by Aug 3, 2021Wildlife, Wildlife Sanctuary0 comments

Yardi-Rabe Supse Wildlife Sanctuary is a protected area in West Siang district of Arunachal Pradesh. Although the Sanctuary has been notified, the rights of the community have not yet been settled fully and there may be some alteration in area also at the time of finalisation. This is basically a data deficient site but extremely important because it has some globally threatened avian species.



This sanctuary was declared in 1996 but the sanctuary boundary was notified in June 2007. However, the rights of the local community are yet to be settled which may eventually alter the boundary of the sanctuary. The sanctuary is administered by the Divisional Forest Officer, Aalo Forest Division.

In order to provide an additional safety zone around the National Park, the Ministry brought out a draft Notification dated 19.02.2016 for declaring an eco-sensitive zone of 27 square kilometres with an extent upto 1 kilometre (North-West) and 500 meter (South-West) around the protected area. There are no villages inside the eco-sensitive zone.
