#2 – Assess the side lean – This often determines whether or not the hinge will hold and whether or not you may need to remove some weight from the “bad” side. This also provides the information necessary to determine the “good” and “bad” sides of the tree for the feller to stand when making the final cut.

Is selective cutting expensive?
(Cons) Disadvantages of selective-cutting: • Expensive and time-consuming • Some species will not regenerate (regrow) as fast • More exposure to weather damage such as ice, storms, and fires • Lots of stumps and other tree debris left behind • Removes genetically superior trees, whose seed is needed to keep forest …
What are the benefits of clearcutting?
Clearcutting pros: It creates wide, open spaces with lots of sun exposure. This allows the most sunlight to reach tree seedlings that require full-sun conditions to thrive. Clearcutting also creates forest clearings that are habitat for some species of songbirds, deer and elk.

What are the benefits of topping a tree?
Tree topping enhances the general structure and appearance of the tree, shielding it from creating broad or frail branches. Topping prevents branches from crossing each other, growing with weak crotches and eventually competing for space in the crown.
