Euastacus kershawi has been assessed as Least Concern (LC). This species has a large distribution, with an extent of occurrence of approximately 20,000 km2, and can be found from close to sea level up to altitudes of 250 m above sea level. However, although it currently has a wide distribution, it is impacted upon by threats such as harvesting and invasive species. Further research is needed to determine the impact of these on the population.
|Range Description:||This species is endemic to Australia. It ranges from Gippsland, Victoria, to 80 km east of Melbourne, a distance of approximately 320 km (Morgan 1986). In addition this species is found south of the Great Divide, from just south of Mt. Hotham in the Wongungarra and Wonangatta Rivers, to the coast (S. Lawler pers. comm. 2008). This is a lowland species that can be found from close to sea level up to altitudes of 250 m above sea level, and its long, narrow distribution cuts across several drainages in eastern Victoria (Morgan 1986). However, the species is morphologically invariable across its lowland range, and there is no information to suggest any level of fragmentation across its range. The estimated Extent of Occurrence (EOO) of this species is around 20,000 km2 (J. Coughran and J. M. Furse pers. comm. 2008).|

In a study conducted from 1987 to 1996, 1063 individuals (with 102 individuals recaptured at least once) were collected in the Bunyip and
|Habitat and Ecology:||This species is found in southerly flowing streams in eastern Victoria. The vegetation along the banks is commonly wet or dry sclerophyll forest, and the species also persists in areas cleared for agriculture providing riparian vegetation remains intact (Morgan 1986). It is a very slow-growing species (Morey 1998). This species is regarded as very tolerant of disturbed or absent riparian vegetation (S. Lawler pers. com. 2008).|
This species is susceptible to the effects of climate change, particularly with regard to altered hydrological regimes and severe weather events. Climate change modeling predicts that southeastern mainland

This species is found in the Alpine National Park, south of the Great Divide (S. Lawler pers. comm. 2008).
