Why knotweed spreads in Bristol & Avon
Bristol carries one of the heaviest knotweed burdens in England, concentrated along the Avon, on disused railway land and in the dense terraced streets of Bedminster, Southville and Easton where rear gardens back directly onto one another. Bamboo encroachment claims are rising alongside it.
Main local pressure: Avon corridor, disused railway land and terraced back-garden spread.
