Terrestrial Records
-
The karst map provides the basic template for analyzing the distribution of cave species. Almost without exception, all caves occur within the karst areas. There were a few records of cave-dwelling species from outside karst areas (mostly springs) but the data was trimmed to fit within the karst areas, with a 1 km buffer to allow for errors in georeferencing). This map displays the aquatic records within karst areas in the Appalachian region.
