Why knotweed spreads in East Sussex
Steep chalk-cut valleys behind Brighton and the Hastings cliffs concentrate runoff, moving rhizome downhill into terraced rear gardens. Cliff-top and slope stability constraints often make full excavation impractical on the coast.
Main local pressure: Steep coastal valleys, slope stability and terraced garden spread.
