A fascinating and detailed look at sixteen communities in Pima County that experienced the boom and bust of the mining industry since the 1800s. Conveyed from a cultural historian's perspective, the stories of these communities are told with a goal of promoting preservation of the remnant railroads, schools, post offices, hotels, saloons, and other artifacts from this chapter of our history in Pima County.
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.
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.
Intended to provide the Board with a historical perspective of regional land use planning in Pima County, some of the tools and actions being used by other communities in growth management, and to provide a framework for future Board policy and direction.
