The most complete version assembled of the story of the 56 plants and animals in Pima County that are in need of protection under the SDCP. Three years ago when discussions began about creating a multi-species protection plan, there was no comprehensive inventory of the resource base.
Recommends which of the over 100 vulnerable species of concern in Pima County should be considered for coverage under the County's future permit and further analyze approximately 50 animals and plants as potentially covered species under the multi-species conservation plan.
Provides a detailed description of plants and animals that are being considered as potentially covered under the multi-species program, organized by taxonomic group. Two strong themes emerge when this compilation of species accounts is read together: one is the enormous importance of aquatic and riparian-based habitats to the majority of priority vulnerable species, and the other is the very bleak biological status of the riparian system.
