Stream flow disappearance due to groundwater pumping, floodplain development, and habitat loss due to erosion have significantly altered the biologically rich and diverse riparian corridors of eastern Pima County. Today, there are new opportunities to recreate our watercourses as a gathering place for people and wildlife.
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.
On the County's behalf, the Arizona Open Land Trust has entered into two purchase agreements for the Buckelew Farms property. Under this conservation acquisition proposal, farming would continue in the areas currently farmed, grazing would continue on a seasonal basis, and the popular annual pumpkin festival would continue. However, the County and the Buckelew's would work together to enhance opportunities for wildlife habitat on the farm and grazing lands.
The spread of invasive species creates serious environmental problems as well as economic hazards for residents and will hamper implementation of parts of the SDCP.
Pima County in partnership with the Arizona Open Land Trust has the opportunity to purchase 500 acres of land in fee simple from the Buckelews at a per acre price of $1,800, for a total of $900,000 plus closing costs.
Pima County's grant proposal for the 640.4 acre in-holding in the Ironwood Forest National Monument known as Lord's Ranch was selected by the U.S. Department of the Interior.
Compares conservation plans from: City of Austin and Travis County, Texas -- Clark County, Nevada -- Wisconsin statewide -- San Diego, California -- Coachella Valley, California -- Orange County, California -- Volusia County, Florida.
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.
Demonstrates that an effort to protect only listed species would lead to a reserve that was closer to the urbanizing areas of Tucson, and therefore more expensive. The Listed Species Reserve is also one that makes a call on more non-federal land. By limiting the focus of the reserve to listed species, the broader and long term benefits are lost, and trade-offs of high potential habitat are not based on such comprehensive biological principles.
