Priority Vulnerable Species
are species that are being considered and analyzed as
potentially covered species under the multi-species habitat conservation
plan. These species were chosen through a process of scientific review
of over 100 species that are already listed as Threatened or Endangered
or recognized by the federal government as imperiled, extirpated
species, and a much larger number of species that are in decline, and
potentially on the way toward ESA listing.
