Visitation Pattern of Mammalian Communities at Waterholes in Tadoba-Andhari Tiger Reserve

Abstract

Waterholes are an important component of management practices in wildlife conservation, especially in arid and semi-arid regions. It is of high conservation and management significance as it is a spatially restricted resource for wildlife. I studied visitation pattern of mammals at 54 waterholes in the core zone of Tadoba - Andhari Tiger Reserve, a dry deciduous forest in the central India. Visitations of mammal species were monitored continuously for four months using camera traps. Visitation frequencies of mammals at the waterholes were checked and compared between winter and summer seasons. Influences of (i) physical attributes of waterholes, (ii) distance between the waterholes and adjacent permanent water sources, (iii) distance to nearest road and (iv) the presence of tourism in the nearest road, on the visitations of mammals at waterholes were studied. It was found that there are differences in the number of visitations, total time spent and the average time spent in a visitation between mammal species and between same species in different seasons. Size of waterholes and artificial water supplementation influenced the visitations of some mammals at waterholes. Overlaps in the temporal visitation patterns of the prey species with that of the predator species were different for ambush predators and pursuit predators.
