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...

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.

The southeastern states contain the rapidly growing urban centers of Atlanta, Greenville, Columbia, Charlotte, and Winston-Salem/Raleigh with suburban corridors between them. In these cities and the surrounding suburbs, large areas of impervious surfaces replace natural streamside habitat, increase pollution and sedimentation, and alter water flow (hydrology). In this 2015 assessment, land cover type was estimated to be a major risk factor for about one-third of the estuaries of the Southeastern states. The United States Department of Agriculture reports that from 1982 to 2012 over 2.6 million acres of rural land in Georgia was developed. Development in North Carolina was almost as high, while South Carolina lost...

A. Pervasive disturbances: The most common disturbances based on total stream length in a given region. Top five overall most pervasive disturbances to all stream reaches, regardless of stream size and across all spatial scales (ranked highest first): Impervious surface cover Population density Low intensity urban land use Road length density Downstream dam density Top three most pervasive disturbances to creeks (watersheds <100 km 2 in area) across all spatial scales: Impervious surface cover Low intensity urban land use Population density Top three most pervasive disturbances to rivers (watersheds >100 km 2 in area) across all spatial scales: Upstream dam density Pasture and hay land use Population...

Since European settlement, the wide coastal plain of the Southeast Atlantic states has been used for large agricultural operations producing soybeans, corn, cotton, peanuts, tobacco, and many other agricultural products. Recently, farmers have intensively planted more acreage with soybeans and corn, which is in part due to the biofuel demand. Increasing use of irrigation for these row crops has changed water flow (hydrology) in many of the region’s streams. Intensive hog and chicken farming have expanded as well. Improperly managed runoff from farms contributes excess sediments and nutrients to streams, which interferes with fish spawning, can lead to potentially harmful algal blooms, and can cause fish kills from...

Partnership - Southeast Aquatic Resources Partnership Dams and man-made barriers pose to impeding the movement of fish and blocking fish from their spawning grounds and habitat connectivity is listed as a top priority of the Southeast Aquatic Habitat Plan, the strategic plan of the Southeast Aquatic Resources Partnership (SARP). To help address this issue, SARP, together with the Nature Conservancy (TNC) has completed a large scale assessment of dams in the Southeastern United States. The Southeast Aquatic Connectivity Assessment Project ( SEACAP), funded by the South Atlantic Landscape Conservation Cooperative (SALCC), supports planners and managers in their efforts to target fish passage and other aquatic...

The Pinewoods Darter (Etheostoma mariae) is native to the Little Peedee River system in the Carolina Sandhills area where it is found in smaller, swift-flowing creeks with gravel bottoms and vegetation. This area is becoming increasingly altered by residential development, agriculture, lumbering, and damming of headwater streams, typically for golf course development. Additionally, the reintroduction and rapid expansion of beavers in this drainage is converting some of the critical flowing streams to small impoundments.

The Shoal Bass (Micropterus cataractae) is one of a number of unique, lesser-known native bass species that have very restricted distributions. Juveniles and adults of this species require riffle and pool habitat with clean gravel substrate for spawning. Although the exact mechanism of population declines for this species has not been proven, the Apalachicola-Chattahoochee-Flint basin where Shoal Bass occur is the second-most impounded basin east of the Mississippi River, with more than 1,400 impoundments. The dams have fragmented and destroyed habitats through inundation, altered water flows, changed temperature regimes, and allowed the establishment of similar competing non-native basses, such as the Spotted...

Over 10,000 dams impound rivers and streams in the three Southeast Atlantic states. North Carolina has over 5,600 dams and barriers on 17,000 stream miles, many of which are old and obsolete structures. There is an average of one barrier structure every three miles. The state also ranks second in the number of high-hazard dams, which can negatively affect the safety of the citizens of North Carolina and aquatic species. These dams impede movements of many native river resident species, such as Brook Trout and Shoal Bass, but also restrict migrations of marine fish that rely on rivers for various life stages, including Striped Bass, Atlantic Sturgeon, American Shad, American Eels, and river herring. In many cases,...

Partnership - Southeast Aquatic Resources Partnership Eleven of the fourteen species, subspecies, and other unique forms of black bass are found in the southeastern U.S. and nowhere else in the world. Several undescribed species and subspecies of black bass are also found in the region and almost all are in need of conservation measures to prevent them from becoming imperiled. In an effort to focus and coordinate actions to secure healthy, fishable populations of the diversity of black basses, the Southeastern Aquatic Restoration Partnership (SARP) led the development of the Native Black Bass Initiative (NBBI). The NBBI is guided by a 10-year, $30 million plan that was assembled in partnership with the National...

Invasive predatory Flathead Catfish are causing population declines of native Redbreast Sunfish and species of Bullhead and Madtom catfishes in Georgia, North Carolina, and South Carolina, along with issues for other migratory species, such as Alewife, Blueback Herring, and American Shad. The Georgia Department of Natural Resources maintains a program to control the population in the Satilla River, and North and South Carolina State fishery agencies have similar efforts and concerns. The Savannah River Basin is home to more than 75 species of rare plants and animals and 110 fish species. There are 18 Federally listed fish species in the Savannah River Basin—five are Federally listed as threatened and 13 are Federally...
