This unique ecoregion is characterized by its sparsely populated vegetation and wildlife, yet it holds great significance as a vital haven for migratory birds and coastal sea mammals.

The lichen tundra and bare ground is more common in the north, and in the lichen-moss communities the grass-shrub layer is thin.

[4] Marshes are heavily influenced by the strong spring floods, and the rains in the early autumn.

Mammals in the area are limited to Arctic fox, lemmings, and a few small herd of reindeer.

There are estimated to be 50 species of nesting birds, and the area is an important extension of the Atlantic flyway.
