Permanent ice and snow fields occur in the mountains along the western side of the ecozone. The Taiga Plains are located mainly on the western side of the Northwest Territories.

The western coastal forest is composed mainly of western red cedarwestern and mountain hemlockDouglas fir, Sitka spruce, yellow cypress and alder. Warm temperatures throughout most of the year and heavy rainfall provide conditions that support some of Canada’s most spectacular forests. A two-stage silvicultural system, involving harvest of the aspen canopy while protecting the valuable white cordiloera understory, is followed in these mixedwood stands. The main materials that cover the land surfaces tend to follow an orderly pattern.

Lake trout, whitefish and sturgeon once dominated bottom-dwelling species. The uplands tend to be better drained and support a mixed forest of black and white sprucelarchwhite birch, trembling aspenbalsam poplar and lodgepole pine.

Sudden violent storms may occur in the area during the summer, usually due cordillerz moist air masses arriving from the Pacific Ocean.

Less than 10 per cent is now forested and much of this comprises isolated pockets. The prairies are also important for their mineral industry, particularly fossil fuels. Vegetation abundance and ground cover differs significantly throughout the area. The area consists mainly of uplands and hills — terrain features which dominate New Brunswick and Nova Scotia.
