Site description The highest point in this area is peak of Gunung Leuser (3450 m), and also the second highest point in Sumatra. Beside that, there are some areas that have elevation above 3000 m . Lembah Alas, with the highest point of Gunung Bendahara (2997 m), is also part of this area.Orang Utan Rehabilitation Centre in Bahorok-Bukit Lawang (North Sumatra) is visited by many tourists. Research station in Ketambe and National Park Head office located near Kutacane. Other popular activities are birdwathing and rafting in Alas River from Ketambe to Singkil (Griffiths 1992, Rijksen & Griffiths 1995)
Key Biodiversity This area contains lowland and mountain bird species. However some mountain species recorded in Gunung Kerinci, such as Schneider's Pitta Pitta schneider, Black-crowned Pitta Pitta venusta, and Sumatran Cochoa Cochoa beccarii are not recorded in this area. Other two species from this site, Hoogerwerf's Pheasant Lophura hoogerwerfi and Mountain Serin Serinus estherae, are not distributed to southern part of Sumatra. Based on newest data, Mountain Serin Serinus estherae is also found at Samosir Island, Lake Toba, as a result the distribution range not only in Gunung Leuser peak as mentioned in Marle & Voous (1988).Bird information from Kluet as part of this area from C.P. van Scahik (in litt. to D. Holmes, March 1993), mentioned that this area probably important for White-winged Duck Cairina scutulata population. Masked Finfoot Heliopais personata also reported in this area (Holmes 1996).Three days survey at Besitang by Chris Shepherd not found any important species (April 1999), but with some additional survey time more species are expected to be found in this area. Tropicoperdix charltonii which has been found near Kuala Simpang (300 m asl) probably also lives in this area. Trichastoma buettikoferi found at 100 m elevation at Bahorok, near to this area.
