Without action by Pima County, Rosemont Ranch would probably either be mined or become a residential subdivision over the next several decades. A ranch conservation scenario offers the best outcome for preventing fragmentation of the landscape and conserving the natural and cultural heritage of the area.
This is a non-time opportunity for Pima County to preserve the Bar V Ranch property that has countless benefits. From landscape connectivity for wildlife, to a significant water source for Cienega Creek and the Tucson Basin, to important riparian habitat crucial for the survival of several vulnerable species.
Pima Association of Governments has worked with County staff for over two years on a series of riparian and water resource studies related to the SDCP and Comprehensive Land Use Plan. The three studies found within this document represent the final versions of (1) Water Quality in Pima County; (2) Water Quality of Priority Streams in Pima County; and (3) Water Quality Requirements of Native Aquatic Species in Pima County.
To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers were prepared. In Pima County, ranching is uniquely able to preserve the integrity of vast tracts of connected and unfragmented open space and wildlife habitat. This study reviews the effect of five alternative permit strategies on the County's ability to preserve unfragmented landscapes through conserving ranch lands.
To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers is being published. This study discusses water resources in the context of the alternatives being considered to date.
Provides a snapshot of past and current conditions, and represents the very best of collaborative efforts between the expert community and County staff. This study was made possible by a gift from Dr. Wendell Minckley of a database that provided information about all known surveys of native fish within Pima County, including the species, river basin, drainage, date, number of specimens collected, collector, museum catalogue number, citations, locality, and any comments made.
Arizona's fish story begins in 1904 with the publication of Morton Chambrlain's "Survey of Arizona Fishes", the first detailed study by an aquatic biologist of the area. He was able to count sixteen native species in Arizona. Today more than half are either extinct or listed as threatened or endangered, and most of the rest are considered to be imperiled. In Pima County, we count more extirpated native fish than remaining residents. The story, absent a fairly dramatic change in circumstances, will end with the extirpation or extinction of all native fish in the region. This report provides an opportunity to change the circumstances of aquatic and riparian systems in eastern Pima County.
A companion to the Preliminary Ranch Conservation Element, this report brings together leaders in the area of ranch conservation and compiles their expert writings on ecological and economic sustainability in ranching.
Through the conservation of ranchland in eastern Pima County, the metropolitan urban boundary is better defined, vast landscapes of open space retain their integrity and the heritage and culture of the West is preserved.
By including ranch lands as a landscape form worthy of protection and preservation, Pima County formalized its commitment to keep ranchers ranching as a way of achieving multiple community goals, including conserving natural and cultural resources, preserving open spaces, and defining urban form.
