Knotweed in St Austell
St Austell's china clay quarrying industry left vast disturbed spoil heaps and pit edges, known as the Cornish Alps, where knotweed has become deeply established across old mineral tramway routes.
St Austell sits within our Cornwall coverage, where the main local pressure is ex-mining land, mild maritime climate and long disposal runs.
