Sampling comments: "all sampling" occurred "between late June and mid-August. Non-harvested plots and 810 year post-harvest plots were sampled in 2003, 1315 and 2325 year post-harvest plots in 2004, and 23 year post-harvest plots in 2005"; there were "three replicate sites" in three plots and four in two (the non-harvested and 8-10 year sites) and sampling was with "Nordlander pitfall traps... Four 80 m long transects were randomly positioned within each site... Pitfall traps were positioned every 20 m" (i.e., 17 sites x 4 transects x 5 traps = 340 traps) and were sampled on two occasions for two weeks at a time
