One of the planet's most recent biomes, a result of the last ice age only 10,000 years ago, the tundra contains unique flora and fauna formed during the last glaciation in areas unrestricted by permanent ice. The tundra region is found in high latitudes, primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as the ...
The flora of the alpine tundra is characterized by plants that grow close to the ground, including perennial grasses, sedges, forbs, cushion plants, mosses, and lichens.

Altitudes above 2,400 meters display characteristics of tundra, with patches of alpine meadows and some trees immediately below the treeline. The ecoregion is in the montane grasslands and shrublands biome, and the Palearctic realm, with a humid continental climate. It covers an area of 90,132 square kilometres (34,800 sq mi).
The Kola Peninsula tundra ecoregion (WWF ID: PA1106) is an ecoregion that covers the northeastern half of the Kola Peninsula, along the coast of the White Sea, a marginal sea of the Arctic Ocean. The maritime effects of the White Sea create a milder climate than would be expected for a region of this latitude.
The Taimyr-Central Siberian tundra ecoregion (WWF ID: PA1111) is an ecoregion that broadly covers the Taymyr Peninsula in the Russian Far North. It ranges from the delta of the Yenisei River in the west, across the Taymyr Peninsula and Khatanga Gulf , to the Lena River delta in the east.
