- /ɪntrəˈdjust spisiz/ (say intruh'dyoohst speeseez)
a species of plant or animal which is not endemic or indigenous to a particular area but which has been brought, by accident or design, to it.
Compare native species. Also, naturalised species, exotic species.
Australia's array of plants, animals and microorganisms make it one of the most biodiverse countries in the world. Introduced species pose a serious threat to Australia's biodiversity. Introduced plants can become aggressive weeds and displace native plant species, reducing plant diversity and causing land degradation. Just a few examples of major problems are lantana, bitou bush and blackberry. Introduced animals threaten native species by competing for habitat, food and shelter. Foxes and cats have few natural predators in Australia but themselves prey on native birds, reptiles, small mammals and insects. Non-carnivorous introduced animals, such as rabbits, wild pigs, horses, goats and deer, compete with native animals for vegetation, destroying habitats and shelter as they do. Rabbits particularly, with their high reproductive rates, have been especially devastating. Introduced marine species are brought into Australian waters through discharged ballast water from commercial ships, through fouling on hulls and in vessel seawater pipes, or through aquaculture activities. They subsequently threaten the marine environment and commercial activities based on it. The cane toad was introduced into Australia in 1935 and is still spreading.
