Why knotweed spreads in Greater Manchester
The Irwell, Medlock and Mersey, together with the region's mill and rail legacy, keep knotweed widespread across Greater Manchester. Apartment-led regeneration in Salford and central Manchester means much of our work here is commercial excavation under tight programme deadlines.
Main local pressure: River valleys, mill land and city-centre regeneration sites.
