Knotweed in Caerphilly
Caerphilly's disturbed ground around its historic castle moat and former colliery sites nearby has allowed knotweed to establish, with further spread along the Rhymney River valley's old rail lines.
Caerphilly sits within our South Wales coverage, where the main local pressure is ex-colliery land, valley railway routes and shared terraced boundaries.
