The steps used in a scientific investigation may also vary. Girdling is a slow process compared to felling and is often used only when necessary, such as in the removal of an individual tree from an ecologically protected area without damaging surrounding growth. Girdling is the removal of the bark of a tree in a ring around the trunk. The roots will not be able to get food and die first. ... Firstly the roots die then the upper part I. E.
