This species is known from several areas in Java, including two areas in Jawa Barat, Guci and Mount Slamet in Jawa Tengah, one area in Jawa Timur, seven sites within Gede Pangrango National Park, six sites within Halimun Salak National Park, the forest around the Taman Safari Indonesia Zoo in Cisarua, West Java, Cibodas Botanical Garden, Telaga Warna and Mount Merapi National Park, Java, Indonesia (M. Kusrini pers. comm. August 2009). It is known to occur from 900–1,795 m asl (M. Kusrini pers. comm. August 2009).
Habitat and Ecology
This species lives in lowland and montane forest, including in disturbed forest providing there is canopy cover which can be provided by trees (do not always have to be high trees) and bushes (Indonesia Red List Assessment Workshop May 2017). It breeds in streams. One female was found to contain 180 eggs (M. Kusrini pers. comm. August 2009).
It is a common species in suitable habitat, and is more common in the higher elevated areas which are forested (Indonesia Red List Assessment Workshop May 2017). Between February-June 2014, surveys in Telego Muncar and Turgo Hill at Mount Merapi recorded this species (D. Satria pers. comm. May 2017). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
The major threat is the loss of forest habitat due to smallholder farming and subsistence wood collecting. More recently, this species has tested positive for Batrachochytrium dendrobatidis (Kusrini et al. 2008), although there are no reports of associated declines in this species.
This species occurs in Mount Merapi, Gunung Halimun and Gunung Gede Pangrango National Parks, as well as in the Taman Safari Park.
Further habitat protection is required.
It is important to assess the presence and extent of the impact of the chytrid fungus on frog populations in Indonesia (Kusrini et al. 2008).
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its relatively wide distribution and presumed large population.
