Bukit Duabelas National Park is representative of lowland tropical rain forests in the province of Jambi. In the past, the forest area functioned as a permanent production forest, limited production forest and other forest land uses which were later merged to become the National Park. The remaining natural forest is situated in the northern part of the park, while the rest comprises secondary forest.
Plant species in the Park include bulian (Eusideroxylon zwageri), meranti (Shorea sp.), menggiris/kempas (Koompassia excelsa), jelutung (Dyera costulata), damar (Agathis sp.), jernang (Daemonorops draco), and rattan (Calamus sp.). There are about 120 species of plant, including fungi, which could be developed as medicinal plants.
This Park forms a habitat for endangered and protected animals like siamang (Hylobates syndactylus syndactylus), clouded leopard (Neofelis nebulosa diardi), lesser Malay mouse deer (Tragulus javanicus kanchil), sun bear (Helarctos malayanus malayanus), barking deer (Muntiacus muntjak montanus), leopard cat (Prionailurus bengalensis sumatrana), hairy-nosed otter (Lutra sumatrana), Asian wild dog (Cuon alpinus sumatrensis), Sumatran rabbit (Nesolagus netscheri), crested serpent eagle (Spilornis cheela malayensis), etc.
Owing to the existence of so many rivers and tributaries (appearing on the map like root fibres) which drain from within the Park area, Bukit Duabelas National Park is an important water catchment area for the Batanghari watershed.
The topography of the Park varies from flat to slightly hilly with a few higher hills like Suban, Punai (” 164 m asl.), Panggang (” 328 m asl.), and Kuran (” 438 m asl.).
The indigenous people of the Anak Dalam tribe (Orang Rimba) have been dwelling in the forest area of the Park for many years. They use the forest as a place to roam where they can interact with the nature, maintaining a symbiotic relationship with the forest. To meet their daily needs, the indigenous people hunt pigs, fish, collect honey, and tap the sap from rubber trees for sale.
As for modern conveniences, most of the Anak Dalam use only wristwatches and battery-operated radios. Other than that, their simple way of life remains more or less intact. At night, they use resin torches as a source of light. The Anak Dalam community needs to be empowered so that they can benefit from improved knowledge and welfare, but this should not be at the cost of contaminating their culture.
The Bukit Duabelas area has only recently been declared by the Minister of Forestry and Estate Crops as a National Park, and as such has relatively few facilities for visitors.
