    Climate change Habitat potential Within Australia climate mediated threats; including impacts on alteration future water temperature and availability; are putting the conservation status of two thirds of all freshwater crayfish species at risk (Richman et al.; 2015).
    Climate change may affect the Mt Arthur burrowing crayfish in the future if changes in weather; water and drainage patterns result in broad scale habitat changes.
    Fire Too frequent future High intensity fires; and the consequent effects on vegetation burning and habitat quality; may impact upon the Mount Arthur burrowing crayfish (Doran 2000).
