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 divided by 2)
    • Example: a 100 foot tree 12 inches in diameter (1 foot) would yield 100 segments (100 divided by 1)
  • Determine the amount of back lean (in feet) by plumbing the tree.
