This site is located at the north mouth of Kotzebue Sound and includes Krusenstern Lagoon and a beach ridge-wetland complex that extends southeast to Aukulak lagoon. The site is entirely within the cape Krusenstern National Monument. The 48 km2 Krusenstern Lagoon is protected by a 4 km long barrier bar along its northwestern shore, and lagoon waters average 1.2-2.0 m in depth. A diveristy of tundra and wetland habitats surrounds the area.

Ornithological Summary

Shorebird use of this site received initial attention by Connors and Connors (1985) and more recently through a series of studies that addressed communities of shorebirds nesting over habitats adjacent to the lagoon (Bunn 1988, 1989; Shoroeder 1995). Connors and Connors were present at the site for two seasones (26 May-7 Sep) during 1977 and 1978. Based on 70 ha littoral habitat censused at 5 day intervals they recorded 5,100 total shorebirds or an average density of 2.6 shorebirds/ha throughout the season (r=0.25-0.9). Red-necked Phalaropes, Western, Semipalmated and Pectoral Sandpipers and Long-billed Dowitchers were the most abundant species using littoral habitats at this site.

Also a favorable nesting area of Arctic and Aleutian terns (possibly more than 1% of Aleutian Tern global population).

Until more recent data become available, however, this site is PENDING GLOBAL/CONTINENTAL status.
