CALIFORNIA — A San Francisco conservation group has reached an agreement to purchase 200 acres in northwest Sonoma County that will expand its existing old-growth redwood reserve. The Save the Redwoods League will buy the property for $4 million from the family of the late Harold Richardson. The land will be added to the group’s Harold Richardson Redwoods Reserve, a 730-acre forest that was acquired from the family in 2018, bringing the combined reserve to nearly 1,000 acres. The reserve… is one of the oldest known coast redwoods south of Mendocino County and the widest south of Humboldt County, according to Save the Redwoods. …The old-growth forest provides habitat for a number of rare wildlife species, including the northern spotted owl and marbled murrelet as well as the California giant salamander, Skilton’s skink lizard and tree-dwelling bats.
