Japanese knotweed (Reynoutria japonica) is among the most aggressive invasive plants in North America, known for damaging infrastructure, displacing native species, and forming dense monocultures along waterways and other disturbed landscapes. This webinar examines the plant’s origins, its introduction and spread across the United States, and the biological traits that make it such a persistent management challenge. Participants will gain practical guidance on identifying Japanese knotweed in the field and learn about current best practices for effective control and long-term management.
