Very Large Trees = >40" in diameter                                    Large Trees = Trees 30-39.9" in diameter
Medium/Large Trees = 20-29.9" in diameter                     Small/Medium Trees = 12-19.9" diameter
Small Trees = 5-11.9" in diameter                                          Saplings = Trees less than 5"
