Invasive plant species are becoming an increasingly widespread threat to developments, particularly the proliferation of Japanese Knotweed (Fallopia japonica) across the country. Japanese Knotweed is legally recognised as a very real threat and “knowingly permitting” it to spread across a site and adjacent properties is in contravention of the Wildlife and Countryside Act (1981) and the Environmental Protection Act 1990. It has also been proved to cause considerable structural damage to new development where its spread was not identified in time.

Knight Environmental Limited offers an on-site survey and identification service to enable our Clients to make informed decisions about their sites at the earliest stages. Combined with our hands-on experience of eradicating Knotweed using in-situ and ex-situ remedial techniques, Knight Environmental Limited provides our Clients with cost-effective treatment options to meet their requirements and the re-assurance that the problem will be dealt with.

Knight Environmental Limited has a team of specialists trained in the identification of invasive species and the application of chemical pesticides. The full service we can provide includes design of the treatment strategy, gaining approval of the proposed technique with the Regulatory Authorities, implementation and validation.
