Replying to a written question, environment minister Jairam Ramesh said nine rhinos were poached in 2006 while 21 and 16 in 2007 and 2008 respectively.

He said the estimated population of rhinos in the four different protected areas of Assam was 2,021 of which 2,048 rhinos were found in Kaziranga National Park, followed by Orang National Park (64 rhinos), Pobitra Wildlife Sanctuary (84) and five in Manas national Park.

"Various committees constituted by the state government have suggested certain measures for the protection of rhinos such as intensification of patrolling, strengthening intelligence network, seeking cooperation of the fringe villagers," the minister added.

The government on its part has been providing financial support under the Centrally sponsored schemes for the conservation and development of wildlife and its habitats including those of rhinos, Ramesh added.
