The area is located close to the coast, between Barumun river and the estuary of Rokan river near Bagansiapiapi.
Bird diversity in the area is not yet assessed through intensive study, only some rapid observations by A. Elliot and I. Martinez (look at Holmes 1996). Probability the Spot-billed Pelican Pelecanus philippensis breed in this site at Daun River. This bird maybe extinct in South-east Asia. The survey also found Lesser Adjutant Leptoptilus javanicus, described as common bird at the estuary of Rokan River, of which the population is under serious threat from hunting.The other survey by van Balen (1991) reported the existence of some important bird species such Storm's Stork Ciconia stormi, Large Green-Pigeon Treron capellei and probably Spotted Wood-owl Strix seluputo which need to reconfirmed.This area is probably important for mangrove specialist bird species.
