This IBA encompasses Mount Bi Dup and Mount Gia Rich in the east of Bi Dup-Nui Ba Nature Reserve on the Da Lat Plateau. The main forest type of this IBA is evergreen forest, of which a large proportion belongs to the mixed broadleaf and coniferous subtype. The area is known for its high levels of plant diversity and endemism. The fauna of the area is also very species rich, and exhibits high levels of endemism.
Mt Bi Dup lies within the Da Lat Plateau Endemic Bird Area (EBA). Seven of the eight restricted-range bird species that occur in this EBA have been recorded at the site in recent times, including Crested Argus Rheinardia ocellata and Collared Laughingthrush Garrulax yersini.
Non-bird biodiversity: Yellow-cheeked Crested Gibbon Nomascus gabrielle and Black-shanked Douc Langur Pygathrix nigripes have been recorded at Mt Bi Dup (Eames and Nguyen Cu, 1994). Globally threatened gymnosperm species that occur at Mt Bi Dup include Fokienia hodginsii, Calocedrus macrolepis, Pinus dalatensis, Pinus krempfii and Podocarpus neriifolius.
Habitat and land use
A large proportion of the evergreen forest at the site belongs to the mixed broadleaf and coniferous forest subtype, containing such coniferous elements as Pinus dalatensis, Calocedrus macrolepis, Fokienia hodginsii and Podocarpus imbricatus.
Pressure/threats to key biodiversity
The overall level of human impact at the site is moderate. Threats to biodiversity at the site include clearance of forest for for shifting cultivation, charcoal production, fuelwood collection, hunting and over-exploitation of non-timber forest products.
Conservation responses/actions for key biodiversity
Between 1993 and 1994, Eames (1995) studied the avifauna of Bi Dup-Nui Ba Nature Reserve.
In 1986, Nui Ba and Thuong Da Nhim were decreed as separate nature reserves. These two proposals were later combined to form the basis for establishing Bi Dup-Nui Ba Nature Reserve. The investment plan for the nature reserve was approved in 1995.
