Why knotweed spreads in Northamptonshire
The Nene valley and the county's very large logistics-shed development programme mean disturbed ground is constantly being opened up, which is the single most common trigger for knotweed regrowth we see in Northamptonshire.
Main local pressure: Nene valley and constant logistics-park ground disturbance.
