Knotweed is a plant that spreads rapidly and grows in large, dense patches. It can crowd out other species, erode river banks, and cause damage to homes and buildings with its powerful root systems. Despite the widespread damage it has caused, little research has been done on knotweed. More information is needed to help us understand how knotweed is interacting with our local ecosystems and how it might respond to climate change. Collect data in your community to understand the impact knotweed is having in the region.
