Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA MICROHYLIDAE

Scientific Name: Ramanella palmata
Species Authority: Parker, 1934

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Kelum Manamendra-Arachchi, Anslem de Silva
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification:
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in the Central Hills of Sri Lanka.

Geographic Range [top]

Range Description: This species is endemic to the central hills of Sri Lanka where it has been recorded at elevations of 1,830-2,135m asl.

Population [top]

Population: It is a rare species.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is generally restricted to montane tropical moist forest habitats. Adults can be found in leaf-litter (and are at least partially fossorial), under stones and other ground cover, beneath bark, on the trunks of trees, and in the canopy. Breeding is thought to take place by larval development, like other members of its genus, but it is not known whether or not it requires water for breeding.
Systems: Terrestrial

Threats [top]

Major Threat(s): The principal cause of decline appears to be habitat loss through the conversion of forests to cultivated land (tea plantations), logging with subsequent replanting of plantation forests (in Pattipola) and droughts and fire (especially in Horton Plains National Park). Die-back of mature trees in Horton Plains National Park and Hakgala Strict Nature Reserve is also a key threat to the species (although the causes of this die-back are not known).

Conservation Actions [top]

Conservation Actions: Besides Horton Plains National Park and Hakgala Strict Nature Reserve, it is also recorded from Agra-Bopats Forest Reserve and Pattipola Forest Reserve. Further research is needed to investigate the breeding biology of this species, and also to understand the reasons for the die-back of mature trees in some of its key protected habitats.
