| Population dynamics and resource selection by tigers in Corbett Tiger Reserve | |
| 2019 Full Book | |
Most of our knowledge on space use and food habits of tigers in India comes from the tropical deciduous forests of western ghats and central India. We looked at space use and food habits of tigers in Corbett, which has high competition for space, high turnover and also high reproductive potential. Cervids accounted for 90% of the tigers diet and Chital (_Axis axis_) was the preferred prey. We used camera trapped based minimum home range estimates for resident male and female home ranges, shifts, expansions/contraction and overlaps. Home range of males (n=15) 16.4 + 1.6 km2 was 5 times more than the home range of females (n=14, 3.9 + 0.8 km2). None of the resident females showed shifts in its home range area while 4 of the males, 2 of them sub adults, showed shifts and home range expansion between 2010 and 2015. We found relatively high overlap between females (16%) than reported by other studies and males had an average overlap of 34%. Smaller annual minimum home range usage areas of the breeders/residents and high female home range overlap than those reported for tigers (see Sunquist 1981, Simchareon et al. 2014 and Chundawat et al. 2016) suggests adjustment in space in response to high competition in CNP. |
