The Southern Appalachian Information Node (SAIN) is a collaborative group of public and private partners working to improve access to information related to the biological resources of the Southeast. SAIN provides web-based access to information resources such as research data, expert lists, mapping resources, and educational tools.
SAIN operates with the vision that open access to biological information fosters informed decision-making that can better preserve the integrity of human life and conserve the rich biodiversity of the region. As a geographic node within the NBII (more about the NBII), SAIN functions as a gateway to regional biological information, making it more accessible for policy/management decision-making, research and education.

SAIN Core Service Area
The Southern Appalachian Information Node (SAIN) connects the biological resources of states wthin the core service area of Alabama, Mississippi, Tennessee, and Kentucky.
SAIN General Service Area
Though outside the SAIN core service area, SAIN remains attuned to the biological data and resources of states in the broader Southeast as yet unassigned to a node, including Georgia, Florida, North Carolina and South Carolina.
Land Cover and Ecoregions in the Southeastern U.S.
Within SAIN core service area states, the USGS recognizes the following ecoregions: Piedmont, Southeastern Plains, Blue Ridge, Ridge and Valley, Southwestern Appalachians, Central Appalachians, Western Allegheny Plateau, Interior Plateau, and Mississippi Valley Loess Plain (view ecoregion delineations).
Within the general service area, additional ecoregions are present, including the Southern Coastal Plain, Southern Florida Coastal Plain, and Middle Atlantic Coastal Plain (U.S. Geological Survey, 2006).

Southern Appalachian Fact Sheet
The Southern Appalachian region is one of the most biologically rich areas in the United States. SAIN is a unique source for integrated science including biological, physicochemical, and socio-economic data and information created and coordinated in the region, combining multi-agency information and regional resources to improve productivity, resource management, and sustainable development through the Southern Appalachian Man and the Biosphere (SAMAB) connection and other partners.
