General information
Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site.
MLRA notes
Major Land Resource Area (MLRA): 130B–Southern Blue Ridge
This MLRA is in North Carolina (51 percent), Tennessee (18 percent), Georgia (17 percent), Virginia (10 percent), and South Carolina (4 percent). It makes up about 16,080 square miles (41,665 square kilometers). It is locally known as the Southern Appalachians. It includes Lenoir, Morganton, Marion, Hendersonville, Waynesville, and Asheville, North Carolina; Gatlinburg, Tennessee; Damascus and Galax, Virginia; Walhalla, South Carolina; and Cleveland, Dahlonega, and Ellijay, Georgia. Interstate 40 crosses the parts of the area in Tennessee and North Carolina. Interstate 77 crosses the part in Virginia. Many national forests are in the area, including the Jefferson, Cherokee, Nantahala, Pisgah, and Chattahoochee National Forests. The Appalachian Trail begins on Springer Mountain in Georgia, near Amicalola State Park. The Great Smoky Mountains National Park is in this MLRA. The Mount Rogers National Recreation Area is in the part of the MLRA in Virginia. The Cherokee Indian Reservation is west of Waynesville, North Carolina.
Classification relationships
This ecosite is found in mountians in MLRA 130B: Southern Blue Ridge
This is a complex system that encompasses a matrix of co-occurring vegetation communities. Data and maps produced by the SE GAP Analysis Project were queried (USGS 2001). At the most detailed level natural vegetation is represented by NatureServe's Ecological System classification (NatureServe 2017). Data has been cross-walked with NVC classification levels (Class, Subclass, Formation, Division, Macrogroup, Ecological System). The classification approach used was the International Terrestrial Ecological Systems Classification (ITESC) (NatureServe 2007 and White 2003). Ecological Systems were cross-checked with the Vegetation Classification System developed for the Great Smoky Mountains National Park (GRSM) in 2009.
Ecological site concept
This Provisional Ecological Site (PES) occurs on nearly level to gently sloping floodplains in the southern Blue Ridge mountains. Slope ranges from 0 – 3%. Soils are classified as hydric. Land-use is variable. A good deal of this site has been cleared, drained and used for cultivated crops, pasture, and hay. Much of the Nikwasi series, included in this PES, is in idle open land that was cleared for cropland but abandoned because of wetness and flooding. These areas have come back in alders, sedges, rushes, and weeds. This PES is partially developed/open space. Where forested, common trees are yellow poplar, sycamore, red maple, yellow birch, river birch, eastern hemlock and in some places, pine species (pitch pine, shortleaf pine, Virginia pine). A few areas have been planted to eastern white pine. Rhododendron is a common understory plant and can influence soil formation in places, such as the hanging coves of the Great Smoky Mountains National Park (GRSM) where Wesser soils are mapped. These areas are also considered critical habitat for amphibians, especially salamanders. Drainage class is the primary ecological driver in this system.
