Methods
Life forms: ants
Sites: 17
Sampling methods: line transect, pitfall traps
Sample size: 685
Years: 2003 - 2005
Days: 14
Seasons: summer
Nets or traps: 340

Sampling comments: "all sampling" occurred "between late June and mid-August. Non-harvested plots and 8–10 year post-harvest plots were sampled in 2003, 13–15 and 23–25 year post-harvest plots in 2004, and 2–3 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
