11 lodgepole pine study sites were selected in British Columbia, and Alberta for a study of basic wood properties. At each site 20 trees were selected, felled, and sampled at five height levels for relative density, fiber length, longitudinal shrinkage, lignin and extractives content determinations. This report presents wood relative density trends, stem sizes, and juvenile-mature wood distribution in 80 to 100 year-old lodgepole pine stands which grew under various stocking densities (500 - 2300 stems/hectare). In all three diameter classes sampled, a high degree of intra-ring density uniformity was evident, as low density earlywood and high density latewood ranged between 0.30 to 0.60 for western-red-cedar and Douglas-fir 0.25 to 0.80. This density homogeneity contributes to excellent machinability and veneer peeling qualities. When lodgepole pine trees of similar environment were compared at equal age and equal height level there was no relationship between growth rate and relative density. Comparatively low density wood in the large diameter trees was the result of normal physiological influence of the live crown. As crown dominance is reduced, through higher stocking densities, wood density is enhanced in the lower bole but at the expense of log size. And herein lies the paradox because both the solid wood and pulp and paper industry experts believe that industry will maximize profit by planning to grow, harvest, and process larger, rather than smaller, trees.
