Robert A. Lee Center  220 S Gilbert St, Iowa City, IA 52240 

7:30-5pm April 14, 2025

This workshop provides a solid foundation of tree biology, anatomy, and physiology.  You will learn about how the entire tree grows and functions.  Lecture and discussion will cover foundational arboricultural concepts and practices.  Do you want to learn tree anatomy?  Are you looking for some science CEUs?  Come learn how trees grow and how you can work with them!

$100 for IAA members, $150 for non-members 

Lunch provided | 9 ISA CEUs!
