Why knotweed spreads in Hampshire
The Test and Itchen valleys, the Solent shoreline and Hampshire's large stock of former dock and military land give the county a persistent knotweed burden. Redevelopment of brownfield plots around Southampton and Portsmouth is the single biggest driver of excavation work we quote for here.
Main local pressure: River corridors, ex-MOD land and dockside brownfield.
