Jenner Headlands is a spectacular 5,630-acre mosaic of redwood and Douglas fir forests, oak woodland, chaparral, and coastal prairie overlooking the Pacific Ocean. The property adjoins Pacific Coast Highway for two and one-half miles adjacent to Sonoma Coast State Park just north of the Russian River Estuary. Many rare and endangered species inhabit the property including the northern spotted owl, peregrine falcon, and red tree vole. Deer, bobcat, coyote, mountain lion and steelhead trout are also found on the property.

This 2009 acquisition was a result of the dedicated four-year effort by the Sonoma Land Trust and the Sonoma County Agricultural Preservation and Open Space District. Five other funding sources: the California Coastal Conservancy, the California Wildlife Conservation Board, the National Oceanic and Atmospheric Administration, the Gordon and Betty Moore Foundation, and Forest Legacy Program. The Wildlands Conservancy loaned and guaranteed loans totaling $10.6 million to insure this acquisition when funding was threatened. It is the single largest conservation land acquisition in Sonoma County history.

In September 2013, Sonoma Land Trust transferred the fee title of the property to The Wildlands Conservancy to manage as a preserve governed by consensus management decisions between TWC and Sonoma Land Trust.

At the time of its purchase, Jenner Headlands was the single largest conservation acquisition in Sonoma County history.


Sonoma Land Trust and The Wildlands Conservancy worked closely in developing a resource management plan to restore the coastal prairie and to aid the recovery of old growth redwood forests from decades of logging. Restoration of logging roads and restoring clear running streams will aid the recovery of the endangered Coho salmon.
