Vertical Elevation 40m to 120m (Brahmaputra River Basin)
Dietary Ecology Saccharum grasses, aquatic reeds, marsh vegetation, tree leaves
Population Status Increasing through strict anti-poaching security

Species Overview & Morphology

Bearing thick armor-like skin folds with distinctive rivet-like tubercles, the Greater One-Horned Rhinoceros is an ancient survivor of the Pleistocene megafauna. Concentrated in Assam's Kaziranga National Park, these solitary behemoths thrive along the wild floodplains of the Brahmaputra River.

Ecological Role & Canopy Dynamics

Through wallowing in marsh depressions, rhinos maintain vital wetland pools and dhand lakes that support juvenile fish, migratory waterfowl, and endangered Asian water buffalo during annual flood surges.

Field Expedition Journal Notes

Ground-Truthed Field Behavior

"During annual monsoon submergence in Kaziranga, ranger patrols recorded rhinos swimming across five-kilometer flood channels to reach highland refuge knolls constructed along the Karbi Anglong boundary."
