The National Invasive Species Database provides a centralised source of up-to-date information on the distribution of invasive species in Ireland.

The overall objective of this initiative is to maintain and further develop the national framework for the management and provision of information on invasive species in Ireland. The project will collate Irish data, assess trends, build cross Agency networks and support policy-makers in mitigating the spread and impact of invasive species.


Aims of the National Invasive Species Database initiative:

  • Provide a centralized portal for access to and submission of distribution data
  • Deliver Ireland’s Early Warning System for invasive species
  • Support surveillance and monitoring of invasive species
  • Develop and support Citizen Science recording of invasive species
  • Analyse data for trends in introductions of invasive species to Ireland
  • Work with state bodies, local authorities, NGO’s and interested groups to tackle the threat of invasive species
  • Support development of a European Early Warning and Rapid Response System
  • Connect Ireland’s data to European and international information networks

Significant contributions have been made in recent years in Ireland to addressing the threat posed by invasive alien species, to fill the knowledge gaps and provide information to support policy and management decision making. This includes the development of an invasive species Early Warning System for Ireland.

How does it work?

The National Invasive Species Database project (Ireland) collates distribution data via the National Biodiversity Data Centre for invasive non-native species listed and ranked through a risk assessment process. The species distribution data comes from a variety of sources and goes through a validation process. All validated records (sightings) in the database are made publicly available on interactive maps through the IAS portal.

The distribution data and additional information collated by the Data Centre is compiled in the IAS portal and provided to global and regional information systems. Vitally, this centralized hub of data exchange provides a mechanism for an Early Warning System which has been deployed 13 times since 2007. Additional information is also provided to Local Authorities, researchers, state bodies and awareness, training and recording schemes are ongoing and integral to the data flow process.


For every additional record that is submitted, a clearer picture of the status of that invasive species in Ireland is generated.
