A preliminary analysis that has been drafted in conjunction with participating federal agencies. Land managing entities provided information and later a detailed review of fact sheets that summarize each reserve in terms of its size, ownership, authorizing documents, land use activities, priority vulnerable species, exotic and non-native species, baseline information, GAP status, acquisitions, management plans, research, monitoring and recovery programs. The study proposes eight Reserve Management Areas that include land managers who could work together across administrative boundaries.

Describes methods that are used in order to prepare reserve design alternatives in the area of biological conservation. The report also provides a brief history of reserve design theory, and demonstrates how the principles of biological reserve design have been extended to the other Elements of the Sonoran Desert conservation plan.

Status reports containing more detailed information about the priority conservation areas of each species. The first summary provides a view from the technical perspective of how the biological reserve has been assembled. The second summary provides a view from the historical and process perspective of how the biological reserve has been assembled.

The cornerstone of any habitat conservation plan is the establishment of a set of reserves that are ultimately managed to preserve or enhance populations of a particular species or suite of species. Also, with any priority species in a particular region there are geographic areas that are much more important to the species than others. Identifying those areas is an important part of the planning process and a required activity to help assure that the best habitat areas for each species are identified and targeted for inclusion within the reserve system.

Provides a brief analysis of the legal and financial feasibility of the March 16, 2000 proposal, as well as a comparative analysis of (1) the conservation value, (2) the level of cultural resource protection, and (3) the fiscal impact of the proposal as measured against other development projects and against the various alternatives that might be exercised by the landowner.

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.
