Habitat:
The primary habitats for this fossorial species are lower montane and lowland forests, including streams and rivers. This species calls in large choruses in temporary pools following heavy rains (June–August) and breeding occurs in ephemeral pools (Brown et al. 2013). It is commonly found in disturbed habitats, such as agricultural land, rice paddies and gardens, adjacent to forested areas (A. Diesmos pers. comm. May 2017). It is known to occur at high abundances in disturbed habitats at many sites, provided that surveys are conducted at the beginning of the rainy season following heavy rains, when individuals emerge from the ground to breed (Brown et al. 2012).

Range:
This species is found in the mountains of the Central Cordilleras and Sierra Madres of northern Luzon Island, in the Philippines. It is restricted to elevations from 700–1,800 m asl in the Cordilleras, but has been found from sea level to 600 m asl in the Sierra Madres (Alcala and Brown 1998, Diesmos et al. 2014). This species is much more widely distributed than originally assumed (Brown et al. 2012).

Conservation:
Conservation Actions
The species' range overlaps with the boundaries of several protected areas on Luzon Island and some of these are well-managed by the Department of Environment and Natural Resources in partnership with local government units. Since the 2004 assessment, in collaboration with various regional academic institutions, NGO-led awareness campaigns have been taking place to educate the public regarding the need to protect remaining forests on Luzon Island, resulting in positive responses by local communities and improved protection for priority species. 

Conservation Needed
Improved enforcement of protected area boundaries and appropriate management practices are required to safeguard the remaining habitat, as well as ongoing awareness campaigns to raise public support.

Research Needed
More information is needed on this species' population size, distribution, and trends, and additional taxonomic research is recommended in light of the cryptic species present in this complex.
