Overview

Wrangel Island is a remote Arctic island administration of Russia. Known in Russian as остров Врангеля, the island sits in the Arctic Ocean between the Chukchi Sea and the East Siberian Sea. It is a small island by global standards but large enough to support a variety of tundra habitats. Wrangel lies close to the 180° meridian, and the International Date Line is intentionally shifted in this area — it is displaced eastwards to keep the island on the same date as the Russian mainland across the 180° meridian.

Geography and climate

The island covers roughly 7,500 square kilometres, a size often compared with the US state of Delaware. Its nearest neighbor is Herald Island, about 60 km to the east, and the closest point on the Siberian mainland lies roughly 140 km away. The landscape is tundra with permafrost, patterned by rivers, lakes and low ridges, and it experiences a severe polar climate with long, cold winters and short, cool summers.

Natural history and wildlife

Wrangel Island supports richly productive coastal and inland habitats for Arctic fauna. It is especially important for arctic species: large breeding colonies of migratory birds, walruses and seals use shorelines, and the island is a key denning area for polar bears. Scientists also highlight Wrangel as one of the last known refuges of the woolly mammoth, where small populations may have survived long after mainland extinctions.

Human history and conservation

Long used seasonally by indigenous peoples and visited by 19th‑century explorers and whalers, Wrangel Island became the subject of formal claims and scientific interest in the 20th century. The island was designated a protected area in 1976 and later received international recognition for its outstanding natural values. Today it is managed as a strict nature reserve with regulated access and research to safeguard wildlife and fragile ecosystems.

Importance, protections and challenges

Wrangel Island combines scientific value, cultural history and conservation priority. Notable features include:

  • High densities of polar bear maternity dens and rich bird colonies.
  • Evidence that makes it one of the final refuges for the woolly mammoth lineage.
  • Legal protection as a nature reserve and recognition that attract international research and conservation attention.

Despite protection, the island faces threats common to Arctic environments: climate change, altered sea ice conditions, and the potential for increased shipping and resource interest as polar routes become more accessible. Conservation efforts prioritize monitoring populations, limiting disruptive activities and maintaining the island’s status as a long‑term refuge for Arctic biodiversity.
