Pima County is now finalizing the long-awaited Multi-species Conservation Plan, which, if approved by the U.S. Fish and Wildlife Service, will streamline public-sector and private-sector development compliance with the Endangered Species Act while protecting endangered species and their habitats. In the coming months, the public will have a chance to comment on the MSCP through the U.S. Fish and Wildlife Service’s formal public comment process before it goes to the County Board of Supervisors for final adoption.This report reviews the history of the MSCP, its relationship with the award-winning Sonoran Desert Conservation Plan, what benefits the MSCP will bring to the community, and what obligations the County, developers, and the taxpayers will have over time. The report also highlights other benefits of conservation actions undertaken by Pima County, including economic, recreation, and health benefits.

The purpose of this report is to highlight lands acquired with 1997 and 2004 voter-approved bond funds, provide a historical record of Pima County’s land conservation efforts and consider how these properties contribute to Pima County’s long-term vision – the Sonoran Desert Conservation Plan. The report also provides a special feature on the evolution of conservation and land use planning in Pima County.
