The Altar Valley Conservation Alliance is a collaborative conservation organization founded in 1995, and incorporated as a 501(c)3 not-for-profit organization. Just southwest of Tucson, Arizona, the Altar Valley comprises approximately 610,000 acres of Sonoran desert grassland, some of the most biologically rich and ecologically threatened biotic communities in the world. Private ranches work side by side with federal, state and local agencies to manage the valley, which is the largest unfragmented watershed in Pima County, outside of the Tohono O’odham Nation to the west. This collection is an archive of reports and other documents specific to Alliance activities.

Pima County Government
While finalizing the Multi-species Conservation Plan (MSCP), Pima County created this 18 page summary to enhance the public's understanding of the extensive plan. The MSCP was created to simplify public sector development compliance with the Endangered Species Act while continuing to protect endangered species and their habitat. This document also provides a background on the MSCP and describes some of its anticipated benefits.
