*Forest litter consists of tree needles/leaves and other plant debris (including cones) that accumulates on the forest floor.
I began pursuing this question in 2012 by sampling eastern white pine (Pinus strobus) cones and associated litter in Massachusetts. I'll blog about that soon, but since I'm presenting my past spider collecting trips in reverse chronological order, I'm first going to recount a 7-day collecting trip that Rod Crawford and I took in Washington's Chelan and Spokane counties in October, 2013. During The Great Spokane County Expedition, as Rod playfully dubbed it, I was able to compare the spider catch from fallen ponderosa pine (Pinus ponderosa) cones and associated pine forest litter.
Below are maps showing the locations of our sampling sites. Map 1 shows the relative location of the Chelan Co. (map-center) and Spokane Co. sites (map-right) within Washington state. Map 2 zooms in on the Chelan County sites. Map 3 zooms in on the Spokane County sites. Maps were made with GPSVisualizer.
