Pest species are commonly recognised, both nationally and internationally, as a threat to wetlands. In particular, pest animals can have a range of negative impacts on wetlands, including:
Pest animals are exotic animals that have a detrimental impact on the environment, industry or community activities. In Queensland, a pest animal may be a declared animal. Declared animals are pests under the Land Protection (Pest and Stock Route Management) Act 2002 and land managers are responsible for control of them on their land. Some pests are wetland species (for example, water buffalo and the red-eared slider turtle) while others, such as feral pigs, are found particularly in association with wetlands and riparian ecosystems.
Another category of pest animal found in Queensland wetlands is noxious fish, listed in schedule 5A of the Fisheries Regulation 2008. Eighteen species, genera or families of fish are declared noxious fish in Queensland. Three of these – carp, tilapia and gambusia—have established and become a significant pest. Noxious fish cannot be kept, hatched, reared or sold.
