Scientific Name:	Stumpffia helenae
Species Authority:	Vallan, 2000

Assessment Information [top]

Red List Category & Criteria:	Critically Endangered B2ab(iii) ver 3.1
Year Published:	2004
Assessor/s:	Denis Vallan, Christopher Raxworthy
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Contributor/s:
Justification: Listed as Critically Endangered because its Area of Occupancy is probably less than 10km2, all individuals are in a single sub-population, and the extent of its forest habitat in the Ambohitantely Special Reserve is declining.

Geographic Range [top]

Range Description:	This species is known only from two small habitat fragments in the vicinity of Ambohitantely, in central Madagascar, at 1,500m asl. Surveys at other potential localities on the high plateau have yet to reveal any additional populations (Andreone et al . 2008).
Countries:	Native: Madagascar

Population [top]

Population:	It is very rarely found.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It is a terrestrial species, inhabiting montane forest, and has not been found in altered habitats. Breeding is unknown, but is likely to be similar to that of Stumpffia gimeli (terrestrial nests with non-feeding larvae).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	The forest is disappearing very rapidly at its only known locality due to the impacts of fire, illegal woodcutting by local people, and overgrazing by livestock. No other suitable habitat is found anywhere nearby. As of 2006, habitat loss was continuing, and this species will disappear unless this can be addressed (D. Vallan pers. comm.).

Conservation Actions [top]

Conservation Actions:	It occurs in the Reserve Speciale d'Ambohitantely, which is very poorly protected. Improved management and protection of the remaining habitat of this species is clearly urgently needed.
