From the IUCN Red List Species Account:

 

Range Description

This species occurs on Luzon, Leyte, Samar, Mindanao, Bohol, and Siquijor, in the Philippines where it occurs between 0–2,000 m asl (A. Diesmos pers. comm. March 2018). It is expected to occur more widely than currently mapped (A. Diesmos pers. comm. March 2018).

Habitat and Ecology

This species inhabits arboreal microhabitats in lower montane and lowland forests. It has also been recorded from some disturbed areas adjacent to forests. It lays its eggs on leaves, and is a direct developer. It will tolerate some habitat disturbance, but will not tolerate the removal of forest cover (A. Diesmos pers. comm. March 2018).

Population

It is common to very common in forested areas, even in some disturbed areas adjacent to forests. It is one of the most common forest species of Philippine frog and it inhabits a considerably wide geographic and elevational distribution. Its population is considered to be stable.

Population Trend

stable

Major Threats

The major threat is the destruction and conversion of both lowland and montane rainforest habitat due to small-scale agricultural activities, large-scale oil palm plantations, wood collection for charcoal production, and expanding human settlements.

Conservation Actions

Conservation Actions
Its range includes several protected areas.

Research Needed
Taxonomic studies are necessary to determine whether this is a complex of more than one species. More information is needed on this species' distribution, population status and trends.

Red List Status

Least Concern (LC)

Rationale

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

Taxonomic Notes

It is suspected that Philautus surdus is a complex of species and further taxonomic work is required to verify this (A. Diesmos pers. comm. March 2018).
