Sampling comments: "Two trapping grids (1.35 ha each)... Each grid was sampled four times (March, May, July and October 2005) during seven consecutive nights each month. Inside each grid 30 pitfall traps and 40 wire-mesh live traps were placed... the traps in each grid were arranged on seven transect lines – four transect lines with live traps interspersed by three transect lines with pitfalls. Each transect, with pitfalls or live traps, had 10 traps spaced out 10 m from each other... The distance between the transect lines was 25 m. Traps were alternately baited with bacon or pumpkin with sardine"
