This mountainous ecoregion is located in the northernmost part of Labrador. It is characterized
by relatively short, cool, and moist summers and long, cold winters. Coastal ice and fog affect
the climate greatly. Mean annual temperature is approximately -6°C, with a mean summer
temperature of 4°C and a mean winter temperature of -16.5°C. Mean annual precipitation
ranges from 400 mm to 700 mm.
The region has a sparse cover of lichen, moss, grass, and arctic sedge. There are patches of
arctic mixed evergreen and deciduous shrubs on sheltered, south-facing valley slopes. There are
white birch/willow thickets which form a transition zone between tundra and spruce forests.
Poorly drained sites and bogs are dominated by arctic black spruce with mixed evergreen and
deciduous shrubs. Rocks in this ecoregion are mainly granite and form steep-sided, rounded
mountains with deeply incised valleys and fjords along the coast. Common glacial features such
as cirques, deep U-shaped valleys, and fjords are widespread. Permafrost is continuous on the
Québec side of the border, and it is extensive but discontinuous on the eastern Atlantic side.
Patterned ground and boulder fields are common. The ecoregion provides suitable conditions for
small mammals, and seasonal habitat for polar bear and caribou. There are no permanent
