Tree topping is the removal or cutting of large branches at the crown of the tree. Topping a tree is usually done in order to prevent damage to the tree or its surroundings. Typically trees must be maintained at a certain distance from power lines and utilities in order to maintain safety. Because imbalance or shallow root systems can often lead to a fallen tree, tree trimming can often be the best way to save a tree from itself. Trimming is a very delicate matter and it does require knowledge of species-specific issues in order to achieve optimal results.
Thinning (Wind Sail Reduction)
Thinning is done to reduce wind sail on large tree – allowing wind to pass through the tree more safely and thus avoiding blowing the tree over.
