Figure 1. Means and standard errors of mean stem size in all plots grouped by the significant interaction effect between forest type × openness. Means testing results are indicated by lowercase letters. If groups were different then the letters are different.

Figure 2. Means and standard errors of no. of stems in size class 1 in all plots grouped by the significant interaction effect between forest type × openness. Means testing results are indicated by lowercase letters. If groups were different then the letters are different.
