Impact of Vehicular Traffic on Herpetofaunal Mortality in a Savanna Forest, Eastern Sri Lanka

Mortality of wildlife due to vehicular traffic is among the direct impacts when natural habitats are dissected with roads. This study presents the herpetofaunal mortality on a 3km stretch of a highway crossing Nilgala Forest Area (NFA), a savanna dominated forest in Nilgala, eastern Sri Lanka. A total of 72 species of herpetofauna including 53 reptiles and 19 amphibians were recorded as road kills of which 19 species (26.3%) are endemic to Sri Lanka and 22 species (30.5%) are threatened nationally. A total of 552 road killed individuals (23.6% of tetrapod reptiles, 40.2% of serpentoid reptiles and 36.2% amphibians) were recorded over 48 days.
