Album of Centralia-Alpha Road Field Trip

Selected photos by Rod Crawford and Laurel Ramseyer from our 7 May 2018 spider collecting trip to sites along Centralia-Alpha Road, 4.5 miles west of Alpha, Lewis County, Washington. We visited a 2006 clearcut with exceptionally diverse spider fauna, then sampled a nearby well-grown western hemlock forest and ended the day at Alpha Cemetery. Largely due to the first site, we recorded an impressive 47 spider species from the area including some very interesting records. Be sure to check out Laurel's account of the day too!
