Gunung Niut (1709 m) is an old volcano, located near Sarawak (border between Indonesia and Malaysia in West Kalimantan).
The information about bird in this area based on 10 days observation in 1987 by Prieme & Heegard (1988). Mountain Barbet Megalaima munticola (350 m longer than the distribution detected before), and also Black-breasted Fruit-hunter Chlamydochaera jefferyi, Mountain Wren-babbler Nopothera crassa andMountain Tailorbird Orthotomus cuculatus (500-700 km longer than the distribution detected before). Bonaparte's Nightjar Caprimulgus concreatus has found in lowland forest, and one of three observers recorded in Kalimantan last decade.Birds species in Perissen Mountain range and Poi Mountain range probably present in this area (Smythies 1981), like Long-billed partridge Rhizothera longirostris, Bornean Wren-babbler Ptilocichla leucogramica, Chestnut-capped Laughingthrush Garrulax mitratus, White-browed Shrike-babbler Pteruthius flaviscapis, Pale Blue-flycatcher Cyornis unicolor, Bornean Blue-flycatcher Cyornis superbus, Rufous-tailed Jungle-flycatcher Rhinomyias ruficauda, Everett's White-eye Zosterops everetti, Pygmy White-eye Oculocincta squamifrons.
Non-bird biodiversity: Tupaia gracilis, Tupaia montana, Tupaia splendidula, Hylobates muelleri, Nasalis larvatus,Presbytis rubicunda, Muntiacus atherodes, Pongo pygmeus, Helarctos malayanus and Neofelis nebulosa (MacKinnon et.al, 1996)This area has important botanical value in Kalimantan in NCP (FAO 1982)
Habitat and land use
Lower mountain forest (probably upper mountain forest also present), and at lower slope probably there is no Dipterocarpacea forest and heath forest anymore, some part of the area still covered with lowland forest.Around 60% of this area covered by lowland forest, 10% upper mountain forest and secondary vegetation, & shifting agriculture.About 70% of this area are used for conservation and watershed management, and the remaining area is used for shifting agriculture activity.
Pressure/threats to key biodiversity
Land conversion, illegal logging, animal hunting and infrastructure development.
