Develop the skills to identify winter trees using clues found in buds, fruits, leaf scars, bark, and branching patterns. Leaves are one of the first characteristics taught when identifying trees. By learning to use other parts of the tree for identification, participants can develop the skill to identify trees even in winter when leaves are gone.
The class begins with a self-paced online lesson, where you will learn the foundational skills and terminology related to identifying deciduous trees. Then come to The Morton Arboretum for the field session, when you will develop and hone your tree ID skills with the guidance of the instructor. As you walk the grounds of the Arboretum, you will work with other participants to practice identifying trees using the skills you learned online.
This program includes self-paced online components and an in-person session.
