Group Size and Population Structure of Vulnerable Gaur in an Isolated Tropical Deciduous Forest of Eastern India

Group Size and Population Structure of Vulnerable Gaur in an Isolated Tropical Deciduous Forest... The group size, age and sex ratio of gaur was studied in the Tropical Deciduous habitat of Kuldiha Wildlife Sanctuary, Odisha, eastern India, during 2012–2013. Gaurs were observed by regular monitoring along the motorable roads and forest trails covering a total 3864 km. The overall mean group size and crowding were 6.92 ± 0.02 (SE) and 6.9 respectively which varied significantly between seasons. The sex ratio was skewed to females and there was an increase in adult male ratio during winter season. Calves were observed throughout the year with a slightly peak during December and January. Compared to the gaur population from other regions of India, the group size range in Kuldiha Wildlife Sanctuary is the smaller one, thus indicating a low population density. Therefore, appropriate management intervention is required for long term conservation of the species. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Proceedings of the National Academy of Sciences, India Section B: Biological Sciences Springer Journals

Abstract

The group size, age and sex ratio of gaur was studied in the Tropical Deciduous habitat of Kuldiha Wildlife Sanctuary, Odisha, eastern India, during 2012–2013. Gaurs were observed by regular monitoring along the motorable roads and forest trails covering a total 3864 km. The overall mean group size and crowding were 6.92 ± 0.02 (SE) and 6.9 respectively which varied significantly between seasons. The sex ratio was skewed to females and there was an increase in adult male ratio during winter season. Calves were observed throughout the year with a slightly peak during December and January. Compared to the gaur population from other regions of India, the group size range in Kuldiha Wildlife Sanctuary is the smaller one, thus indicating a low population density. Therefore, appropriate management intervention is required for long term conservation of the species.
