Ba Na Nui Chua Nature Reserve is situated on Mount Ba Na, a 1,487 metre-high mountain on the border between Da Nang city and Quang Nam province. Mount Ba Na is situated to the south-east of the mountain ridge that stretches across central Vietnam, from the Annamite mountains to the Hai Van pass. However, Mount Ban Na and the montane habitats it supports are isolated from this ridge by intervening areas of lower elevation.Streams and rivers originating in the north-west of the nature reserve feed the Ca De river, which flows into the north of Da Nang bay, while those originating in the south and east of the nature reserve feed the Yen river, which flows into the south of the bay.
The main natural vegetation types present at Ba Na-Nui Chua Nature Reserve are lowland evergreen forest and lower montane evergreen forest. The lowland evergreen forest is characterised by the presence of tree species in the Dipterocarpaceae family, which are absent from the lower montane forest. The lower montane evergreen forest is dominated by species in the Lauraceae, Fagaceae and Podocarpaceae families. Areas which have been cleared of forest support secondary vegetation. The summit of Mount Ba Na was cleared of forest by the use of herbicides during the Second Indochina War and now supports grassland.
543 species of vascular plant have been recorded at Ba Na-Nui Chua Nature Reserve. These include 12 species listed in the Red Data Book of Vietnam: including Dalbergia cochinchinensis, Decussocarpus fleuryi, Melanorrhoea usitata and Dipterocarpus grandiflorus.
61 mammal species, 178 bird species and 17 reptile species have been recorded at Ba Na-Nui Chua. Many of the species listed in the investment plan were also recorded during surveys by Frontier-Vietnam in 1994 and 1995, which recorded 472 vascular plant species, 29 mammal species, 106 bird species, 20 reptile species, six amphibian species, 33 fish species and 126 butterfly species. Further survey work is required, however, to determine the current status of species of conservation concern at the site.
The forest at Ba Na-Nui Chua Nature Reserve protects the watersheds of the Ca De and Yen rivers. These rivers are an important source of water for irrigation, and domestic and industrial use in Da Nang city.
In 1919, the French colonists established a hill station at the summit of Mount Ba Na. In recent years, a tourism resort has been re-established at the site, with hotels, guesthouses, a cable car and a road to the summit of Mount Ba Na.
