

* To ensure agencies have the data needed to identify wildland fire 
prevention activities and to ensure resources are effectively 
targeted, the Secretaries of Agriculture and the Interior should 
direct the Chief of the Forest Service, the Directors of the Bureau of 
Land Management, Fish and Wildlife Service, and National Park Service, 
and the Assistant Secretary for Indian Affairs to take the following 
actions: (1) re-examine the policy that all human-caused wildland 
fires be investigated; (2) once the agencies have determined the 
appropriate level of investigations, develop a strategy for 
determining which fires to investigate, including specific criteria to 
help select and prioritize those fire incidents that should be 
investigated; and (3) develop a systematic process to use the 
information identified in the investigations to better target fire 
prevention activities and resources. 

* To ensure that fire suppression activities are not unnecessarily 
delayed and that law enforcement resources are efficiently allocated, 
the Secretaries of Agriculture and the Interior should direct the 
Chief of the Forest Service and the Directors of the Bureau of Land 
Management, Fish and Wildlife Service, and National Park Service to 
develop a coordinated risk-based approach for the region to determine 
when law enforcement support is warranted for each wildland fire 
occurrence and adjust their response procedures accordingly. In 
developing this approach, officials in the region should consult with 
agencies' headquarters to ensure consistency in the approaches being 
developed for the region and for all land management agency units 
nationwide. 

* The Secretary of the Interior should direct the Directors of the 
Bureau of Land Management, Fish and Wildlife Service, and National 
Park Service, and the Assistant Secretary for Indian Affairs to 
develop border-specific fire response guidance or review existing 
guidance to determine whether it is sufficient and, if so, formally 
adopt it. 

Agency Comments and Our Evaluation: 

We provided the Departments of Agriculture, Defense, Homeland 
Security, and the Interior with a draft of this report for their 
review and comment. 

In its written comments, the Forest Service, responding on behalf of 
the Department of Agriculture, agreed with our observations and the 
two recommendations addressed to the agency. The Forest Service's 
comments are reproduced in appendix IV. 

The Department of the Interior did not provide written comments to 
include in our report. However, in an e-mail received October 24, 
2011, the agency liaison stated that Interior generally concurred with 
our recommendations and that implementing the recommendations will 
require consultation with the Department of Agriculture to ensure 
interagency consistency. Regarding our second recommendation, Interior 
noted that it disagrees that there is a lack of coordinated risk-based 
law enforcement support, but concurred that improvements and 
adjustments can be made. While we are encouraged that Interior 
acknowledges improvements can be made, based on our observations we 
continue to believe that the agency does not use a systematic risk-
based approach that incorporates a consideration of the risks 
associated with individual fires when allocating law enforcement 
resources. Interior also noted that it agrees that coordination and 
consultation within the region and across the nation for both 
responses with wildland fire and law enforcement in a refined risk-
based approach can ensure that appropriate fire suppression responses 
are implemented. Interior also provided technical comments in its e-
mail response, which we have incorporated as appropriate. 

In its written comments, the Department of Homeland Security agreed 
with our observations about the complex and diverse challenges that 
federal land management agencies face in the Arizona border region. 
The department's comments are reproduced in appendix V. 

The Department of Defense did not provide written or technical 
comments in response to our report. 

As agreed with your offices, unless you publicly announce the contents 
of this report earlier, we plan no further distribution until 30 days 
from the report date. At that time, we will send copies to the 
Secretaries of Agriculture, Defense, Homeland Security, and the 
Interior; the Chief of the Forest Service; the Assistant Secretary for 
Indian Affairs; the Directors of the Bureau of Land Management, Fish 
and Wildlife Service, and National Park Service; appropriate 
congressional committees; and other interested parties. In addition, 
the report will be available at no charge on the GAO website at 
[hyperlink, http://www.gao.gov]. 

If you or your staffs have questions about this report, please contact 
me at (202) 512-3841 or mittala@gao.gov. Contact points for our

Appendix I: Scope and Methodology: 

The objectives of our review were to determine (1) the number, cause, 
size, and location of wildland fires in Arizona that occurred within 
100 miles of the U.S.-Mexico border from 2006 through 2010; (2) 
economic and environmental effects of significant human-caused 
wildland fires (i.e., those fires that burned 10 or more acres); (3) 
the extent to which federal agencies determined that illegal border 
crossers were the ignition source of fires on federal lands; and (4) 
ways, if any, in which the presence of illegal border crossers has 
affected fire suppression activities in the Arizona border region. 

To determine the extent of wildland fire occurrence in the Arizona 
border region, we collected federal and state fire occurrence data 
from databases at the National Interagency Fire Center (NIFC)[Footnote 
41] for fires that occurred within Arizona during calendar years 2006 
through 2010.[Footnote 42] We obtained data for the Forest Service 
through its Fire Statistics System, extracting data from this system 
for all fires that occurred within the Coronado National Forest. We 
obtained data for the Department of the Interior's Bureau of Indian 
Affairs (BIA), Bureau of Land Management (BLM), and National Park 
Service (NPS) through its Wildland Fire Management Information 
Database, extracting data for all fires that occurred on Interior land 
units in Arizona. We obtained data for the Department of the 
Interior's Fish and Wildlife Service (FWS) through its Fire Management 
Information System, extracting data for all fires on the agency's land 
units within the Arizona border region. Lastly, we obtained data for 
lands managed by the state of Arizona, local governments, and private 
residents through the Fire and Aviation Management Data Warehouse, 
extracting data for all fires in the state of Arizona. From these 
data, we geographically located each fire based on latitude and 
longitude coordinates using geographic mapping software. We filtered 
the data to include only fires that occurred in Arizona within 100 
miles of the U.S.-Mexico border. A number of records in the data set 
did not include geographic coordinates, preventing us from verifying 
the location of the fires--and, as a result, these fires are not 
included in our analysis. For the fires we were able to verify as 
within the Arizona border region, we then analyzed the data to 
identify the acreage burned and general cause--human or natural--cited 
for ignition. We assessed the reliability of the data we used by 
reviewing information about the underlying database systems and 
discussing the data with agency officials responsible for managing 
these databases, and determined that the data were sufficiently 
reliable for the purposes of presenting acreage burned and general 
cause of fires occurring during calendar years 2006 through 2010. 
Because NIFC does not manage the Department of Defense's (DOD) fire 
occurrence data, we also obtained information from DOD regarding 
wildland fire occurrence on its lands in the region and included these 
data in our overall figures. DOD officials identified and provided 
data for those fires on DOD-managed lands located within the Arizona 
border region. In our assessment of the data, we determined that these 
data were not sufficiently reliable for our purposes of presenting a 
comprehensive account of fires and acreage burned on DOD lands during 
calendar years 2006 through 2010. However, we included the information 
we were provided because they were the only data available. 

During the course of our review, in 2011, two significant fires 
occurred in the Arizona border region--the Horseshoe Two and Monument 
fires. We could not include information on these two fires in our data 
analysis because at the time of our review, the data from the federal 
agencies on these fires were not complete and could not be determined 
as reliable. However, given the significance of these fires, we have 
included some descriptive and preliminary information about them 
throughout the report, as appropriate. 

To determine the economic and environmental effects of significant 
human-caused wildland fires, we first identified those human-caused 
fires that burned 10 or more acres (which we consider significant 
fires for the purposes of this report) using the data collected in the 
previous objective. We then obtained additional information on these 
fires from the federal and state land management agencies included in 
our review. Each agency provided us with the amount of funds obligated 
to suppress the fires. Because some funding obligations for individual 
fires occurred over multiple years, we did not adjust these figures 
for inflation. In addition, the federal land management agencies 
provided us with data on environmental assessments conducted in 
response to these fires, as well as data on environmental restoration 
funds requested or provided in response to significant human-caused 
wildland fires. (The state of Arizona does not conduct such 
assessments or provide such funds.) We also identified the grazing 
allotments on Forest Service lands that were within the Arizona border 
region and could have been affected by human-caused wildland fires. 
For these allotments, we requested data from Forest Service's range 
management officials for any damages and repairs to these lands as a 
result of significant human-caused wildland fires. In addition, we 
reviewed studies conducted by academicians and wildland fire 
organizations on the economic impact of wildland fires.[Footnote 43] 
Our review of the economic impact studies was not comprehensive to 
include all studies that may exist. Finally, we visited the region and 
discussed with federal, tribal, and state officials, as well as 
private industry representatives and private citizens in the ranching 
community, the economic and environmental damage that has occurred as 
a result of human-caused wildland fires. 

To determine the extent to which federal agencies determined that 
illegal border crossers were the ignition source of wildland fires on 
federal lands, we reviewed agency documents to identify criteria for 
conducting investigations into the ignition source of human-caused 
wildland fires. We then identified all human-caused wildland fires and 
requested fire investigation reports for each fire from Forest Service 
and the Interior agencies. Because of extensive resource commitments 
on the part of the agencies in response to the severe 2011 wildland 
fire season in Arizona and the amount of resources needed to provide 
us with investigation reports, we limited our request to investigation 
reports for human-caused wildland fires burning at least 1 acre, which 
cumulatively comprised more than 99 percent of the acreage burned by 
human-caused wildland fires in the region from 2006 through 2010. We 
reviewed and evaluated the fire investigation reports to determine the 
extent to which fire investigations were conducted for human-caused 
wildland fires, and, for those fires for which investigations were 
conducted, we identified the extent to which officials identified 
illegal border crossers as the source of ignition. Additionally, we 
reviewed fire incident reports created by fire response personnel for 
all human-caused wildland fires to identify the extent to which they 
cited illegal border crossers as a potential source of ignition. 

To determine ways in which the presence of illegal border crossers 
have affected fire response activities in the Arizona border region, 
we reviewed national and regional land management wildland fire 
guidance to identify any practices unique to regional land management 
units developed in response to illegal cross-border activity. We also 
identified and reviewed training materials and other documentation, 
such as the Forest Service's Working Along the United States-Mexico 
Border DVD and the Coronado National Forest's Border Fire Response 
Protocol, and interviewed land management, firefighting, and law 
enforcement officials to further identify specific actions taken in 
the border region. Further, during our site visits, we discussed with 
federal and nonfederal officials their experiences fighting wildland 
fires in the region. 

We conducted this performance audit from December 2010 to November 
2011 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.

Notes: Duration was identified by determining the days elapsed between 
when a fire was reported "discovered" and when it was declared either 
"controlled" or "out," depending on what information agencies report 
in their fire occurrence data. 

[A] Data provided by federal and state agencies did not include enough 
information for us to determine duration. 

[B] The Department of Defense did not provide us with information on 
suppression costs associated with each fire. 

[C] The Forest Service did not provide us with information on 
suppression costs associated with the 2008 Apache Fire.

[End of table] 

In addition to the formal investigations into ignition sources, fire 
incident reports--documentation completed by fire responders on the 
size, location, and general cause of each fire--sometimes contain fire 
responders' views on the cause of the wildland fire. Fire incident 
reports we reviewed noted illegal border crossers as a suspected cause 
for 57 wildland fires in the region. However, the purpose of these 
reports is to document general wildland fire occurrence data and the 
reports are not indicative of a formal investigation into the fire's 
origin (see figure 5 for location of wildland fires). Table 5 provides 
information on wildland fires in which officials documented through 
fire incident reports that illegal border crossers are a suspected 
cause for the wildland fire.

Dear Ms. Mittal:  

Thank you for the opportunity to review and comment on the draft U.S. 
Government Accountability Office (GAO) Report on "Arizona Border 
Region: Federal Agencies Could Better Utilize Law Enforcement 
Resources in Support of Wildland Fire Management Activities" (GAO-12-
73). The Forest Service has reviewed the report and concurs with the 
report's observations and recommendations.  

The agency does not have any major comments on the report or the 
recommendations, except to mention with regard to Recommendation 3 
that the Southwest Coordinating Group has been working on a standard 
interagency border protocol (to include most if not all of the Coronado 
National Forest guidance). This protocol would guide firefighters and 
also apply to Department of the Interior agencies.  

Thank you again for the opportunity to review your draft report. If 
you have any questions, please contact Donna M. Canniest Chief 
Financial Officer, at 202-205-1321 or dcarmical@fs.fed.us.

Re: Draft Report GAO-12-73, "Arizona Border Region: Federal Agencies 
Could Better Utilize Law Enforcement Resources in Support of Wildland 
Fire Management Activities" 

Dear Ms. Mittal: 

Thank you for the opportunity to comment on this draft report. The 
U.S. Department of Homeland Security (DHS) appreciates the U.S. 
Government and Accountability Office's (GAO) work in planning and 
conducting its review and issuing this report. 

The Department is pleased to note GAO's acknowledgment of the complex 
and diverse challenges that federal land management agencies in the 
Arizona border region face in carrying out their responsibilities, 
including those posed by illegal border crossers. We note the report 
does not contain any recommendations specifically directed at the DHS. 
The Department, particularly U.S. Customs and Border Protection, 
however, remains committed to continuing its work with interagency 
partners, such as the U.S. Departments of Agriculture and Interior, to 
identify and mitigate adverse impacts to wildland fire management 
activities. 

Again, thank you for the opportunity to review and comment on this 
draft report. We look forward to working with you on future Homeland 
Security issues. 

Sincerely, 

Signed by:

Footnotes: 

[1] To achieve land management objectives federal land mangers 
sometimes use prescribed burns--fires set deliberately by land 
managers under weather, fuel, and temperature conditions that enable 
the fire to be controlled at a relatively low intensity level. In this 
report, we use the term "human-caused wildland fires" to refer only to 
human-caused fires other than prescribed burns. 

[2] Suppression cost obligations and damages incurred as a result of 
these fires are estimates reported by federal agencies. We did not 
independently verify the accuracy of these data. 

[3] GAO, Federal Lands: Adopting a Formal, Risk-Based Approach Could 
Help Land Management Agencies Better Manage Their Law Enforcement 
Resources, [hyperlink, http://www.gao.gov/products/GAO-11-144] 
(Washington, D.C.: Dec. 17, 2010). 

[4] In this report we refer to the area in Arizona that is within 100 
miles of the U.S.-Mexico border as the Arizona border region. 

[5] NIFC, located in Boise, ID, is the nation's logistical support 
center for controlling and extinguishing wildland fires and 
coordinates the mobilization of fire suppression supplies, equipment, 
and personnel at the federal, regional, and local levels. 
Additionally, NIFC maintains historical fire occurrence data for the 
Department of Agriculture's Forest Service and the Department of the 
Interior's Bureau of Indian Affairs, Bureau of Land Management, Fish 
and Wildlife Service, and National Park Service. NIFC also maintains 
historical fire occurrence data collected by state agencies, including 
the Arizona State Forestry Division, for fires on nonfederal lands. 

[6] Unless otherwise noted, all references in this report are to 
calendar years rather than fiscal years. We did not include fires that 
occurred in calendar year 2011 because federal agencies do not collect 
fire documentation from local units or conduct quality assurance 
checks on data until the end of the calendar year, and therefore 2011 
data were not complete and may not be reliable. 

[7] The Department of the Interior's Bureau of Reclamation manages a 
very small amount of federal land in the Arizona border region. We did 
not include this agency in our review.

[14] DOD did not provide fire size data for 13 fires occurring on its 
lands. 

[15] The dollar values are as provided by the agencies and have not 
been adjusted for inflation. Based on preliminary information from the 
Forest Service and Department of the Interior, the 2011 Horseshoe Two 
and Monument fires together cost more than $70 million to suppress-- 
twice the total reported federal and state obligations for suppressing 
all significant human-caused wildland fires from 2006 through 2010. 
However, as noted earlier, these fires occurred after the period of 
our data analysis and we have not independently assessed the validity 
of this cost information. 

[16] These amounts do not include suppression cost data from DOD or 
local entities with fire management responsibilities, such as 
individual tribes, municipalities, or local fire protection districts. 
In addition, for those agencies that provided us with data, 
suppression costs can continue to be incurred several years after a 
fire occurrence; thus, our analysis may not include all fire 
suppression costs associated with these fires. 

[17] See appendix II for detailed information on funding obligations, 
duration, and burned acreage associated with each significant human- 
caused wildland fire that occurred in the Arizona border region from 
2006 through 2010. 

[18] Western Forestry Leadership Coalition, The True Cost of Wildfire 
in the Western U.S. (April 2010). 

[19] To provide access to grazing, both BLM and the Forest Service 
divide their rangelands into allotments, which can vary in size from a 
few acres to hundreds of thousands of acres of land. Because of the 
land ownership patterns that occurred when the lands were settled, the 
allotments can be adjacent to private lands, or they can be 
intermingled with private lands. 

[20] For fires that occurred during 2011 (subsequent to the period of 
our data analysis), the Forest Service has reported preliminary 
estimates of at least $3.8 million in damage to federal grazing 
allotments, including from the Horseshoe Two Fire--which occurred on 
the Coronado National Forest. According to the Forest Service, the 
Horseshoe Two fire damaged approximately 120 miles of fence and 
destroyed at least 50 improvements, such as corrals, pipelines, water 
tanks, and wells. 

[21] The Forest Service was the only agency that reported to us that 
it provided funds or materials to restore damaged rangeland 
improvements in response to significant human-caused wildland fires 
that occurred from 2006 through 2010. The Forest Service manages about 
320 active federal grazing allotments in the Arizona border region. 

[22] Another Forest Service official reported providing an additional 
$65,000 for fencing material for 2 additional allotments damaged by 
fire, and added that an additional 15 had been affected by wildland 
fires from 2006 through 2010--although this official could not 
determine how much of this damage resulted from significant human- 
caused wildland fires and how much resulted from fires that were 
smaller or naturally ignited. 

[23] Cochise County is one of four counties entirely within the 
Arizona border region. Five additional counties are partially within 
the region. 

[24] The 2011 Horseshoe Two Fire did require the evacuation of Portal 
for several days, causing businesses in the community to close, but 
the precise economic effect of the evacuation on the region is 
likewise unknown. 

[25] Dennis L. Lynch, "What Do Forest Fires Really Cost?," Journal of 
Forestry (September 2004). 

[26] As we have reported, wildland fire can have dramatic positive and 
negative environmental effects. See GAO, Wildland Fires: Forest 
Service and BLM Need Better Information and a Systematic Approach for 
Assessing the Risks of Environmental Effects, GAO-04-705 (Washington, 
D.C.: June 24, 2004). 

[27] The Endangered Species Act of 1973 protects plant and animal 
species that are either facing extinction (endangered species) or are 
likely to face extinction in the foreseeable future (threatened 
species) and protects the ecosystems upon which they depend. 

[28] Riparian areas--the narrow bands of green vegetation along the 
banks of rivers and streams--are widely recognized as crucial to the 
overall ecological health of rangelands. 

[29] DOD is not a signatory to this policy and does not generally 
conduct investigations into the causes of wildland fires on its 
properties. As a result, we did not include the agency in our analysis. 

[30] These 422 fires include those that occurred on Forest Service, 
BIA, BLM, NPS, FWS, or tribal land. Given the elevated level of 
wildland fire activity that occurred during the 2011 fire season in 
the Arizona border region, we limited our analysis to human-caused 
wildland fires burning 1 acre or more, rather than all human-caused 
fires, in order to obtain data needed for this review without creating 
an unreasonable burden for fire and law enforcement officials 
providing us with the data. We also did not include the 36 human-
caused wildland fires that burned 1 or more acres on DOD land in the 
Arizona border region. See appendix I for more information on our 
methodology. 

[31] BLM, Reimbursement of Firefighting Costs, Bureau of Land 
Management, 98-I-551 (Washington, D.C.: July 1998). 

[32] Some investigations resulted in the identification of more than 
one potential ignition source, meaning that the total number of 
suspected ignition sources is greater than the total number of fires 
investigated. 

[33] The 2011 Horseshoe Two Fire was not included as part of our 
analysis and is not reflected in our overall number of fires suspected 
to be caused by illegal border crossers. However, the investigation 
report for the fire was completed in June 2011 and stated the area of 
origin had no reported lightning strikes, the use of motor vehicles in 
the area was not probable, and the area was not known to be used by 
recreational campers. The investigation report also documents that 
camping fires used to keep warm are common in the area of origin due 
to the volume of illegal border crossers who travel through the region. 

[34] The Border Agency Fire Council is made up of 43 U.S. and Mexican 
government agencies and organizations representing fire protection and 
law enforcement personnel, legislators, emergency responders, natural 
resource managers, and elected officials that address public safety 
issues pertaining to wildland fire along the U.S.-Mexico border.

Service and Missoula Technology and Development Center; Personal 
Safety of Federal Land-Management Field Employees Working Along the 
Mexican Border; 0067-2802-MTDC (2006). 

[36] According to Border Patrol and federal land management agency 
officials, Border Patrol agents do not generally participate in 
wildland fire suppression activities. However, in some situations, 
they may provide certain types of assistance during these activities, 
such as providing temporary security for firefighters until federal 
land management agency law enforcement can arrive.

[42] We did not include fires that occurred in calendar year 2011 
because federal agencies do not collect fire documentation from local 
units or conduct quality assurance checks on data until the end of the 
calendar year, and, therefore, 2011 data are not yet complete and may 
not be reliable.
