Grassroots Ecology leverages the power of volunteers to create healthy lands across Silicon Valley.

We restore native plants to open spaces and neighborhoods, steward creeks and watersheds, and provide hands-on nature education. By increasing biodiversity together, we believe we can restore our own interconnectedness, wellness, and sense of place in a fast-moving world.
