 ), and in the river valleys blackpoll warblers (Dendroica striata).The cliffs of the Seward Peninsula and St. Lawrence Island in particular are nesting sites for a variety of seabirds including common murre and thick-billed murre (Uria aalge and Uria lomvia) and tufted puffin (Fratercula cirrhata)

The ecoregion also includes the Walrus Islands in Togiak Bay which as the name would suggest are home to Alaska's largest concentration of walrus in summer.There are small human communities in the region, some mining on the Seward Peninsula and some possible over-hunting of caribou, but these are large blocks of largely unspoilt habitat.
