Certain plant species are listed on Schedule 9 Part II of the Wildlife and Countryside Act 1981, and it is illegal to plant or otherwise cause them to grow in the wild. In a development context, species such as Japanese Knotweed, Himalayan Balsam, Rhododendron, Giant Hogweed, Parrot’s Feather or New Zealand Pygmyweed may be encountered. Early detection and treatment is often necessary and desirable to prevent problems later in the process, and ensure compliance with the legislation. Ecology Solutions can advise on the best approach to be taken in any given situation, and is able to call on the services on specialist contractors to treat infestations. While not being legally proscribed, other non-native species are defined as invasive by the Non-native Species Secretariat. Ecology Solutions’ staff are trained in their recognition, and can recommend an appropriate course of action commensurate with best practice. While it is invasive plant species that are most frequently encountered on development sites, non-native animal species listed on Schedule 9 Part I of the Act are occasionally found. Ecology Solutions can advise on the best approach should such circumstances arise.
