Hanna Shoal Walrus Use Area

The Hanna Shoal region is recognized as a critical foraging area for Pacific walruses from summer through fall. The U.S. Fish and Wildlife Service may incorporate protective measures for walruses into authorizations issued for activities within this region.

The Hanna Shoal Walrus Use Area (HSWUA) is defined as the combined 50% foraging and occupancy utilization distributions from June through September as described in Jay et al. (2012).
