Invasive Knotweeds: Evaluating Impacts

How and why do invasive knotweeds cause erosion, and what can you do about it? In this follow-up hybrid course, you will learn about the larger context of knotweeds, including how their management contributes to a more climate-resilient future and ways to integrate new scientific findings into existing conservation practices. The first class will be live virtual and the second will take place in the field. The online portion repeats what the literature tells us for newcomers, and will review the site investigation done in "Invasive Knotweeds: Predicting Impacts," to begin developing management ideas. The field portion will evaluate changes brought about by winter, and evaluate the feasibility of the management ideas developed in the online portion of the course. Attendance at "Invasive Knotweeds: Predicting Impacts" is helpful, though not required.
