Terms and practices used in forestry and arboriculture:
A ‘sink cut’ is a triangular cut made near to the base of the trunk in the side of the tree that the tree is intended to fall. It should be made at an angle of approximately 45 degrees.
A ‘felling cut’ is the horizontal cut made into the rear of the tree, just above and towards the sink cut. The felling cut should stop before it meets the sink cut to create a hinge.
The falling action of the tree is controlled because the portion of the tree that has not been cut through creates what is called a ‘hinge’. This allows the felling direction and the rate of the fall to be controlled.
Wedges’ are one of the tools used by forestry workers and the use of them to free a jammed chainsaw is not uncommon.
A ‘bench’ is the term used for the felling one tree into a horizontal position on the ground so that the next tree can be felled to land on top of it. The technique is used to make the task of snedding easier.
‘Snedding’ refers to the removal of branches from the trunk of a felled tree. This is carried out after a tree has been felled and is carried out with a chainsaw.
The ‘danger zone’ is an area to the front and rear of a tree, where the tree is most likely to fall either during or after the sink and felling cuts have been made.
