Why knotweed spreads in Lancashire
Lancashire's mill-town river valleys — the Ribble, Calder and Darwen — combine steep ground with dense terraced housing, so infestations here are usually shared between several owners and need coordinated treatment.
Main local pressure: Mill-town river valleys and shared terraced boundaries.
