The undercut or notch cut is the guiding or aiming slot for the tree and is a V-shaped notch placed on the side of the tree in the direction of intended fall. [4] The back cut or felling cut is made on the opposite side of the tree of the undercut and is cut through the base of the tree severing the “hinge” holding the tree up. [4]
Tree felling: The selected trees are cut down using chainsaws, harvesters, or other mechanized equipment. The felled trees are then prepared for further processing. Timber extraction: Once the trees are felled, loggers extract the timber from the forest by removing branches and cutting the tree trunks into logs of appropriate sizes for transport.
Maintaining proper posture while felling is also important, i.e., kneeling or squatting instead of stooping or bending over with straight legs. [2] [3] The use of improper felling techniques is dangerous, but may also reduce productivity and log supply, leading to increases in production costs in forestry and logging felling applications.

The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products including food and medicine, and contribute to rural livelihoods.
[4] [5] Pollarding tends to make trees live longer by maintaining them in a partially juvenile state and by reducing the weight and windage of the top part of the tree. [6] Older pollards often become hollow, so it can be difficult to determine age accurately. Pollards tend to grow slowly, with denser growth-rings in the years immediately after ...
Perhaps the most important topic the riddle offers is the division between perception of an object and how an object really is. If a tree exists outside of perception, then there is no way for us to know that the tree exists. So then, what do we mean by 'existence'; what is the difference between perception and reality?
