Invasive Species
A definition of an invasive species is a plant, fungus, or animal species that is not native to a specific location (an introduced species either deliberately or accidentally).
Invasions by non–native species are a major threat to global biodiversity second only to habitat destruction. Invasive species negatively affect terrestrial and aquatic habitats and they cost the Irish economy by damaging our fisheries, blocking navigation, reducing agriculture outputs and wasting resources. Invasive species also have negative impacts on economic interests as well as civil infrastructure.
