Album of 2nd Centralia-Alpha Road Field Trip

Selected photos by Rod Crawford and Laurel Ramseyer from our 24 June 2025 spider collecting trip to Centralia-Alpha Road, east of Centralia, Washington. We'd sampled an eastern section of this road in 2018, but left this western section unvisited, though I'd made a trip plan. Today we visited two different Port Blakely Tree Farm clearcuts (with somewhat different spider faunas) and an older second-growth forest with dense understory, coming home with an acceptable 35 species to fill this hole in collection coverage.
