Siliguri, Dec 02 (ANI): India's northeastern and eastern states demanded assistance from central government for protection and conservation of rhinoceros. A programme to create awareness on conservation of rhinoceros was organised in West Bengal which was attended by various conservationists including chairman of International Union for Conservation of Nature (IUCN), Doctor Bibhab Kumar Talukdar and Chief Conservator of Forests, Ujjal Bhattacherjee. Urging for a scheme for conservation of dwindling species, IUCN chairman Talukdar said last year 41 rhinoceros were killed in Assam. According to the last Rhino census conducted by the state forest department, there are more than 50 rhinoceros in Garumara National Park and more than 200 in Jaldapara, but the number of this unique species is not increasing.
