Decay is possibly the most unappreciated process in nature. Without the break down of living things, critical nutrients become scare in soils. If shed leaves and twigs remained whole, we would soon be buried in debris! As a part of this good and natural process, decay in trees results in the degradation of wood that is the structural framework holding trees upright. For those working with and in trees in the landscape, understanding the decay process and anticipating how decay has spread internally is all in a day’s work.
This session will look at how decay enters and moves through trees, and how trees react to loss of wood due to decay.
