This species is believed to be endemic to the southern Western Ghats of India, and has been recorded from Kudremukh, Ponmudi and Kalakad. Specimens collected in Maharashtra are misidentifications of Bufo c.f. scaber (S.D. Biju pers. comm.). It has an altitudinal range of 1,000-1,500 m asl.
Habitat and Ecology
It is a terrestrial species primarily associated with montane tropical moist forest, and is presumed to breed in streams. Individuals have been recorded in abandoned eucalyptus plantations. It has not been recorded from agricultural areas.
This is a rare species, and there are no estimates of population size or trends. Populations are fragmented, and the species is believed to be declining throughout much of its range.
The main threat is the conversion of areas of suitable habitat to intensive plantations (tea, eucalyptus and Acacia), and industrial development and urbanization around Ponmudi.
It has been recorded from the Kalakad-Mundanthurai Tiger Reserve (Tamil Nadu) and Kudremukh National Park (Karnataka). The species has been the focus of recent studies (S.D. Biju 1998-2001).
Red List Status
Listed as Endangered because its extent of occurrence (EOO) is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat.
Many museum specimens assigned to Bufo beddomi are misidentifications (Biju 2001).
