From the IUCN Red List Species Account:


Range Description

This species is endemic to the Central Hills of Sri Lanka at elevations of 1,555-2,135m asl. There are records from Agra Bopath and Horton Plains (Manamendra-Arachchi and Pethiyagoda 2005).

Habitat and Ecology

It inhabits both closed and open canopy habitats, including grasslands. Most sub-adults and juveniles were found in grassland and disturbed habitats, while mature males and larger females were usually found in closed-canopy habitats. Adults have been observed perched on branches 0.5-3.5m above ground (Manamendra-Arachchi and Pethiyagoda 2005). It breeds by direct development, and the eggs are deposited in humus.


Anslem de Silva (pers. comm.) reports that the population in the Horton Plains National Park may occur at a density of around 62,000 individuals per kmĀ², which suggests that the species is abundant where it occurs.

Population Trend


Major Threats

The major threats are habitat loss, through the commercial harvesting of timber (clear-cutting) and firewood collection, agrochemical pollution, and the desiccation of habitat through periods of drought. In Horton Plains National Park, forest fires and dieback of mature trees are also threats.

Conservation Actions

It has been recorded from Horton Plains National Park, Agra Bopath Forest Reserve and Hakgala Strict Nature Reserve.

Taxonomic Notes

This species is sometimes placed in the genus Rhacophorus.
