@BioDataCentre have produced this short video introducing the threat of invasive alien species to Ireland.

Invasive alien species are animals, plants or pathogens that would not naturally occur in Ireland but are here because of human activity.

When introduced, they thrive to the point of negatively impacting on our wildlife; the services nature provides; our economy, and the way we live.
Invasive species have been introduced intentionally for many reasons, but they may then disperse, escape or be released illegally
They can also arrive here accidently as hitchhikers on our vehicles and belongings or as contaminants on products.
