This three-day Tree Biology Workshop combines classroom learning with hands-on field experiences to help participants better understand how trees grow and respond to their environment. Through interactive discussions, live dissections, and real-world case studies, attendees will explore tree anatomy, wood structure, root systems, and the science of Compartmentalization of Decay in Trees (CODIT). Participants will also learn how to evaluate tree structure and compare different nursery stock and planting systems. Whether you are an arborist, urban forester, landscape professional, or passionate tree enthusiast, this workshop will provide practical, science-based knowledge that can be applied to improve tree health, planting success, and long-term tree care.
