Describes methods that are used in order to prepare reserve design alternatives in the area of biological conservation. The report also provides a brief history of reserve design theory, and demonstrates how the principles of biological reserve design have been extended to the other Elements of the Sonoran Desert conservation plan.
Overview of the Draft Preliminary Sonoran Desert Conservation Plan: Sonoran Desert Conservation Plan
A review and explanation of aspects of the first two years of the planning process, written for the general public to describe in non-technical terms both the procedural and substantive aspects of the conservation planning effort.
An assessment of the problems that are presented by non-native and introduced species in maintaining native species and natural systems. Divided into two major sections, the study covers representative ecosystems in Pima County as well as representative species that have a negative impact on native species.
This preliminary plan serves as a summary of technical and scientific information gathered to date and is intended to frame a broad range of options so that future public participation provides the Board with relevant information that can form the basis of the final plan.
Pima County Department of Transportation's Technical Services Division maintains GIS hardware, software, and databases with skilled personnel and has applied TIS technology to the SDCP, adapting, creating or acquiring over 1000 data layers for use in the Plan. Metadata has been developed for some of these layers.
Provides a brief update on the SDCP in the areas of research, education and community participation, and intergovernmental cooperation.
A companion to the "Importance of Conserving Resources in the CIenega Creek Watershed" document and provides a focus on Altar Valley. This report includes detailed investigations into the historic conditions of the watershed, current rangeland conditions of biotic communities, and the environmental impact of a potential floodplain project.
Builds from the June 2000 document (Priority Vulnerable Species) by essentially translating written details of each species' natural and biological history to the geographic information system, where a computer survey of the landscape can take place much faster than surveys and expeditions in the field.
Provides a brief summary of some of the resource issues that make the Cienega Creek watershed vital to the overall success of the SDCP, and includes recommendations for conserving land within the watershed.
