List of ecoregions in Australia
Ecoregions in Australia are geographically distinct plant and animal communities, defined by the World Wide Fund for Nature based on geology, soils, climate, and predominant vegetation.
The WWF ecoregions are based heavily upon the Interim Biogeographic Regionalisation for Australia (IBRA) regionalisation. Like the IBRA, it was developed for use as a planning tool for conservation science, with the goal of establishing a system of nature reserves in each of the ecoregions or bioregions sufficient to preserve biodiversity. Both systems also have a prioritization system for establishing preserves; the WWF designated its Global 200 ecoregions as priorities for conservation, and the Department of Environment and Heritage ranks its bioregions high, medium, or low priority, based on "the potential value land reservation in those regions would add to the development of a comprehensive, adequate and representative reserve system for Australia."
