Site details


Site description: This IBA comprises Chu Yang Sin Nature Reserve. Chu Yang Sin Nature Reserve encompasses a range of high mountains in the northern part of Da Lat plateau. The nature reserve is centred on Mount Chu Yang Sin, which, at 2,442 m, is the highest point on the Da Lat plateau.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that meets the thresholds for at least one criterion described in the Global Standard for the Identification of KBAs. The site has been reviewed and re-confirmed as a KBA in the process of compiling the revised 2011 CEPF Ecosystem Profile for the Indo-Burma Hotspot.
Additional biodiversity: Chu Yang Sin Nature Reserve is situated within the Da Lat Plateau Endemic Bird Area. Eight restricted-range bird species have been recorded at the site, the most important of which, from a conservation perspective, are Grey-crowned Crocias Crocias langbianis and Garrulax yersini, which are classified as globally endangered. Chu Yang Sin Nature Reserve is one of only two sites known to support a population of Grey-crowned Crocias Crocias langbianis. On the basis of current evidence, it appears that C. langbianis is restricted to a narrow altitudinal range between 900 and 1,200 m. The species appears to have highly specific ecological requirements (Eames et al., 1995), and is therefore likely to be sensitive to habitat modification. Non-bird biodiversity: The following threatened primate species are reported to occur at Chu Yang Sin Nature Reserve by Anon. (1997): Pygmy Loris Nycticebus pygmaeus, Stump-tailed Macaque Macaca arctoides, Long-tailed Macaque Macaca fascicularis, Rhesus Macaque Macaca mulatta, 'Silvered' Langur Trachypithecus villosus, Black-shanked Douc Langur Pygathrix nigripes and Yellow-cheeked Crested Gibbon Nomascus gabrielle. The following species are listed by Anon. (1997) as occurring at Chu Yang Sin Nature Reserve: Asian Elephant Elephas maximus, Gaur Bos gaurus and Southern Serow Naemorhedus sumatraensis.The following gymnosperm species are listed by Anon. (1997) as occurring at the site: Pinus dalatensis, P. krempfii, Fokienia hodginsii and Podocarpus neriifolius.

Habitats


Summary of habitats in KBA: The nature reserve supports lowland semi-deciduous forest below 800 m, montane evergreen forest above 800 m and elfin forest on mountain summits and ridge lines. Coniferous forest occupies areas subject to periodic burning.
