Compiles water quality data for the streams that have been identified as priorities and assesses land uses and potential pollution sources that might impact the water quality of the highest priority aquatic habitats.
The most complete version assembled of the story of the 56 plants and animals in Pima County that are in need of protection under the SDCP. Three years ago when discussions began about creating a multi-species protection plan, there was no comprehensive inventory of the resource base.
Surveys were conducted for Huachuca water umbel at the Cienega Creek Natural Preserve, the Bingham Cienega Preserve, and the La Cebadilla property. Because the plant was detected in sites that are further north and at lower elevations than previously considered, the study recommends that assumptions regarding the potential presence of the species throughout Pima County should be re-examined.
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.
By including ranch lands as a landscape form worthy of protection and preservation, Pima County formalized its commitment to keep ranchers ranching as a way of achieving multiple community goals, including conserving natural and cultural resources, preserving open spaces, and defining urban form.
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.
To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers is being published. This paper discusses fire management in the context of the alternatives being considered to date.

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.
The basic questions addressed in the environmental justice study are whether low income and/or minority neighborhoods are or have been disproportionately affected by the impacts of pollutants in air or water; by land use decisions; financially by environmentally-related governmental decisions.
