Pima County is now finalizing the long-awaited Multi-species Conservation Plan, which, if approved by the U.S. Fish and Wildlife Service, will streamline public-sector and private-sector development compliance with the Endangered Species Act while protecting endangered species and their habitats. In the coming months, the public will have a chance to comment on the MSCP through the U.S. Fish and Wildlife Service’s formal public comment process before it goes to the County Board of Supervisors for final adoption.This report reviews the history of the MSCP, its relationship with the award-winning Sonoran Desert Conservation Plan, what benefits the MSCP will bring to the community, and what obligations the County, developers, and the taxpayers will have over time. The report also highlights other benefits of conservation actions undertaken by Pima County, including economic, recreation, and health benefits.
The purpose of this report is to highlight lands acquired with 1997 and 2004 voter-approved bond funds, provide a historical record of Pima County’s land conservation efforts and consider how these properties contribute to Pima County’s long-term vision – the Sonoran Desert Conservation Plan. The report also provides a special feature on the evolution of conservation and land use planning in Pima County.
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.
This report was drafted to facilitate discussion about protection of cultural resources under the Sonoran Desert Conservation Plan. The first part of the report provides an overview of historic preservation in Pima County, while the second part provides analysis and recommendations for improving Pima County's historic preservation policy.
Each year, information is requested from cities, towns, private water companies, and water improvement districts in an effort to summarize and document water conservation activities implemented within Active Management Areas.
The Groundwater Cleanup Task Force has examined various aspects of Arizona's cleanup programs as well as similar programs in other states and on the federal level. Its members have debated these issues in detail, and present this report as a summary of the Task Force's work and recommendations.
The model was developed as a tool to better understand the complex and interdependent stream-aquifer system, and to provide guidance for the management of regional water resources. Water management topics relevant to the Santa Cruz AMA include bi-national water issues and the reliability of water supplies. This model was primarily calibrated over the recent effluent-dominated groundwater flow regime (1997-2002) because of the availability of high quality head, flow and pumping data. Thus, some model boundary conditions calibrated over recent periods may not necessarily be representative of pre-effluent conditions.
Recommends where riparian land acquisitions would be most effective in serving as mitigation that would cover all priority vulnerable species identified in the SDCP. Priority is given to reaches of watercourses.
Since habitat loss and fragmentation by roads and other infrastructure pose major challenges to wildlife movement in these areas, high priority should be given to identifying, preserving, and reconnecting habitat linkages.
