Betung Kerihun National Park has eight types of forest ecosystems such as lowland forest, old secondary forest, Dipterocarpus, sub-montane and montane forest, with a high-value plant diversity of 1,216 species consisting of 418 genera and 110 families (75% endemic to Kalimantan). Fourteen species are “new records” in Indonesia, like Musa lawitiensis, Neouvaria acuminatissima, Castanopsis inermis, Lithocarpus philippinensis, Chisocheton cauliflorus, Syzygium spicata, and Shorea peltata; and 13 species of palm which are “new records” in Kalimantan, such as Pinanga bifidovariegata and Ixora sp.
Topographically, Betung Kerihun National Park is hilly. The Muller range which connects Mt Betung and Mount Kerihun also forms the border between Indonesia and Sarawak, Malaysia.
Small streams flow from the foothills of the Muller mountains to form the Kapuas, Sibau, Mendalam, Bungan, and Embaloh Watersheds. The Park can only be reached via these rivers.
There are some 48 species of mammal, including seven primate species such as the maroon leaf monkey (Presbytis rubicunda rubicunda), orangutan (Pongo satyrus), Mueller’s Bornean grey gibbon (Hylobates muelleri), white-fronted leaf monkey (Presbytis frontata frontata), and banded leaf monkey (P. femoralis chrysomelas); 301 species of bird, 51 species of amphibian, 52 species of reptile, 170 species of insect, and 112 species of fish.
The dominant and most commonly seen animals are orangutan (Pongo satyrus), sambar deer (Cervus unicolor brookei), western tarsier (Tarsius bancanus borneanus), Mueller’s Bornean grey gibbon (Hylobates muelleri), maroon leaf monkey (Presbytis rubicunda rubicunda), sun bear (Helarctos malayanus euryspilus), hairy-nosed otter (Lutra sumatrana), and larger Malay mouse deer (Tragulus napu borneanus).
The most distinct species of birds in this Park are the wreathed hornbill (Aceros undulatus) and the helmeted hornbill (Rhinoplax vigil) which is the mascot of West Kalimantan.
Betung Kerihun National Park has been proposed as a Trans-Border Reserve together with Lantjak Entimau Wildlife Reserve in Sarawak.
The potentially vast biodiversity riches of the Park pose a challenge to researchers to reveal them. But the Park also has several other attractions such as beautiful vistas over the forest crown which seems to go on forever; crystal-clear water flowing from waterfalls on the hilltops; birdcalls and the screeches and cries of various animals. As with other inland people throughout much of Kalimantan, most of the people living around the park are Dayak. Here, they belong to the Dayak Iban, Dayak Taman, and Dayak Bukat tribes. Many people are still adorned with tattoos in typical and very distinctive patterns.
