Wrangel Island Reserve
The last place on Earth where woolly mammoths survived — isolated on an Arctic island while the rest of the species had been extinct for 6,000 years — and now one of the most biologically rich High Arctic ecosystems on the planet — the Wrangel Island State Nature Reserve (Chukotka, Arctic Russia; 7,600 km² of island plus 4,700 km² of surrounding sea; UNESCO WHS 2004) sits in the Chukchi Sea, straddling the 180° meridian.
At a glance
Wrangel Island (the most precisely Wrangel single last woolly mammoth 2000 BCE dwarfed isolated insular dwarfism 6000 years after mainland extinction Arctic UNESCO heritage: the woolly mammoth on Wrangel Island is one of the most important recent discoveries in paleontology: the woolly mammoth (Mammuthus primigenius) became extinct on the Eurasian and North American mainland approximately 8,000-10,000 years ago (the end of the last Ice Age; climate change and human hunting are the two proposed causes; most likely a combination); isolated populations survived longer on islands: Saint Paul Island (Alaska) until approximately 3,750 BCE; Wrangel Island until approximately 2000 BCE — the most recent known mammoth population (approximately 4,000 years ago; contemporary with the pyramid-building civilizations of Egypt; the Wrangel mammoths were alive when the Great Pyramid of Giza was being constructed); the Wrangel mammoth population was dwarfed compared to mainland mammoths (insular dwarfism — the phenomenon where large island-isolated mammals evolve smaller size over time because resources are limited; the Wrangel mammoths were approximately 20-30% smaller than mainland mammoths; still larger than an Asian elephant; ivory tusks up to 2.5m long; approximately 500-1,000 individuals at the time of extinction); the cause of extinction on Wrangel (the most likely causes: inbreeding depression (the small population was genetically damaged by repeated inbreeding; genomic analysis of mammoth DNA from Wrangel shows accumulation of harmful mutations); climate change (warming; the tundra-steppe habitat contracted); possible human arrival (the dates overlap with the first known Palaeo-Eskimo settlements on Wrangel)) — the most precisely Wrangel single last woolly mammoth 2000 BCE dwarfed isolated insular dwarfism 6000 years after mainland extinction Arctic UNESCO heritage in any UNESCO world heritage site)).
Key facts
- Polar Bear Maternity Dens: the most precisely Wrangel single polar bear maternity den 400-500 dens per year largest concentration world cubs February spring UNESCO heritage — Wrangel Island is one of the most important polar bear (Ursus maritimus) breeding areas in the Arctic: the island has the highest concentration of polar bear maternity dens in the world (400-500 dens per year — a female polar bear digs a snow den in October-November, gives birth in December-January, and emerges with cubs in March-April); the reason for the concentration (Wrangel Island is an area of late sea ice formation and early sea ice breakup — the bears are forced ashore earlier than elsewhere and the island has good denning terrain (the snow-covered hillsides)); the polar bears (adults up to 650 kg for males; 200-300 kg for females) forage on ringed seals (their primary prey) and walrus; the island is also a significant calving area for the Western Arctic population of bowhead whales (Balaena mysticetus)

History
Human history and territorial dispute (the most precisely Wrangel single Yupik Palaeo-Eskimo historical 1867 Cossack Wrangel 1881 USS Rodgers American claim 1924 Soviet occupation Chukchi territory UNESCO heritage: Wrangel Island has a complex geopolitical history: the island is named after Ferdinand von Wrangel (the Russian naval officer and explorer who searched for it in 1823 CE but did not find it); American exploration: Thomas Long sighted the island in 1867 CE and named it; the USS Rodgers confirmed the island’s geography in 1881 CE; the Canadian-American Stefansson Expedition (1921-1923 CE) attempted to claim the island for Canada and then Britain (Vilhjalmur Stefansson; he landed a small colonization party of 4 Canadians and 1 American; 3 of the 4 Canadians died of scurvy and starvation; the 1 survivor was rescued by a supply ship; Stefansson tried again with a second party which was forcibly removed by a Soviet gunship in 1924 CE); the Soviet Union established permanent occupation in 1926 CE (a border post; regular Chukchi and later Russian administrative presence); the island was used as a polar aviation staging post in the Soviet period — the most precisely Wrangel single Yupik Palaeo-Eskimo historical 1867 Cossack Wrangel 1881 USS Rodgers American claim 1924 Soviet occupation Chukchi territory UNESCO heritage in any UNESCO world heritage site)).

Practical information
- Getting there: Wrangel Island is exclusively accessible by expedition cruise ship (the closest logistics hubs: Nome, Alaska (IAN; connected to Anchorage (ANC) by Alaska Airlines or Bering Air); Anadyr, Russia (DYR; the administrative center of Chukotka; connected to Moscow by Aeroflot (9h)); the season: August-September (the ice retreats in late July; by late September, sea ice conditions are unpredictable and landings become dangerous); typical expedition ships: the Spirit of Enderby, the Silver Cloud Expedition, various Quark Expeditions vessels; cruise duration for Wrangel-only: 12-14 days from Nome or 16-18 days from Anadyr; price range: USD 8,000-20,000 per person for a berth (the remoteness and low visitor numbers makes this one of the most exclusive wildlife experiences in the world; fewer than 1,000 tourists per year visit); Russian visa required for Anadyr departure; the Wrangel landing requires individual permits from the nature reserve (organized by the ship operator))
Getting there
Expedition cruise only. From Nome (IAN) or Anadyr (DYR). August-September season. USD 8,000-20,000/person. Russian visa required from Anadyr. Fewer than 1,000 tourists/year. GPS: 71.2000, 179.9000.
