Background information.—On July 8, 2012, lightning ignited a fire on Bureau of Land Management-managed land on the Miller Homestead in Harney County, Oregon. High winds combined with unusually hot and dry conditions spread the fire through dry grass and sagebrush and 160,801 acres were burned before the fire was contained on July 24, 2012. In the aftermath, it was determined that ecological restoration was necessary since the majority of the fire occurred within prime habitat for sage-grouse, and the fire had burned with such severity that it removed vegetation down to bare soil. Without rehabilitation efforts, desirable vegetation would be unlikely to reestablish and the site would be open to invasion by noxious...

El estado de Chihuahua es el más extenso de la República Mexicana, representa el 12.6% del territorio del país (INEGI, 2001) y posee una amplia gama de recursos naturales de los que se desprenden diversas actividades económicas (INEGI, 2003), por lo anterior resulta indispensable la disponibilidad de información eficiente de los recursos naturales que permita el manejo adecuado de los mismos. La ley forestal de nuestro país, señala que la evaluación de los recursos naturales debe integrar “información estadística y cartográfica”, que permita conocer la dinámica del cambio de vegetación forestal, para poder evaluar las tasas de deforestación y sus principales causas (CONAFOR, 2010). Actualmente la cartografía...

Background information. The South Canyon project area consists of 121,000 acres within the Upper Sevier River Watershed in southern Utah. This watershed is ranked as a high priority for restoration because of degraded riparian and upland vegetation and erosion, the presence of hazardous fuels placing communities at increased risk of wildfire, and degraded greater sage-grouse (Centrocercus urophasianus) and mule deer (Odocoileus hemionus) habitat because of the expansion and infilling of pinyon and juniper. In particular, this project was designed to reestablish and maintain sagebrush semi-desert habitat, open travel corridors, and provide benefits to sage-grouse and mule deer within and immediately adjacent to the...

Background information.—The Long Draw fire was ignited by a lightning strike on July 8, 2012 on land southwest of Burns Junction, Oregon. Within 2 hours, the fire had burned several thousand acres. By the time of containment on July 16, 2012, the fire had burned a total of 558,198 acres of land that had previously provided forage for livestock and wild horses and habitat for sage-grouse and other wildlife. As a consequence of this fire, the burned area faced the immediate risks of erosion and invasion by noxious weeds. The Bureau of Land Management’s Vale District responded to this threat with the Long Draw Fire Emergency Stabilization and Rehabilitation Plan, which is designed to ensure recovery and protection...

Background information.—The Pioche/Caselton Wildland-Urban Interface Project (WUI Project) was conducted by the Bureau of Land Management’s Ely District to reduce the threat of wildfire to the towns of Pioche and Caselton in southeastern Nevada. From 1980 to 2008, 149 wildfires were recorded near Pioche and Caselton and 9 of these fires each burned approximately 3,000 acres. In 2005, the Nevada Community Wildfire Risk/Hazard Assessment for Lincoln County determined that the risk of wildfire for the two towns was “extreme” (Resource Concepts, Inc., 2005). That report recommended implementing large fuels reduction treatments in order to reduce the risk of wildfire to Pioche and Caselton. In response, the Ely District...

The Kanab Creek Project Area encompasses 130,000 acres in southern Utah. This project area receives National attention because it is home to the Paunsagunt mule deer herd which are prized by trophy hunters, and because it supports the southernmost population of greater sage grouse within the western United States. One of the focuses of this project area has been to conduct treatments that cross jurisdictional boundaries, by working closely with private landowners, Natural Resource Conservation Service (NRCS) and Utah’s Watershed Restoration Initiative, to provide landscape-level benefits for sage grouse. Telemetry data show that sage grouse are actively using older treatment areas, and newer treatments will expand...

The Central Arizona Grassland Conservation Strategy (CAGCS) was signed (2010) by three signatory agencies to the charter with complementary roles and responsibilities in managing historic grassland ecosystems and/or the wildlife species that inhabit them. The Bureau of Land Management (BLM) management emphasis within the Agua Fria National Monument (AFNM) is to conserve and restore diverse habitats, vegetative communities and corridors of connectivity to sustain a wide range of native species. The Arizona Game and Fish Department (AGFD) hold the public trust responsibility of managing the wildlife that inhabits these ecosystems. This includes but is not limited to gathering and managing wildlife data, and providing...

Sky Island grasslands of central and southern Arizona, southern New Mexico and northern Mexico form the “grassland seas” that surround small forested mountain ranges in the borderlands. Their unique biogeographical setting and the ecological gradients associated with “Sky Island mountains” add tremendous floral and faunal diversity to these grasslands and the region as a whole. Sky Island grasslands have undergone dramatic vegetation changes over the last 130 years including encroachment by shrubs, loss of perennial grass cover and spread of non-native species. Changes in grassland composition and structure have not occurred uniformly across the region and they are dynamic and ongoing. In 2009, The National Fish...

Background information. Characterized by a vast landscape dotted with sagebrush and juniper-clad foothills, the area surrounding the Bureau of Land Management’s (BLM’s) Burley Field Office in Idaho is home to a variety of species, such as the greater sage-grouse (Centrocercus urophasianus), mule deer (Odocoileus hemionus), antelope (Antilocapra americana), bighorn sheep (Ovis canadensis), and pygmy rabbit (Brachylagus idahoensis). Many of these species depend on the sagebrush steppe ecosystem that was historically present in this region. Starting in the late 1800s with the Euroamerican settlement of the west, this sagebrush steppe ecosystem has been rapidly changing into woodlands dominated by Utah juniper (Juniperus...

The Tohono O’odham Nation spans 2.8 million acres of Sonoran Desert habitat, ranging from grasslands in higher-rainfall areas on the east to desert scrub that dominates the drier northern and western regions. For the last three centuries, cattle-raising has provided a source of cash, food for community feasts and ceremonies, social status and political clout. However, cattle running in common made grazing and genetic management difficult and resulted in lower prices for livestock sold off the reservation. In the 1930s, without consulting local producers, the Nation was fenced into nine grazing districts, fragmenting grazing territories and keeping users from customary use areas. The result: resentment toward government...

Background information. The South Beaver area encompasses 145,000 acres in Beaver County in southern Utah and contains public, State, and private lands. The area is crucial mule deer (Odocoileus hemionus) winter habitat, and it contains important elk (Cervus elaphus) habitat and occupied sage-grouse (Centrocercus urophasianus) habitat (U.S. Fish and Wildlife Service, 2013). Nearby population growth and the construction of Interstate 15 have increased the importance of this area for wildlife, but the encroachment of pinyon and juniper have nearly eliminated any possible use of this area by sage-grouse and greatly reduced the amount of sagebrush and other forage available for deer and elk. Restoration in this area...
