We are a strong voice for the people and wildlife of the Sonoran Desert.
We are committed staff and volunteers and a coalition of nearly 30 member groups, ranging from local to international non-profits, who seek to protect and restore the Sonoran Desert in Southern Arizona.
Through advocacy, education, and collaboration, we protect and restore Sonoran Desert ecosystems and wildlife corridors and defend against threats from short-sighted development.
There are many ways to get involved: speak up, show up, volunteer, donate, and stay informed!
We focus on the Sonoran Desert in Southern Arizona, primarily in eastern Pima County.
The Coalition’s mission is to protect the biodiversity of the Sonoran Desert in Southern Arizona through science-based advocacy, education, and collaboration.
We envision a community in the Sonoran Desert where ecosystems are healthy, valued, and protected, with benefits for current and future generations.
We have lots of great options, including field work and tasks you can do from home.
Support those who are driving local change with a one-time, recurring, or legacy gift.
Spread the word, attend public meetings and events, write letters, and more!
