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.
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.
