Methods

We used the North American Census of Small Mammals snap-trapping technique (Calhoun 1948). On each area we established two parallel trap lines 60m apart and 144 m long. Trap stations were spaced about 7 m apart and totalled 20 per line. At each station we set three mouse traps one directly on the line one to the left approximately 1.5m and one to the right. Traps baited daily with homogenized peanut butter were operated for three consecutive nights in late August or early September (360 trap nights per line each year). For the first night of trapping the traps were set between 1400 and 1700 hr and on the following days were tended between 0800 and 1000hr. Specimens caught were recorded by species station number and trap line. Trapping was carried on from 1955 to 1967.? Unit of abundance = IndCountInt, Unit of biomass = NA
