    About Eastern Swamp Deer

    • The population of the vulnerable eastern swamp deer, extinct elsewhere in South Asia, has dipped in the Kaziranga National Park and Tiger Reserve.
      • It decreased from 907 individuals in 2018 to 868 during the Eastern Swamp Deer Estimation on January 10 and 11 to two high floods in 2019 and 2020. 
    • The eastern swamp deer is endemic to Kaziranga and is not the primary prey of the park’s carnivores, primarily the tiger.
    •  Its population is crucial for the ecological health of the tiger reserve and the encouraging sign is the animal has now moved to other areas such as Orang National Park and Laokhowa-Burachapori wildlife sanctuaries.
