Course Description

The Winter Tree Identification module will provide an in-depth study of several significant tree species found in Illinois. Identification based on bud, stem, bark and fruit/seed characteristics will be the primary focus for each tree species studied. We will also cover other features important for winter ID, such as tree branching patterns, overall form, even taste and smell. Keen observation skills are necessary for plant ID during the dormant period. Once accomplished attendees will realize that the dormant period provides a more accurate and reliable season to identify tree species. Classes will consist of an indoor study session and an outdoor observation period where specific examples of trees studied in the classroom will be examined. Over 75 different tree species (deciduous and evergreen) will be studied during the course.

Provided Equipment

Pocket knife, 10-15X hand lens, hand pruners, pruning saws and pole pruners.

Outcomes
