Tree Surgery is not dissimilar from other professions. While there are diligent professionals, there are a small minority of cowboys who put themselves and their employers at risk. They risk injuries and may even damage your property in the process. Finding professionals on the AA or ISA websites is a vital first step for all home-owners.
Qualified aborists, or tree surgeons, hold industry qualifications and liability insurance. Becoming a surgeon in the UK may differ from the US, but the objectives are the same. In the UK, tree surgeons need to hold the NPTC qualification in Chainsaw Operations. They also need liability insurance to cover damage to themselves and surrounding property.
In tree surgery, there are seldom shortcuts. If you just want some cosmetic work done, it might not be so critical to select an experienced tree doctor. However, if your tree has a disease or infestation, a trained professional can salvage your tree and make sure that the issue does not arise to trouble you again.
Remember, trees are living, thriving organisms. Just as humans suffer from disease and illness, so too do trees, a fact highlighted by the spread of Ash Dieback through Europe recently.
An experienced tree-surgeon will be able to identify the tell-tale signs of disease and take the necessary actions. It is also true to note that in a minority of cases, a tree cannot be saved. In this instance the tree will need to be eliminated to reduce the risks of it falling or infecting nearby trees.
