Invasive Species in Ireland


The term 'invasive species' is used to label any non-native plant or animal in Ireland that has a negative impact on the environment. They can cause structural complications  to hard surfaces, underground services & buildings (Japanese knotweed or buddleja), pose risks to public health (giant hogweed) and out-compete native plants and animals (e.g. Indian balsam, zebra mussel, grey squirrel).

In recognition of these risks, legislation has been introduced in Ireland  to limit the introduction / spread of the most problematic species. In addition, a new European Union regulation was brought into force in January 2015, which imposes additional legal requirements on landowners to identify and treat invasive species.

Invasive species in Ireland – what can we do?

  • Advising on site management measures to prevent the spread of species during construction works

  • Monitoring the effectiveness of control measures

  • Prepare Invasive Species Management Plans for NPWS approval to secure transport licence
