Black Spruce – Picea mariana
Black Spruce–picea mariana
Black Spruce is the most common tree in Ontario and is primarily found in the Boreal forest. Although found on dry and sandy areas, it is often associated with wet or organic sites and can be a slow growing, long lived tree. Black Spruce often occurs in large, relatively pure stands.
It is used primarily for pulp and paper due to its long fibres, but is also used for dimensional lumber and other solid wood products. Spruce in general represents over 40% of Ontario’s harvest over the past decade, and is 30% of the growing stock volume in the province.
