Threats

Major Threats
Dams across the region may impact upon the species habitat through changes to the flow regime of the river; the species has been found after the construction of dams, so the degree of impact is uncertain (the species is not a long distance migrant). Pollution from agriculture, industry and urban areas are additional threats.
