The landscape of our community has changed. Now is the time to harness our strength and spirit, together. We will be with you every step of the way, to rebuild a community that is more resilient, healthy and thriving.


How is our Valley doing? We monitor, analyze, map, and report on broad measures of ecological health in Sonoma Valley.


We provide educational and outdoor programs for thousands of students in Sonoma Valley.


We foster and maintain publicly accessible open spaces, including Sugarloaf Ridge State Park, Van Hoosear Wildflower Preserve and the Sonoma Overlook Trail.


Since 1993, we’ve worked side by side with landowners and volunteers on projects that restore, protect, and improve our natural heritage.


Sonoma Ecology Center is committed to working with the community to achieve and sustain ecological health in Sonoma Valley. Anyone looking for useful information on ways to help is invited to click on the links below.
