context_page_description: Quảng Bình, formerly Tiên Bình under the reign of Lê Trung Hưng of the Lê dynasty, is a province along Vietnam's north-central coast.
  The province has an area of 8,065.8 square kilometers and population of 857,818 inhabitants The province is bordered by the Laotian Khammouane Province to the west, the North Pacific Ocean to the east, Hà Tĩnh Province to the north and Quảng Trị Province to the south. Historically, this region belonged to Văn Lang and later the kingdom of Champa. Later it was claimed by both the Đại Việt and Champa and officially annexed into Đại Việt by Lý Thường Kiệt, a Lý dynasty general.
  The site of present-day Quảng Bình was battlefields between Champa and Vietnam until the Vietnamese territory was expanded further south by subsequent dynasties. Quảng Bình's importance expanded after Nguyễn Hoàng, a prince of Nguyễn lords was sent to the south by a king of the Lê dynasty. Hoàng built his estate and turned it into Đàng Trong, a rival of the de facto Trịnh-controlled Đàng Ngoài. Quảng Bình became an important front to defend Đàng Trong from attack by Đàng Ngoài. Under French rule, this province was part of Annam.
context_section_description: Quảng Bình Province is endowed with biodiversity, especially typical of Annamites eco-region. According to the results of initial surveys, the primary tropical forest in Phong Nha-Kẻ Bàng is home to 140 families, 427 genera, and 751 species of vascular plants, of which 36 species are considered endangered and listed in the Vietnam's Red Data Book. The most common tree species in this park are Hopea sp., Sumbaviopsis albicans, Garcinia fagraeoides, Burretiodendron hsienmu, Chukrasia tabularis, Photinia arboreum and Diospyros salletii. Seedlings can only grow in holes and cracks in the limestone where soil has accumulated, so in general regeneration after disturbance is slow. The forest type in this national park is dominated by evergreen tree species with scattered deciduous trees such as Dipterocarpus kerri, Anogeissus acuminata, Pometia pinnata and Lagerstroemia calyculata. In Phong Nha-Kẻ Bàng, the dominant plant families are the Lauraceae, Fabaceae, Theaceae and Rosaceae, with some scattered gymnosperms such as Podocarpus imbricatus, Podocarpus neriifolius, and Nageia fleuryi.
  In the national park there is a 5000-ha forest of Calocedrus macrolepis on limestone (Calocedrus rupestris) mounts with about 2,500 trees, 600 per hectare. This is the largest forest of this tree in Vietnam. Most of these trees here are 500–600 years old. These trees are listed in group 2A (rare, precious and limited exploitation) of the official letter 3399/VPCP-NN dated 21 June 2002, an amendment to Decree 48 by the Government of Vietnam. Biologists discovered three rare orchid species. Orchids found here include: Paphiopedilum malipoense, Paphiopedilum dianthum, Paphiopedilum concolor. In 1996, IUCN classified these orchid species in danger of extinction in the near future.
  Endemic species in Phong Nha-Kẻ Bàng National Park include: Burretiodendron hsienmu, Cryptocarya lenticellata, Deutzianthus tonkinensis, Eberhardtia tonkinensis, Heritiera macrophylla, Hopea sp., Illicium parviflorum, Litsea baviensis, Madhuca pasquieri, Michelia foveolata, Peltophorum tonkinensis, Semecarpus annamensis, Sindora tonkinensis.
