This species was previously only known only from Mount Banahaw, on Luzon Island, in the Philippines. Its range has now been extended to Mount Bataan and Zambales Mountain Range (Philippines Red List Assessment Workshop May 2017). Its extent of occurrence (EOO) is 9,980 km2 and all individuals are considered to occur in three threat-defined locations.
Habitat and Ecology
This species inhabits arboreal microhabitats in mossy and montane rainforests. It deposits its eggs in shrub layer vegetation, in tree ferns, aerial ferns and pandanus. It breeds by direct development.
It is very common above 800 m asl on Mount Banahaw, and the population appears to be stable.
There are low levels of deforestation at high elevations where this species occurs (Philippines Red List Assessment Workshop May 2017). Mount Bataan is a dormant volcano, though volcanic eruptions may pose a potential future threat to the subpopulation occurring there. The main threat to the subpopulation in the Zambales Mountain Range is chromite mining.
This species occurs in Mount Banahaw-San Cristobal National Park and Bataan National Park.
The most important conservation measure needed is the continued management of the national parks.
More information is needed on this species' distribution, population status, ecology, and threats.
Red List Status
Listed as Vulnerable, as this species has an extent of occurrence (EOO) of 9,980 km2, it occurs in three threat-defined locations, and there is continuing decline in the quality of its habitat on Luzon Island in the Philippines.
This is a species complex comprised of at least two evolutionary lineages (Philippines Red List Assessment Workshop May 2017).
