Accredited Tree Work Contractors

Accredited tree work ContractorsTrees exist in a wide variety of situations. If they are to provide the highest level of benefit to present and future generations it is important that tree care is undertaken in a professional manner. 

Tree work (arboriculture) requires a high degree of technical competence, supported by training and experience. For these reasons DEFA recommends that tree work is undertaken by well trained, competent arborists, experienced at the type of work being undertaken, e.g. tree pruning/tree removal.

The table below shows a list of businesses operating on the Isle of Man who employ arborists that have demonstrated they have a defined level of arboricultural knowledge:
