Invasive non-native plants, including Japanese knotweed
The Environment Agency recognises Japanese knotweed as the UK's most invasive species. Its aggressive growth can damage buildings, foundations and roads, and may result in costly delays for development projects. Legislation has been introduced to support efforts to prevent its spread.
RSK has specialist knowledge of the eradication of non-native invasive plants such as Japanese knotweed and other commonly encountered species.
Japanese knotweed can grow up to 10 cm a day, so selecting the right control and treatment method is essential. Our specialist invasive species team has a variety of site-specific techniques for identifying, recording and dealing with Japanese knotweed.
