After habitat destruction, invasive alien species are the 2nd greatest threat to biodiversity worldwide.
Notice Nature is teaming up with Invasive Species Ireland to help raise awareness of this issue and to get everyone involved in combating Ireland’s invasive alien species.
What are invasive alien species?
Invasive alien species are non-native species that, as a result of human activity, have been transported further than they could naturally travel and have subsequently disrupted their newly colonised environments.
Alien species can belong to any groups of organisms including birds, mammals, reptiles, amphibians, micro-organisms and invertebrates.
Invasive alien species negatively impact Irish biodiversity through competition, herbivory, predation, habitat alteration, introduction of parasites or pathogens, and dilution of gene pools.
