Although unfortunate at times it is necessary to remove a tree. It can be a case that the tree is in ill health, causing an obstruction, dangerous or dead tree removal should ideally be the last option.
It is a sign of the times that due to our ever expanding population and the rise in home improvement more and more trees are given way to driveways and home extensions with no plans for re planting.
The picture below shows a lost limb from a storm damaged Beech Tree. Unfortunately tree removal had to take place to make it safe as the form of the tree had been compromised.
