Threats to crayfish/koura
Koura/freshwater crayfish
Crayfish populations are decreasing in some areas as they are subject to habitat modification and land intensification.
Predation by introduced species has also played a role as has harvest for human consumption in some places. They are listed as a threatened species and their populations are in gradual decline.
