The Santa Cruz River is a visible green ribbon of life connecting the U.S. (Arizona) and Mexico (Sonora), bridging rural and urban landscapes, joining together diverse stakeholders, and providing important riparian habitat for wildlife. While riparian areas provide numerous benefits to human communities, they are among the most endangered ecosystems. Numerous groups are conducting research, monitoring, restoration, and other collaborative conservation actions along the Santa Cruz River.
