This raster dataset has been created using the NImportant Mammal AreasN as originated by the Environmental Resources Research Institute of Pennsylvania State University. All areas designated as important mammal areas were assigned a conservation value of 3. Conservation values were determined by experts gathered by Natural Lands Trust through SmartConservation. This data set is one of several that have been combined to create an overall terrestrial resources conservation value raster for the Central Appalachian Forest Ecoregion. Therefore the values were determined as a relative rank, comparable in value only to the other input terrestrial resources data. Conservation value ranges from 1 - 10 with 10 being the highest value.
