Larch Potential in the North-Central States

Projections indicate that there will be an increasing demand for forest products in the next few decades. By far the greatest increase will be in the demand for pulpwood. Among the many species under consideration for meeting the increased demand is larch. Larch appears to have a potential for shorter pulpwood rotations when grown under intensive management (Schreiner, 1970). Several larch species combine good form and rapid juvenile growth with satisfactory wood density and good fiber characteristics. Larch also responds well to weed control, irrigation, and fertilization. Although the yield of pulp per unit weight is lower from larch than from spruce or pine, the yield per unit volume of wood is greater than from spruce or pine and the pulping properties are comparable to those of spruce (USDA Forest Service, 1964; Nevalainen and Hosia, 1969).
