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.
The Governor’s Executive Order in 2007 directed the Arizona Invasive Species Advisory Council to develop an invasive species management plan by June 30, 2008. This plan is based upon the framework recommended in the initial AISAC report and focused on five strategic concepts: Leadership and Coordination, Research and Information Management, Anticipation and Outreach, Control and Management, and Funding. In developing the plan, fifteen objectives and sixty-three recommendations were established to address invasive species needs in Arizona.
Four maps showing vacant parcels, improvements on 5+ acres outside the Eastern Pima County Conservation Lands System. Map 1: Less than $10,000 -- map 2: Less than 1$15,000 -- map 3: Less than $20,000 -- map 4: Less than $25,000.
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.
To facilitate discussion about which species might be considered for protection, a series of in-depth interviews were conducted with members of the local science community who have expertise in the areas of birds, fish, invertebrates, mammals, plants and plant communities, and reptiles and amphibians.
Compiles information on plants and animals that are already recognized by the federal government as imperiled species, species which have been extirpated, and a much larger number of species that are in decline either locally or nationally. Descriptions of status, location, distribution, and habitat needs are presented for each species proposed. The report also considers vegetative communities, their history of decline and modification, and recommends priorities for their protection.
Summarizes four documents that reflect some of the work that Pima County and Department of Interior staff, along with the science and Geographic Information Systems technical teams, have created to develop the biological component of the Sonoran Desert Conservation Plan.
Identifies key potential threats and stressors to vulnerable species in Pima County, and to the biological and hydrological resources that support these species. Emphasis has been placed on identifying the specific components of past, existing, and proposed land and water uses that pose the greatest potential threats over the next 30 years to focal species and special habitats, plant associations, and communities.
Two studies that describe the progress of riparian mapping that is being developed as part of the Sonoran Desert Conservation Plan.
Mr. Proudfoot, the leading pygmy-owl biologist in the United States, has worked for the last two years to gather and analyze the data that allows us to address issues regarding the genetic viability of ferruginous pygmy-owls in Arizona and to establish a framework for future management efforts. The two major questions addressed are (1) do populations of concern lack genetic variation relative to putative healthy populations, and (2) how unique are geographically distinct populations within a species of special concern?
