Elephants in a teacup: Ranging and Habitat-use of Asian elephants Elephas maximus in a Plantation Dominated Landscape in Southern Western Ghats, India

Ranging patterns of four focal herds using a plantation-forest matrix of the Valparai plateau was studied by following the individuals on a regular basis, recording all possible sightings, for five years. Although surrounded by a network of protected areas, the focal herds were found to use the plateau extensively. There was minimal spatial overlap observed between the four herds, except between two, PTH and MON, which showed a fairly large overlap of 130 sq.km. The observed ranges of elephants were smaller (119.71 {+/-} 24.11 sq.km) compared to previous studies on the species in India, but were comparable with those from Sri Lanka. Possible risk avoidance strategy is observed in their use of the landscape, as evidenced by the use of high intensity human activity areas mostly during night than day. Compared to previous studies from the same landscape, there is also an observed increase in the use of natural vegetation (in the form of rainforest fragments) than the plantation and monoculture habitats, indicating the importance of forest remnants for elephants on the plateau. The observations indicate importance of anthropogenic areas outside protected areas as potential habitats and, not just as movement pathways or as temporary refugia. Conservation planning should therefore consider such areas while initiating landscape-level management strategies for the species. The study also highlights the importance of longitudinal observation-based studies in ascertaining ranging, in the absence of logistically challenging techniques such as radio telemetry.
