This IBA is a central upland area on the Seward Peninsula, from Port Clarence and Grantley Harbor on the southern edge to the boundary of the Bering Land Bridge National Preserve on the northern edge, and between the Kougaruk River on the eastern edge and the Winter Trail on the western edge.

Ornithological Summary

This area of mostly montane tundra encompasses one of the two core breeding areas for the Bristle-thighed Curlew. It supports about 40% (1,880 pairs) of the breeding population (Handel et al., unpubl.). It is also a major breeding area for a suit of large montane nesting shorebirds. Based on percentage of the population of Bristle-thighed Curlews nesting on the area the central Seward Peninsula qualifies as an IBA of global importance.
