In 1982,
the New Hampshire Arborists Association took on a new role formerly filled by the State of New Hampshire. The State
Arborists Control Board was the body which tested and licensed arborists but this Board was eliminated by sunset legislation
in 1981. Today the Association tests and certifies new arborists in New Hampshire. [See "Qualifications
and Exam Eligibility Requirements" below.]
Arborist certification establishes a meaningful standard of quality in arboricultural work, improves the
knowledge and skills of practicing arborists, and provides the public with criteria for choosing an arborist. Certified
arborists are professionals educated and trained in:
- Diagnosis and treatment of landscape trees and shrubs
- Proper pruning and management techniques for
valuable landscape trees and shrubs
- Identifying and selecting appropriate landscape trees and shrubs
- Installation,
establishment, and after-care of landscape trees and shrubs
- Understanding the important soil and water relationships which
affect plant growth
- Recognizing tree hazards, construction damage, and mitigation
- Preserving the aesthetic and ecological value
of landscape trees and shrubs
- Understanding and implementing safety requirements for tree care operations including
pruning, trimming, repairing, maintaining, and removing trees and cutting brush.
