Invasive Species Alerts

This section of the website contains information on Invasive Species Alerts issued for Ireland and Northern Ireland.

Issuing an Invasive Species Alert is a key part of the early warning and rapid response to a new invasive species incursion. The purpose of issuing an invasive species alert is:

  • To notify the public and stakeholders of the incursion of a new invasive species.
  • An alert is a part of the triggering mechanism for rapid response to a new invasive species.
  • To inform the public on what action may be required.
  • Encourage the reporting of additional sightings of the species.

Species alerts are also intended to encourage the sharing of information and highlight the need for implementation of biosecurity measures by all relevant stakeholder groups.

For quick reference, we have developed the Alert Tracking Table which summarises the current status of all alerts.

When will we issue an Invasive Species Alert?

A species alert will be issued in the following situation:

  • Upon receipt of the first verified record of a potential invasive species in Northern Ireland or the Republic of Ireland.

Alerts will be updated to notify of additional verified sightings or further spread of the species.

What about species not recorded in Ireland or Northern Ireland?

Invasive Species Ireland and the National Invasive Species Database undertake horizon scanning for potentially invasive species not recorded in Ireland. This ‘Watch List’ will be based on the highest scoring species in the ISI potential invasive species risk assessment. The list will be made publically available upon completion of the risk assessment. The process will remain open to assess new or emerging threats.

From time to time we will need input from experts to help verify a species identification, input into risk assessment and support when deciding the correct response. We have developed the Expert Registry to allow experts to register their expertise in a particular subject. Follow the link below to complete the Expert Registry:
