An arboricultural company is a business that works with individual trees and knows the essentials for their surviving and thriving in different environments. The arborist working for that company has extensive knowledge on an individual tree level and is a micro-manipulator of single trees in a forest or landscape. The arborist practices the science of arboriculture.
There are three common ways you can use to find a tree service employing an arborist(s) that will work in your area.
Use the Yellow Pages:
Look in the Yellow Pages of your telephone book under 'tree services or arborist'. Look for those companies that advertise that they have a 'Certified Arborist' on staff. These arborists have been certified as competent in their understanding of tree biology, insect and disease diagnosis and treatment, and tree pruning by the International Society of Arboriculture.
Use the Internet and the International Society of Arboriculture:
On ISA's "Verify an ISA Certification" web page you will find a series of search options for finding a local arborist.
