Description: The Green Pitcher Plant Potential Habitat dataset is a polygon layer depicting high and low potential habitat locations for Green Pitcher Plant in NC counties that have a USFWS "current" status listing. This model identifies all year-round potential suitable habitat for the species. The habitat for Green Pitcher Plant (Sarracenia oreophila) found in the North Carolina Blue Ridge Province, varies from moderately to steeply sloped seepage bogs (Southern Appalachian Bog-Southern Subtype) and boggy stream banks in North Carolina and Alabama to poorly drained oak and oak-pine flatwoods with a high-water table during the winter months in Georgia. Soils of all known occurrences are generally acidic and derived from sandstones or shales. Soils of the flatwood and seepage bog habitat sites are sandy clays or loams, while those of the stream bank habitat sites are almost pure sand. This carnivorous herb is dependent on some form of disturbance, often periodic fire, to keep its habitat in an early successional stage and reduce competition. Flooding also appears to maintain, and perhaps create, the plant's suitable habitat in its stream bank environment by eliminating competing species.GPP known populations and associated habitats include: 1) Alabama (14 Populations) - 10 extant colonies on streambanks, 1 extant colony in shallow drainage, and 11 extant colonies in seepage bogs; 2) Georgia (1 Population shared w/ North Carolina) – 1 colony in seepage bog; and 3) North Carolina (1 Population shared with Georgia) – 1 colony in seepage bog. Soils associated with these habitats are moist, not subject to regular flooding or saturation. GPP grows away from the wet slough in seepage bogs. Per the Green Pitcher Plant Recovery Plan, streambank colonies are restricted to the Lookout Mountain area.Two element occurrences (EO’s) (1 historic and 1 existing) are listed in North Carolina per Natural Heritage (July 2018). Landcover communities associated with these EO’s include forested/shrub bog and field/pastures.

Use of this dataset for project scoping or screening is merely pre-decisional.
