Why knotweed spreads in Dorset
The Stour and Frome catchments carry rhizome inland from the conurbation, while Bournemouth and Poole's dense Victorian and interwar plots put mature stands directly on shared boundaries. Coastal and heathland sites often sit inside protected designations that restrict herbicide choice.
Main local pressure: Stour and Frome catchments, protected heathland and dense coastal plots.
