Course Overview

This IAA Arborist Training Course will provide an in-depth study of summer identification of several significant tree species found in Illinois. The primary focus will be on leaf morphology, complexity, and arrangement on both deciduous and conifer trees. This is one of the most important means of identification because of the many characters available for observation and comparison. Identification based on bud, stem, bark, and fruit/seed characteristics will also be covered since they are important features necessary to complete a thorough summer Identification.

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. Approximately 40 different tree species (deciduous and evergreen) will be studied during the course.

The arborist will become proficient in recognizing various plant features that will greatly improve their ID skills, especially during the summer period.

Outcomes
