Site details
Site description: This large 1,243-square-mile (3,180 sq km) uninhabited island lies in Karaginsky Bay along the northwest coast of Kamchatka (58°25'-59°15' N; 163°25'-164°29'E) on a major bird migration route. Ossora village, 34 miles (54 km) to the southeast on the mainland, is the nearest settlement.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs.
Additional biodiversity: The island is an important staging area for 600,000 migrating loons, ducks, cormorants, shorebirds and gulls. The most abundant ducks are common eiders, Steller’s eiders, harlequins, northern pintails, Eurasian wigeons, green-winged teal and scoters. The island also attracts 80 nesting species with the western wetlands inhabited by high populations of common eiders and lesser numbers of harlequin ducks, which nest in the mountains. Following the breeding season, western nearshore waters serve as key molting habitat for eiders, scoters, mergansers and harlequins. East coast sea cliffs support 39 colonies of an estimated 240,000 pairs of nesting seabirds. These include black-legged kittiwakes, common and thick-billed murres, pelagic cormorants, slaty-backed gulls and tufted puffins. Red-necked phalaropes, rufous-necked stints, dunlins and whimbrels are the most numerous of the shorebirds. Russian Red Data Book species regularly recorded include Steller’s sea eagle, gyrfalcon, peregrine falcon, and Aleutian tern. Other notable wildlife: Whales, seals and Steller's sea lions inhabit surrounding marine waters. Domestic reindeer range freely over the island.
Delineation rationale: 2014-08-12 (BL Secretariat): centroid coords adjusted to 58°54'21'N 164°8'57'E and site area changed to (or confirmed as) 255300 ha (rounded), on basis of refined polygon downloaded from Spatial Database on Important Bird Areas of Russia 2014 (© Russian Bird Conservation Union, © Transparent World).
Habitats
Summary of habitats in KBA: The island is about equally divided between coastal plain wetlands on the west and mountains bordered by continuous sea cliffs on the east. There are numerous springs along with rivers and streams that cross the western coastal plain. Intertidal mud flats, marshes and fens, and low bush-hummock tundra are the predominant habitat types with scattered patches of dwarf alder, Siberian dwarf pine and stone birch woods.

Threats
Summary of threats to biodiversity at KBA: While human disturbance and habitat disruption from reindeer herding, fishing and poaching may become increasing problems, severe economic constraints are making it impossible for the regional government to provide adequate response. Funding is essentially unavailable for research and monitoring. High seabird bycatch rates are a big problem in the Japanese high-seas salmon drift-net fisheries in waters east of the island. Between 1993 and 1999, biologists estimate that 483,000 seabirds of 27 species were killed in this destructive fishery.
