| Abstract: |
We estimated tiger and wild prey abundance in the Bardia National Park of Nepal.
Tiger abundance was estimated from camera trap mark recapture in 85 days
between December, 2008 to March, 2009 by placing 50 camera trap pairs in 197
trap locations with a sampling effort of 2,944 trap nights. We photo captured 16
individuals (≥1.5 year old) tigers identified on the basis of their unique stripe patterns.
The number and density (per 100 km2) of tiger was 19 (SE 3.3) and 1.31 (SE 0.32),
respectively. Distance sampling was used to assess the prey abundance on 170
systematically laid line transects between May–June, 2009. The density of all the
wild prey (individuals/km2) was 56.3 (SE 6.5). The density (individuals /km2) of Chital
was 29.3 (SE 4.3). The density of barking deer, wild pig and sambar were in higher
to medium, medium and medium to low range as compared to other protected areas
in South Asia respectively. The study indicated decline of tiger in Bardia National
Park even though the existing level of the prey population appears to be adequate
to support higher tiger numbers. There is hope of meeting the ambitious goal of
doubling the tiger population by 2022 set by the Tiger Range Countries which was
evident in 2014 with 50 tigers in Bardia National Park and Khata Corridor. The tiger
habitats outside the protected areas should be managed with the local community-
based initiatives to ensure the acceptance of low density tiger movement.
