The ecoregion is a transition zone between the taiga forests to the south, and the treeless arctic tundra to the north. 50% of the territory is herbaceous cover, 18% moss and lichen, 6% shrubs, and about 1% tree cover in protected areas and along river courses. [3]

The ecoregion to the north is the 'High Arctic tundra' (colder and wetter), to the south is the Low Arctic tundra (warmer and wetter). [2] The bedrock under the western extent is Paleozoic and Mesozoic sedimentary rock with a relatively flat cover of glacial moraines and marine deposits.
A further 6% of the land, supports herbaceous cover. [5] In the north, only the hardiest cold-tolerant vascular plants can survive, such as sedge ( Carex ) and cotton grass ( Eriophorum ). In a few low-lying, protected areas there can be small stands of Arctic willow ( Salix arctica ), Dryas species, and low-growing purple saxifrage ( Saxifraga ...
