Join Instructor Steve Chisholm, Jr. Arborist, Aspen Tree Experts for a one-day introduction to the art and science of identification of woody landscape plants with New Jersey Certified Tree Expert Steve Chisholm as our instructor. Steve will show us how to use a dichotomous key to identify plants and will explain the terminology used in keys to describe plant characteristics. He will also discuss the physical characteristics used to group plants into families. We will focus on 40 to 50 individual trees and see examples of each in the Arboretum. Handouts and useful web sites will be provided. We recommend you purchase, before the class, the Sibley Guide to Trees by David Allen Sibley, which is available in the Arboretum gift shop, as an introduction and guide for the class. This course carries 5.5 CEUs for ISA arborists and 6 CEUs for PA landscape architects.
