Background information.—Historically, the Powell River supported abundant and diverse populations of freshwater mussels. In recent decades, mussel density and species richness have declined and many freshwater mussel species are listed as either State or Federally threatened or endangered species. Environmental degradation from coal mining has been identified as one of the drivers of this decline. An example is the 1996 Lone Mountain slurry spill that directly affected mussel populations, as well as their host fish species. Freshwater mussels feed by filtering small particles from water, thereby improving water quality and providing an essential ecosystem service in rivers and streams. Mussels also serve as a food...

The Anacostia Watershed lies within the Chesapeake Bay drainage basin, and is one of the most urban watersheds within the basin. According to the Fish and Wildlife Service, the watershed spans over 175 square miles between Maryland and the District of Columbia and is considered by many to be one of the most degraded waterways in the United States. Watts Branch is a tributary stream of the Anacostia River, and flows into the Potomac River which eventually empties into the Chesapeake Bay. In 2010, several partnerships were formed to restore a section of the Watts Branch stream and riparian area. The restoration efforts were focused on a highly polluted 1.8 mile stretch of the stream, running from the border of Prince...

Background information.— The Powell and Clinch Rivers provide vital habitat for many forms of wildlife and are inhabited by one of the world’s richest and most diverse assemblages of freshwater mussels (U.S. Fish and Wildlife Service, 2003). The rivers are also multiple-use recreation areas and a valuable water source that supplies water for the residents of Lee County, Virginia. The Lone Mountain coal slurry spill released sediment and hazardous substances affecting water quality and impacting 12 Federally listed mussels and critical habitat for 2 Federally listed fish. Fish and mussel habitat depends on the riparian habitats surrounding the river. In order to recover lost fish and mussel habitat, the Lone Mountain...
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. Settlement funds from the California Gulch Superfund site have been used to improve instream aquatic habitat and increase brown trout (Salmo trutta) populations in the Arkansas River. The upper Arkansas River Basin is a high-elevation mountain river that supports trout populations. Historically characterized by a relatively narrow channel with fast moving water, recent degradation of the upper Arkansas River due to historic land-use practices have contributed to an altered river channel and a decrease in important habitat features for trout, such as deep-water pools. This restoration project was designed to address three major issues: bank erosion, altered river channel morphology, and degraded...

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.— The Lone Mountain slurry spill injured two endangered fish species in the Powell River—the yellowfin madtom ( Noturus flavipinnis) and the slender chub ( Erimystax cahni). The yellowfin madtom was historically widespread throughout the Upper Tennessee River drainage but was presumed extinct at the time of its formal scientific description. The discovery of three surviving but geographically isolated populations in the late 1970s and early 1980s resulted in its listing as a threatened species. The slender chub was also once relatively common in the Powell River but is now listed as one of the most narrowly distributed minnows in North America. Both the yellowfin madtom and the slender chub...
Background information.—The Powell River watershed has a long history of coal mining. Prior to August 3, 1977, Virginia laws and regulations required the reclamation of areas affected by coal surface mining, but there were no regulations addressing reclamation of underground mines. Flows or seeps from these abandoned mines have long degraded the waters of the Powell River watershed (U.S. Department of Agriculture, 2008). Water that is discharged from these sites can be highly acidic and it commonly contains high concentrations of dissolved iron and aluminum sulfates. This acid mine drainage degrades the water quality of streams and water supplies and is a major contributor to aquatic habitat degradation. Led by...
