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.
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.
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.
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.
Provides a brief update on the SDCP in the areas of research, education and community participation, and intergovernmental cooperation.
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.
On the County's behalf, the Arizona Open Land Trust has entered into two purchase agreements for the Buckelew Farms property. Under this conservation acquisition proposal, farming would continue in the areas currently farmed, grazing would continue on a seasonal basis, and the popular annual pumpkin festival would continue. However, the County and the Buckelew's would work together to enhance opportunities for wildlife habitat on the farm and grazing lands.
The Augusta Resources Corporation proposes to construct the Rosemont Mine project in the northern Santa Rita Mountains. This report is a reconnaissance analysis of the conceptual flow and water balance in the area. The conceptual flow model for the area is based on topography, geology and precipitation and identifies the likely flow paths in the watershed and aquifer system. The water balance includes estimates of recharge to and groundwater flow from the area; there is no evapotranspiration discharge from the regional groundwater.
Conservation of the Tortolita Alluvial Fan landscape has been promoted by Pima County and Town of Marana over the past two decades. An interdepartmental team was formed to evaluate flood and debris flow hazards and the potential to create an expanded Tortolita Fan Preserve. This report provides an overview of the alluvial fan characteristics and evaluates information on the significance of the biological and cultural resources to determine of the area meets the criteria to create a federal preserve.
Stream flow disappearance due to groundwater pumping, floodplain development, and habitat loss due to erosion have significantly altered the biologically rich and diverse riparian corridors of eastern Pima County. Today, there are new opportunities to recreate our watercourses as a gathering place for people and wildlife.
