Each web is numbered from 1 to 5. The traps were collected on Thursday after all animals had been collected. A small handful of rolled oats is placed into each trap, with an additional small amount of oats placed outside the trap door when it is set in the evening. Each animal is then identified to species and weighed to the nearest gram using a pesola scale. Body, tail, foot, and ear measurments are taken to the nearest millimeter using a plastic ruler.
Reproductive status is determined by examining the genitalia.
Marking is done with a Sharpie permanent marker on each animal on the first night's capture for that individual. The animals are then placed back into their traps and released at the exact site of capture after which the traps are rebaited. The animals are then brought back to the laboratory to be processed. Below is the species list of all the small mammals caught on the 6 trapping sites. Each species is given a four letter field code, usually consisting of the firt 2 leters of the genus and the first 2 leters of the specific names.
