An introduction to the impact of conservation alternatives on air quality which will be integrated into the land use and conservation plans. The air quality study is summarized in this memorandum.

Potential funding sources and future legislative considerations are briefly discussed.
To facilitate development of the Environmental Impact Statement which must accompany the Section 10 multi-species conservation proposal, a series of issue papers were prepared. In Pima County, ranching is uniquely able to preserve the integrity of vast tracts of connected and unfragmented open space and wildlife habitat. This study reviews the effect of five alternative permit strategies on the County's ability to preserve unfragmented landscapes through conserving ranch lands.
