Estimating mammalian diversity and relative abundance using camera traps in a tropical deciduous forest of kuldiha Wildlife Sanctuary, eastern India

摘要

Information on the status and distribution of species within a geographical region is vital for designing effective conservation plans. We assessed the diversity and abundance of medium to large sized mammals in Kuldiha Wildlife Sanctuary, eastern India by using remotely triggered camera traps from January 2013 to August 2013. A total 916 camera trap days at 65 trap stations were deployed. We recorded 912 independent photographs and identified 20 species of mammals. Based on photographic rate of each mammalian species, the small Indian civet Viverricula indica represented high relative abundance (RAI = 2.07) among the carnivore while the Asian elephant Elephas maximus among the herbivores (RAI = 9.72) and the sloth bear Melursus ursinus among the omnivores (RAI = 2.51). Large carnivores like the leopard Panthera pardus (RAI = 0.55) and the Asiatic wild dog Cuon alpinus = 0.11) were represented by a relatively low abundance. Frequency of various anthropogenic activities from movement of livestock, feral dogs and human traffic accounted for maximum photo capture (combined RAI = 30.7) and found to be negatively correlated with mammalian relative abundance. So an effective intervention incorporating the social and ecological components is desirable for wildlife conservation in Kuldiha Wildlife Sanctuary.
