This report examines how effectively Pima County’s natural open-space acquisitions have addressed priorities for conserving species’ habitats and landscape features identified in the Sonoran Desert Conservation Plan. The scope of this study is beyond the County's Multi-Species Conservation Plan, which is a subset of the overall Sonoran Desert Conservation Plan.
Letter from Alf Dickenson to Carl T. Hayden about securing mining permits within the park.
Pima County is blessed with a rich and varying record of human settlement over the 11,000 years representing prehistoric, Spanish Colonial, and Mexican-American influences in our history. The County's archaeological site is the building of structure with traditional cultural values and historic landscapes are all nonrenewable cultural resources.
