Listed as Least Concern because, although the distribution is limited, there are no current threats, it has a stable population, and it occurs in a well-protected area.
|Previously published Red List assessments:|
|Range Description:||This species was previously known only from Mount Isarog on southeastern Luzon Island, Philippines. It has now been confirmed as also occurring on Mount Malinao (Philippines Red List Assessment Workshop May 2017). Its elevational range is 650–1,800 m asl and the extent of occurrence (EOO) of this expanded range is 640 km2.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is common in mid- to upper-montane forests on Mount Isarog. The population appears to be stable.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This species inhabits arboreal microhabitats in mossy and montane rainforests, and deposits its eggs on leaves in shrub layer vegetation. It breeds by direct development.|
|Continuing decline in area, extent and/or quality of habitat:||No|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||Of the two sites at which the species occurs, Mt. Isarog is presently a generally well-protected locality where the species is not highly threatened by habitat loss. Geothermal energy is generated on the slopes Mt. Malinao, but its impact is limited and one of the plants was recently decommissioned due to decrease in steam supply (Philippines Red List Assessment Workshop May 2017). Both sites where the species is known to occur are dormant volcanoes, however it is not thought to be at risk of extinction from future volcanic activity.|
This species occurs in Mount Isarog National Park.
The most important conservation measure needed at present is the continued management of Mount Isarog National Park.
There is also a need for continued monitoring of the population status of this species.
