Izembek Refuge is home to both the Southern Alaska Peninsula Caribou Herd on the peninsula from Herendeen Bay to Isanotski Straight and the Unimak Caribou Herd on Unimak Island.

These herds are an important resource for both subsistence and sport users in the region, as well as the large predators and scavengers that live on the refuge.
