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.

We have an opportunity now that we have not had in the past 25 years to develop some comprehensive planning so that we can continue to enjoy the environmental amenities that make it so nice to live in Tucson. These species include not only the common one that we live with on a day to day basis, but also some of the rare species that most of us are not lucky enough to see (but still care about preserving).
