Greater height variability in plantations of white spruce necessitates taking more observations for mean height estimates than are required for red pine. Height/diameter curves can provide reliable estimates of mean or dominant height. A parabolic expression of the height/diameter curve has advantages over a free-hand curve for volume estimates in demanding only objective preparation and requiring fewer height observations, but is less accurate for dominant height estimates.
