Small mammal trapping at Mother Goose Lake continued on the Alaska Peninsula National Wildlife Refuge for the eighth consecutive year and the seventh year at the same location. A trapping grid of the one hundred Sherman live traps was used to conduct this study. Four mammal species were captured in 2002: the northern red-backed vole, meadow jumping mouse, masked shrew, and the dusky shrew. Masked shrews were the most abundant specied captured in 2002. Because of previous trends, before the season I predicted the red-backed vole population would collapse this year; their numbers declined from 2001, but they were still relatively sbundant. Meadow jumping mice captures were low this year compared to consistent numbers in the past years. Morphological measurments, sex, and the presence of ectoparasites were noted. Fur dye was used for the second year and we experimented with marking individual animals. Further recommendations for this procedure are included.
