Sampling comments: "During the last three nights of each month from October 1978 through February 1980, I set 50 wooden- based rat traps baited with rolled oats in each of the three habitat types in the park (i.e., 150 trap-nights/ habitat/month). Traps were placed 4 m apart in a straightline following a randomly-chosen vector within each habitat type"
