Invasions by non-native species cause serious problems in many parts of Pima County. It will benefit from adopting policies and increasing coordination with government and non-profit groups to deal effectively with invasive species.
A restoration effort of the San Pedro River to restore sacaton grassland, riparian trees and mesquite to about half the 50 acres of fallow agricultural fields at the Bingham Cienega. The overriding goals were to (1) establish a diversity of riparian habitats in the fields which in turn will support a greater number of invertebrate, reptile, mammal and bird species; and (2) develop practical techniques for promoting establishment of native plants that require little or no irrigation.
Describes a comprehensive regional policy direction to achieve meaningful riparian restoration necessary for endangered species compliance and the basic relation of water policy to conservation planning.
Drafted to facilitate discussion of implementation options. The concepts will assist in future planning and implementation discussions that take place as the Sonoran Desert Conservation Plan is finalized. A purchase of development rights program could assist in the funding of open space lands that contribute to the overall conservation reserve.
A companion to the Preliminary Ranch Conservation Element, this report brings together leaders in the area of ranch conservation and compiles their expert writings on ecological and economic sustainability in ranching.
Through the conservation of ranchland in eastern Pima County, the metropolitan urban boundary is better defined, vast landscapes of open space retain their integrity and the heritage and culture of the West is preserved.
Pima County assembled a comprehensive land cover map for the the SDCP and in the process of doing so, identified the strengths and weaknesses of prior mapping efforts. In order to combine the best aspects of past efforts, a common language had to be established among the classification systems.
This memorandum analyzed fourteen mapping efforts that have taken place in the past decades, or that are ongoing. About half of these initiatives created data that is useful for a basemap for regional bio-planning purposes. Analysis provides advice about how future research and mapping initiatives within Pima County can gather data in a more effective manner.
Brings together and updates prior anlayses of the riparian restoration element of the SDCP to include not only the considerations of the Endangered Species Act, but also the Clean Water Act. The report defines the scope of environmental and legal issues, and describes a method for further integrating efforts to address environmental and regulatory issues.
