Urgent conservation efforts have ensured that the one-horned rhinoceros has improved its position somewhat. It has gone from the “endangered” to the “vulnerable” category in the International Union for Conservation of Nature’s Red List of Threatened Species. But conservation remains worried. The number of rhinos remains low in India. Guwahati-based naturalist B K Talukdar says that “the current estimates are between 2750-2850 rhinos, of which about 2350-2400 are in India while about 400-500 are in Nepal”. Most of India’s rhinos are in Assam’s Kaziranga National Park. According it the 2010 census, it has 2,048 which is almost 70% of the world’s population of one-horned rhinos. Conservation say it is important to spread the population more widely so that the species survival is not dependent on the Kaziranga rhinos alone. It may be a prudent move. Poachers, another major threat, had wiped out the entire rhino population of Manas National Park in western Assam by the year 2000. It was once home to a hundred rhinos. Right now, a catastrophe in Kaziranga could well spell doom for the species.
