Why knotweed spreads in West Sussex
The Arun and Adur river systems and the Brighton mainline embankments distribute rhizome across West Sussex, and Crawley's post-war housing stock sits on land where wartime disturbance first established the plant.
Main local pressure: Arun and Adur rivers, mainline embankments and post-war estates.
