Endemic Bird Areas (EBAs)

Endemic Bird Areas(EBAs) are defined as areas to which at least two restricted-range bird species are entirely confined. BirdLife International has identified seven EBAs in Vietnam:

I/ The Annamese Lowlands.
II/ The Dalat Plateau.
III/ The South Vietnamese Lowlands.
IV/ The Kontum Plateau.
V/ The South-East Chinese Mountains.
VI/ The Lower Mekong Basin.
VII/ The Fansipan Mountain And Northerm Laos.

I/ The Southern Vietnam Lowlands EBA.

The South Vietnamese lowlands are considered here to include the lowlands and foothills Cattien and Tan Phu of Dong Nai Province and southern Lam Dong province. The natural vegetation of this part of the country is tropical semi-evergreen rain forest below c.1,000 m, with tropical montane rain forest.

II/ The Dalat Plateau EBA

This EBA includes the southern part of Vietnam's western highlands which lie within the country's Lam Dong province and adjacent parts of Dak Lak and (probably) Ninh Tuan provinces. Several of the mountains in this area rise to over 2,000 m, the highest being Chu Yang Sin at 2,442 m.
The natural vegetation types of the region are tropical montane evergreen forest, coniferous forest and pine forest. The northern part of the South Vietnamese lowlands lies immediately adjacent to the Da Lat plateau, but the birds of that EBA occur mainly at lower altitudes, in lowland semi-evergreen forest on the flanks of the mountains.

IV/ The Annamese Lowland EBA.

The Annamese lowlands cover the lowlands and foothills of north-central Vietnam (in southern Ninh Binh, Thanh Hoa, Nghe Anh, Ha Tinh, Quang Binh, Quang Tri and Thu Thien Hue provinces) and part of adjacent central Laos.

The natural vegetation of this region is tropical lowland evergreen and semi-evergreen rain forest below c.1,000 m, with tropical montane rain forest above this altitude. However, the coastal lowlands had been deforested almost entirely by 1945, and the forest in the foothills is now highly fragmented and degraded, with few substantial areas of good-quality forest remaining. The EBA has been represented on the map by all land below c.1,000 m within the known historical distributions of the restricted-range species.

This part of Indo-China had, until recently, received relatively little ornithological coverage and the distributions and habitat requirements of the restricted-range species were poorly known. However, surveys by BirdLife International and scientists from the Institute for Ecology and Biological Resources and from the Forest Inventory and Planning Institute are now rapidly improving the quality of the available.

All of the restricted-range species are found in lowland rain forest, although the distribution of Rheinardia ocellata also extends upwards into montane forest and Garrulax vassali is principally a lower montane species of only marginal occurrence in this EBA. The three Lophura pheasants appear to be extreme lowland forest specialists, as they have not definitely been recorded above about 300 m. Jabouilleia danjoui occurs in lowland forest in this EBA, but is a montane forest bird in the Da Lat plateau (EBA 145). Stachyris herberti is a specialist of forest on limestone.

Several of the restricted-range species are known from just a few localities. The only recent records of Arborophila merlini are from Bach Ma National Park, where it is common. Lophura imperialis is known by one old record and a male trapped in 1990 near Cat Bin (Ke Go) on the border between Ha Tinh and Quang Binh provinces. L. edwardsi was historically known from at least eight localities in the southern part of the EBA, and was feared extinct in the wild (as it had not been recorded since about 1930) until a pair were captured near Bach Ma National Park in 1996 (Anon. 1996). L. hatinhensis occurs to the north of the range of L. edwardsi (and may be conspecific with it: Vuilleumier et al. 1992), with recent records near Cat Bin (Ke Go) (Ha Tinh province) in 1990 and in a nearby area of primary forest in the Net river watershed (Quang Binh province) in 1994. Stachyris herberti is known from specimens collected at two localities in central Laos in the 1920s and sightings in Phong Nha Nature Reserve in Bo Trach district in 1994 and Minh Hoa district in Quang Binh province in 1996 (J. C. Eames in litt. 1996). Jabouilleia danjoui and Macronous kelleyi have recently been recorded in Cuc Phuong National Park (Crosby 1995, J. C. Eames in litt. 1996), considerably further north than any previous record of any of the EBA’s restricted-range species:

V/ The South-East China Mountains EBA

The South-East Chinese Mountains EBA is home to five restricted range species, one of which, the White-eared Night-heron_Gorsachius magnificus, has been recorded in northern Vietnam in recent years.

VI/ Fansipan and Northern Laos

Four restricted-range species are recorded from the Fan-Si-Pan range in northern Vietnam: the threatened White-throated Wren Babler, Pale-throated Wren Babbler, Ward's Trogon Harpactes wardi, Red-winged Laughingthrush_Garrulax formosus, Broad-billed Warbler_Tickellia hodgsoni and the threatened Yellow-billed Nuthatch_Sitta solangiae. Broad-billed Warble has also been recorded in the mountains of northern Laos, and it is possible that some of these species also occur in the Ailao mountains in southern Yunnan province, China. They are found in broadleaf evergreen forest, scrub and bamboo above c.1,800 m, although Yellow-billed Nuthatch has been recorded down to 1,550 m on Fan-Si-Pan (Harrap and Quinn 1996). There has been extensive forest loss around Fan-Si-Pan and in the Ailao mountains. However, there are several protected areas in the Ailao mountains in China (IUCN 1992d), and Nui Hoang Lien Nature Reserve in Vietnam presumably includes montane habitats suitable for the restricted-range species:
White-throated Wren Babbler
Pale-throated Wren Babbler
Ward’s Trogon
Broad-billed Warbler
Red-winged Laughingthrush
Yellow-billed Nuthatch

Yok Don National Park is located in western Dak Lak Province bordering north-western Cambodia.

The park is bisected by the Srepok River, a major tributary of the Mekong River. Restricted-range species:
Mekong Wagtail
Giant Ibis
White-shouldered Ibis
White-winged Duck
White-rumped Pygmy Falcon
