HomeBa Be national park with nature lake
Saturday, May 24, 2014
Ba Be National Park lies in the Tropical Southern China area of the Indo-Malayan Realm. This region is characterised by steep limestone mountains, interspersed by lowland non-limestone areas. The underlying geology of the national park is limestone with topography being strongly separated and comprising many high mountain peaks, steep hill slopes, caves, valleys, streams and rivers. Ba Be Lake, which the national park is centred upon and after which it is named lies at 150m above sea level and the surrounding mountains rise up to 1,098m above sea level. The lake is mainly fed by the Ta Han, Cho Leng rivers and Bo Lu rivers.
Vegetation coverage mainly includes two types of forests: limestone and evergreen forests. Limestone forests are distributed on steep mountainsides where the soil is thin and cover most of the park area. Evergreen forests are distributed on low earthen hills covered with a thicker soil layer. The species diversity of the lowland evergreen forests is usually more diverse than those found on limestone mountains. The dominant limestone species include the threatened Burretiodendron hsienmu, Streblus tonkinensis among which climbing bamboo (Ampelocalamus sp) is endemic to the region and often found on hill slopes that lie adjacent to the lakeside.
The forests play an important role in watershed protection. Without this mosaic of plants, the land could likely be eroded due to intensive water flows and water restoration of the lake could therefore be weakened in the flood season. This would cause drought and flood every year, which threaten the lives of local communities in downstream of the Nang river.

Of the fauna in the national park, the most important mammal species for conservation are the Francois’ langur (Trachypithecus francoisi) and Owston’s Banded Civet (Hemigulus ownstoni). The Francois' Langur was first found in 1995 along the second bank of Ba Be Lake and, in 2001 rediscovered nearby along the Nang River.
The Vietnamese Salamander (Paramesotriton deloustali) was recently discovered in streams in the buffer zone of the national park. These were the first records for this endemic species outside of Tam Dao National Park and considerably extended its range.
The national park is also notable for its considerable butterfly diversity, for which to date over 300 species have been recorded.
Without doubt, the national park plays an important role in wetland biodiversity and habitats conservation, in particular for freshwater fish, including several species listed in the Red Data Book of Vietnam.
