Knotweed in Cardiff
Cardiff's docklands legacy along the River Taff and Bute Park's disturbed floodplain, plus old railway sidings near Cardiff Central, have given knotweed extensive opportunities to spread throughout the city.
Cardiff sits within our South Wales coverage, where the main local pressure is ex-colliery land, valley railway routes and shared terraced boundaries.
