Description

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.

Description

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?

Description

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

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.

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

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.

Description

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.

This report both updates statistics and perceptions and adds new features. Thus, readers may look at quality of life based on how residents feel or on the trend lines revealed in the numbers. What Matters reports what people think about Greater Phoenix, how they view their own lives, and whether they believe the region is on the right or wrong track. The sections are presented in the order of importance assigned to them by the survey rankings (i.e., Education appears first, Public Safety and Crime second, etc).

What Matters is intended to support decision-making on public issues and to provide a reference for policy makers, civic and business leaders, community activists, and other residents. In response to feedback on previous issues, this edition includes additional indicators for healthcare and more information on higher education. Price and income data have been adjusted for inflation, and more information has been added where appropriate for a fuller picture of trends. Different approaches or completely new sources of data were required in some of this issue’s indicators because of changes in data sources. While every effort was made to choose items that would be stable, there is no way to control for how data are collected or reported over the years. On the whole, however, the 1997 baseline remains intact.
