Upper Santa Cruz River
Riparian Vegetation Map
In 2006, Santa Cruz County’s Community Development Department, the University of Arizona’s Office of Arid Lands Studies, Friends of the Santa Cruz River, and the Sonoran Institute mapped the riparian vegetation along the Upper Santa Cruz River. This effort represents the first map describing the distribution, extent, and species composition of the riparian vegetation from the U.S./Mexico border to the Santa Cruz/Pima County border.
The mapping effort focused on 7 vegetation formations. A formation is a vegetation type that is defined by the structural appearance of the dominant species present, such as forest or shrubland. The drawings below summarize the formations mapped, in addition to the major species that were found.
This vegetation map creates a baseline or ‘snapshot’ in time of the location and composition of riparian vegetation along the Santa Cruz River.
Local residents and managers will have a better understanding of the location of important riparian vegetation. The Map Booklet provides a vegetation ‘road map’ for easy viewing of the mapping results.
