WWF freshwater ecoregions

The WWF published Freshwater Ecoregions of the World, a global map of freshwater ecoregions. The WWF team identified ten freshwater ecoregions for Australia and Tasmania. A major habitat type, or biome, was identified for each ecoregion. The four major habitat types present in Australia are tropical and subtropical coastal rivers, temperate coastal rivers, temperate floodplain rivers and wetlands, and xeric freshwaters and endorheic (closed) basins. The Australian freshwater ecoregions were adapted from the freshwater fish biogeographic provinces identified by Peter Unmack and G.R. Allen, S.H. Midgley, and M. Allen, who were also part of the WWF team. The freshwater fish provinces "were derived through similarity analyses, parsimony analysis, and drainage-based plots of species ranges".Robin Abell, Michele L. Thieme, et al. (2008).
