Discussion
To a limited extent, Picea mariana hybridizes with P. rubens, e.g., on disturbed sites in eastern Canada. Natural hybridization with P. glauca, though reported, remains unverified (A.G. Gordon 1976).
Because Picea mariana is a small tree, it has limited commercial value. Frequently it is harvested with P. glauca and used for pulp.
Black spruce (Picea mariana) is the provincial tree of Newfoundland.
