Russian Arctic desert

The Russian Arctic desert is a tundra ecoregion located in the Palearctic biogeographic realm, covering Europe, northern Asia, North Africa, and the northern Middle East, spanning approximately 162,810 km². Classified under the WWF ecoregion code PA11778, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences extremely cold with long winters, short cool summers, and very low precipitation. The dominant vegetation consists of mosses, lichens, sedges, and dwarf shrubs growing on permafrost soils. These conditions create the foundation for the ecological communities found within the Russian Arctic desert.

Ecological Significance

Tundra ecosystems are among the most fragile on Earth, with slow-growing vegetation and species adapted to extreme cold. Migratory caribou, Arctic foxes, and snowy owls are emblematic tundra species. The Russian Arctic desert contributes to the broader biodiversity patterns of the Palearctic realm.

Conservation

Like many tundra ecosystems, the Russian Arctic desert faces threats from permafrost thaw, oil and gas extraction, and rapid Arctic warming. Conservation efforts in this ecoregion focus on habitat preservation, sustainable land management, and protecting corridors that connect fragmented habitat patches.
