Gross Characteristics of Lodgepole Pine Trees in North America

摘要

The report presents gross characteristics of North America lodgepole pine (Pinus contorta) as an industrial raw material, based on analysis of complete-tree specimens collected from the full range of var. latifolia in the United States and Canada, and var. murrayana; collected from Oregon and California. The study compares and correlates with latitude, longitude, elevation and tree diameter: general tree characteristics, dimensions, moisture contents, weights, cubic volumes, and stem taper; and specific gravity, weight, volume and moisture content of tree components, including heartwood and sapwood, foliage, and wood and bark of roots, stem, and branches.
