  • The southern boundary runs eastwards along the fire line Ride-6 up to Pekua River where it runs at 90 degrees southwards till it meets the fire line Ride-3.
  • Historically the area was a part of the migratory route of the faunal species from Himalayan Mountain, Indo-Malayan and Indo-Chinese realms towards west and Peninsular Indian realm species to the east.
  • It shares contiguous forest patches of Phibsoo Wildlife Sanctuary and Jigme Singye Wangchuck National Park in Bhutan, creating a trans-boundary conservation landscape of more than 2,400 km2.

Dehing Patkai National Park
