A number of non-native invasive plant species are listed on Schedule 9 of the Wildlife and Countryside Act (1981), making it an offence to cause or allow these species to spread into the wild. Common examples include Japanese knotweed (Fallopia japonica), Himalayan balsam (Impatiens glandulifera), giant hogweed (Heracleum mantegazzianum) and several Cotoneaster species. The presence of these plants can have significant legal, ecological and cost implications for development and land management projects.
Whitcher Wildlife Ltd undertakes surveys to identify invasive non-native plant species across a wide range of sites. Our assessments record the presence, extent and distribution of any invasive plants identified, while also clearly setting out any seasonal limitations where species may have died back or are not fully visible at the time of survey.
While we do not carry out invasive plant control works ourselves, we can prepare mitigation and management strategies where appropriate. Depending on the species and site circumstances, we can also advise on suitable specialist contractors to undertake control or eradication works, helping clients manage risks and ensure compliance with relevant legislation.
Whitcher Wildlife Ltd has extensive experience in identifying non-native invasive plant species across all seasons. Our team understands the seasonal limitations associated with certain species, and we provide clear, proportionate advice on survey timing and confidence levels where visibility is reduced. This ensures clients receive accurate assessments and realistic guidance on next steps.
