These data identify the areas where final critical habitat has been
mapped by the USFWS for fish 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 lines. Critical habitat represented by polygons
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.
