Knotweed and the Law

✅ What the Law Says About Japanese Knotweed in Ireland

Japanese Knotweed is a regulated invasive species in Ireland. It is listed under the Third Schedule of the European Communities (Birds and Natural Habitats) Regulations 2011 (S.I. No. 477/2011).

Under Regulation 49(2), it is an offence to "plant, disperse, allow or cause to disperse, spread or otherwise cause to grow" Japanese Knotweed without a licence.

The Wildlife Act 1976 (as amended) also makes it a criminal offence to cause any non-native invasive species to grow in the wild.

While having Japanese Knotweed on your property is not illegal, allowing it to spread onto neighbouring land, public property, or waterways can result in legal action and potential fines.

The movement or disposal of soil contaminated with Japanese Knotweed must also follow Irish waste management regulations. Transporting or dumping contaminated material without a licence can lead to prosecution.

📍 What This Means for Landowners in Cork and Across Ireland

If you find Japanese Knotweed on your property, it's essential to act quickly and responsibly. Under Irish law, landowners can be held liable if the plant spreads beyond their property boundaries.

You could also breach regulations if you move soil or construction spoil containing Knotweed roots (rhizomes) off-site without proper handling and disposal procedures.

For property sales or purchases, surveyors, lenders, and conveyancers typically require:

• A Knotweed Management Plan (KMP)
• Proof of professional treatment or control
• Certification showing compliance with Irish legislation

Failing to provide this documentation can delay transactions or reduce property value.
