This ecoregion comprises the Mealy Mountains and an area south of Lake Melville in
southern Labrador. It is sometimes referred to as the string bog ecoregion. The mean annual
temperature is approximately 1°C, and ranges from 8.5°C in the summer to
-11°C in the winter. The climate can be classified as continental. The mean annual
precipitation ranges 900 mm to 1150 mm.
The growing season runs between 120 and 140 days. String bogs are extensive throughout,
with water covering approximately 25-50% of the ecoregion. Fen vegetation includes sphagnum
mosses, brown mosses, and sedges. String bogs are dominated by dwarf black spruce, tamarack,
Labrador tea, and feathermoss. Spots of black spruce with an understory of lichen, mosses,
dwarf birch, and Labrador tea are found on bedrock slopes near the Mealy Mountains. Black
spruce is the climax species. Alder thickets exist along streams and rivers. Elevation
ranges from 500 m to 670 m asl. The topography is relatively level with some gently surfaces
and a few eskers. Permafrost is scattered, primarily in peatlands. This ecoregion is suitable
for black bear, lynx, red fox, moose, caribou, and waterfowl. There is also some hunting,
trapping, and salmon fishing.
