A diverse community of abundant, native amphibians is persisting along waterways of urban and urbanizing Tucson. Community and government leaders in Tucson support the concept of urban amphibian conservation in principle. Meanwhile, concurrent, commingled plans for infrastructure improvements and ecological restoration along major urban riparian corridors are being developed under leadership from Pima County, City of Tucson, and U.S. Army Corps of Engineers.
