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 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...
