From the IUCN Red List Species Account:


Range Description

This species is endemic to the Horton Plains and Pattipola, in the Central Hill Country, in Sri Lanka, and occurs from 1,890-2,135m asl (Manamendra-Arachchi and Pethiyagoda 2005).

Habitat and Ecology

It hs been found mostly on shrubs (usually less than 0.3-2m above ground) in montane tropical forest, forest edge (bordering tea plantations) and anthropogenic habitats. It is active by day and night, and at night adult males perch on branches and leaves and vocalize (Manamendra-Arachchi and Pethiyagoda 2005). It breeds by direct development, and is not dependent upon water. The female excavates a deep hole in the forest floor where the eggs are then deposited.


It is common in suitable habitat.

Population Trend


Major Threats

The Pattipola population is threatened by timber harvesting of a plantation near the Horton Plains National Park.

Conservation Actions

It is found in Horton Plains National Park, but there is need for strengthened protection of habitat in the Central Hills of Sri Lanka.
