Summary

The ecotone (i.e., edge) between forested and non-forested environments can be a critical aspect of habitat. We grouped land cover types - ecological systems, human land use, and water - (subsequently referred to as map units) into forested, non-forested, and shrubland/woodland land cover types to create unique data layers. These data layers can then be buffered at specified distances to identify species' habitats. Aggregated map units can be compared and contrasted to identify areas of transition between these broad categories. They can also be used to identify core areas or contiguous blocks of similar type (i.e., interior) through buffering. This dataset was derived from the GAP National Land Cover data. Forested map units included [...]

Purpose

Additional data, such as forest/open and woodland/shrubland ecotones, are used in the GAP species modeling process. Forest/open and woodland/shrubland ecotones identified as usable habitat for species is used with this forest/open + woodland/shrubland data to determine habitat suitability in a spatially explicit way.
