The Pennsylvania-Delaware Chapter of the International Society of Arboriculture was founded in 1960. The purpose of this organization is to foster a greater appreciation for shade trees and to promote the science, technology, and practice of professional arboriculture in the states of Pennsylvania and Delaware.

There are currently over eight hundred members in the chapter including commercial, consulting, municipal, and utility arborists, researchers and educators, horticulturists, and individuals interested in the care of trees and landscapes.

Eastern PA
This years Eastern Arbor Day of Service will be held Wed., April 22, at Fair Hill Cemetery at 2900 Germantown Avenue. Start time will be between 7:30 and 8:30 am. Crews and individuals that show up will be provided with t-shirts commemorating the day and lunch will be provided. The cemetery occupies an entire city block and has some fine mature trees that need pruning and a couple dying ones to be removed. We are also planning to plant a tree or two since it would not be Arbor Day without planting trees. If you wish to volunteer please contact Peter Fixler at (610) 574-3849 or write him at
