Wedging Trees with Back Lean
Trees that side scar easily
Larger Trees
Heavy Leaners
Trees leaning the wrong way |
|

The
following are unacceptable practices:
- Domino Felling,
which is cutting notches and back cuts in a series of trees and pushing them over with
another tree
Swing Dutchman
Bypass/Dutchman in the Notch

Wedging Trees with Back Lean |
|
|
- Determine the height of the tree. This can be estimated quite accurately using one of
these methods:
- Pro-Sight method
- Clinometer method
- Axe handle method
- Determine the diameter (not circumference) of the tree at breast height using a tape.
- Determine the number of segments in the tree by dividing the height (in feet) by the
diameter (in feet).
- Example: a 100 foot tree 24 inches in diameter (2 feet) would yield 50 segments (100 ÷
2).
- Example: a 100 foot tree 12 inches in diameter (1 foot) would yield 100 segments (100 ÷
1).
- Determine the amount of back lean (in feet) by plumbing the tree.
- Use the following table to determine the maximum amount of back lean that can be
corrected with 2 inches of wedging.
