The ecologically-relevant geophysical (ERGo) landforms dataset is a comprehensive classification of landforms based on hillslope position and dominant physical processes that covers most of North America. Four hillslope positions form a natural sequence of topographic units along the catena: ridges/peaks (summits), upper slopes (shoulders), lower slopes (foot slopes), and valley bottoms (toe slopes). The position within each of these hillslopes as a function of solar orientation to reflect how ecological processes (especially soil moisture and evapotranspiration) are influenced by insolation. Also included are very flat (i.e. areas <2°) or very steep (i.e. “cliffs” >50°). We provide these data here at 30 m resolution,...

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...

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:...

Background The lands and waters of the South Atlantic are changing rapidly. Climate change, urban growth, and increasing human demands on resources are reshaping the landscape. While these forces cut across political and jurisdictional boundaries, the conservation community does not have a consistent cross-boundary, cross-organization plan for how to respond. The South Atlantic Conservation Blueprint will be that plan. Potential uses Uses under discussion include: Finding places to pool resources, raising new conservation dollars, guiding infrastructure development, developing conservation incentives, showing how local actions fit into a larger strategy, and locating places to build resilience to major disasters...

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...

Researchers from North Carolina State University and the USGS integrated models of urbanization and vegetation dynamics with the regional climate models to predict vegetation dynamics and assess how landscape change could impact priority species, including North American land birds. This integrated ensemble of models can be used to predict locations where responses to climate change are most likely to occur, expressing results in terms of species persistence to help resource managers understand the long-term sustainability of bird populations.
