Are you interested in growing healthy trees? Then, Join Les Werner, Ph.D., in a hands-on, macroscopic examination of trees: how they grow, their tissue types, response to wounds, and reactions to external loading forces.  
In this application based workshop participants will gain an understanding of tree growth patterns, their vascular system, how branches attach to trees, and how trees respond to wounds at both the wound and whole-tree level through lab and field based exercises including tree dissection. Specifically, the workshop will cover:
  • What is a tree?
  • Primary growth and elongation
  • Secondary growth 
  • Branching
  • Wounding and Wound Response/CODIT
  • Reaction wood and adaptive growth
This course is prequalified for 7.25 certified arborist CEUs and 7.25 BCMA – Science CEUs from ISA.
