The habitats of the Southeast Atlantic states range from the mountains and uplands in the Blue Ridge and Piedmont areas in the western portion of this region to the Southeastern and Coastal Plains. Fish habitats in the higher elevation regions are typically fast-moving, clear, coldwater streams originating from seeps and springs, while warmwater rivers of the plains carry more organic material and sediment. This diversity of habitats along a very long period of stable geologic activity produces one of the most diverse assemblages of aquatic species in the nation. The Altamaha, Chattahoochee, Flint, Savannah, Catawba, Pee Dee, Broad, and Neuse are major rivers of the region. There are a large number of dams on waterways...

Partnerships - Atlantic Coastal Fish Habitat Partnership, Eastern Brook Trout Joint Venture, Reservoir Fisheries Habitat Partnership, and Southeast Aquatic Resources Partnership Removed four barriers that opened access to six mile of streams and restored 21 miles of streams to improve habitat for Eastern Brook Trout and other fish species. A shoreline restoration demonstration area was constructed near the U.S. Army Corps of Engineers Visitors Center in North Carolina. Native vegetation was used to stabilize 175’ of shoreline to be used as a showcase for other lakeshore property owners. Planted 0.2 acres of tidal marsh and installed 0.1 acres of oyster reefs in Stump Sound, North Carolina. Also planted 0.15 acres...

Available data for the American Eel (Anguilla rostrata) indicate that, overall, there have been declines in recruitment, population, and escapement during three generations (36 years). A recent report indicated that barriers to migration (dams and weirs), passage through turbines at hydropower dams, habitat degradation or loss, and overharvest were likely the greatest threats by humans across the species’ range. Although eels are able to ascend many smaller barriers, recent studies have documented a tenfold reduction in eel density above each potentially passable barrier. For example, the number of juvenile eels migrating to Lake Ontario passing over hydropower dams fell from 935,000 in 1985 to approximately 8,000...

The Ironcolor Shiner (Notropis chalybaeus) is found in deep pool areas of creeks and small rivers and is often associated with aquatic vegetation. This species needs clear sandy areas for spawning. Populations of Ironcolor Shiner are in decline due to increased turbidity, siltation, and pollution.

The Waccamaw Silverside (Menidia extensa) has a very limited distribution confined to Lake Waccamaw in North Carolina, a lake with neutral pH levels from underlying limestone formations in an area of acidic natural waters. This species is found in large schools and often over dark-colored substrates. Its limited habitat is threatened by nutrient loading caused by the runoff of organic matter and agricultural chemicals.

Relative condition of fish habitat in streams of the Pacific Coast States. Histogram shows percentage of total stream length in each condition class.
The Bering Cisco (Coregonus laurettae) is endemic to Alaska and is present primarily along the State’s west and north coasts. It is known to spawn in only three river systems – the Yukon, Kuskokwim, and Susitna Rivers. Genetic research indicates that each of these populations is distinct. The Bering Cisco has been observed to migrate more than 1,200 miles into freshwater streams to spawn. Unlike salmon, some of these fish survive spawning runs. Since this species is slow-growing but short-lived, it is highly vulnerable to alterations in stream flow or water quality and large-scale environmental disasters.

In the mostly arid Southwestern United States, water availability (hydrology – a key fish habitat process), wildfires, and grazing intensity are important disturbances that are known to have major, negative effects on fish habitats. While this assessment indicated that many of the streams in this region are in good condition, a number of key habitat variables (i.e. water availability, wildlife frequency and intensity, and grazing intensity) could not be directly included in this assessment because national datasets of these disturbances and their measured variable are unavailable. Their absence from this assessment, along with absences of other disturbances, has likely produced an overestimation of habitat condition...

Partnership - Southeast Aquatic Resources Partnership The Harpeth River drains nearly 900 square miles in middle Tennessee and flows through one of the fastest growing regions in the country. It is a state designated Scenic River in Davidson County, within 30 minutes of downtown Nashville. The river is one of the most archeologically and historically significant rivers in the state. However, the project area was listed on the U.S. EPA Section 303(d) list for siltation and habitat alteration, nutrient enrichment and low dissolved oxygen. Low dissolved oxygen was particularly an issue above a 6.2 foot low head dam near Franklin, Tennessee. Dissolved oxygen measurements at this dam were below state standards, and...
The United States is home to more than 3,000 fish species and over 322 million people, and they all depend on the same water. Healthy aquatic resources are vital to the integrity of the United States and essential for sustainable fish populations. Unfortunately, in many places around the United States, fish and the habitats on which they depend are degraded or in decline. Almost 40 percent of the nation’s freshwater fish species are considered at risk or vulnerable to extinction. Habitat loss is the most common cause for extinction of freshwater fish in the United States over the past century, and many saltwater fish are also in decline due to habitat degradation. In 1997, Congress declared that one of the greatest...

The North Atlantic Region of the United States and Canada boasts diverse habitats, from coasts to mountains, that support endemic and rare plant species. However, recent conservation actions and prioritization efforts in this region have neglected to include plants. We have conducted a conservation assessment for vascular plants that occur in the North Atlantic Landscape Conservation Cooperative. Using the best scientific data, we have developed a list of vascular plant species of concern for the region. We have refined the list with the input of Natural Heritage and other regional botanists and experts. For each species, we have determined regional conservation responsibility, developed regional ranks, updated...

Lands within the watersheds of the Great Plains streams that are not used for crops are often used for cattle grazing and hay production. Northern Plains States are one of the nation’s top producers of cattle, which outnumber people almost three to one in North Dakota. Cattle can have direct habitat impacts by trampling stream banks, which destroys beneficial vegetation and increases sedimentation and nutrient loads. Hofmann and Ries (1991) found that livestock increased sediment runoff in North Dakota streams. Schepers and Francis (1982) reported that runoff from a Nebraska cattle farm increased total phosphorus levels in runoff by 37%. In addition, cattle watering ponds, often constructed by diverting streams,...

The Crystal Darter (Crystallaria asprella) requires large, clear-water streams with clean sand and gravel bottoms and moderate to swift currents. It is intolerant of siltation and other forms of pollution from various land use practices. Direct habitat degradation from damming, channelization, and dredging has also reduced habitat for this species. Remaining populations have become isolated from one another by dams and impoundments. The Mississippi River most likely no longer serves as a usable corridor for the Crystal Darter because of the silt load. The isolated local populations are then vulnerable to single destructive events such as toxic chemical spills.
The objective of this project is to integrate observations from multiple image acquisition platforms into a coherent time series of glacier volume changes for a variety of sites in the Pacific Northwest, including South Cascade Glacier and the others in Washington State (e.g., Mt. Olympus, Mt. Rainier, Mt. Baker). Specific objectives include: Enhancing glacier mass balance methodology by incorporating newly derived and reanalyzed geodetic records in the form of Digital Elevation Models and associated Area Altitude Distributions. Estimating regional patterns of glacier mass balance by expanding the spatial density of mass balance measurements and the geographic diversity of monitored glaciers. Understanding hydrologic...
Climate change is expected to result in changes in plant-pollinator interactions, but the severity of these changes is not yet clearly understood. This project will address both spatial and temporal effects of climate change on plant-pollinator interactions by studying butterfly and plant phenology in alpine and subalpine environments of Mount Rainier National Park (MORA). Western Washington University and the National Park Service will collaborate on several project objectives, including conducting field work at multiple meadows at MORA to collect plant and butterfly data, constructing plant phenophase profiles for common forbs, constructing butterfly emergence curves for commonly detected species, developing a...
