About Us

Grassroots Ecology works collaboratively with local governments, public agencies, schools, corporations, individuals, and other nonprofits to care for the lands and waters of Silicon Valley. Our programs engage over 12,000 people of all ages each year to learn about and improve their local environment. By working together across sectors and generations, we multiply our power to sustain and regenerate our local part of the planet.


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.


From its coastal wetlands to its mountains, Silicon Valley has a rich natural legacy. Located within a globally recognized hotspot for biodiversity, it provides habitat for thousands of plant and animal species—some of which exist nowhere else on the planet. At the same time, Silicon Valley is home to over three million people and some of the largest tech companies in the world.

While the close intersection of urban and wild makes our region a wonderful place to live, it also creates some challenges: increased flood and fire risk, degraded and fragmented habitat, contaminants in our soil and waterways, and the proliferation of invasive species at the expense of biodiversity. These issues—all exacerbated by global climate change—chip away at our environmental health and community health.

To address this need, our team engages 12,000 people annually in environmental restoration, community science, and educational programs at outdoor spaces throughout Silicon Valley, from the foothills to the bay. Together we are creating vibrant, healthy lands and communities that are resilient in a rapidly changing world.
