Sonoran Desert Conservation Plan
(Not all these species are on the national endangered species list, but these species have been selected as requiring extra conservation planning.)
“Pima County is blessed with some of the highest diversity of plants and animals in the continental United States, but this amazing diversity has increasingly been threatened by land-use impacts. Though experts had warned of (and documented) declines of a number of species, it was the listing of the cactus ferruginous pygmy owl as an Endangered species in 1997 that put a spotlight on the impacts that development can have on a species. The Sonoran Desert Conservation Plan (SDCP) had its roots in the owl’s listing and though many other elements of the SDCP focused on a suite of environmental and cultural resources, species protection remains a focus of County actions and activities every day.” See the Sonoran Desert Conservation Plan page for more information.
