This
study is an attempt to elucidate factors that determine the choice of home area
of the smooth coated otter, Lutra
perspicillata, along the river banks and islands, in the Cauvery Wildlife
Sanctuary. The study was carried out over a period of eight weeks between
January 2002 and mid-March 2002. A
5km stretch was chosen as the intensive study area. Various habitat parameters
were looked for and assessed. It was found that in general, otter sites varied
significantly from non-otter sites. High percentage of loose sand and low
percentage of hard sand seemed to be the important factors governing site
selection by otters. Otters seemed to avoid areas having high levels of human
disturbance. This study has
categorised the preferred habitat of otters, which is of importance to
conservation.
