Sonoran Desert Conservation Plan—Priority Vulnerable Species in Pima County
(All of these species are not on the endangered list, but these species have been selected as requiring extra conservation planning.)
"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.
