Commander Islands

The Commander Islands, also known as the Komandorski Islands, are a remote archipelago in the Russian Far East.

They sit in the Bering Sea, just east of the Kamchatka Peninsula. These islands represent the westernmost portion of the Aleutian Islands chain. While much of the Aleutian chain belongs to the United States, the Commander Islands are part of Russia. They are separated from the American island of Attu by a deep channel. Interestingly, the International Date Line also passes through the waters between these islands.

The islands formed through complex geological processes. They sit on a submarine volcanic ridge that stretches from Alaska to Kamchatka. This ridge began forming at the start of the Paleogene period, roughly 60 to 70 million years ago. The archipelago's relief is quite diverse. It includes folded-block mountains, volcanic plateaus, and terraced plains. These landforms originated from long-extinct volcanoes located at the edge of the Pacific and North American Plates. On Bering Island, the highest point is Steller's Peak. Medny Island features its own high point, known as Stenjeger's Peak.

The climate is maritime and relatively mild for such a high latitude.

However, the islands experience significant precipitation, with 220 to 240 days of rain or snow each year. Summers are often famously foggy and cool. Because there are no true forests, the vegetation is quite specific. The landscape is dominated by lichens, mosses, and marshy plants. You will also find low grass, dwarf trees, and very tall umbellifers. The islands serve as a unique dispersal corridor for certain lichens. A recent study found 36 species of Teloschistales, a type of lichen-forming fungi, in the area. This concentration of species is much higher than in surrounding North Pacific biomes.

The history of the islands is tied to the famous explorer Vitus Bering. In 1741, his ship, the St. Peter, wrecked on Bering Island.

Bering and many of his crew members died during this event. However, a naturalist named Georg Wilhelm Steller helped many survivors stay alive. He encouraged the men to eat seaweed to prevent scurvy. Eventually, the survivors built a small boat from the wreckage and returned to Kamchatka. They carried valuable sea otter pelts with them. This discovery led to a rush of Russian fur traders into the region. Later, in 1825, the Russian-American Company moved Aleut people to the islands for the seal trade.

Today, the islands are sparsely populated and largely protected. Most of the land and marine habitat belongs to the Komandorsky Zapovednik. This is a strictly protected natural reserve.

The only permanent settlement is the village of Nikolskoye on Bering Island. It has an estimated population of 613 people, mostly consisting of Russians and Aleuts.

The local economy depends on fishing, ecotourism, and government services. The village also includes a school and a satellite tracking station. Small groups of houses or tiny villages exist on other islands, such as Medny.

The marine life in the surrounding waters is incredibly abundant.

There are approximately 200,000 northern fur seals and 5,000 Steller sea lions that visit the islands. Sea otters are also common and show a stable or increasing population. The waters provide vital habitat for many whale species, including sperm whales and orcas. Some species, like the North Pacific right whale, are endangered. Bering Island was once the only home for the Steller's sea cow. This massive animal, related to the dugong, was hunted to extinction within 27 years of its discovery in 1741.

On land, the islands support over 180 bird species. Over a million seabirds nest in large colonies along the coastal cliffs. You can find puffins, cormorants, and gulls in these areas. The islands are recognized as an Important Bird Area by BirdLife International. This is because they host many threatened species, such as the red-legged kittiwake. The terrestrial environment is much quieter than the sea. Aside from two subspecies of Arctic fox, most land animals like reindeer and rats were introduced by humans. The islands remain a vital, wild link in the North Pacific ecosystem.
