What is an Arborist?         IN00531A.gif (1591 bytes)

An arborist is someone who, through education and training is qualified to practice arboriculture. Arboriculture is the application of standards and techniques developed to improve the condition of shade, ornamental and fruit trees. Practices include pruning, cabling, bracing, fertilization, aeration and the control of insects and diseases. The arborist is knowledgeable about the typical growth habits and preferred site location and conditions of healthy trees and is able to diagnose problems from the obvious insect infestation to the less obvious environmental stresses such as changes in soil grade or drought that may affect tree health.

An arborist license, issued by the Department of Environmental Protection, is required to practice arboriculture for hire in The State of Connecticut.
