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...

Establishment of native plant populations on disturbed roadsides was investigated at Bryce Canyon National Park (BCNP) in relation to several revegetation and seedbed preparation techniques. In 1994, the BCNP Rim Road (2,683?2,770 m elevation) was reconstructed resulting in a 23.8-ha roadside disturbance. Revegetation comparisons included the influence of fertilizer on plant establishment and development, the success of indigenous versus commercial seed, seedling response to microsites, methods of erosion control, and shrub transplant growth and survival. Plant density, cover, and biomass were measured 1, 2, and 4 years after revegetation implementation (1995?1998). Seeded native grass cover and density were the...

The data are from the Sediment Placement Projects on Sandy Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) prior to Hurricane Sandy.This dataset represents the approximate locations of sediment placement projects along the U.S. North Atlantic coast from Maine through Virginia prior to the time that Hurricane Sandy made landfall in October 2012.The sediment placement projects were identified as part of an inventory of habitat modifications to sandy beach habitat within the U.S. Atlantic Coast breeding range of the federally-threatened piping plover. Sediment placement projects included in the inventory were beach nourishment projects, storm damage reduction projects, beneficial...

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,...
This dataset represents beach scraping after Hurricane Sandy. These data are part of a broader project Inventory of Habitat Modifications to Tidal Inlets and Sandy Oceanfront Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) as of 2015: Maine to North Carolina. Beach scraping modified sandy beach habitat in each of the states within the U.S. Atlantic Coast breeding range of the piping plover during the three years after Hurricane Sandy. The beaches of the Peconic Estuary of New York were the least modified by beach scraping, with only 0.02 miles (0.03 km) of sandy beach habitat modified by beach scraping between 2012 and 2015. Less than 1 mile (1.6 km) of sandy beach habitat...

This dataset represents beach armor after Hurricane Sandy, including outfalls and proposed sites. These data are part of a broader project Inventory of Habitat Modifications to Tidal Inlets and Sandy Oceanfront Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) as of 2015: Maine to North Carolina. The total length of oceanfront shoreline between Georgetown, ME, and the North Carolina-South Carolina boundary that has been armored is at least 476.81 miles (767.35 km; 27% of the total shoreline length). This assessment is a minimum number because some structures are buried and not visible in aerial imagery; in addition, historical records or inventories of hard stabilization...

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...

Communities of plants, biological soil crusts (BSCs), and arbuscular mycorrhizal (AM) fungi are known to influence soil stability individually, but their relative contributions, interactions, and combined effects are not well understood, particularly in arid and semiarid ecosystems. In a landscape-scale field study we quantified plant, BSC, and AM fungal communities at 216 locations along a gradient of soil stability levels in southern Utah, USA. We used multivariate modeling to examine the relative influences of plants, BSCs, and AM fungi on surface and subsurface stability in a semiarid shrubland landscape. Models were found to be congruent with the data and explained 35% of the variation in surface stability...

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...

This dataset represents North Atlantic beaches in 2015. The data are part of a larger project, Inventory of Habitat Modifications to Sandy Oceanfront Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) as of 2015: Maine to North Carolina. As of 2015, 1,742.16 miles (2,803.73 kilometers [km]) of sandy shoreline was present between Georgetown, ME, and the North Carolina-South Carolina state boundary, with 1,650.68 miles (2,656.51 km) of sandy beach habitat present and 90.88 miles (146.26 km) where sandy beach habitat was absent seaward of hard stabilization structures, or armor. Massachusetts (458.40 miles or 737.72 km) and North Carolina (322.26 miles or 518.63 km) had the...
