Park layout

Before becoming a national park, this area had been a nature reserve. The Phong Nha Nature Reserve with an area of 50 km2 was officially declared by the Vietnamese government on 9 August 1986 and was extended to 411.32 km2 by 1991. On December 12, 2001, the Vietnamese Prime Minister by Decision 189/2001 189/2001/QĐ-TTG turning then a nature reserve into a national park. The purpose of this protected area is to protect forest resources, biodiversity within the boundary of this national park and to preserve scientific values of fauna and flora in Bắc Trung Bộ

 area in Asia. It has been subject to massive tectonic changes, and comprises a series of rock types that are interbedded in complex ways. Probably as many as seven different major levels of karst development have occurred as a result of tectonic uplift and changing sea levels, thus the karst landscape of PNKB is extremely complex with high geodiversity and many geomorphic features of considerable significance. Like much of Vietnam, it has been subject to extensive tectonic change, and so the limestones of Phong Nha are inter-bedded with a number of other rocks. There is also strong evidence that sulphurous solution and hydrothermal action have played an important role in shaping the broad-scale landscape and the caves, though this has not yet been properly assessed.

Phong Nha-Ke Bang area today is a result of 5 stages of Earth's crust development and movement in this area:
  • Late Ordovician - Early Silurian Stage (about 450 Ma)
  • Middle-late Devonian Stage (about 340 Ma)
  • Carboniferous-Permian (about 300 Ma)
  • Mesozoic Orogenic stage
  • Cenozoic stage.

, The karst formation of Phong Nha-Ke Bang National Park has evolved since the Palaeozoic (some 400 million years ago) and so is the oldest major karst area in Asia and Phong Nha displays an impressive amount of evidence of earth's history. It is a site of very great importance for increasing our understanding of the geologic, geomorphic and geo-chronological history of the region.

Etymology

The name Phong Nha-Ke Bang includes Phong Nha cave and Ke Bang limestone forest. Phong Nha is widely explained as originating from Hán tự: 风牙, which means wind-tooth (wind flowing from the cave and stalactite
Stalactite

s inside the cave looking like teeth), but other theorires suggest that Phong Nha is the name of a nearby village and therefore, its name has nothing to do with wind and teeth as widely explained

According to Lê Quý Đôn, Phong Nha was the former name of a nearby village.
Other theory suggests that, Phong Nha derived its name from the imagination that mounts in this region standing in line looks similar to the scene of mandarins in front of the king in royal courts, therefore, it was named Phong Nha (Han Tu: phong (峰) means "summit" and nha (衙) means "mandarin").

Other names of Phong Nha cave includes: Thầy Tiên cave, Thầy Mount, and Troóc cave.

The Phong Nha cave

This cave from which the name to the whole system and the park is derived is famous for its rock formations which have been given names such as the "Lion", the "Fairy Caves", the "Royal Court", and the "Buddha

". This cave is 7729 m long, contains 14 grottos, with a 13,969 m-long underground river. The scientists have surveyed 44.5 km of grottos in this cave so far, but tourists can only penetrate to a distance of 1500 m. Phong Nha Caves, like most of the caves in this area, has been continuously shaped by the Chay River. As one gets farther into the cave, the more illusory the stalactites and stalagmites look as they glitter when bright light is shone on them. The Son River flows into the mouth of the cave and keeps flowing underground, where it is referred to as the Nam Aki River, then this river emerges at a site 20 km to the south near Pu Pha Dam Mountain. The main Phong Nha cave includes 14 chambers, connected by an underwater river that runs for 1.5 km. Secondary corridors branch off in all directions. The Outer Cave and some of the Inner Caves have roofs that tower between 25 and 40 meters above the water level. From the 14th chamber there may be other corridors leading to similarly large chambers, but this area proves more dangerous for explorers because of the ongoing erosion of the limestone of the cavern. The Shallow cave is located 800 meters from the cave mouth, where there is a spectacular landscape of sand and rock. Stalactites and stalagmites jut out like strange trees, exciting visitor's imaginations. Notable caves and grottos:
Phong Nha Cave system:
  • Dark Grotto (Hang Tối): located upstream of Son River running to the branch of Chay River on the left. This cave is 5,258 m long and with a height of 83 m. The entry is high and wide with heavy forest around the cave mouth.

  • E Grotto (Hang E): a 736 m-long grotto accessible by Ho Chi Minh Trail

  • Cha An Grotto (Hang Chà An): a 667 m-long grotto, with the width of 15 m.
  • Thung Grotto (Hang Thung): This grotto has an underground river of 3351 m, with the height in some part exceed 133 . This river receives water resources from Rao Thuong.
  • En Grotto (Hang Én): a 1645 m long, 78.6 m high grotto. The grotto is wide, there is fine sand field inside. This grotto is the habitat of thousands of sparrows.
  • Khe Tien Grotto (Hang Khe Tiên): located south of Phong Nha, this grotto is 520 m long.
  • Khe Ry Grotto (Hang Khe Ry): located south of Phong Nha. The grotto is where the stream Khe Ry (a 13.817 km or 8.585 mi (13.8 km) long stream at the elevation of 120 m, originating from a mount 1300 m high) runs out.
  • Khe Thi Grotto (Hang Khe Thi): The Khe Thi stream originating from the mount and runs underground at this grotto.

Vom Cave systems

  • Vom Grotto (Hang Vòm): a 15.05 km long, 145 m high grotto with several underground rivers, pools. This grotto features several spectacular stalagmite and stalactites. In the recent exploring of British Cave Research Association, the scientists have found an abyss in Vom Grotto named Tang hole with the deep of over 255m. This hole is the deepest hole in Vietnam.
  • Dai Cao Grotto (Hang Đai Cao): this grotto is a connection of Vom Grotto. This grotto is 1645 m long, 28 m high..
  • Duot Grotto (Hang Duột): This is a connection of Dai Cao Grotto with the length of 3.927 km and height of 45 m. There are some fine sand fields inside.
  • Ca Grotto (Hang Cá): a 1,500 m long, 62 m high grotto.

  • Ruc Caroong Grotto (Hang Rục Caroòng): This the habitat of Arem ethnic group. They live in the caves, grottos and on hunting, harvesting natural products.

Tien Son Cave

Tien Son cave is another beautiful cave in Phong Nha-Ke Bang area. Tien Son cave was discovered by a local inhabitant by accident in 1935. It is located in Son Trach Commune, Bố Trạch District. The entry mouth of Tien Son is 1 km from Phong Nha cave, at an altutude of 200 m. This cave is 980 m in length. A 10 m deep hole is situated 400 m from the entry mouth, then a 500 m long underground cave, dangerous for tourists and therefore is open to professional expeditionists only. Like Phong Nha cave, this cave features spectacular stalactites and stalagmites shaped like several fairy-tales. Stalactite and stalagmite columns and walls here create strange sounds like that of gong and drum if they are knocked with the hand. According to British cave scientists, Tien Son cave was created tens of million years ago when a water current holed this limestone mount in Ke Bang. Following a series of landforms and movement of rocks, this mass was levered or lowered, blocking the current and creating what is now Tien Son cave while the underground river redirected its current to Phong Nha cave. Although Phong Nha and Tien Son caves are located next to each other, there are no linking grottos between them.

From the end of March to April 14, 2009, he helped the explorers to traverse the 10 kilometer forest pass to access the cave mouth. Because of the difficulty in traversing into the cave as well as dangerous conditions in the cave, the cave will be open only to scientists in the near future.
The cave was found by a local man named Hồ-Khanh in 1991. The local jungle men were afraid of the cave for the whistling sound it makes from the underground river. However, not until 2009 was it made known to the public when a group of British scientists from the British Cave Research Association

Nomination and recognition in 2003

Phong Nha-Ke Bang National Park was first nominated as a UNESCO World Heritage Site in 1998. Dossiers was first submitted by Vietnamese government to UNESCO for recognition of Phong Nha nature reserve as a world natural heritage under the name "Phong Nha Nature Reserve". The reason given for the nomination was that this nature reserve satisfied criteria of biodiversity, unique beauty and geodiversity (criteria I and iv).

In 1999, the World Conservation Union

 (IUCN) conducted a field survey in January and February. At the meeting in July 1999, Evaluation Bureau concluded that Phong Nha Nature Reserve would meet with criteria I and IV as a world heritage nominee on the condition that this nature reserve was expanded to include the larger Phong Nha Ke Bang National Park with an associated fully integrated management structure. This bureau stated that the site was part of an extremely complex and ancient karst plateau with high geodiversity which also encompasses Ke Bang and Hin Namno karsts. The reserve is largely covered in tropical forest with a high level of biodiversity and endemic species. Lack of research means that the true significance of the biodiversity and geology of the area cannot be fully assessed. The evaluation bureau concluded that the nominated area on its own is not considered to meet World Heritage criteria. Nevertheless, if this nature reserve was jointly nominated with the Hin Namno karst ecosystem in Laos

, the combined site would constitute the largest surviving area of karst forest in South-east Asia and may merit World Heritage status. The Bureau decided to defer the nomination of Phong Nha Nature Reserve.

In 2000, the government of Vietnam submitted a revised nomination with a much larger area. At this time, however, the National Assembly and government of Vietnam also announced that it would be constructing the north-south Ho Chi Minh Highway and a link road between the Highway and Route 20 that bisects part of the core area of the Phong Nha Nature Reserve. The news of this road construction raised concern over its impacts on the Phong Nha Nature Reserve, and many international organization like IUCN, Flora and Fauna International called on Vietnamese government to reconsider its plan. They also advised of the negative impact of these road and construction activities on biodiversity. Due to this plan of road construction, the evaluation bureau did not proceed further consideration of nomination from Vietnamese government at that time.

The government of Vietnam provided the bureau with additional information in May 2002, announcing the decision of the Prime Minister of Vietnam

 (December, 2001) on the upgrading of the Phong Nha – Ke Bang Nature Reserve to the Phong Nha – Ke Bang National Park with a total area of 857.54 km2; providing information on projects for the conservation and development of the Park and revised maps. This revised nominated site has a much smaller area than the 2000 nomination, though still relatively larger than that of 1998.

It was recognized as a world natural heritage site at the UNESCO's 27th general assembly session being held in Paris June 30–July 5, 2003. At the session, delegates from over 160 member countries of UNESCO World Heritage Convention agreed to include Phong Nha-Ke Bang park and 30 others worldwide in the list of world heritage sites. Phong Nha-Ke Bang National Park meets with criteria viii in accordance with UNESCO's appraisal scale as it displays an impressive amount of evidence of earth's history and is a site of very great importance for increasing human understanding of the geologic, geomorphic and geo-chronological history of the region.

Recognition for a second time

The National Council for Cultural Heritage, an organization under the Ministry of Culture and Information of Vietnam (now the Ministry of Culture, Sports and Tourism) recommended the Vietnamese prime minister that Phong Nha-Ke Bang National Park be submitted to UNESCO second time for recognition as a world natural heritage for biodiversity (in 2003, this park was listed in UNESCO's world heritage sites for criteria viii "outstanding geological, geomorphical, and geographical values".

Vietnamese and international experts believed that if Vietnam timely submits the proposal documents to UNESCO and meet this UNESCO's criteria, this national park will be recognized for a second time in 2008.

Since the recognition by UNESCO in 2003, the government of Vietnam has continued to compile scientific documentation to seek recognition of the park as a world natural heritage in terms of biodiversity in addition to geographical values. According to World Wildlife Foundation report in 2000, Phong Nha-Ke Bang National Park is one of 200 biodiversity centres of the world and one of the 60 significant sanctuaries of Vietnam. It has a unique forest type in the world: green tropical forest. The park also has 15 other types of forests.

At the final conference of the National Council for Cultural Heritage held in Vietnam in 2007, scientists attending the meeting highly praised the scientific documentation of Phong Nha-Ke Bang park. Accordingly, the park is second to no other national parks listed in UNESCO's world heritage sites as far as biodiversity is concerned.

Tourist activities in Phong Nha-Ke Bang National Park are organized by local travel agencies and vary in form:
  • Tour for expedition of caves and grottos in boats and with professional cave expedition means.
  • Ecotourism, discovering the flora and fauna in this national park in the Ke Bang Forest.

  • Mountain climbing, trekking: There are extreme sloping mountains here with a height of over 1,000 m, which is a real challenge for adventurous climbers.


One of the adventure tour sites is boating upward on the Chay River into primitive forests, as the river becomes sinuous with several waterfalls and whirlpools until tourists arrive at Tro Mong. This tour sites have been surveyed and included in local travel agents besides cave exploration tour. In Phong Nha-Ke Bang park, there are is a 50 m-high waterfall, Chai Waterfall. There is a bull field called Ran Bo (Bull Field) because wild bulls usually comes and reproduce in mating season. There are also some interesting tourist attractions in this park like Nước Ngang (lit.: Horizontal Spring), a spring runs horizontally instead of vertically as usual; Ðá Nằm (Crouching Stone), a stone blockading a stream current; Chân Thớt (Chopping Board), a chopping-board-shaped stone. But above all, the most spectacular scene is this area is Nước Trồi (Surfacing Stream), a stream surfacing from the ground. Several streams here run for a long distance, then disappear under the ground.

Thanks to the tourism development in this national park, about 1000 local residents have jobs in tourism. The provincial Centre for Phong Nha-Ke Bang's Ecotourism and Culture currently has 248 boats, creating jobs for 500 locals. Every boat has two trained boatmen earning VND70,000 per day. This income is relatively high for peasants in this province. This centre also launched a programme in 2000 to train former loggers to work as photographers taking pictures for tourists and about 300 former loggers are now doing this.

Management activities

The Park Management Board includes just 115 people, composed of zoologists, botanists, silviculturalists, and socio-economists. This management staff lacks the authority to fine violators and lacks equipment like helicopters and sufficient funds, thus it's hard to efficiently deal with natural and human threats to the park.

A semi-wild zone of 0.18 km2, surrounded by electrical wire fence, saved for the primate species was created in this park. This project is sponsored by Zoologische Gesellschaft Frankfurt (Germany) in order to provide a sanctuary for 10 species of primates, including Trachypithecus francoisi hatinhensis, Red-shanked Douc langur or Pygathrix nemaeus nemaeus. This protection zone is suitable for primates habitat.

Threats to biodiversity

There are two villages of Arem an Ma Coong ethnic groups in the core zone of the Phong Nha-Ke Bang National Park. Within the buffer zone, there is a population of 52,001. They are mainly Kinh people and other minority groups of Chut and Van Kieu, many of them exploit forest products as part of their livelihoods.

The increase of visitors to this park is also a problem to the park since unexpected pollution (water pollution, rubbish), human impacts on caves and grottos may cause damage to them and especially threaten biodiversity. Hunting is a significant threat to the wildlife because local people have a great consumption demand on wild meat and this has contributed to the significant decrease of species such as the wild pig, binturong

Land management in adjacent areas

The land management and regulation of the commercial activities in the area surrounding the park have been carried out by the provincial authorities in a disorganized manner. Blocks of land have been sold to local investors and inhabitants for building service utilities in a haphazard way, resulting in the formation of a slum at the entrance of the park. This has been compounded by some investors who do not develop their lots but hold them for future sale. The planning scheme for 2 km2 of land adjacent to the park was criticized by many experts as having been done "without future vision". Quang Binh's provincial government responded by declaring their intention to recruit internationally-recognised planners to help draft tourism development plans for the adjacent areas.

International funding

On November 3, 2005, the German government announced funding valued at 12.6 million euros for the park's management board for the purpose of protecting the biodiversity of the park.

In 2007, the German government donated a further 1.8 million euros to Vietnam for protection of this park.

Fauna & Flora International donated USD 132,000 to Phong Nha-Ke Bang National Park Management Board for the protection of primates in this national park as well as in the buffer zone.

In 1998, FFI conducted a training project for the management staff of the park. The British Commission for International Development sponsored a fund for the WWF
