Hollongapar Gibbon Wildlife Sanctuary

Hollongapar Gibbon Wildlife Sanctuary is in Jorhat district of Assam in India. It is spread over an area of 20.98 sq km (including the area under Military Engineering Services of Indian Army), and is located at about 20 km from central Assam’s Jorhat town, and 5 km from Mariani.

The sanctuary derives its name from the tall hollong (Dipterocarpus macrocarpus), the State Tree, and the hoolock gibbon, India’s only ape.

It has a semi-evergreen forest with wet evergreen patches amidst tea gardens and human settlements.

The sactuary is home to the largest and most vulnerable number of hoolock gibbons besides the Bengal slow loris, the only nocturnal primate in Northeast India.

The Hoollongapar Gibbon Wildlife Sanctuary was earlier known as Hoollongapar Forest during British period in 1881.
