These biophysical data layers were integrated with current vegetation layers to develop generalized successional pathway diagrams. Expert regional panels refined the PNV map based on these successional pathways. Purpose: Originally, these coarse-scale data were developed for national-level planning. Specifically, we used this data set in the Sage-grouse Conservation Assessment. Supplemental_Information: Kuchler (1964) defined potential natural vegetation as "the vegetation that would exist today if man were removed from the scene and if the plant succession after his removal were telescoped into a single moment." The time compression eliminates the effects of future climatic fluctuations, while the effects of man's earlier activities are permitted to stand.
