Mountain Spiny Crayfish – Euastacus crassus. This crayfish species is located in creeks and small waterways between 600 m and 1000 m elevation in Namadgi National Park and other areas. Its habitat is thought to be restricted to the cooler upper reaches of drainages in the ACT, NSW and Victoria, and the species is considered fragmented across its range, due to the isolating effects of unsuitable warmer lowland habitat. No population data are available for Euastacus crassus in the ACT and little is known about its biology. It is not listed as endangered or vulnerable under the Nature Conservation Act 2014. It is, however, on the IUCN Red List of threatened species and listed in Victoria. A current project is under way to survey for this species to determine its distribution in the ACT.
