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.

Provides an overview of the issues related to monitoring the 36 species proposed for coverage under the forthcoming Section 10 permit to the United States Fish and Wildlife Service. By integrating the requirements for MSCP compliance and effectiveness monitoring with the challenges inherent in single-species monitoring, this document seeks a balance between species-specific monitoring and other habitat, ecosystem and threats-based measures (parameters). By designing such a program, Pima County will be in a better position to anticipate and adjust management actions for the conservation of covered species and the ecosystems that support them.

What has been developed in Orange and San Diego County, Calif. are blueprints for other urbanizing communities committed to striking a balance between growth and development and environmental quality and its notion of livability. These plans successfully put in place conservation measures unprecedented in their scope and breadth and yet do so without compromising the economic vitality of the region.

With the passage of the Federal Endangered Species Act in 1973, the stage was set for a confrontation between urban development and the provisions of Federal Law. Language was amended to the Act that established standards that a plan would have to meet before the Fish and Wildlife Service could approve it and issue a permit for the take of a listed species. In those jurisdictions that have adopted this approach, conservation of natural resources is no longer an afterthought but a major element that has to be considered during the regular land use permitting process.

To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers have been written. This study presents a brief look at outdoor recreation issues and describes the impacts of five alternative permit strategies might have on the County's ability to maintain recreation opportunities.

Survey results for wetland plant communities of the Agua Caliente Park and nearby La Cebadilla property. The study also documented the presence or absence of Huachuca water umbel, a plant listed as endangered in Pima County. By studying the wetland plants of the La Cebadilla property, and through historic herbarium collections, the biologist found that several plants still present at La Cebadilla were known to be present at the Agua Caliente Ranch at the turn of the century.

Describes the relation of the current and proposed system of mountain parks and preserves to the ongoing multi-species conservation planning process. Business interests will be able to pursue land uses which impact habitat, so long as defined conservation standards are met. This report simply frames planning possibilities by outlining the known potential of twelve park and preserve areas in eastern Pima County.
