The most abundant group are plants with 490 species, followed by terrestrial animals with 390 species (of which 90% are invertebrates), and aquatic organisms with 102 species (44 freshwater and 58 marine). Most alien species originate from North America and Southeast Asia and were introduced accidentally. A series of management measures are considered at national level aimed at the prevention, early detection and response, and management of naturalised species.
