English: The greater one-horned rhino is the largest of the rhino species. Once found across the entire northern part of the Indian sub-continent, rhino populations were severely depleted as they were hunted for sport and killed as agricultural pests. This pushed the species very close to extinction in the early 20th century and by 1975 there were only 600 individuals surviving in the wild. Thanks to rigorous conservation efforts, their numbers have increased dramatically since 1975. By 2012, conservation efforts saw the population grow to over 3,000 in the Terai Arc Landscape of India and Nepal, and the grasslands of Assam and north Bengal in northeast India.
