Biological invasions are a major threat to biodiversity, second only to habitat change, and have been a primary cause of species extinction over the last 500 years. For example, invasive alien species are cited as a factor in over 50% of animal extinctions where the cause is known, and for 1 out of every 5 (20%) of extinctions, invasions were the only cited cause. Invasive alien species (IAS) are also among the most important threats to globally threatened species. Invasives are the second most important threat to birds, impacting 52% of Critically Endangered species and 51% of all threatened species. They are the fourth most important threat to threatened amphibians (possibly even underestimated owing to uncertainty over the origin of chytridiomycosis), and third most important for threatened mammals. Furthermore, invasions cause huge economic losses – e.g. costs in Europe exceed 12 billion euros per year – they are responsible for the spread of many diseases, and can disrupt ecosystem services of crucial importance for human well-being, such as food security and access to water.
