New Québec Central Plateau
This ecoregion in north-central Québec is comprised of the Kaniapiskau Plateau and a large
part of Lake Plateau to the south and east. It is marked by cool summers and very cold winters.
The mean annual temperature is approximately -4.5°C. The mean summer temperature is
8.5°C and the mean winter temperature is -18°C. The mean annual precipitation ranges
from 600 mm in the north to 900 mm in the south.
It is characterized by open (less than 50% cover) stands of black spruce, dwarf birch,
northern Labrador tea, and lichens. The shrub component usually comprises about 50% of the
ground cover. Vegetative cover is reduced on colder, dry sites; poorly drained sites support
Labrador tea, sedge, and sphagnum moss. Portions of the plateau reach elevations of 915 m asl.
Its eastern border forms an escarpment overlooking Labrador Hills, but elsewhere its surface
merges with Lake Plateau, sloping north and west from over 750 m asl to 350 m asl. Sporadic
discontinuous permafrost with low ice content is prevalent throughout the northern and
southeastern parts of the ecoregion. Only isolated patches are present in the southwest.
Bare rock outcroppings are commonin the ecoregion. Characteristic wildlife includes caribou,
wolverine, snowshoe hare, fox, wolf, coyote, black bear, and waterfowl. Land uses are limited
to wildlife trapping and hunting, recreation, and tourism.
