Why knotweed spreads in Somerset
Somerset's drainage network and the Levels carry rhizome widely during winter flooding, while the steep valley plots around Bath frequently make plant access the controlling factor in whether excavation is realistic at all.
Main local pressure: The Levels, seasonal flooding and constrained valley access.
