Conservation of the Tortolita Alluvial Fan landscape has been promoted by Pima County and Town of Marana over the past two decades. An interdepartmental team was formed to evaluate flood and debris flow hazards and the potential to create an expanded Tortolita Fan Preserve. This report provides an overview of the alluvial fan characteristics and evaluates information on the significance of the biological and cultural resources to determine of the area meets the criteria to create a federal preserve.
Acquisition of this property in northeastern Pima County will prevent development of this property, conserve an important tributary to the San Pedro River, conserve riparian habitat associated with an intermittent stream and springs, and further goals of the Sonoran Desert Conservation Plan and Multi-Species Habitat Conservation Plan. The acquisition is ideally located to expand the emerging reserve system in the San Pedro watershed, which is anchored by the County's A7 Ranch, and complemented by the existing Buehman Canyon Preserve. This report provides preliminary biological and cultural information on this acquisition. Additional biological and cultural resource information will be available after County staff and consultants complete surveys of the property.
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.
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.
This study from the citizens of the Arivaca community proposes to establish an Arivaca Resource Management Zone, where a atwo level management plan integrates the otherwise fragmented land use and water policies of the various regulatory agencies. The Arivaca watershed contains one of the last remaining cienegas and perennial streams in southern Arizona. These unusual water features exist because the area is still in a state of balance, where annual water consumption is less than the natural recharge replenishing the aquifer during years of average precipitation.
Builds upon the "Biological Stress Assessment" through the identification of threats and stressors to watercourses within Pima County. It provides background on technical and water policy matters, describes potential and existing impacts to watercourses within Pima County, suggests options for reducing stressors, and outlines a number of issues for discussion withing each watershed planning unit.
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.
