Knotweed in Swansea
Swansea's industrial past around the Lower Swansea Valley's former copperworks left extensively disturbed, contaminated land where knotweed has thrived, spreading further along the River Tawe's banks.
Swansea sits within our South Wales coverage, where the main local pressure is ex-colliery land, valley railway routes and shared terraced boundaries.
