Maritime Barrens

This ecoregion extends westward across the southern half of the uplands of Newfoundland to the Long Range Mountains. Its climate is affected by the Atlantic Ocean, which makes it susceptible to long periods of fog. It is characterized by cool summers and short, somewhat moderate winters along the coast and colder inland. The mean annual temperature is around 5.5°C, with a mean summer temperature of 11.5°C and a mean winter temperature of -1°C. The mean annual precipitation ranges from 1200 mm to over 1600 mm.

Vegetation, Wildlife and Human Activity

Balsam fir is the dominant tree species. Fires have led to the replacement of fir by sparse stands of black spruce, balsam fir, tamarack, and shrubs, along with mosses and lichen. Kalmia and sphagnum moss grow on blanket and flat bogs. The elevation rises from sea level to approximately 250 m asl, and is composed of a mixture of sedimentary rocks and granites. The uplands are rugged and rocky due to erosion, while lower areas have a rolling topography. Conditions are suitable for black bear, red fox, caribou, moose, and lynx. Fishing and recreation are important activities in this region. The major communities include St. John's, Marystown, Channel-Port aux Basques, Grand Bank, Bonavista, and Carbonear.
