Album of Gazzam Lake BioBlitz Field Trip

Selected photos by Rod Crawford from my participation in the Bainbridge Island BioBlitz, 30 May 2015. I sampled and recorded spiders and other invertebrates at Gazzam Lake Nature Preserve, southwest part of Bainbridge Island, Kitsap County, Washington with some help from Avery Bowron and Molly Esteve. In 8 hours I got 36 spider species (supplementiing a 37-species sample from the NE part of the island in 1986). I recorded additional species that were either non-spider or not identifiable to species, totaling over 70 species of everything for the day. Best catch was a male Hypomma marxii from Spiraea foliage; second time in my life I've taken that rarity. Gazzam, Gazzam!
