Volunteers with Friends of Fort Worden, equipped with long-handled weed wrenches, dig up and throw away clumps of Yellow Lupin from below the pier at Fort Worden State Park during a work party on Saturday. The Yellow Lupin, although pretty to look at when in bloom, is an invasive species that crowds out native plants, such as Yellow Sand Verbena. (Steve Mullensky/for Peninsula Daily News)
