From the IUCN Red List Species Account:

 

Range Description

This species is widespread on Luzon, Polillo, Palaui and Catanduanes Islands, in the northern Philippines where it occurs between 0–600 m asl, and is expected to occur more widely between known localities (A. Diesmos pers. comm. March 2018). It is also found on Marindugue Island (A. Diesmos unpubl. data March 2018).

Habitat and Ecology

It is found in lower montane and lowland forests, riverine habitats, and natural and artificial lakes and ponds. It also thrives in disturbed habitats such as flooded rice fields and villages, that are adjacent to forests (A. Diesmos pers. comm. March 2018). It breeds by larval development.

Population

It is common to abundant in many natural and anthropogenic habitats. Its population is considered to be stable.

Population Trend

stable

Major Threats

The major threat is habitat loss due to small-scale shifting agriculture, expanding human settlements, wood collection for firewood and charcoal production, and illegal logging by commercial entities. In addition, the construction of a major east-west road was completed in 2016 through the western part of Isabela Province on Luzon and the presence of the road is anticipated to intensify illegal logging activities (Philippines Red List Assessment Workshop May 2017). In addition, nickel, chromite and gold mining are taking place within the Northern Sierra Madre and the Central Cordillera, as well as limestone and sand quarrying (Philippines Red List Assessment Workshop May 2017). The pollution of streams and rivers from agricultural pesticides, herbicides, and mine-tailings are concerns, as well as harvesting for human subsistence. Chytrid has been detected in this species, however infection levels were generally low (Diesmos et al. 2012).

Conservation Actions

Conservation Actions
Its range includes many protected areas. Conservation measures are not needed for this adaptable species at present. However, since the 2004 assessment, in collaboration with various regional academic institutions, NGO-led awareness campaigns have been taking place to educate the public regarding the need to protect remaining forests on Luzon Island, resulting in positive responses by local communities and improved protection for priority species.

Research Needed
Further information is needed on this species' taxonomy, distribution, population status and trends. Research is needed to determine whether or not harvesting is a major threat.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern in view of its wide distribution, tolerance to a degree of habitat disturbance, and presumed large population.

Taxonomic Notes

This is likely a species complex.
