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.

Upcoming Events

Licensed Tree Experts (LTEs) & Licensed Tree Care Operators (LTCOs)

The Tree Experts and Tree Care Operators Licensing Act was passed on January 16, 2010 to address the serious injuries and fatalities in the arboricultural industry, an increase in unresolved local consumer affairs complaints against tree care companies arising from dishonest, “fly-by-night” tree care operations, and the continuation of poor arboricultural practices that put tree owners and their properties at risk.   For more information click here!

Watch the "Tree Experts and Tree Care Operators Licensing Act - How Will It Affect You" session from the 2017 Garden State Tree Conference with Gary Lovallo, from Chestnut Arboricultural and Forestry Services, and Joseph Greipp from Meadow Lakes Arboretum.
