Sonoma Ecology Center was founded in 1990 after that year’s Earth Day celebration on the Sonoma Plaza. Sonoma Valley’s 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, and speeches marked this momentous celebration.

After Earth Day in 1990, we knew that something important had happened. We also saw that the real work still lay before us. Building on this momentum, Sonoma Ecology Center was founded to continue the celebration and bridge-building that Earth Day had launched, and help our community take care of this place we all love.
