Knotweed in Portishead
Portishead's former dockland and disused power station site along the Bristol Channel shoreline left extensive disturbed brownfield land, which knotweed has colonised alongside the old railway trackbed.
Portishead sits within our Bristol & Avon coverage, where the main local pressure is avon corridor, disused railway land and terraced back-garden spread.
