Grays Harbor is experiencing an alien invasion, of non-native common reed. This grass gets 16 feet tall and forms thick stands at the water’s edge. The Grays Harbor National Wildlife Refuge is threatened with loss of crucial habitat for migrating shorebirds. This noxious weed is also beginning to move across the harbor to nearby Ocean Shores. It can be very difficult to remove once it has become established. Please don’t “harbor” this invasive in your yard.
