Bukit Barisan Selatan National Park (BBSNP) or the South Bukit Barisan National Park - spans over three of Sumatras provinces. They are: Lampung, South Sumatra and Bengkulu. Along with Mount Leuser and Kerinci Seblat, the combined national parks make up the Tropical Rainforest Heritage of Sumatra inscribed in the UNESCOs World Heritage List, which runs along the entire western spine of the island. The main objective of the national park is to protect the existence of Sumatras tropical rainforests along with all their biodiversity. Sumatran Elephants (Elephas maximus sumatranus), Sumatran tigers (Panthera tigris sumatrae) and Sumatran Rhinoceros (Dicerorhinus sumatrensis) are among some of the rare and exotic fauna found in the area.
Starting as a Wildlife Sanctuary in 1935, the area became a National Park in 1982. Initially, South Bukit Barisan Park covered a total area of 356,800 hectares, but recent measurements using GIS recorded that the latest total area is in fact 324,000 hectares. The park is located at the southwestly end of Sumatra. Seventy percent of the park lies within the administrative areas of West Lampung and Tanggamus in the Lampung Province, while 74,822 hectares (about 23%) is located within the boundaries of Kaur district, in the province of Bengkulu. While the remainder of the park lies within the province of South Sumatra.
The South Bukit Barisan Park is included in the Global 200 Ecoregions, WWF's ranking of the Earth's most biologically outstanding terrestrial, freshwater and marine habitats. The park is also highlighted as a priority area for the Sumatran rhino conservation through WWF's Asian Rhino and Elephant Action Strategy (AREAS). In addition, IUCN, WCS and WWF have identified the South Bukit Barisan as "Tiger Conservation Unit I", the most important forest area for the conservation of tigers in the world. Other endemic fauna that also inhabit the area are: honey bears (Helarctos malayanus malayanus), tapirs (Tapirus indicus), ungko (Hylobates agilis), siamang (H. syndactylus syndactylus), simpai (Presbytis melalophos fuscamurina), kancil (Tragulus javanicus kanchil), and the scaled sea turtles (Eretmochelys imbricata).
Aside from its fauna, the park also presents splendors in leaves and flowers. The exotic Giant Carrion Flowers or Titan Arum (Amorphophallus titanium) and the Tall Carrion Flowers (Amorphophallus decus-silvae) are among the largest flowers existing on earth. The height of the Amorphophallus decus-silvae has been recorded to reach over 2 meters tall. Generally confused with the Carrion Flowers, the Rafflesia flowers (Rafflesia arnoldii) are also found in certain areas of the park. The Rafflesia flower is noted for producing the largest individual flower on earth, while the Titan Arum and Talipolt Palm are technically clusters of many flowers. The national park is also home of the largest orchid known to the planet, locally popular as Anggrek Tebu or Sugarcane Orchid (Grammatophyllum speciosum).
Other flora in this South Bukit Barisan Park include: pidada (Sonneratia sp.), nipah (Nypa fruticans), Sea Pines (Casuarina equisetifolia), pandan (Pandanus sp.), cempaka (Michelia champaka), meranti (Shorea sp.), mersawa (Anisoptera curtisii), ramin (Gonystylus bancanus), keruing (Dipterocarpus sp.), damar (Agathis sp.), and rattan (Calamus sp.)
