The second site is the Pitkin Marsh, which was nearly extirpated by land development in 1960s, but approximately 200 plants remain. A major subdivision is planned in the surrounding area, but a "conservation easement" agreement between the California Department of Fish and Game and the landowner will mitigate in preserving this population. The recent threat to the Pitkin Marsh colony occurred when a parcel, including part of the marsh, was proposed for development as a 29-bed residential care facility. This zoning application is pending with the County of Sonoma.
