Abstract:
Growth of different stock types of white spruce and lodgepole pine were compared on untreated sites and sites treated by scalping, where the surface soil and vegetation had been removed by bulldozing; mixing, where the vegetation had been incorporated into the underlying soil; and clipping, where the vegetation was clipped. Height increments varied with measurement period but had a pronounced peak around age 9. The slope of the linear regression of height versus age up to 10 years gave estimates of average annual growth rates which were used to compare stock type and treatment effects. The growth rate of a tree of a particular size at the time of the first measurement after outplanting could not be predicted with confidence. However, the pattern of growth rates in a stock type of a species subjected to a particular site treatment exhibited characteristics that could be used to differentiate species, stock, and site-treatment effects. In white spruce, there was a tendency for growth rate to be related to size at first measurement, though with high variability around the trend. In lodgepole pine, growth rate was independent of tree size at first measurement, and showed less variability.
