Exotic species and their effect on Pima County's aquatic environments have become a priority issue for those involved with managing aquatic ecosystems in eastern Pima County. Invasion of exotic aquatic species presents a major challenge when preserving and restoring native aquatic species in the region.
Report is a review and compilation of existing data on water quality requirements of eight aquatic species. By identifying the water quality requirements of priority vulnerable species of concern, and assessing the quality of water that serves or might serve as potential habitat, we begin to understand which sources will support priority aquatic species identified by the SDCP.

Conservation easements are becoming an important mechanism in Pima County for dealing with matters such as the establishment of mitigation banks and the negotiation of conservation commitments with federal environmental regulatory agencies. This tool will also assist in the implementation of the Ranch Conservation Element of the SDCP. Includes the verbatim proceedings of a workshop on conservation held on August 18, 2001.
On October 27, 2001, Pima County and the Arizona Open Land Trust hosted a workshop on Tax and Estate Tax Planning as part of the Sonoran Desert Conservation Plan's conservation tools workshop series. The verbatim proceedings and materials from this workshop are included.
