Abstract:

Forty-four sample hardwood trees felled on 24 plots were separated into three above-ground components--stem, branches, and leaves--and weighed for dry matter content. Tree, stand, and site variables were tested for significant relationships with dry weight of tree parts. Weight increase of stems was a logarithmic function of both stem diameter and height, whereas for branches and leaves, only diameter was significantly related to dry weight. The fact that hardwood stems and branches have much higher weight values than pine is attributed primarily to higher wood densities of hardwoods. Larger crown/ stem diameter ratios observed for hardwoods also help deter relative differences in weight of branchwood. Although not tested rigorously, comparative data on growth rates suggest that loblolly pine produces more usable dry material per unit of land area than upland hardwoods.

  • 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.
