Year Book Australia 2003 Environment: Invasive Species

An invasive species is ‘a species occurring as a result of human activities beyond its accepted normal distribution and which threatens valued environmental, agricultural and personal resources by the damage it causes’ (EA 2002a). Invasive species include feral animals, marine pests, weeds, non-native insects and other invertebrates, and diseases and parasites. Invasive species can be native or exotic. They may reduce farm and forestry productivity, threaten native species and contribute to land degradation. Invasive species are acknowledged by the World Conservation Union (IUCN) as the second most significant cause of biodiversity loss in the world, behind habitat loss and fragmentation.
