Mammals
Back from the coast are brushy thickets where moose calve each spring. In the winter, moose from surrounding uplands return to the refuge to find food and relief from deep snow. Both brown and black bears use the refuge, feeding particularly on early spring vegetation near salt marshes and sedge meadows. Beaver, mink, otter, muskrat, coyote, and wolf can also be found. Trapping is a regular winter activity on the refuge.
Several hundred white beluga whales concentrate in an area extending from the Little Susitna River to the Beluga River, between late May and June. The beluga gather in these nearshore waters to calve, breed, and feed on the large runs of eulachon (“hooligan”) fish that return to spawn in the Susitna River.
