A polesaw (also pole saw or giraffe saw) is a saw attached to a pole or long handle that is used for pruning tree branches that are beyond arm's reach. [1] [2] A polesaw allows its user to cut high branches without the use of a ladder. [3] Polesaws can be manual or motorized.
Chainsaw limbing. When the tree is lying on the ground, branches may be storing enormous potential energy through mechanical strain. When a branch is cut, often with a chain saw, this energy can be released suddenly and the branch can jump dangerously. In addition, a branch may be supporting the tree, and the tree can fall or roll when the ...

The remaining part of the tree's diameter is for the back cut, which weakens the tree structurally enough for it to fall without splintering and other unwanted effects. There are three types of directional felling notches that are most commonly used in the logging and arboriculture industries by chainsaw operators.
Depending on the use of the cut material, the length of time between cutting will vary from one year for tree hay or withies, to five years or more for larger timber. Sometimes, only some of the regrown stems may be cut in a season – this is thought to reduce the chances of death of the tree when recutting long-neglected pollards.
Cutting trees with the highest value and leaving those with lower value, often diseased or malformed trees, is referred to as high grading. It is sometimes called selective logging, and confused with selection cutting, the practice of managing stands by harvesting a proportion of trees. [9] Logging usually refers to above-ground forestry logging.
