An arborist is responsible for trimming, hedging, and removing trees within their area of supervision. These duties are performed through the use of hand-powered tools, electric-powered tools, and (often) with their bare hands. Arborists should ideally have a natural "green thumb" and strive to keep trees active, healthy, and thriving. They also plant trees and perform general landscaping duties. They take part in designing park and other venue layouts with planted trees.
Employers generally require that an arborist hold a bachelor's degree in arboriculture, horticulture, forestry, urban forestry, environmental conservation, botany, soil science, or a related field from an accredited university. Certain states may also require licensing, meaning employees must retain necessary licenses and certification status.
Experience is generally required to become an arborist, usually at least three years. If an individual has fewer than three years of experience in the field or a closely related field, they are usually required to first take on an apprenticeship before you can become a fully certified arborist. Once they are certified, they must recertify every 3 years to keep their arborist license active. Two optional additional certifications offered for arborists include master certified arborist and certified tree worker.
