Fresh and Saltwater Connectivity This layer was one of the old South Atlantic LCC indicators in the waterscapes ecosystem. It was an index of dams preventing fish migration between rivers and the ocean. Fresh and saltwater connectivity was not performing well as an indicator and could not be used in Blueprint 2.0. This indicator was replaced in Blueprint 2.1 with a new migratory fish connectivity indicator. Reason for Selection Barriers to connectivity between rivers/streams and the ocean can strongly impact diadromous fish and alter natural movement of sediments, are easy to monitor and model, and are widely used and understood by diverse partners. Input Data Southeast Aquatic Connectivity Assessment Project:...

Salt marshes classification of the South Atlantic Landscape Conservation Cooperative geography covers the northern Outer Banks (and extreme southeastern Virginia, Back Bay area) south through NC, SC, and Georgia to approximately Sapelo Island. The marsh classification is derived from Landsat 8 OLI imagery acquired in May 14-19, 2014. This georeferenced imagery was atmospherically corrected, mosaicked, and water masked prior to deriving a set of three Normalize Difference Indices (NDX) bands: Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI) and Normalized Difference Soil Index (NDSI). Prospective salt marshes and associated tidal non-forested wetlands were classified using object-oriented...

South Atlantic LCC
This layer was created from the 2015 LCC Network Areas dataset for the purpose of depicting the working area of the South Atlantic LCC geographic area. This area differs from the actual geographic area in that it includes portions of the Apalachicola, Chattahoochee and Flint (ACF) River Basins. The ACF is a special integration zone between the Gulf Coastal Plains and Ozarks LCC and the South Atlantic LCC. It also highights the St. Johns basin as a special integration zone between the Peninsular Florida LCC and the South Atlantic LCC. Landscape Conservation Cooperatives (LCCs) are public-private partnerships composed of states, tribes, federal agencies, non-governmental organizations, universities, international...
