Scientific Name:	Ansonia muelleri
Species Authority:	(Boulenger, 1887)

Assessment Information [top]

Red List Category & Criteria:	Vulnerable B1ab(iii) ver 3.1
Year Published:	2004
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)
Contributor/s:
Justification: 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 Mindanao and Dinagat in the Philippines.

Geographic Range [top]

Population [top]

Population:	It is fairly common where it occurs, but it has a patchy distribution.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It inhabits cool mountain streams and rivers in montane rainforest where it also breeds and the larvae develop.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	This species inhabits high-elevation forests, which are generally less threatened by habitat conversion, agriculture, and human encroachment, and the pollution of streams and rivers. Regardless, some populations of this species are subject to these threats.

Conservation Actions [top]

Conservation Actions:	It is known from several protected areas, including Mount Malindang National Park. Conservation measures must include the regulation and proper disposal of pesticides and herbicides, and the protection of the remaining rainforest, especially high-elevation riverine habitats and gallery forests, on Mindanao. The taxonomic status of this species requires further study.
