Japanese knotw**d growing near a river, stream, or other watercourse on your land is something that should never be ignored. This highly invasive plant spreads quickly in these environments, with fragments easily carried downstream, leading to further areas and potential impact on neighbouring land and local ecosystems. If not properly managed, it can also result in legal issues under the Wildlife and Countryside Act 1981, particularly if it spreads beyond your boundary.
At Southwest Knotw**d, we provide professional Japanese knotw**d identification, treatment and long-term management services across Cornwall, Devon, Somerset and Dorset. We work closely with landowners, homeowners and businesses to ensure Japanese knotw**d is dealt with effectively and in line with current legislation.
If you suspect Japanese knotw**d on your land, especially near a watercourse, early assessment and a structured management plan can make all the difference. Feel free to get in touch with us for honest advice - we’re always happy to help and point you in the right direction.
