Boundaries

In the southwest of Dong Phou Vieng NBCA the western boundary runs along aroad leading from Ban Khe-Tai to Ban Bok. It continues along the Xe Kamouak until the mouth of Houay Ketxan.

The northern boundary runs along the Houay Ketxan and the Xe Chon till Ban Kammakon. Here it turns south still going up the Xe Chon and then crossing the mountains till it reaches the Xe Banghiang. It goes up the Xe Banghiang and then proceeds first along the mountain slopes and then along the Xe Pon till Ban Dong.

The eastern boundary follows the road No. 4 from Ban Dong south to Ban Theum and then the trails leading east till it reaches Houay Patou near Ban Lapit. It follows Houay Patou till it enters the Xe Lanong. Then the boundary runs along the Xe Lanong till it meets again with the Road No. 4 near Ban Along-Nam. It follows the road No. 4 south till it reaches the provincial boundary between Savannakhet and Salavan provinces. Here the boundary turns east.

The southern boundary of Dong Phou Vieng NBCA is formed by the provincial boundary west of road No. 4 and by the rivers Xe Tanouan and Xe Banghiang till it reaches Ban Khe-Tai.

Access

The main access is by road No. 9, which runs close to the northern boundary. Starting from this road in Muang Phin, road No. 23 leads through the western part
of Dong Phou Vieng NBCA and passes the southwestern NBCA boundary near Ban Tat-Hai. From this road another one leads to Kaeng Samatae.

In Ban Dong in the east starts road No. 4 running south. In some stretches it forms the NBCA boundary. Parting from this road, several trails lead to the villages inside the NBCA. Some paths even cross the NBCA.

Besides by road, Dong Phou Vieng NBCA is accessible also by boat, as the Xe Banghiang crosses the NBCA.

Stakeholder
Villages and
Population

Due to lack of information and the fact that the Land and Forest Allocation has not yet been implemented in most of the area, it is only possible to distinguish two types of villages:
Villages situated inside Dong Phou Vieng NBCA
II. Villages situated in the surroundings of Dong Phou Vieng NBCA

The population data were collected by the State Planning Committee of the National Statistical Centre for the National Population Census 1995.

For Xepon District the population data are not complete. The NBCA staff listed village names, which could not be found in the lists of the National Population Census of 1995.

2. BRIEF HISTORY

Management History:
Since October 1996, the Forest Management and Conservation Programme (FOMACOP), a joint undertaking of the Government of Lao PDR (GoL), the International Development Association (IDA) of the World Bank, the Global Environmental Facility, and the Government of Finland through FINNIDA, has been assisting the Lao government in the Management of Dong Phou Vieng NBCA.

3. ECOLOGY

Physical
Features

• Major mountains:
  Phou Lapeung – Nua (1122 m above sea level)
  Phou Dotouy (1254 m above sea level)

• Extended river banks of Xe Banghiang and Xe Lanong

• Rapids

Elevation

200 m - 600 m asl. with peaks up to 1254 m asl.

Climate

Dong Phou Vieng lays in the Southeast Asia monsoon climate. During the winter (November – February), when the sun is to the south of the equator the climate is under the influence of the cold continental high pressure region over China. The winds are clockwise around the high and come from the northeast over Southeast Asia. This is the Northeast Monsoon, characterized by cold dry air and infrequent light rain.

For the summer (May – August), the sun is to the north of the equator and heats the land mass beneath to a degree that causes an extensive low pressure region called Intertropical Convergence Zone and the Monsoon Trough. Warm winds from the southwest carry moisture from the Andaman Sea and the Gulf of Thailand to the part of the trough in the Lao PDR region where vertical convection causes rainfall, large amounts during the height of the monsoon season. This is the Southwest Monsoon. The air is warm and humidity high.

Main Forest
Types

• Deciduous Dipterocarp Forest

• Semi – evergreen Forest

• Mixed Deciduous Forest

Forest Cover
This calculation was realized by the Forest Cover Monitoring Project (FCMP) MRC / GTZ. It is based on interpretation of 1996/97 Landsat TM with the NBCA boundaries as shown on topographical maps 1:100 000 provided by the FOMACOP project. Verification with the original documents has not taken place. Therefore the data might be only approximate.
