Roadkill records of two civet species on National Highway 715 passing through Kaziranga-Karbi Anglong landscape complex, Assam, India

Abstract

This study was conducted on a continuous 64-km stretch of National Highway (NH) 715, which bifurcates the Kaziranga-Karbi Anglong landscape complex, with Kaziranga National Park on its southern side and North Karbi Anglong Wildlife Sanctuary on the northern side. The survey was carried out from October 2017 to September 2018 via two-way journeys three days a week, with two observers using a motor vehicle at a steady speed of 25–35 km/hour. Roadkill reports of one Large Indian Civet Viverra zibetha and six Small Indian Civets Viverricula indica were collected. Both the species are solitary and nocturnal, and prefer to inhabit secondary landscapes intermingled with human habitation. This stretch of NH 715 forms a crucial passage for wildlife foraging and breeding, and this study reflects the impacts of roads causing wildlife-vehicle collision for two civet species.
