All about Hollangapar Gibbon Sanctuary
The Northeast Frontier Railway (NFR) plans to construct canopy bridges in Assam’s Hollangapar Gibbon Sanctuary to help India’s only ape, the hoolock gibbon, safely cross railway tracks dividing its habitat.
The sanctuary, home to about 125 gibbons, faces fragmentation due to a railway track. These bridges, designed by the Wildlife Institute of India (WII) and NFR, will facilitate the arboreal species’ movement. Safety measures, including nets, will be implemented to prevent accidents.

The Hollongapar Gibbon Sanctuary, formerly known as the Gibbon Wildlife Sanctuary or Hollongapar Reserved Forest, is an isolated evergreen forest in Assam, India. Established in 1997, the sanctuary was initially set aside in 1881, with its forests once extending to the Patkai mountain foothills. It is home to India’s only ape and gibbon species, the hoolock gibbons, and the Bengal slow loris, Northeastern India’s only nocturnal primate. The forest’s upper canopy is dominated by hollong trees, the middle by nahar trees, and the lower by evergreen shrubs and herbs.
