Knotweed in Winchester
Around Winchester the River Itchen's water meadows and the old Didcot, Newbury and Southampton railway cuttings have allowed knotweed to establish, spreading further via disturbed ground near St Cross and the historic water mills along the valley.
Winchester sits within our Hampshire coverage, where the main local pressure is river corridors, ex-mod land and dockside brownfield.
