Grassroots Ecology became an independent organization in 2016 after many years as the Land Stewardship Program of Acterra. Our team engages 12,000 people annually in environmental restoration, community science, and educational programs offered at outdoor spaces throughout Silicon Valley, from the foothills to the bay. 

We are grassroots in name and grassroots in practice. By working across sectors and generations, we multiply our power to sustain and regenerate our local part of the planet. Together we are creating vibrant, healthy lands and communities that are resilient in a rapidly changing world.


Our mission is to engage and educate the public to restore local ecosystems


We envision vibrant, healthy lands and human communities that support and sustain one another and are resilient and adaptable to a changing world.
