Occasionally a tree will need to be removed completely. This can be for a number of reasons. In the interests of conservation a diseased tree may have to be removed to ensure neighbouring trees do not also become infected. Other reasons to fell a tree will include safety (to people and property) i.e. if a tree is in a state of decay or in a weakened condition, or if the tree is in an unsuitable area affecting planning applications and construction projects.
Felling a large tree in a restricted area will normally require the tree to be climbed and dismantled in sections. Other times when space, safety and the trees form and allows, a tree may be felled in the traditional forestry sense of the term, by bringing the tree to ground using practiced methods to ensure a safe, controlled and calculated fell.
