Dakrong Criteria: A1, A2 & A3

Province(s): Quang Tri

PA Status: None
Latitude: 16º31'N

Longitude: 107º01'E

Area: 40,526 ha

Altitude Range: 300-1,102 m asl

EBA / SA:

Annamese Lowlands EBA

Priority Landscape:

CA 1 - Central Annamites

General Description

The IBA is situated in the Annamese lowlands and comprises Dakrong proposed nature reserve. The topography of the IBA is characterised by hills and low mountains. Prior to the Second Indochina War, the IBA supported extensive areas of lowland evergreen forest and lower montane evergreen forest. However, wartime spraying of defoliants, the practice of shifting cultivation by local communities, and a long history of over-exploitation of natural resources have resulted in the forest becoming heavily degraded and fragmented. Currently, primary forest only covers around 60% of the IBA. However, most fragments of primary forest are relatively large and contiguous with areas of mature secondary forest¹. To the east, Dakrong IBA is contiguous with Phong Dien IBA in Thua Thien Hue province.

Bird Fauna: Key Features

Dakrong IBA supports five of the nine restricted-range species found in the Annamese Lowlands Endemic Bird Area (EBA). Most significantly, Dakrong IBA, together with the neighbouring Phong Dien IBA, supports what is possibly the largest remaining population of the globally endangered Edwards's Pheasant Lophura edwardsi in the world. In 2000, Imperial Pheasant L. imperialis, another pheasant species endemic to central Vietnam, was recorded at Dakrong IBA. However, recent taxonomic research indicates that Imperial Pheasant may not be a true species but, rather, a hybrid between Edwards's Pheasant or Vietnamese Pheasant L. hatinhensis and Silver Pheasant L. nycthemera².

Species	IBA Criteria	Global Threat Status	Other IBAs	Notes
Edwards's Pheasant Lophura edwardsi	A1, A2	EN	2	A pair were trapped by local people in December 1996. Four birds were trapped by local hunters between 50 and 300 m asl in December 1997. Two individuals were caught by local hunters, who also reported seeing a flock of 8 to 10, between the end of 1997 and the beginning of 1998¹.
Crested Argus Rheinardia ocellata	A1, A2	VU	15	The species was recorded between June and July 1998¹.
Siamese Fireback Lophura diardi	A1, A3	NT	13	The species was recorded between June and July 1998¹.
[Brown Hornbill Anorrhinus tickelli]	A1, A3	NT	17	The species was provisionally recorded between June and July 1998¹.
Blyth's Kingfisher Alcedo Hercules	A1, A3	NT	8	The species was recorded between June and July 1998¹.
Short-tailed Scimitar Babbler Jabouilleia danjoui	A1, A2	NT	17	The species was recorded between June and July 1998¹.
Imperial Pheasant Lophura imperialis	A1, A2	DD	2	A juvenile male was caught in the watershed of the Long An stream, near Mount Dong Che in February 2000³.
Annam Partridge Arborophila merlini	A2		4	The species was recorded between June and July 1998¹.

Notes: [ ] = unconfirmed record.

Biome Restricted Species: The site qualifies under criterion A3 because it supports 14 species restricted to the Indochinese Tropical Moist Forests (Biome 09). See Appendix 4 for details.

Threats to Biodiversity

Threat	Severity
Agricultural intensification / expansion	●
Forest grazing	●
Hunting	● ● ●
Selective logging / cutting	● ●
Unsustainable exploitation of NTFPs	●

One of the biggest threats to biodiversity at Dakrong IBA is hunting, particularly the use of snares. Snaring is an indiscriminate activity with potentially severe impacts on ground-dwelling birds, such as Edwards's Pheasant, Crested Argus Rheinardia ocellata and Annam Partridge Arborophila merlini. Recent research conducted at Phong Dien IBA revealed that snaring is often associated with rattan collection⁴. Other threats to biodiversity at the IBA include small-scale timber extraction, clearance of forest for agriculture, mining and livestock grazing.

Conservation Actions

An investment plan for Dakrong was prepared in 2000, which proposed establishing a 40,526 ha nature reserve at the site. This investment plan was approved by Quang Tri Provincial People's Committee in 2000 and by the Ministry of Agriculture and Rural Development in 2001⁵. To date, however, the establishment of a nature reserve at Dakrong has not been decreed by the government of Vietnam.

Recommendations

Dakrong should be decreed as a nature reserve, a management board should be established, and protected area management regulations should be enforced, particularly controls on hunting.

Local communities should be involved in forest protection and management.
Environmental awareness activities should be implemented among local communities.
Further studies should be conducted to assess the habitat requirements of Edwards's Pheasant.
