Sampling comments: sampling was during "26 August - 2 September 1980" and trap night total is apparently exactly 1/3 of the overall three-sampling period total stated in the text; "Each trapline was a straight transect of 20 trap stations spaced at 15.2-m intervals. We set two 'Museum Special' snap traps and one metal cone pitfall trap within a 1-m radius of each trap station centerpoint for three consecutive nights... Snap traps were baited with a mixture of peanut butter, rolled oats, and ground walnuts or sunflower seeds"; number of traplines is unclear
