Commander Islands

Geographical Information:  The Commander Islands form the western most part of the Aleutian islands’ arc being peaks of a grandiose submarine volcanic ridge which borders the Bering sea from the south. This island arc can be considered as a connecting link between Asia and North America – a bridge along which plants and animals migrated.
Area:  Total area of the Islands is 185,379 hectares. If the Marine Reserve is included there is a total area of 3,648,679 hectares.
Maximum Altitude:  The highest point is 755 metres ASL. If marine Reserve is included the deepest point of the Ocean is -7,030 metres below sea level.
Physical Features: 
The Islands include mountain tundra, motely-grass meadows, wetlands and coastal areas. There are two major Islands Bering and Medney and two smaller islands Arii Kamen and Toporkov plus a number of rocky islets.

The Commander Islands received their name after Commander Vitus Bering, who died there in 1741 after his ship St. Peter wrecked on the otherwise uninhabited Bering Island on his return voyage from Alaska. Bering perished on the island along with much of the crew and his grave is marked by a modest monument. About half of the crew did manage to survive the winter, thanks in part to the abundance of wildlife, notably the newly discovered Steller's Sea Cow, and the efforts of naturalist and physician Georg Wilhelm Steller, who cured many of the men of scurvy by compelling them to eat seaweed. Eventually, a smaller boat was rebuilt from the remains of the St. Peter and the survivors found their way back to Kamchatka, heavily laden with valuable Sea Otter pelts. The discovery of the Sea Otters sparked a great 'fur rush'which drove the Russian expansion into Alaska. Steller's Sea Cow, whose habitat was apparently restricted to the kelp-beds around Bering Island, was exterminated by 1768.

Aleut (Unangan) people were transferred to the Commander Islands early in 1825 by the Russian-American Company from the Aleutians for the seal trade. Most of the Aleuts inhabiting Bering Island came from Atka Island and those who lived on Medney Island came from Attu Island, now both American possessions. A mixed language called Mednyi Aleut, with Aleut roots but Russian verb inflection, developed among the inhabitants. Today the population of the islands is about 2/3 Russian and 1/3 Aleut.

Flora and Vegetation:  Mountain tundra covered by heathers with crowberry, characterised by Arctus alpine, Rhodonendron kamtschaticum, Rhododendron aurea, Loiseleuria procumbens, Motley-grass meadows with Calamagrostis Landsdorffii, Anemone villosissima, Geranium erianthum. Wetlands including lakes, rivers and swamps  sedges (Carex sp) cotton grass (Eriophorum sp), willows (Salix sp), sphagnum (Sphagnum sp) and coastal eco systems  characterized by Senecio pseudoarnica, Leymus mollis, Ammodenia peploides and Mertensia simplicissima.

Birding Highlights:  There are six endemic species and/or subspecies of birds such as the ancient murrelet. Twenty five of the bird species found here are listed in the Russian Red Data Book as threatened or endangered. There have been a total of 203 bird species recorded from the islands and many of these are vagrants. A number of the species recorded are migratory species coming annually to the islands to breed. Ninteen species of seabirds nest annually along the rocky cliffs with an estimated total population of over 1 million birds.

Mammals: The Commander Islands are important for the diversity and abundance of marine mammals. There are an estimated 225,000 Northern Fur Seals (22% of the world's population). Steller Sea Lions and Sea Otters are reasonably common again after almost being hunted to extinction during the 18th Century 'Fur Rush'.

Whale Sighting off the Commander Islands There are 18 species of whales, dolphins and porpoises recorded from the marine area of the Reserve, ten of which or 56% are listed as threatened or endangered. There is a scarcity of land mammals because of the islands extreme isolation. The Arctic Fox found on the island constitute the most ancient and isolated populations of canines in the world.
