Winter Activities
Training: Winter is the perfect time to prepare for the upcoming season. (Outdoor observations begin as early as mid-March.) Learn to volunteer by taking the self-paced course or attending the scheduled sessions.
Locate plants: Check out new resources on how to find and identify wild parsnip and knotweed plants during the fall and winter!
Project background
Wild parsnip and Japanese knotweed are particularly pesky plants. In Minnesota, both plants are Noxious Weeds on the Prohibited-Control list. Professionals who manage these plants need more information about when they develop leaves, flowers, and fruits. You can help gather that information by volunteering with Pesky Plant Trackers.
