F-6 Exhibit 6 Tree Illustrations for Girdling.pdf

Exhibit 6 is a technical illustration document detailing tree treatment methods, specifically girdling techniques for trees across four height ranges (50-55, 60-65, 70-75, and 80-85 feet). The illustrations (2A and 2B) show two different girdling approaches: one at the base of the tree and another at the top, with a consistent 12-inch wide girdle specification. For trees with 10-14 inch diameter at breast height (DBH), the instructions specify removing all live limbs below the girdle for 10 feet. Illustration 2A demonstrates complete removal of live branches below the girdle, while Illustration 2B indicates removal of most live branches below the girdle. The document is part of the solicitation materials for the Middle Fork Wildlife Tree and Down Creation federal contract opportunity, which is a small business set-aside project for forestry support activities.
