Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Arvin Diesmos, Angel Alcala, Rafe Brown, Leticia Afuang, Genevieve Gee, Katie Hampson, Mae Leonida Diesmos, Aldrin Mallari, Perry Ong, Dondi Ubaldo, Baldwin Gutierrez
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat on Luzon and Sibuyan in the Philippines.

Geographic Range [top]

Range Description:This species is found in the mountains of the Central Cordilleras and Sierra Madres, on northern Luzon Island, and on Sibuyan Island, in the Philippines. It ranges from 400-1,000m asl (R. Brown pers. comm.).

Population [top]

Population:It is common in many of the known localities.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It inhabits the forest floor litter of montane and lowland rainforests, and breeds by direct development. The males form calling aggregations.

Threats [top]

Major Threat(s): The major threat is the loss of lowland rainforest due to small-scale logging and conversion to agricultural land.

Conservation Actions [top]

Conservation Actions: Its range includes a few protected areas, but there remains a need for improved protection of remaining forests in the Central Cordilleras and Sierra Madres on Luzon. As its species name suggests, this is one of the smallest frogs in the Philippines (as small as 15mm in snout-vent length), and so could represent an important flagship species for conservation efforts in the region. There is also a need for further taxonomic research to resolve what might be a species complex.
