| Popis: | Livestock depredation by carnivores cause substantial human carnivore conflict and subsequently decreased support for carnivore conservation. Thus, understanding carnivore diet with respect to wild prey availability has major implications to determine the reasons behind livestock depredation. A study was conducted to investigate food habits and prey use of tiger at four study sites (Dudhwa National Park, Kishanpur Wildlife Sanctuary, Pilibhit Forest Division and Katerniaghat Wildlife Sanctuary) in Dudhwa landscape, Terai Region, North India for further understanding of prey–predator relationship and partial impact of wild prey availability on livestock depredation by tiger through scat analysis. Scat analysis shows that the tigers depend mostly on medium sized prey throughout the study area (74.11, 73.58, 71.79, 47.62%). In Dudhwa National Park and Kishanpur Wildlife Sanctuary, predation was attempted subsequently on wider prey variety of eleven and nine different available prey species where livestock depredation were only 3.77 and 5.36% respectively. While, in absence of wider prey variety, large sized livestock (21.91, 16.55%) and nilgai (24.41, 5.57%) contributed much higher in tiger diet in Pilibhit Forest Division and Katerniaghat Wildlife Sanctuary respectively. Our study suggested that availability of prey variety has an important role in reduced livestock depredation. Medium sized preys were mostly contributing in tiger diet and seems to be a significant parameter for sustaining tiger population where abundance of large sized prey is rare. Conservation of medium sized preys is important but along with natural restoration of the population of large sized prey species like sambar and swamp deer is essential in order to reduce livestock depredation. |
