Range Description

This species is known from Basilan, Bohol, Camiguin Sur, Dinagat, Samar, and many parts of Mindanao Island, in the southern Philippines. It is now also known to occur on two additional islands: Siargao and Bucas Grande (Philippines Red List Assessment Workshop May 2017). Following genetic and morphological analysis, a subpopulation from Mount Busa in southern Mindanao which was previously thought to belong to this species has now been assigned to Pulchrana guttmani (Brown 2015). It probably occurs more widely than current records suggest, especially in areas between known sites and additional sites. The elevation range is sea level to 1,500 m asl.

Habitat and Ecology

This species is an inhabitant of undisturbed and disturbed streams and rivers in montane and lowland forests. It breeds and lays its eggs in mountain streams, and the tadpoles develop in water.

Population

It is common in unpolluted rivers and streams and is also, at times, common in disturbed habitats, lakes and waterways in deforested areas. Its population is generally stable.

Population Trend

stable

Major Threats

Important threats to this species are the loss of the lowland rainforest due to human settlements, agriculture and logging, and the pollution of mountain streams and rivers especially due to agricultural effluents.

This species has tested positive for Bd, although no ill effects or mortalities have yet been observed (Diesmos et al. 2012).

Conservation Actions

Conservation Actions
It occurs in several protected areas, including Arakan Valley Conservation Area and Mount Hamiguitan Range, and Mount Malindang Natural Park.

Conservation Needed
The most important conservation measure needed at present is the protection of the remaining tracts of intact lowland rainforest across the Philippines and effective management of these areas.

Research Needed
More information is needed on this species' population size, distribution, and trends.

Red List Status

Least Concern (LC)

Rationale

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

Taxonomic Notes

This is a restricted concept of this species following the split of the broader concept into this and Pulchrana guttmani (Brown 2015).
