3-2- DBH classification
The DBH parameter of surveyed trees was classified into 11 classes
(table 4). The DBH of about 83 percent of the trees was less than 23
centimeters. The smaller diameter, the younger the trees (Millward and
Sabir, 2010). So, the majority of trees are attributed to the young
groups.
