felling of trees

In order to get timber, mature trees are cut down, or caused to fall to the ground. This process is known as the felling of trees, It can either be done manually or mechanically.

A felled tree is referred to as a log, and the person cutting the trees is called a feller.

In hand felling, an axe, saw or chainsaw is used to fell a tree.

The business of cutting timber in a forest and preparing it for the market is called lumbering.

 The trees should be felled when they have just matured or when they are very near to maturity. These trees have big trunks. The age of good trees for felling varies from 50 to 100 years.
