Assam has proposed the establishment of its 6th national park called Raimona national park. This is to be a part of the Ripu reserved forest – a buffer zone under the Manas National park. This region is significant for housing one of the largest populations of the golden langur, which is listed as an endangered species by the IUCN. This region is known for being ravaged by militancy and encroachment. Other national parks in the region include Kaziranga NP, Dibru Saikhowa NP and Rajiv Gandhi Orang NP.
