Japanese Knotweed
What is Japanese Knotweed
Japanese Knotweed is an invasive plant which is very difficult to control and manage.
It impacts on biodiversity by forming thick, dense colonies that can crowd out other plant species.
It is frequently found alongside:
- roads
- railways
- watercourses
Information on how to identify, stop the spread and dispose of Japanese Knotweed is available on the Government website.
