Tree Thinning


Since many people don't know what tree thinning is, exactly, I thought that an explanation was in order...

The pulp/paper and lumber mills hire contractors to improve there bush lots.  This is done by felling inferior crop
trees and unwanted species to make more room for the most healthy and desirable trees.  Receiving more light and
having more room, the remaining trees grow much faster than they otherwise would have.  Tree thinning and
brushing is typically performed on lots with trees that are 15-25 years old.

Tree thinning is done with a power saw, typically a Stihl 540 or  a Husquavarna.  These saws are sometimes called
brush saws or clearing saws.  They weigh about 22-25 lbs and are attached to a harness.  They have an 11" circular
blade attached to an angle-drive at the end of a long shaft.  In the hands of a professional, these saws are capable
of felling a tree with a 4" stem, in the blink of an eye.

Tree Thinning is usually piece-work, paid by the hector; the more land that you cover, the more that you get paid.
