Increasingly, global trade and communication are directly contributing to the introduction of plants and animals to areas where they do not naturally occur. These species taken to new environments may fail to survive but often they thrive, and they become invasive. This process, together with habitat destruction, has been a major cause of extinction of Australian native species in the past few hundred years.
Introduced pest animals place considerable pressure on native plants and animals. While some impacts have been well documented, the true impact of pest animals on Queensland’s environment is unknown and difficult to quantify. Foxes and feral cats, which prey on native fauna, have been implicated in the decline or extinction of at least 17 native species.
