Pine Marten

Conboy Lake lies in a transition zone between the wet west side of Washington and the dry east side. As such, it supports numerous mammals known to reside on the refuge—and likely several others waiting to be found or confirmed.

There are 32 mammal species that have been confirmed on the refuge and another 12 that are likely to be present. Mammals that are confirmed present include badgers, beavers, Bendire’s shrews, black bears, black-tailed deer, bobcats, bushy-tailed woodrats, California ground squirrels, big brown bats, Cascade golden-mantled ground squirrels, coyotes, deer mice, Douglas’ squirrels, little brown myotis, long-eared myotis, long-tailed weasels, minks, mountain lions, muskrats, northern flying squirrels, northern pocket gophers, Pacific jumping mice, pine martens, porcupines, raccoons, river otters, Rocky Mountain elk, shrew-moles, snowshoe hares, striped skunks, western gray squirrels and yellow-bellied marmots. Other mammals that are likely to occur on the refuge include California myotis, hoary bats, long-legged myotis, long-tailed voles, montane shrews, silver-haired bats, Townsend's chipmunks, Townsend’s big-eared bats, Trowbridge shrews, vagrant shrews, yellow pine chipmunks and Yuma myotis.

As with birds, the mosaic of fully functioning habitats supports a greater diversity of mammals than would generally be found in a single uniform habitat, or a situation where individual habitat units are too small to provide values that vary from surrounding units. For example, bat species present will roost in the forested areas and forage in the open areas, particularly over the extensive wetland areas. The upland meadows and seasonally dry prairie areas bordered by mixed conifer and pine forest support Rocky Mountain elk through most of the refuge, and mule deer and black-tailed deer are present east of the refuge.
