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.
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.
To prevent unwanted urban sprawl and unregulated development, it is most important that Pima County encourage and retain viable ranches. Ranching is a significant land use that has served to protect our natural open space, and it continues to be an important traditional industry that has shaped the rural landscape.
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.
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.
The pygmy-owl was listed as endangered in 1997, but notice of the potential listing dates back to 1989. This paper provides a report on pygmy-owl research and rulings, evaluates whether the efforts of the community are leading to the recovery, downlisting and delisting of the pygmy-owl, and concludes that with the exception of valuable in-kind services of the Arizona Game and Fish Department pygmy-owl biologist, meaningful financial support for research and conservation planning efforts has been limited to federal and County contributions.
The purpose of this report is to represent the different types of land stewardship in Pima County in a digital Geographic Information System cover and to update the evaluation of vegetative communities relative to these classes. A previous evaluation suggested that 24 percent of Pima County is in a reserve of some kind; the current evaluation now suggests 26.5 percent.
This memorandum analyzed fourteen mapping efforts that have taken place in the past decades, or that are ongoing. About half of these initiatives created data that is useful for a basemap for regional bio-planning purposes. Analysis provides advice about how future research and mapping initiatives within Pima County can gather data in a more effective manner.
