This report examines how effectively Pima County’s natural open-space acquisitions have addressed priorities for conserving species’ habitats and landscape features identified in the Sonoran Desert Conservation Plan. The scope of this study is beyond the County's Multi-Species Conservation Plan, which is a subset of the overall Sonoran Desert Conservation Plan.
The purpose of this study is to provide the U.S. Fish & Wildlife Service with an analysis that identifies anticipated impacts to each of the covered species and asks the question: How effectively will the County's mitigation lands include the specific habitats of covered species under the Multi-Species Conservation Plan?
Develops the methods for using the National Land Cover Dataset to report change by jurisdictions and land ownership by utilizing an existing dataset. Local GIS-based measures of development based on tax assessor records do not provide direct measures of habitat loss.
Chronicles how the intention to conserve a relic population of Gila topminnow under current resource conditions is generally insufficient. We have let the resource base degrade too far to expect project and site specific responses to stem losses, much less lead to recovery. The Gila topminnow was considered to be among the most common of fishes in the Santa Cruz River system in the early 1940s. Three decades later is was considered endangered; and in another three decades time, its recovery is not foreseeable, given the piecemeal approach to protection efforts.
If one species had to be chosen to preserve and restore, perhaps it should be cottonwood. Cottonwood-willow forests, where they exist and are healthy, indicated the presence of a viable riparian area, which is in turn the key to conserving great proportions of our native species. A reflection of the dire status of our riparian systems is that the Sonoran cottonwood-willow and Sonoran mesquite-cottonwood forests.
Two studies that describe the progress of riparian mapping that is being developed as part of the Sonoran Desert Conservation Plan.
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.
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.
In preparation for new federal legislation that promotes unprecedented levels of comprehensive planning and service integration at state and local levels, an analysis of state issues relevant to comprehensive service delivery is necessary. This paper examines such state issues, with a focus on Arizona's at-risk population, and presents a framework for comprehensive service delivery. It provides the rationale for such service delivery, summarizes the literature on research-based practices, illustrates district approaches to comprehensive service delivery, and sets forth guidelines for developing a comprehensive plan. System components of an effective plan are discussed in detail--student education, parent/family involvement, social/economic services, health services, and professional development. Five general principles underlie success: philosophy, people, processes, promising practices, and partners. Recommendations for developing comprehensive service delivery programs include the following: (1) build on existing information; (2) consolidate knowledge; and (3) think long-term. Contains 11 figures and over 250 references. Appendices contain information on Arizona practitioners' views and an illustration of a side-by-side program analysis.
