Course description

Learn to identify and manage the most common invasive plants in the Great Lakes region.  Managing invasive plants is one of the most common restoration tasks. Learn to identify the characteristics of common invasive plants and describe their impacts on the landscape; discuss invasive plant ecology, and learn to which control methods are best suited to each plant.

In this online class, the self-guided material can be completed wherever you have access to a computer, at your own pace.

How Self-paced Online Classes Work:

  • To access the class, you will log into TreeLearning, the Arboretum’s online learning portal. Instructions for accessing TreeLearning will be sent to registrants just after noon on the day the course begins. You have access to the course for 60 days and can complete the materials anytime.
  • Complete the self-paced e-learning modules with reading material, short videos, interactive activities, and quizzes to check your understanding.
  • The course will take approximately 90 minutes. The online materials do not need to be completed in one sitting.
  • There will not be an instructor online with you.
