These data identify the areas where final critical habitat has been
mapped by the USFWS for bird species as well as key greater sage-grouse
habitat areas identified by the BLM. These data were compiled by the
Conservation Biology Institute (CBI) from a series of individual
shapefiles published by the USFWS (http://criticalhabitat.fws.gov/) and
provided by Alan Ager (USFS). For more information on the process for
mapping the critical habitat for each species, please see the metadata
for each species listed on the USFWS web site. Critical habitat
designations have not been made for all listed endangered species.
Where critical habitat has been mapped, this dataset only contains those
species for which GIS datasets have been made publicly available. Other
critical habitat maps exist for some species in non-GIS formats only,
and are therefore not represented within this dataset. These data are
to be considered approximate only, and should not be used for legal
purposes. For legal use, please refer to the Federal Register documents
for each species (see http://criticalhabitat.fws.gov/).
