In the experimental plots, some were selectively logged, either to remove bigger trees, to mimic one lucrative logging approach, or to leave a wide range of tree sizes.
( b) Number of trees per ha versus tree sizes.
The landscape distribution of tree sizes was bimodal and skew positive with a maximum tree size of 189.2 cm.
Western larch experienced much higher survival than other tree species across tree sizes.
However locally the distribution of tree sizes was more ragged and variable in shape.
Spruces had the slowest diameter increment across a range of tree sizes.
From there all tree sizes are evaluated separately.
The 30 plots also covered a wide range of tree sizes.
Based upon the 95%% confidence intervals, the nutrient-poor sites had more unequal tree sizes.
Tree mortality caused by MPB varied considerably with percent pine and factors that affect tree size, including tree age, size and growing site.
We let three wild grape shrubs and a hemlock bush grow to tree size.
