IMCRA Mesoscale Bioregions

The Integrated Marine and Coastal Regionalisation of Australia (IMCRA v4.0) classified Australia's marine environment into ecologically relevant bioregions for regional planning. These bioregions are the basis for the development of a National Representative System of Marine Protected Areas (NRSMPA).
