Component biomass prediction equations are presented for young black spruce (Picea mariana B.S.P. (Mill.)) in northern Maine. A weighted least-squares model was used to construct the equations for small trees from 1 to 15 cm d.b.h., and an ordinary least-squares model for trees less than 2 m in height. A linearized allometric model was also tested but was not used. Equations were developed for over-dry needle, branch, bolewood, bolebark, above-ground, root, and complete tree biomass components.
