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.
