The Environment Agency has published an addendum to the 2006 edition of their publication: The Code of Practice is designed to assist developers in the legal management of Japanese Knotweed with cost-effective options management options. It can be used by other parties, such as contractors and consultants as well.
Japanese Knotweed (Fallopia japonica var japonica) is a non-native invasive species of plant that can invade natural habitats and out-compete with native plants as well as being destructive to man-made structures, such as buildings.
Since the publication of the knotweed code of practice in 2006, there have been some changes to legislation which affect pages 6-7 and 36-37 of the code.
The addendum updates on these legislative changes and provides a timely refresh of the code of practice.
