Overview
Mission
To protect the land, water, and biodiversity of Sonoma County for the benefit of all people, now and forever.
What it reported doing in 2025
Land acquisitions: we work with landowners to assess and understand goals for their properties, which can lead to an acquisition of property or conservation easement, or a transfer of property to the public. Transactions are negotiated to provide the best outcome for the landowner with the ultimate goal of permanently preserving land whether the final ownership is private or public. Land stewardship: we work with the land and community to restore and protect native habitats, creeks, wildlife corridors, productive farms and ranches, and other permanently protected private lands under our care. The program currently stewards 23 conservation properties totaling more than 6,900 acres and actively (continued on schedule o) monitors 47 conservation easement properties totaling more than 8,100 acres. Community programs: we offer a variety of activities, education and outreach aimed at engaging audiences as diverse as the lands and communities we represent. Offerings include on-the-land, virtual and volunteer experiences in addition to education programs, including school field trips and teen educational programs.
