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.
