In some cases, preservation priorities and recommendations are based on specific vegetation communities. One example is Fremont Cottonwood-Goodding Willow forests within Pima County, Arizona, which are regarded as critical habitat and protected by the Sonoran Desert Conservation Plan. However, a prioritized system based on conditions within Fremont Cottonwood-Goodding Willow patches may afford greater flexibility to land managers, including selective or incremental preservation, which could accommodate funding challenges. This investigation assessed patches in three watercourses within Tucson, Arizona, and addressed the following questions: Are Fremont Cottonwood-Goodding Willow patches exhibiting characteristics related to vigor or decline? Are there significant relationships between patch vigor and channel variables? On-site assessment addressed Fremont Cottonwood-Goodding Willow patch characteristics and channel variables. Significant relationships were found between vigor and proximity of primary flow, channel width, and bank treatment. Vigor results were employed to develop recommendations designed to facilitate preservation decisions.
