These data identify the areas where final critical habitat has been
mapped by the USFWS for invertebrate species. These data were compiled
by the Conservation Biology Institute (CBI) from a series of individual
shapefiles published by the USFWS (http://criticalhabitat.fws.gov/). 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. This particular dataset contains the fish species
critical habitat areas that are represented by polygons. Critical
habitat represented by lines are contained in a separate dataset.
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/).
This file reflects available data
through April 2008.
