The purpose of this study was to observe the population ecology of small mammals in an abandoned landfill. Eight
species were live trapped in aluminum traps and ear tagged while specific data were recorded. These species included
52 white-footed mice, 230 pine voles, 103 short-tailed shrews, 24 golden mice, 96 Norway rats, 15 harvest mice, 5 eastern
chipmunks, and 1 least shrew. The cumulative home ranges indicate animal separation into micro-habitats in the field.
Population densities, reproductive cycles, and immigrations show possible movement patterns of the animals throughout the
grid. The landfill appears to be recovering as it provides a sufficient habitat for a sizeable population.
