My adopted hometown, Arcata, boasts the first municipal wetland built as part of a sewage treatment system. The marsh, patrolled by numerous herons and hawks, teems with ducks, grebes and shorebirds - and it cleans polluted water so well that the idea has been adopted in communities throughout the U.S. and around the world. I've been leading tours at the marsh since I moved to town in 1994, through
Friends of the Arcata Marsh. I've written several articles about the marsh.
