Japanese Knotweed and other invasive plants
Invasive non-native plants are species that have been brought to the UK and can spread, causing damage to the environment, the economy, our health and the way we live.
They can cause problems for native UK species and reduce the variety of living organisms (biodiversity). They are now widely recognised as the second biggest threat to biodiversity worldwide.
Japanese Knotweed can block footpaths, damage concrete, tarmac, flood defences and the stability of riverbanks. Giant Hogweed can cause harm to human health.
