Wednesday May 4th, 3:00pm, Commercial Arborist Breakout (Adventureland)

Dr. Frederick Roth will discuss the ways trees respond by changes in their form and structure when they are challenged by natural forces and unusual stresses in their environment. Observing and recognizing these responses can inform arborists’ decisions about tree management and risk assessment.
