This species has been recorded from many localities on Luzon, Catanduanes, Marinduque and Polillo Islands, in the northern Philippines.
Habitat and Ecology
This species inhabits streams and rivers in lower montane and lowland forests, and is also found in forest edge and agricultural areas near intact natural forests.
It is common in appropriate habitats, but has declined in places due to over-harvesting.
The major threats to this species include habitat loss, due to expanding agriculture, logging and human settlements, and the pollution of streams and rivers. Harvesting by local people is also a threat.
The range of this species includes a few protected areas. Conservation measures must include the regulation and proper disposal of pesticides and herbicides, and the protection of the remaining rainforest, especially riverine habitats and gallery forests. Levels of human exploitation of this species need to be investigated to determine if harvesting from the wild needs to be managed more sustainably.
