We determined temporal and spatial differences in abundance and habitat use by small mammals in southeastern Utah as part of an effort to enhance management of the Mexican Spotted Owl (Strix occidentalis lucida), listed by the federal government as threatened. Woodrats (Neotoma spp.) were captured only in canyons and most frequently in the pinyon-juniper (Pinus edulis–Juniperus osteosperma) vegetation type. White-footed mice (Peromyscus spp.) were found in a variety of vegetation types in both canyons and mesas. The deer mouse (P. maniculatus) was generally the most frequently captured species among vegetation types. We found seasonal and yearly differences in relative abundance of each small mammal species. Our data suggest that the pinyon-juniper vegetation type within canyons is an important component of Mexican Spotted Owl habitat.
