Since 1990, we’ve worked to increase appreciation and stewardship of Sonoma Valley’s natural heritage and create measurable benefits in areas of land, water, climate change and biodiversity. 

Celebrating with Sonoma Ecology Center Victory Gardens 


To launch our 30th anniversary year,  we gifted 300 Victory Garden Starter Packs to the community. Hundreds of people came out to celebrate with us. If you did not get one on Saturday, you can sign up to be the first to know about our next event.     









Origin Story 

This year marks Sonoma Ecology Center’s 30th anniversary. Sonoma Ecology Center was founded in 1990 after the first global Earth Day celebration, held locally on the Sonoma Plaza. 

Sonoma Valley’s first Earth Day drew thousands of people together around the idea that Sonoma Valley is a special place we live in and love, and it is worthy of our care. Parades, green technology demonstrations, music, films, food, dancing, speeches marked this momentous celebration. 

After Earth Day in 1990, we knew that something important had happened. Building on this momentum, Sonoma Ecology Center was founded to continue the education and bridge-building functions Earth Day had launched, and continue to help our community take care of this place we all love.
