Picea mariana (Black spruce)
Hampton, Nan

Picea mariana (P. Mill.) B.S.P.

Black spruce

Pinaceae (Pine Family)

USDA Symbol: pima

USDA Native Status: Native to U.S.

Black spruce is a very narrow, spire-like tree, growing 30-60 ft. tall with a limited spread. Descending branches, with dark, bluish-green needles, have upturned ends. Lower limbs sweep the ground. Tree with open, irregular, conical crown of short, horizontal or slightly drooping branches; a prostrate shrub at timberline.

Black Spruce is one of the most widely distributed conifers in North America. Uses are similar to those of White Spruce; however, the small size limits lumber production. The lowest branches take root by layering when deep snows bend them to the ground, forming a ring of small trees around a large one. Spruce gum and spruce beer were made from this species and Red Spruce.

Benefit

Use Wildlife: Twigs, leaves and seeds are important wildlife food. Very valuable as nesting sites for birds.
Use Other: Long wood fibres of black spruce are most commonly used for pulpwood, especially for producing high quality papers. A thing of the past now is the gathering of spruce gum, by gummers on snowshoes, carrying long poles fitted with chisels to knock off the resinous exudations. In the old lumber camps, spruce gum was the chewing gum. (Peattie)
