Effect of Initial Stand Density on End-of-Rotation First Log Quality Characteristics of Lodgepole Pine
First log quality characteristics are influenced by crown development due to initial stand density. Analysis was performed to determine the effect of initial stand density on several log quality characteristics for mature lodgepole pine Pinus contorts. A strong negative exponential relationship was determined between initial stand density and the mean of the 5 largest branches per first log. Relationships were determined when first log stem taper, proportion of sapwood to heartwood and wood density at breast height were compared to initial stand density.
