The Altar Valley Conservation Alliance is a collaborative conservation organization founded in 1995, and incorporated as a 501(c)3 not-for-profit organization. Just southwest of Tucson, Arizona, the Altar Valley comprises approximately 610,000 acres of Sonoran desert grassland, some of the most biologically rich and ecologically threatened biotic communities in the world. Private ranches work side by side with federal, state and local agencies to manage the valley, which is the largest unfragmented watershed in Pima County, outside of the Tohono O’odham Nation to the west. This collection is an archive of reports and other documents specific to Alliance activities.
USDA Agency Priority Goal for Water Pilot Projects Final Report
US Department of Agriculture
Abstract: This report presents the U.S. Department of Agriculture’s (USDA) findings and recommendations for assessing natural resource conditions and evaluating the effectiveness of conservation efforts. Drawing upon the two USDA project studies, St. Joseph River Watershed Project in Indiana and Cienega Creek Watershed Project in Arizona, as well as prior USDA research and assessment activities, the report emphasizes the need for multiple types of assessment approaches specific to the water resource concern and hydroclimatic setting, geographic location, and spatial and temporal scales.
