Japanese knotweed can restrict site access and cause structural damage to buildings and hard surfaces. If growing alongside watercourses it can increase the risk of bank erosion and cause flooding hazards. Failure to contain and treat Japanese knotweed could exacerbate and compromise future site operations with increased economic consequences.

Failure to appropriately dispose of waste material containing Japanese knotweed may lead to prosecution under Section 34 of the Environment Protection Act 1990 and Section 14 of the Wildlife and Countryside Act 1981.

Avoid spread by educating workers to check for it on site and in any imported materials such as top soil.

Make sure you can spot it!  Ensure key site workers are able to identify Japanese knotweed and its changing appearance through the seasons. Equally important is the ability to recognise a knotweed rhizome (underground shoots). Display the identification leaflet in prominent positions on site to inform workers.
