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.
A companion to the study issued on July 5, 2000 entitled 'Cactus Ferruginous Pygmy-Owl Investigations in Pima County.' The major objective was to determine whether pygmy-owls chose nest sites or perch trees with characteristics that differ from other available sites within a nesting territory.
Pima County contracted with Arizona Game and Fish Department to conduct telemetry analysis and gather information that would lead to effective conservation and recovery initiatives for the cactus ferruginous pygmy-owl. During 1997, banded birds were monitored. Beginning in 1998 and during 1999, pygmy-owls were radio-marked with backpack transmitters and followed on foot or by vehicle.
