the area had revealed already low numbers. There are further concerns that the floods displaced snags from waterways which are a vital part of the habitat for the species. Identified important locations The 2006–2010 Giant Freshwater Lobster Recovery Plan highlighted several catchments (or parts of) which had been identified to contain good habitat quality and good crayfish populations and should be considered for conservation efforts. Some areas require renewed evaluation since habitat quality may have changed since surveys were conducted. North-eastern Tasmanian rivers lacked sufficient data to fully determine all areas of importance. 1997 Aitken Creek, downstream of Nook Road to Sheffield Road crossing Black River and tributaries Dip Range streams Duck River catchment above Trowutta Road Emu River tributaries Flowerdale River from the top of the catchment to near Lapoinya Great Forester River and tributaries Inglis River and tributaries Little Forester River and tributaries 2003 Cam River catchment Hebe River (catchment of Flowerdale River) Arthur River catchments including Frankland, Rapid, Keith and Lyons rivers See also Fauna of Australia Flora and fauna of Tasmania Murray crayfish Threatened fauna of Australia Tenuibranchiurus - world's smallest crayfish, also found in Australia References Further reading External links Inland fisheries, fact sheet Todd Walsh and the Giant Freshwater Crayfish video on Youtube The Giant Freshwater Crayfish video on Youtube The Giant Freshwater Crayfish and logging in the Tarkine Parastacidae Freshwater crustaceans of Australia Endangered fauna of Australia Crustaceans described in 1936 Edible crustaceans
