An arborist is a professional in the practice of modern day arboriculture. A dedicated arborist is a life long learner of their hometowns tree care issues and promotes a standard of professionalism in tree biology and best management practices. An arborist provides ethical sound advice that balances the clients wants and the biologic needs of the tree. Not all pruning and removals are necessary, and an arborist is obligated to educate their clients.
