This Tundra Region
This tundra region spans an area of 26 million hectares. Around 24.2% of the land is
covered by slow growing forest. The remaining area is dominated by bogs, fens, and
thousands of small lakes and ponds. Two thirds of the area in this region is covered
by muskeg, a type of acidic soil.
There are a variety of organisms that inhabit this region. The most common tree
species, all deciduous, are the white birch, dwarf birch, and willow. Animal species
include, but are not limited to, the woodland caribou, polar bear, arctic fox, arctic
hare, Canadian geese, snow geese, willow ptarmigan, and several species of duck.
This region spans an area of 50 million hectares, amounting to two thirds of Ontario s
forests.
