Sampling comments: "We trapped small vertebrates at six sites (three ‘‘grazed’’ and three ‘‘less-grazed’’)... We used pitfall and aluminium, box-style or ‘‘Elliott’’ traps (Elliott Scientific, Victoria, Australia) to sample small vertebrates... Two types of pitfall traps were used to trap small vertebrates: 70-cm deep polyvinyl chloride (PVC) drainage pipes with a 15-cm diameter and 40-cm deep PVC buckets with a 29-cm diameter... Traps were alternated along two lines of eight traps, at each of the six sites (16 traps at each site) and spaced 10 m apart. Pitfall trap lines were spaced 30 m apart. Aluminium fly-wire drift-net fencing (30 cm high when installed) was placed over the length of the pitfall trap lines, through the traps’ centre. An additional 10 m of fencing was placed on either side of the first and last pitfall trap on each line... We installed Elliott traps at each site in 9 · 9 grid formations (81 traps at each site) during trapping. Elliott trap grids were located approximately 50 m from pitfall trap lines; individual traps were spaced 20 m apart and baited with boluses of peanut butter and oats... We completed 14, 608 pitfall and Elliott trap nights (n = 3897 winter trap nights or 0.27 % of all trap nights), and 2515 pitfall trap days from April 2009 to May 2011 during 22 trapping events (one event was equivalent to a full trapping session, or 3–4 nights, for one pair of sites)"
