Below is a list of archived invasive species alerts.

A species alert is archived when the need for the species to be tagged as an alert species is no longer warranted. This can be for a variety of reasons including:

  • the species is now well established and beyond the point of possible eradication from Ireland;
  • it is now widespread or;
  • the initial incursions were removed/eradicated and there is no longer an imminent threat of introduction.
