From the IUCN Red List Species Account:

 

Range Description

This species is known from Biliran Island, Leyte Island, several montane localities on Mindanao Island, and Siargao Islands, in the Philippines (Philippines Red List Assessment Workshop May 2017). It is expected to be found on intervening islands. Its elevational range is unknown.

Habitat and Ecology

This species inhabits arboreal microhabitats in mossy forest, but has also been found in disturbed lower montane forest. Male calling aggregations have been observed beside ponds and lakes. It is known to breed by direct development and does not require water for breeding.

Population

It is common in suitable habitat. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

The major threat is the destruction and conversion of both lowland and montane rainforest habitat on Mindanao due to small-scale agricultural activities, large-scale oil palm plantations, wood collection for charcoal production and expanding human settlements (Philippines Red List Assessment Workshop May 2017). There is also nickel, chromite, and gold mining, and limestone and marble quarrying in eastern Mindanao.

Conservation Actions

Conservation Actions
Some subpopulations of this species are protected in national parks, such as Mount Malindang National Park. 

Conservation Needed
There is a need for increased protection of remaining forest habitats on Mindanao.

Research Needed
More information is needed on this species' distribution, population status, ecology, and threats. A comprehensive appraisal of the genetic and morphological variation of the genus is needed (Sanguila et al. 2016).

Red List Status

Vulnerable (VU)

Rationale

Listed as Least Concern in view of its wide distribution and presumed large population.
