|RELEASING LODGED TREES|
When thinning man-made forests, falling trees are frequently stopped by other trees. The tree is then said to be lodged and this is called a hang-up.
Skilled operators will try to avoid this by felling the tree into open spaces. A proper undercut, an adequate hinge and wedging will help to reduce lodging, but this cannot always be avoided.
BEWARE - dislodging hung-up trees is very dangerous. Think first before deciding how to take the tree down.
Do not walk or work below a hang-up.
Do not try to fell the tree which is holding the lodged tree.
Do not fell another tree on to the hang-up.
Do not climb the lodged tree to loosen its crown.
Recommended techniques for small trees
- Place suitable material (e.g. poles, split wood) on the ground on to which the tree might slide backwards (1a), (2a), (3a).
- Cut the remaining wood which may still connect the tree with the stump, preferably with an axe (1). If a saw is used, it might easily get pinched.
- Use the turning hook to roll the tree to one side (2).
- Use a pole to push the butt end backwards (3).
- Use a manual winch to pull the tree backwards (4). A pulley may help to increase the pull or to place the winch in a safe position, if necessary.
