| Popis: | The Endangered Hog Deer Axis porcinus has experienced drastic population declines throughout its geographical range. There is limited knowledge of its current population status, particularly from northeastern India. In this study the population density of Hog Deer was assessed in Manas National Park, which was a deer stronghold prior to the armed conflict that lasted for almost two decades, resulting in depressed deer populations. With the cessation of conflict, efforts were invested by both government and conservation organisations for the recovery and conservation of charismatic fauna in the park. Studies on Hog Deer populations, however, were lacking and thus reliable information on current status is unavailable. Current population status and threats faced by Hog Deer were assessed to aid informed conservation decisions. Distance sampling techniques (line transects) were applied in the grassland habitat during the dry season of two consecutive years. The estimated Hog Deer density was 18.22±3.32 km-2. The potential threats to Hog Deer identified in Manas include habitat loss, habitat degradation due to spread of invasive plant species, illegal hunting, and other anthropogenic disturbances. Our study suggests that the Hog Deer population, though reviving, needs immediate conservation attention. |
