The Western Governors’ Association (WGA) sponsored an assessment of crucial habitats which will be used for the evaluation of landscape-scale energy, land use, and transportation projects throughout the western United States. The main product of the WGA’s assessment is an easily accessible online system of maps displaying crucial habitats and corridors known as the Crucial Habitat Assessment Tool (CHAT; http://www.westgovchat.org/).Crucial habitats were based on factors such as species of concern, species of economic and recreational importance, special ecological systems and habitat types, habitat corridors, native species richness, and ecological integrity (i.e., unfragmented habitats). All of these factors are...

This data set depicts federal lands having restrictions on access or activities -- that is, lands mangaed by the National Park Service, Defense Department, or Energy Department -- in western North America. The data set was created by reformatting and merging state- and province-based ownership data layers originally acquired from diverse sources (including state GAP programs, USBLM state offices and other sources). For each original dataset 3 additional fields, "Pub_Pvt", "CA_OWN", and "SOURCE" were added and populated based on the specific ownership information contained in the source data. The original coverages were then merged based on the "CA_OWN" field. Finally, NPS, DOD, and DOE lands were selected out of...
