Efforts to restore native grasses, shrubs, and trees to Hammond’s Meadow — known to the Chumash as Shalawa and recognized by the National Register of Historic Places — have been revived by Channel Island Restoration. The nonprofit proposes to further abate weeds with organic citrus and clove-oil spray, restore native vegetation, and maintain the beach trail. A public meeting on May 18 on the county-owned open space included nearly a dozen people of Chumash descent, who suggested that the existing ceremony circle be slightly expanded and moved to a higher vantage point.
