The Cedars is a unique ecological area in Sonoma County. Roger is the chief liaison to The Cedars and has been working on this project since first discovering the area in 1981. As we have reached his 35th Anniversary with this beautiful area, we have created a flip-book telling the story of the project, highlighting the people involved and the many beautiful native plants and natural wonders in the area.
