Forests in which red spruce (Picea rubens Sarg.), white spruce (Picea glauca (Moench) Voss), black spruce (Picea mariana (Mill.) B. S. P.) and balsam fir (Abies balsamea (L.) Mill.) either singularly or in mixture, constitute a plurality have played a legendary role in the development of wood product industries in the Northeast. Today, these forest types, occupying 7.9 million acres in Maine alone, serve not only as the mainstay of Maine's pulp and paper industry but also as a source of sawtimber for her expanding sawmill industry. In 1970, the three spruces and balsam fir accounted for 51 percent of the total net volume of growing stock and 40 percent of the total net volume of sawtimber on Maine;s 16.9 million acres of commercial forest land.
