About this file
This document is an Exhibit containing Tree Treatment Illustrations providing detailed technical specifications for chainsaw tree topping procedures. The illustrations (1A and 1B) demonstrate tree treatment techniques across four height ranges (50-55, 60-65, 70-75, and 80-85 feet), with specific branch retention and removal guidelines. For trees with 10-14" diameter at breast height (DBH), the instructions mandate removing all live limbs below the cut for 10 feet. Additional technical details include a V-type notch requirement of 6 inches deep on the tree top, which must extend across the full length and diameter of the tree top. The document notes that some Administrative Units may have specific variations in cutting depth, which will be specified in the task order.
