New Jersey Arborists Chapter of the International Society of Arbiculture


New Jersey Arborists Chapter of the International Society of Arboriculture



The New Jersey Chapter of the International Society of Arboriculture (NJISA) was founded in 1974. In 2001, the merger of the Arborists Association of NJ (AANJ) and the NJISA created a more unified industry leader in the field of arboriculture, the New Jersey Arborists, Chapter of the ISA (NJAISA). There are currently over six hundred members in the chapter including commercial, consulting, municipal, and utility arborists, researchers and educators, horticulturists, and individuals interested in the proper and professional care of trees and landscapes.

The NJAISA annually hosts the NJ State Tree Climbing Competition, with the overall winner representing NJ at the International Tree Climbing Competition at the ISA Annual Conference. NJAISA also sponsors annual Arbor Day celebrations, a Golf Outing for the benefit of the TREE Fund, Awards Dinner for member and supporter recognition, and an annual Work Day of service. Quarterly membership meetings are held throughout the state to meet our mission of professional advancement to our membership and promotional opportunities to our corporate and business partners.

MEMBER NOTICE: LTE & LTO Law to be fully implemented!

On Monday April 17, 2017, New Jersey Board of Tree Experts' rules were adopted and approved on the New Jersey Register. The Board of Tree Experts can now fully implement the Tree Expert and Tree Care Operator Licensing Act of 2010. This full implementation of the Law and the Rules will directly affect all tree care companies doing business in New Jersey.

The new law repeals the Tree Expert Act of 1940, and creates two new licensing titles: Licensed Tree Expert (LTE) and Licensed Tree Care Operator (LTCO). It requires that at least one person from each company doing tree work in New Jersey be licensed. It also requires companies performing tree care services in New Jersey to register with the Board of Tree Experts.
