Invasive species exacerbate the impacts of extreme weather events. Japanese knotweed, also cause erosion as their roots lack well-developed hairs required to stabilize water-logged soil. This erosion leads to sediment buildup downstream and makes the remaining soil less able to retain water, further increasing the risk of flooding.
