Knotweed in Penarth
Penarth's Victorian seafront and Cardiff Bay interface sit on disturbed reclamation ground, and the old Penarth dock and railway siding beds remain a recurring source of knotweed along the foreshore.
Penarth sits within our South Wales coverage, where the main local pressure is ex-colliery land, valley railway routes and shared terraced boundaries.
