Dont let invasive species undermine your landscape plans
elcome to our invasive species resources page
Below is a selection of useful information, guides, identification tools, links and video to help you make informed decisions about invasive plant species problems in Ireland.
hat is an invasive plant?
Invasive plants are non-native species that have been introduced by human intervention, outside their natural range and have a tendency to spread, which is believed to cause damage to the environment, human economy and health. Most non-native species do not cause any harm and only a small proportion are considered to be invasive. [expand title=”read more…”]Invasive plant species are the second greatest threat to biodiversity world-wide after habitat destruction, and they cost the Irish economy by damaging crops, property and control. Estimated costs to the European economy are €12.7 billion each year.
Invasive species of plants can be spread by wind, water, movement of soil, people and animals. Invasive species of animals may be highly mobile in their own right, be deliberately spread by people, or travel by water or soil or through goods in transit. A list of all invasive species legally designated in Ireland can be found in the European Communities (Birds and Habitats) Regulations 2011 which you can read or download from the Government website:
hat if i find an invasive species on my land?
If you suspect you have an invasive species on your site either contact us and we will arrange a site visit, or use the resources on this page to make an identification and plan a treatment programme. Please be assured that most of the terrestrial non-native plants can be controlled eventually with a sustained programme of herbicide application. For large scale infestations, or in cases where you are unsure, we recommend using our trained staff. [expand title=”read more…”]
Where spraying is necessary in areas adjacent to, or over, water bodies, consult with the Environment Protection Agency before attempting to undertake any control measures. If you are using a translocating herbicide, please note it will be non-selective and will kill all plants it comes in contact with. It may then take many years for the native flora to re-colonise the area and critical populations of rare plants may never recover
Japanese knotweed is regarded as ‘controlled waste’ under the Environmental Protection Act Regulations and, if not burnt, can only be disposed of in registered land-fill sites.
If you have any doubts please call use today.
hat can i do to reduce the impact of invasive plant species?
Avoid using plants known to be invasive, especially in the case of non-native aquatic species
Do not distribute invasive non-native plants that may damage the wider environment to other gardeners
Take steps to prevent the escape of invasive non-native plants into the wild. [expand title=”read more…”]
Destroy or dispose of invasive non-native plants in a responsible way. Do not introduce them into the wild or into areas where they may escape into the wild.
Call an expert if you have any concerns

se these handy invasive species identification sheets
All identification sheets were prepared by The National Biodiversity Centre. The National Biodiversity Data Centre is an Initiative of the Heritage Council and is operated under a service level agreement by Compass Informatics. The data centre is funded by the Department of Arts, Heritage and the Gaeltacht and the Heritage Council.[expand title=”Identification sheets”]
Watch Duncan Stewart on RTE’s Eco Eye explore the impact of several invasive plant species. ‘Eco Eye asks where these strange and unusual species came from and why they are costing us millions each year in extermination. Duncan also visits success stories such as in Lough Corrib where the battle is slowly being won against the invasive but deadly Lagorasiphon Major.’

The importance of the threat of invasive plant species is reflected in a suite of international, European and national policy and legislation. Details on a selection of some of the more pertinent policy and legislation is given, it is not a comprehensive listing.
The Conference of the Parties to the Convention on Biological Diversity (CBD) at their tenth meeting set out a Strategic Plan for Biodiversity with 20 headline targets for 2020 organized under five strategic goals. The mission of the Strategic Plan is to ―take effective and urgent action to halt the loss of biodiversity in order to ensure that by 2020 ecosystems are resilient and continue to provide essential services, thereby securing the planet‘s variety of life, [expand title=”read more…”] and contributing to human well-being, and poverty eradication. Target 9 states:
‘By 2020, invasive alien species and pathways are identified and prioritized, priority species are controlled or eradicated, and measures are in place to manage pathways to prevent their introduction and establishment.’
The European Commission also adopted an ambitious new strategy to halt the loss of biodiversity and ecosystem services in the EU by 2020. The ‘Our life insurance, our natural capital: an EU biodiversity strategy to 2020’ contains six main targets, and 20 actions to help Europe reach its goal. Target 5 covers: Tighter controls on invasive alien species. It is further stated as being:
By 2020, Invasive Alien Species (IAS) and their pathways are identified and prioritized, priority species are controlled or eradicated, and pathways are managed to prevent the introduction and establishment of new IAS.
This target is support by two specific actions:
Action 15: Strengthen the EU Plant and Animal Health Regimes – The Commission will integrate additional biodiversity concerns into the Plant and Animal Health regimes by 2012.
Action 16: Establish a dedicated instrument on Invasive Alien Species – The Commission will fill policy gaps in combating IAS by developing a dedicated legislative instrument by 2012.
On September 29th, 2014, the European Council adopted a Regulation on the prevention and management of the introduction and spread of invasive alien species. The Regulation, that is a binding legal tool for all Member States, entered into force January 1st 2015. The Regulation lays down rules to prevent, minimise and mitigate the adverse impacts of the introduction and spread, both intentional and unintentional, of invasive alien species on biodiversity and the related ecosystem services, as well as other adverse impact on human health or the economy.
There will be a phased introduction of the requirements. Some milestones and key elements are listed below:
List of alien invasive species of Union concern – reviewed every 6 years (proposed list by 01/01/2016)
Member States can request for inclusion of a species based on risk assessment
Functioning structures for Official controls (border controls, goods entry points) by 02/01/2016
Surveillance system by 18 months.
Pathway analysis (18 months**) and pathway action plans.
Early detection issue of alert notification to Commission and other Member States.
Rapid eradication within 3 months after alert notification.
Management measures put in place for widely spread species.
Restoration of damaged ecosystems undertaken.
Reporting and every 4 years* thereafter on – surveillance system, distribution of species, action plans etc.
In 2011, the Republic of Ireland’s Actions for Biodiversity 2011-2016, Ireland’s 2nd National Biodiversity Plan was launched with 7 objectives, 21 targets and multiple actions.
Target 8 states that:
Harmful invasive alien species are controlled and there is reduced risk of spread of new species.
There are 5 supporting actions listed for this under this target:
Prepare, by 2011, detailed species and pathway risk assessments and develop exclusion and contingency plans for priority pathways and high impact species that are likely to invade Ireland.
Continue and enhance measures for eradication, where feasible, control and containment of invasive alien species.
Examine options for rapid response when new invasive alien species are discovered.
Increase awareness within the horticultural and constructed wetlands industries of native alternatives that can be used in place of invasive alien species.
All public bodies will endeavour to use native species, landraces and breeds and the public will be encouraged to do so.
In September 2011, comprehensive regulations which address deficiencies in Irish law implementing the EU Birds and Habitats Directives were signed into law. The European Communities (Birds and Natural Habitats) Regulations 2011 contain important new provisions to address the problem of invasive species. A black list of unwanted species is set out in the Regulations. It will be an offence without a licence, to release or allow to disperse or escape, to breed, propagate, import, transport, sell or advertise such species. [/expand]
