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...

Background information. This fuels reduction project, which was conducted by the Bureau of Land Management’s (BLM’s) Rio Puerco Field Office, consisted of woodland habitat restoration in the Zuni Mountains approximately 45 miles south of Grants, New Mexico. Topography of the landscape includes mesas and canyons, with north-facing slopes dominated by stands of ponderosa pine with an open, grassy understory. Like other places in the American West, pinyon and juniper have encroached into open meadows and stands of ponderosa pine, which is most likely because of the lack of a natural fire regime. This change to the wooded landscape has dramatically increased hazardous fuels buildup and the associated risk of wildfire,...

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...

This data release provides data for the single site in the United States (U.S.) that has public record of germanium (Ge) production. Germanium, which is currently classified as a critical mineral in the U.S., is also extracted as a byproduct from deposits in Alaska, Washington, and Tennessee. However, there is no public information that documents germanium production from these deposits. Current annual production of refined germanium is led by China at 85,000 tons, while estimates place U.S. reserves near 2,500 tons. Reported production of germanium in the U.S. is limited to one site, the Apex mine in Washington County, Utah. The Apex mine produced gallium (Ga) and germanium as primary products during the mid-1980s....

This data release provides the descriptions of approximately 20 U.S. sites that include mineral regions, mines, and mineral occurrences (deposits and prospects) that contain enrichments of lithium (Li). This release includes sites that have a contained resource and (or) past production of lithium metal greater than 15,000 metric tons. Sites in this database occur in Arkansas, California, Nevada, North Carolina, and Utah. There are several deposits that were not included in the database because they did not meet the cutoff requirement, and those occur in Arizona, Colorado, the New England area, New Mexico, South Dakota, and Wyoming. In the United States, lithium was first mined from pegmatite orebodies in South...

As part of a broader effort to increase the ability of federal agencies to understand and adapt to changes in climate variability and hazard profiles, the Colorado Bureau of Land Management has commissioned an on-going research effort to gather and analyze information on the potential climate-related vulnerabilities of the numerous communities and businesses that rely upon the state’s 8.4 million acres of BLM-managed public lands. In addition to a comprensive final report (Colorado Bureau of Land Management: Social Climate Vulnerability Assessment), the project team has produced three short, easy to read "Fact Sheets" aimed at providing a concise view of each of the project's components and their major findings.

The Lower Truckee River originates in the Sierra Nevada and flows through public, private, and tribally owned lands, including 31 miles of the Pyramid Lake Paiute Tribe (PLPT) reservation, terminating in Pyramid Lake within the reservation. Once remarkably productive, a century of man-made changes have heavily degraded the river system, leaving it inundated with invasive weeds. Significant damage occurred as part of a 1960s flood control project, including river downcutting, depression of the groundwater table, and lowering of Pyramid Lake by as much as 81 vertical feet. By the 1970s, the river had lost roughly 90% of its forest canopy, 40% of its resident bird species, and had no resident Kooeyooe (also spelled...

BLM has the ability to enter into “Stewardship Contracts” to make forests and rangelands more resilient to natural disturbances. The contracts allow companies and communities to retain forest and rangeland products in exchange for services like thinning trees and brush or removing dead wood. Long-term contracts foster a public-private partnership to restore forest and rangeland health at a savings to taxpayers by allowing contractors to invest in equipment and infrastructure for making wood products or producing biomass energy. The Gerber Stew Stewardship Contract was awarded in September 2004 to a firm based in Bend, Oregon to implement restoration treatments and projects in BLM’s Klamath Falls Resource Area....

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...

For thousands of years, much of the San Luis Valley basin of south-central Colorado was made up of a series of lakes, marshes, and shallow playa basins that were integral to the lives of indigenous peoples. By the mid-1900s, the basins had dried up from the diversion of water sources for irrigation and became known as the “Dry Lakes.” In 1965, BLM began a series of wildlife habitat projects to restore some of the historic wetland characteristics and processes, and 9,600 acres of the former “Dry Lakes” area became known as Blanca Wetlands. BLM designated the Blanca Wetlands Area (BWA) as an “Area of Critical Environmental Concern” (ACEC) in 1991, due to its high importance for wildlife and recreational values. Today...

The desert grasslands found within the Las Cienegas National Conservation Area (LCNCA) include some of the rarest habitats in the American Southwest and are home to six endangered species. These grasslands have degraded over the last 100 years into mesquite woodlands due to grazing practices, fire suppression policies, and the introduction of non-native plant species. The loss of grassland has encouraged erosion, reduced watershed function, and decreased available habitat for pronghorn antelope and other species. In 2009 and 2010, BLM implemented a grassland restoration project on over 3,000 acres, out of an identified 20,000 acres of degraded grassland found within the LCNCA. The project has removed mesquite trees...
As part of a broader effort to increase the ability of federal agencies to understand and adapt to changes in climate variability and hazard profiles, the Colorado Bureau of Land Management has commissioned an on-going research effort to gather and analyze information on the potential climate-related vulnerabilities of the numerous communities and businesses that rely upon the state’s 8.4 million acres of BLM-managed public lands. This report contains the initial findings of this project, and details work conducted between 2015 and 2017 centered around three main questions: 1. What efforts are currently underway within the Colorado BLM to address changes in climate and the climate vulnerabilities of public land...
The Colorado office of the Bureau of Land Management (BLM), which administers 8.4 million acres of Colorado’s surface acres, and more than 29 million acres of sub‐surface mineral estate, has been charged with developing a climate adaptation strategy for BLM lands within the state. The assessments presented herein present a statewide perspective on the potential future influences of a changing climate on species and ecosystems of particular importance to the BLM, with the goal of facilitating development of the best possible climate adaptation strategies to meet future conditions. The Colorado Natural Heritage Program conducted climate change vulnerability assessments of plant and animal species, and terrestrial...
