Beautiful. Sustainable. Sonoma.

Tolay Lake Regional ParkWe address challenges related to water supply and quality, open space, rural character, biodiversity, energy, climate change, and quality of life.

The mission of Sonoma Ecology Center is to work with our community to enhance and sustain ecological health in Sonoma Valley.

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.

Our programs are:

  • Research to understand the condition of Sonoma Valley and the Sonoma Creek watershed.
  • Education to support sustainable practices and create future leadership for Sonoma Valley.
  • Restoration to repair damage to waterways, natural habitats, and publicly accessible open spaces.
  • Preservation to protect our natural heritage and public lands.
  • Data & Mapping (GIS) Services using technology to manage and share environmental information for greater efficacy and impact.
What’s important about Sonoma Valley?

Light thru the TreeSonoma Valley is home to amazing variety of species living in a small space. As many as a quarter of California’s species exist in this compact area, a place that comprises only a tenth of 1% of California’s entire land area! Since the Valley is mostly privately owned over thousands of parcels, it needs all of us to be good stewards to sustain this amazing legacy for the future. Our valley is also a watershed–a basic unit around which life on earth is organized. It’s also economically and socially diverse. In short, it offers a lot of what other places offer in a small, human scale valley. It’s a place that may be just the right size to get important things done together. And as we learn more about how to take care of our special place, we may help others do the same in theirs.  Please join us!!


Our values include:

  • Collaboration: We believe that a cooperative, partnership-building, nonpartisan approach is most successful.
  • Information: We believe the community makes better decisions when we provide trustworthy, science-based information.
  • Grassroots: We believe that durable change happens through community leadership and local involvement.
  • Creativity: We believe that for every problem, we can help find common-ground solutions and alternatives.
  • Stewardship: We support agriculture and the 10,000-year tradition of stewardship in Sonoma Valley.
  • Leadership: We identify and create models, techniques, and tools that others can use.
