Non-native Invasive Plant Species Information

Medium Impact / Risk for Ireland

What are Medium Risk / Impact, Alien (non-native) Invasive Plant Species?

In addition to the European Communities (Birds and Natural Habitats) Regulations 2011 - Annex 2 (Part 1) list, Biodiversity Ireland also maintains a list of 'non-native' invasive alien species classifying the impact and risk posed by non-native species in Ireland as 'high risk' and 'medium risk' together with an additional 'watch list'.

Japanese Knotweed Killers have conducted extensive research and collected detailed information to produce guides for all non-native plant species introduced accidentally or deliberately into the wild where they are not normally found. 

 

Non-native species often out compete native species for natural resources causing adverse impacts on the environment.

 

Invasive species can also have significant impacts on conservation and economic interests and may in some cases pose threats, directly or indirectly, to human safety.

 

Reversing the damage of invasive species is a significant land management issue for public authorities as well as for private landowners and can be a costly and labour intensive exercise.

 

Is Having An Invasive Species On My Property Illegal?

Generally having any invasive species listed under annex 2 of the S.I. No. 477/2011 - European Communities (Birds and Natural Habitats) Regulations 2011, on your property does not break the law.

 

Allowing any recognised (currently 35 - see below) invasive species to spread outside your property is another matter.... You could be liable for damages, legal costs and remedial costs if you allow an invasive species onto your neighbour's property or public / local authority area.

Non-native species subject to restrictions under EC Regulations 49 and 50
