Invasive species, ecosystem services and valuation. Invasive alien species (IAS), defined as those non-native species that threaten ecosystems, habitats or species, are key drivers of human-caused global environmental wowinternetdirectory.com heralded as the second greatest agent of species endangerment and extinction after habitat destruction, particularly on islands, IAS are also inflicting serious.
