Important area for White-winged Duck Cairina scutulata, Storm's Stork Ciconia stormi, and Wallace's Hawk-eagle Spizaetus nanus. This area is a breeding site for at least 400 pairs of heron (probably Purple Heron Ardea purpurea) but the number has decreasing because of over exploitation of egg and juvenile (Burn & Brickle 1992). In 1997 survey by Tim Ekspedisi Cairina scutulata found the White-winged Duck in Geloga.The southern boundary of Indragiri River is very rich with bird diversity. At least 8 species, White-winged Duck Cairina scutulata, 23 Milky Stork Mycterea cinerea,and Lesser adjutant Leptoptilus javanicus found near Kuala Cinaku transmigration area. Kuala Cinaku is the area in Indonesia where Northern Pintail Anas acuta first recorded in November 1992(Burn & Brickle 1992).

(Burn & Brickle 1992, Tim Ekspedisi Cairina scutulata 1997, Colijn 1999, Wibowo & Suyatno 1999).
Habitat and land use
Peat swamp forest (arround 80%) and freshwater swamp forest (Silvius et.al. 1988, Burn & Brickle 1992, Tim Ekspedisi Cairinascutulata 1997, Wibowo & Suyatno 1999). The southern part of this area has been converted for rice field (Colijn 1999).
Pressure/threats to key biodiversity
Forest Clearence, logging, drainage of wetland for settlement that hydrologically unsustainable and shifting agriculture (Silvius et.al.1988, Burn & Brickle 1992, Tim Ekspedisi Cairina scutulata 1997).
Declared as Kerumutan (Baru) Wildlife Sanctuary (120000 ha) based on SK Mentan No. 350/Kpts/Um/6/79 in June, 1979 (Anon 1995, Anon 1998). Proposed to expand this area to 130000 ha (Anon 1995).
