Research Questions: What are the impacts of knotweed on our ecosystems? How do knotweed populations compare across our region? Are knotweed populations changing over time and in relation to climate change? How can we manage knotweed populations?

Why this matters

Invasive knotweed is disrupting ecosystems across the Gulf of Maine watershed. We need more data to understand how knotweed populations are changing so that we can find ways to control it.
