| dc.description.abstract | To maximize utilization of the forest resource, spacing management always plays an important
role in tree planting. It will influence tree height, diameter, mortality, self-pruning, and most
importantly, early growth rate of red pine (Pinus resinosa Ait.) which will affect its logging time.
Although the general nature of the effects of various spacings is fairly well understood, the magnitude
of those effects is not. For example, if the spacing is too wide, reduced self-pruning will result in
more and larger knots. Branch pruning may be required as a result and thus increase the commercial
cost. However, proper spacing providing maximum growing space and directly affect the early
growth rate of red pine, and thus benefit commercial logging. The purpose of this thesis is to use the
data collected by the OMNR and USDA to determine the effects that spacing has on the growth and
stand yield of red pine at varied spacing distances. We conclude that the abundant spacing provides
trees with enough resources to survive and create crown closure. | en_US |
