The High Arctic tundra ecoregion (WWF ID:NA1110) covers most of Canada's northern Arctic Archipelago - from the Queen Elizabeth Islands nearest to Greenland in the northeast, and down through the center of Baffin Island. Much of the northern islands are covered in ice, and the climate is very dry with as little as 50 mm/year in places. The ecoregion has very little human habitation, and most of the non-ice terrain is moss and lichen cover. The region supports viable populations of arctic mammals such as muskox, arctic wolves, arctic foxes, arctic hares, polar bears, and caribou.
