Larch -- A Fast-Growing Fiber Source for the Lake States and Northeast
Abstract:Preliminary comparisons between Japanese (Larix leptolepis Gord.) and European larch (L. decidua Mill.) plantings indicate that these species, together with their hybrids, will outgrow pine and spruce, particularly on the better Lake States forest soils. Larch has adequate genetic diversity and grows rapidly. It also hybridizes readily, has good wood quality, is resistant to scleroderris canker and spruce budworm, and is adapted to a variety of soils. Recently, the Institute of Paper Chemistry, at Appleton, Wisconsin, established a cooperative larch tree improvement program using seed orchard approach. Pulping studies indicate that 18- to 23-year-old larch and larch hybirds (Larix x eurolepis Henry) can produce higher kraft yields than 50- to 60-year-old jack pine (Pinus banksiana Lamb.) and with pulp strength properties similar to those of jack pine.

- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
