| The park was created to protect one of the world's two largest karst regions with 300 caves and grottoes and also protects the ecosystem of limestone forest of the Annamite Range region in North Central Coast of Vietnam. | WIKI |
| [5] The plateau on which the park rests is one of the finest and most distinctive examples of a complex karst landform in Southeast Asia. | WIKI |
| The park is bordered by the Hin Namno karst area of Khammouane Province of Laos in the west. | WIKI |
| The Phong Nhaxe2x80x93Kxe1xbaxbb Bxc3xa0ng karst has evolved since the Paleozoic (some 400 million years ago), making it the oldest major karst area in Asia. | WIKI |
| 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. | WIKI |
| This makes Phong Nha the oldest major karst in Asia. | WIKI |
| If the Hin Namno, bordering Phong Nha on the west (in Laotian territory) was to be combined with the national park in a continuous reserve, the combined reserve would be the largest surviving karst forest in southeastern Asia (317,754 ha). | WIKI |
| Karstic landforms in this area are of typical tropical karst which are divided into two groups of forms: The karstic forms on the surface including cone and tower karst, karrens, valleys and dolines, border polje, etc. | WIKI |
| ; The underground karst consisting of caves. | WIKI |
| In comparison with three other national parks listed in UNESCO's World Heritage Sites in Southeast Asia, namely Gunung Mulu National Park in Malaysia, Puerto Princesa Subterranean River National Park in Palawan of the Philippines and Lorentz National Park in West Irian of Indonesia and some other karst regions in Thailand, China, Papua New Guinea, karst in Phong Nha-Kxe1xbaxbb Bxc3xa0ng is older, has more complicated geological structure; diverse and complex underground rivers. | WIKI |
| [4] According to the assessment of UNESCO, "The karst formation of Phong Nha-Kxe1xbaxbb Bxc3xa0ng 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. | WIKI |
| This bureau stated that the site was part of an extremely complex and ancient karst plateau with high geodiversity which also encompasses Kxe1xbaxbb Bxc3xa0ng and Hin Namno karsts. | WIKI |
| The property contains and protects over 104xc2xa0km of caves and underground rivers making it one of the most outstanding limestone karst ecosystems in the world. | UNESCO |
| The karst formation has evolved since the Palaeozoic period (some 400xc2xa0million years ago) and as such is the oldest major karst area in Asia. | UNESCO |
| Subject to massive tectonic changes, the karst landscape is extremely complex, comprising a series of rock types that are interbedded in complex ways and with many geomorphic features. | UNESCO |
| The karst landscape is not only complex but also ancient, with high geodiversity and geomorphic features of considerable significance. | UNESCO |
| The karst formation process has led to the creation of not only underground rivers but also a variety of cave types including: dry caves, terraced caves, suspended caves, dendritic caves and intersecting caves. | UNESCO |
| There is evidence of at least one period of hydrothermal activity in the evolution of this ancient mature karst system. | UNESCO |
| The plateau is one of the finest and most distinctive examples of a complex karst landform in Southeast Asia and the property is of great importance for enhancing our understanding of the geologic, geomorphic and geo-chronological history of the region. | UNESCO |
| The property includes karst formations which are some of the oldest and largest in Asia, and it has geological, climatic, hydrographic and ecological conditions which are distinct from other limestone karst landscapes. | UNESCO |
| The property constitutes one of the largest remaining areas of relatively intact moist forest on karst in Indochina, with a forest cover estimated to reach 94%, of which 84% is thought to be primary forest. | UNESCO |
| Importantly, four threatened primate taxa endemic to the Annamites are found within the property: the Hatinh Langur (specialised in karst forest and endemic to Viet Nam and the Peoplexe2x80x99s Democratic Republic of Lao), the black form of the Hatinh Langur, sometimes considered as a separate species, the Red-shanked Douc Langur, and the largest remaining population of White-cheeked Gibbon. | UNESCO |
| The property constitutes one of the largest protected karst landscapes in South East Asia. | UNESCO |
| Furthermore, the extension of the property enhances its integrity and connectivity with the karst landscape in Lao PDR. | UNESCO |
| It is paramount that such developments do not impact on the karst and biological values for which the property has been inscribed. | UNESCO |
