Exotic vertebrates introduced into Australia have established wild pest populations that cause hundreds of millions of dollars of harm to agriculture each year plus untold harm to Australian native species and ecosystems.
Introduced species can compete with stock and native animals for food, water and nest sites, cause severe land degradation through overgrazing and browsing on young trees and shrubs, and kill, maim or harass native species and livestock.
Unfortunately, if they escaped or were illegally released, there is a risk that new exotic species that are imported and kept in zoos or as pets could establish wild pest populations in Australia.
If these new species start to breed in the wild and spread, their eradication will become virtually impossible. This report examines the factors that can be used to distinguish between species that pose a high risk of becoming a new pest and those that pose a lower risk. This information is used to construct a scientifically based risk assessment model to evaluate the risks posed by the import and keeping of exotic species in Australia.
This report is essential reading for all people with an interest in protecting Australian agriculture and native species and ecosystems from future damage by additional exotic invasive species. It provides information and guidance that will assist those responsible for assessing and managing the risks posed by the import and keeping of exotic vertebrates, including government policy makers, quarantine officials and wildlife managers.
