Bark-Tissue Thickness of Coastal Western Hemlock in British Columbia

A. E. Bramhall, R. M. Kellogg, R. W. Meyer, W. G. Warren

Abstract


Bark-tissue thicknesses of coastal western hemlock are reported. Variation in these characteristics is considered between sites, trees, and height positions. Total bark thickness did not vary significantly with site, averaging 7.4 mm, 12.2 mm, and 12.6 mm for the top, middle, and butt height positions, respectively. However, the relative contribution of the individual tissues to the total thickness did vary with site. The thickness of all bark characteristics varied with height, being least at the top position, but differing very little between middle and butt positions.
