Knotweed in Blackwood
Blackwood sits in the Sirhowy valley, where former colliery land and disused mineral railway beds give Japanese knotweed an unbroken run from the tips down to the Ebbw and Rhymney corridors.
Blackwood sits within our South Wales coverage, where the main local pressure is ex-colliery land, valley railway routes and shared terraced boundaries.
