Waterholes play a crucial role in wildlife habitats, serving as a determining factor
in maintaining a healthy ecosystem for wildlife. In the core area of the park, a
total of 179 artificial waterholes were constructed to provide water to various
wildlife species, with 24 of them selected for this study. The research utilized
camera trapping, signs surveys, and direct observation methods. The camera
trapping survey revealed that 17 different wildlife species frequented the artificial
waterholes, and among them, 11 were identified as prey species for tigers.
Interestingly, the study found that tigers primarily utilized artificial waterholes
during the night or at dusk, while prey species used them both day and night.
Tigers were recorded in seven different artificial waterholes, with pugmarks
observed in an additional eight. In contrast, prey species were recorded in all
selected artificial waterholes. Notably, the study identified a unique pattern of
waterhole usage, with both tigers and their prey species sharing waterholes
without temporal partitioning. Among the waterholes, those in grasslands were
more frequently used by the prey base compared to others. Additionally, a
greater diversity of wildlife species was recorded in the grassland waterholes.
Based on these findings, it is recommended to conduct an in-depth study to
explore the temporal and spatial aspects of the prey-predator waterhole usage
relationship in Bardia National Park.
