Lying
    along the mighty Brahmaputra River, the Kaziranga National Park covers an
    area of about 430 sq. km. Its swamps and grasslands with tall thickets of
    elephant grass and patches of evergreen forest, support the largest number
    of rhino in the subcontinent. It was an alarming depletion in their numbers,
    due to hunting and poaching that led to the conservation of this area in
    1926.
