The number of animal pests declared on the relevant Tasmanian legislation. An animal pest being an introduced animal with an established self-supporting population in the wild (also known as feral or naturalised) that is a threat to human health, primary production and/or the natural environment. Animal pests are among the most serious threats to Tasmania's natural environment. They displace and degrade native species and communities and contribute significantly to land and water degradation. Any increase in the number of animal pest species and/or increase in the abundance and distribution of existing pest species is reflected in degradation of the natural environment. The number of animal pest species declared in Tasmania can be tracked over time to ascertain whether animal pest numbers are increasing or decreasing.
Although only six species are formally declared as pests by legislation in Tasmania, management agencies (such as DPIWE, CSIRO Division of Marine Research, the Inland Fisheries Service) consider a further 100 animal species as pests. Of these 44 are considered to be environmental pests. Environmental pests in Tasmania, 2001.
