Sampling comments: "daily trap data [were] collected from 12 March 2001 to 30 June 2004... three 153 m and two 121 m aluminum drift fences were placed along forest edges, with 19 L buckets placed every 30 m along each fence. One Y-shaped array was placed in a forest opening to capture grassland-associated species. Two Y- shaped arrays were placed in forested habitat... Captured individuals were either individually or cohort marked" and "released near their site of capture" but recaptures are excluded from entered counts
