Veteran Tree Care Management

Date: October 18, 2022
Location: Morris Arboretum of the University of Pennsylvania, Philadelphia, PA, UNITED STATES
Organizer: Morris Arboretum
Sponsor: The Morris Arboretum of the University of Pennsylvania
Description: This seminar will examine the special nature of veteran trees. A veteran tree is one that is past maturity and is old in comparison with other trees of the same species. We will discuss current research and some of the preservation practices that are popular in England including retrenchment, propping, and reduction. Like all living things, trees survive through the transfer of energy. This transfer occurs both within the tree itself, as well as between the tree and its environment. Far from being a static process, energy relations are highly dynamic and constantly changing as trees age, decline, and die. Arborist should be aware of these changes, to provide the best advice and management recommendations to his or her clients for the care and preservation of older trees. If weather permits, we will spend a portion of the day outdoors.

Wayne Cahilly, the course instructor, is an International Society of Arboriculture certified arborist, qualified tree risk assessor, and a graduate of the School of Professional Horticulture at the New York Botanical Garden where he has worked for the Science Division, Capitol Projects division, as an arborist, forest manager, arboretum and grounds manager and as the manager of the mapping department. He also owns and operates Cahilly’s Horticultural Services, LLC., a consulting business focusing on pre- and post-failure analysis of trees and aiding the legal and insurance communities.

This course carries 6 CEUs for ISA certified arborists (S=2, P=2, M=2).
