It is moderately common in suitable habitat.
There is a high level of human disturbance and habitat destruction in the range of the species due to infrastructure development for tourism and human settlements, agricultural expansion, and water pollution from agricultural activities and human settlements.
The species is not known to occur in any protected areas, making protection and maintenance of remaining habitat an urgent priority.
