Abstract
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.
