Knotweed in Penzance
Penzance's Victorian harbourside and former railway terminus sidings have disturbed the coastal ground where knotweed now spreads along the Penlee headland and into nearby subtropical garden estates.
Penzance sits within our Cornwall coverage, where the main local pressure is ex-mining land, mild maritime climate and long disposal runs.
