Selected due to high levels for the criteria 1, 2, 3 and 4, and selected by MARXAN software.

Characteristics A separate window opensReferences

Highly natural shore zones are spread off the coasts of Habomai and Shikotan. The waters less than 50 m deep extend continuously from Habomai and Shikotan to the Nemuro Peninsula. These highly productive waters are home to broad seaweed beds. This high productivity is thought to be a result of the very high concentrations of chlorophyll in the offshore zones in the vicinity of the four islands, plus the contribution of nutritive salt flowing from the Sea of Okhotsk. While sea otters can be seen at Kanakuso Crag, Kabuto Crag, Harukarimoshiri Island, Odake Island and elsewhere in the waters from Shikotan Island to Cape Nossapu, particularly large numbers have been observed at Harukarimoshiri Island (Kitano Umino no Dobutsu Center, 2004.), where breeding has been confirmed as well (Northern four islands (Northern Territories) expert exchanges committee of marine mammal and sea birds, 2000). At Kanakuso Crag and Todo Crag in the Habomai Islands, Steller sea lion have been confirmed to come ashore at non-breeding grounds sites, with the vicinity of Kanakuso Crag in particular being their largest landing site in the four northern islands. Numerous common seal can be seen in the northern part of Shikotan Island. The Habomai Islands also are home to many common seals, which are distributed broadly all the way to Cape Nossapu. Numerous taluses can be observed to have developed in the shore zone of the northern part of Shikotan Island, serving as a nesting ground for spectacled guillemot (Northern four islands (Northern Territories) expert exchanges committee of marine mammal and sea birds, 2000). Numerous spectacled guillemot, rhinoceros auklets and tufted puffins also can be seen centered on the Habomai Islands (Hokkaido Northern Four Islands (Northern Territories) Study Group, 2001). Numerous pinnipeds and sea birds inhabit Nemuro Peninsula as well.

* This is the species list of which meet the criteria. In that matter, this list does not include all species that inhabit the individual area.
Abbreviation in the information is as follows.
[Br/Ne] : Adjacent water of breeding area or nesting site
[Sp] : spawning area
[Ad] : species not used for analysis but add to the list because inhabit information was collected later
[Ex] : species used for analysis but considered to be possibly extinct in the EBSA region (area)
No mark : data of species distribution
