Inside the Kaziranga National Park and tiger reserve, spread over a mammoth 1,055 square kilometre area, forest guards in country boats are braving the dangerously high flood waters to keep a watch on wild animals that inhabit this sanctuary and to keep the poachers away. Stretched across the Brahmaputra floodplains, Kaziranga is home to tigers, elephants and the world's largest population of Indian one-horned rhinoceroses.
