J Bombay Nat Hist Soc 2002, 99(2), 184-210.
Reports the results from systematic sampling and 6 years of incidental encounters with wild mammals in Indira Gandhi Wildlife Sanctuary, Anaimalai hills in the Western Ghats, Tamil Nadu, India. A total of 239 plots were laid along 38 transects in different vegetation types, covering a length of 200 km. Data was collected during transect walks by direct sightings, whereas the plots were searched for the presence of signs and tracks. Gaur, sambar and muntjac occurred with a higher frequency in rainforest, while chital and pig did so in other vegetation types. Elephants moved in the dry season to the wet western ranges and back in the wet season to the dry eastern ranges. Tiger had a higher frequency in the wet forests, while that of leopard was higher in the drier forest types. The dry forests at lower altitudes were occupied by the common palm civet, while the forested areas of higher altitudes were largely inhabited by brown palm civet, along with the small Indian civet which occurred commonly in the open areas. Malabar giant squirrel had a relatively higher frequency in other vegetation types than in the riparian forests of the eastern ranges, which were inhabited by grizzled squirrel. The forests at lower altitudes were occupied by bonnet macaque and Hanuman langur, whereas the wet forests of the higher altitude were occupied by lion-tailed macaque and Nilgiri langur. The wet ranges in the Sanctuary were characterized by fragmentation of rainforest, and dry ranges had high.
