Mammalian diversity of Debrigarh Wildlife Sanctuary, Odisha, India

Abstract

Camera traps were deployed at 123 stations in an area of 346.91 km2 in Debrigarh Wildlife Sanctuary between 25 August 2018 and 29 December 2019 that provided the effort of 3,150 trap-days. Of the 2,767 photo captures, 1,304 were mammals belonging to 13 families and 27 large and medium-sized mammals were recorded in the study area. Carnivores were especially diverse, with 11 species recorded with particular four felidae including Tiger Pantera tigris, Leopard Panthera pardus, and globally threatened Rusty-spotted Cats which extended the range of this species. Leopard was the most captured species with the highest relative abundance (RAI = 5.68) among the carnivore species, whereas the Indian Pangolin Manis crassicaudata (RAI = 0.06) had the lowest abundance. We provide photographic evidence of mammalian species and highlight the importance of conservation of dry deciduous forests for threatened and vulnerable species in the study area. The current camera trap survey is expected to help in the formulation of management strategies for long-term conservation of mammalian species in Debrigarh Wildlife Sanctuary.
