Things to Know

About the Park

Declared a sanctuary in 1997 by the Assam Government, the Hollongapar Gibbon Wildlife Sanctuary was at one time interconnected with the Nagaland forests. Tea gardens and human settlements however have now fragmented and isolated this Sanctuary from other forests. Railway lines passing through the sanctuary have further fragmented the Sanctuary and are responsible for animal deaths too. Other threats include tree felling and encroachment.
