Occurrence patterns of herpetofauna in different habitat types of western Terai Arc Landscape, India

Abstract

The Terai Arc Landscape (TAL) is an important region of biodiversity in India. Situated in the foothills of the Himalaya, it is spread across India and Nepal. We describe the herpetofauna of the western part of TAL encompassing Ramnagar Forest Division, which falls in Uttarakhand state of India. We primarily used visual encounter survey method for sampling. A total of 47 species of herpetofauna belonging to three orders, 17 families and 36 genera were recorded from 10 habitat types (6 terrestrial and 4 aquatic). Highest species richness (n=32) was recorded from the human settlement and least (n=4) species richness was reported from pond habitat. In this paper, the diversity of amphibians and reptiles in each habitat type is discussed.
