Celebrating 35 Years of Conservation

Cake with frosting that says "AG + Open space Happy 35!"

This year, Sonoma County Ag + Open Space proudly celebrates 35 years of preserving and protecting the lands that make our region so unique. Since our founding, we’ve conserved over 12% of the county, protecting vital natural resources, supporting local agriculture, and creating opportunities for everyone to enjoy the outdoors.

From farms and forests to parks and waterways, our work over the past three and a half decades speaks for itself. Here’s a snapshot of what we’ve accomplished together:

While we celebrate these milestones, our mission grows even more critical in the face of climate change. California has set an ambitious goal to conserve 30% of the state by 2030, and Ag + Open Space is leading the charge locally. Our Vital Lands Initiative outlines key conservation priorities to support this goal, focusing on agriculture, greenbelts, parks and preserves, water, and wildlands.

Conservation is about more than protecting land—it’s about building a resilient future for all. Protected forests, grasslands, and pastures can sequester carbon, helping to mitigate climate change. Conservation easements reduce development in areas prone to fire or flooding, enhancing public safety. Preserving open spaces near urban centers provides recreational opportunities, supports local food systems, and reduces greenhouse gas emissions by concentrating development in cities.

Looking ahead, we’re focused on protecting lands that ensure both people and wildlife can adapt to environmental changes. From rising sea levels to warming temperatures, the lands we conserve today will help Sonoma County weather the challenges of tomorrow.

As we reflect on the past 35 years, we’re inspired by what we’ve accomplished together and energized for the work ahead. Thank you for supporting our mission to protect Sonoma County’s natural and working lands—for everyone, now and forever. Here’s to the next 35 years of conservation!
