Album of La Center Field Trip

Selected photos by Rod Crawford and Laurel Ramseyer from our 3 October 2017 spider collecting trip to sites near La Center, Clark County, Washington. First we visited a county "legacy lands" tract on the bank of the East Fork Lewis River, where we quickly added 16 species to a prior sample of 12. Our main business was across the freeway at Allen Canyon Natural Area, property of the Columbia Land Trust, where canyon forest, riparian marsh and a forest-bordered upland field gave us 36 species in a short day, including some very cool stuff! Laurel got only 2 specimens in conifer cones, but can't complain — one of them was Washington's first specimen of tiny Comaroma! Her account of the day is here.
