Provides an inventory of infrastructure resources in the Tucson Mountains / Avra Valley subregion of Pima County.
This study by DR. Philip Rosen stands as one of the most impressive, given the scope of the author's knowledge, and it is one of the most ingenious, given the proposed concepts for restoration and protection of native fish and frogs within the urban Tucson Basin.
Provides a brief summary of a compilation of resource investigations that have been submitted so far, to help develop the SDCP within the watershed planning area of the Avra Valley. The report also includes a number of proposals related to the Ironwood Preserve.
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.
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.
