More Info


Known only from three isolated sub-populations in the most upstream 3.7 km of  the headwaters of the Morwell River east branch, a tributary of the La Trobe River in Victoria, at an elevational range of 350-400 m asl. Historically, this species is considered to have been more widespread in the Morwell River system.
Inhabits a small, cool partly shaded freshwater stream (0.5-1.5 m) in a forestry catchment. The stream is shallow, slightly turbid and slow-flowing, with a mostly bedrock and silty substrate and some gravel and sand. Instream cover is provided by rocks, small amounts of timber debris and overhanging vegetation.


Additional threats include threats include increasing fire frequency, fire suppression impacts, and sediment input into streams from soil disturbance during timber harvesting operation. Climate change is also predicted to cause increased the severity and frequency of drought (Raadik 2019)
