Album of Hatt Slough Field Trip

Selected photos from a spider collecting field trip to Hatt Slough (a channel of the Stillaguamish River) south of Stanwood, Snohomish County, Washington, on 28 October 2006. One of the most remote spots I've reached by local buses, and a very productive trip. The Washington Department of Wildlife tract here is under stewardship of the Stillaguamish Tribe, who chopped down most of the blackberries, bless them! Rare native Argiope and comon introduced Xysticus were among the meadow spiders. On private land across the slough, tiny, colorful Walckenaeria and other linyphiids were abundant on the foliage of an isolated Douglas-fir grove. Most maps call the place Hat Slough, which is wrong - see this historical article. Photos by Rod Crawford.
