Betung Kerihun National-Park Introduction

Betung Kerihun National-Park Introduction

Bentuang Karimun National Park is located at the headwaters of the Kapuas River in the far interior of West Kalimantan. The site covers an area of 800,000 ha. and borders the 200,000 ha. Lanjak Entimau Wildlife Sanctuary in Sarawak. Together, these two parks form one of the first transborder parks in SE Asia.
The topography of the area ranges from lowland elevations at about 200 m to mountains almost 2,000 m high. As such, the site serves as an important water catchment area. Three of Borneo’s greatest rivers, the Rejang and Lupar River in Sarawak and the Kapuas River in Kalimantan have their origins here. Habitats comprise lowland Dipterocarp forest, wet hill forest, montane forest, moss forest and some swamp forest.
Bentuang Karimun National Park is a valuable site for Bornean biodiversity, not only for its numerous endangered species, but undoubtedly for many more as yet undiscovered plants and animals. Initial surveys have discovered thousands of species of flora and fauna, including as many as 250 bird species and seven primates species.
Indigenous inhabitants of the region include a variety of Dayak tribes, who live from hunting, collecting forest products and subsistence farming based on a pattern of shifting cultivation.
Threats to the parks and the local people’s traditional way of life include logging, illegal gold-mining and commercial extraction of forest products at unsustainable levels.
Bentuang Karimun can be accessed by land, air and water from Putussibau, which can be reached from Pontianak by bus, boat or plane.
From Putussibau:
* Land: Badau-bound buses can drop you at Sadap village, from where longboats can be hired to the park’s richest wildlife area along the Embaloh River. The local Ibans also act as guides.
* Air: The MAF flight from Putussibau to Tanjung Lokang inside the park takes about 25 minutes.
* Water: Longboat by way of the Kapuas river to Tanjung Lokang. The part between Nanga Lapung and Tanjung Lokang has five rapids and isn’t recommended to the faint-hearted.
* Water: Longboat from Putussibau to the Nanga Menyakan area through the Sibau River.
There’s no official accommodation as yet.

Topographically, Betung Kerihun National Park is hilly. The Muller range which connects Mt. Betung and Mt. Kerihun also forms the border between Indonesia and Serawak, 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.

The Park has eight types of forest ecosystem 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.

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 bird in this Park are the wreathed hornbill (Aceros undulatus) and the helmeted hornbill (Rhinoplax vigil) which is the mascot of West Kalimantan.

The Park has been proposed as a Trans-Border Reserve together with Lantjak Entimau Wildlife Reserve in Serawak.

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.

Interesting locations/attractions:

The Muller Range: this forms part of the national border. Mt. Kerihun and Mt. Betung are good places for climbing.
Tekelan, Sibau, Mendalam, Embaloh, Kanyau rivers: kayaking/canoeing, observing animals and plants, and cultural tourism.
Riam Lapan and Riam Matahari: hardy souls can test their whitewater rafting skills on numerous rapids, rated at class III-IV in difficulty, climaxing at class V in Riam Matahari.
Sedik, Batang Pilung and Jaan rivers: waterfalls, observing animals and plants, and cultural tourism.
Tanjung Lokang: located in the western part of the Park, there are steep slopes and limestone caves suitable for caving. Also sites of cultural interest.

Best time of year to visit: September to December.

How to reach the Park: Pontianak-Putussibau by four wheel drive, about 18 hours; or by small plane (Cessna), about 2.5 hours. Then, from Putussibau along the Kapuas, Sibau and Mendalam rivers by semi-longboat, about 5 hours, or alternatively, from Putussibau up the Kapuas and Embaloh Hulu rivers by speed boat, about 3 hours; and then up the Embaloh Hulu river by semi-longboat, about 9 hours.

Note: During dry season, especially in January or August the journey to the park will be longer.
This Park is the sister park to the Lanjak Entimau Nature Reserve in Sarawak. The diffrent type of ecosystem and the variety of its topography makes this park very unique. The three types of rainforest from the lowland to the upland described the variety of the flora of this park.
The dominant fauna in the park is the Orang Utan (Pongo pygmaeus) and the dominant bird is the Hornbill. The Dayak – the hinterland people of Kalimantan live around this park. One of their unique habit is to make ” Tattoo ” on their skin.

The East Malaysian State of Sarawak on the island of Borneo possesses forests extremely rich in tropical hardwoods. With about 60% of its land area still under forest cover, Sarawak has a thriving timber industry. During the 1980s, concerns were raised about the sustainability of the use of these forests and the conservation of the State’s vast biological diversity. Thus, in 1989, the Government of Malaysia invited ITTO to send a delegation to Sarawak assess the sustainable utilsation and conservation of tropical forests there and to make recommendations for further strength-ening sustainable forest management policies and practices. One of the recommendations of the resulting Mission report in 1990 was that the conservation of forest biodiversity was best served through in situ preservation of that heritage. The report went on to suggest, specifically, that Lanjak-Entimau, a wildlife sanctuary of approximately 170,000 hectares in southwestern Sarawak, be given priority for development as a Totally Protected Area. The Sanctuary had been gazetted in 1983, primarily as an orangutan reserve, but had remained relatively uncharted territory since that time.

In response to this recommendation, in 1992 a combined team of international and local consultants, as well as staff from the Sarawak Forest Department, set out to conduct inventories of Lanjak-Entimau’s major geographical, geological, floral and faunal characteristics, and to obtain information concerning the livelihoods and attitudes of the native peoples residing near the Sanctuary. This formed the basis of the ITTO project PD106/90. Fieldwork for the first phase of the project was initiated in mid-1993 with visits by researchers comprising a forest botanist, a primatologist, an ornithologist, a herpetologist, an entomologist, a soils expert and a sociologist.

Development of Lanjak-Entimau Wildlife Sanctuary as a Totally Protected Area has been crucial to the conservation of tropical biodiversity, not only because of the richness of its own flora and fauna, but even more so because of its links to the Bentuang Karimun National Park in West Kalimantan, Indonesia (see Box). Their combined areas of almost one million hectares, form one of the world’s largest transboundary, biodiversity reserves in humid tropical forest.

Species Richness

Phase I of Project 106/90 was completed in mid-1994 and following submission of the consultants’ report, a picture of the unique natural history of Lanjak-Entimau began to emerge. More than 1,000 species of trees (> 10 cm diameter) were found, making the area among the most floristically rich sites studied in Borneo. There is such an abundance of valuable timber species that the forest ecologist on the team has designated several areas as gene banks or seed sources for the future. In addition, botanical surveys in cooperation with the Kedayan, Lun Bawang and local Iban people have recorded 140 species of plants used in traditional medicine and at least 114 locally consumed varieties of wild fruits and vegetables. Specimens of South-East Asia’s giant parasitic flower, the Rafflesia, were also reported from the southern areas of Lanjak-Entimau.

Faunal survey results have been equally exciting. The number of orangutans in the Sanctuary is estimated to be more than 1,000 individuals, while the population of Bornean gibbons is understood to exceed 20,000. This gives Lanjak-Entimau the highest known population density of the species ever recorded in Borneo. Birds are also abundant with over 200 species recorded, including the rare Bulwer’s pheasant, seven of the eight species of hornbills known from Sarawak, and about half of the bird species known to be endemic to Borneo. Herpetofaunal surveys recorded a total of 78 different species, of which one was extremely rare and at least four others have been found to be new to science. Casual collections of fish from several streams in the Sanctuary recorded 36 species, of which two are previously undescribed, and a collection of crabs from both freshwater and forest floor habitats resulted in the discovery of one new genus and three new species.

Local Support

Interviews by the project sociologist among 102 communities residing on the periphery of the Lanjak-Entimau area provided a coherent picture of their needs and aspirations and the ways in which they view the Sanctuary and its development as a Totally Protected Area. Under the 1983 gazettement, some have enjoyed special rights to gather forest products from designated areas within the Sanctuary. They also hunt on the boundary areas, predominantly for wild boar (Sus barbatus) and, to a lesser extent, for deer (Cervus unicolor) for meat. Though poverty does touch them, they retain a positive view of the Lanjak-Entimau Sanctuary as a source of stability and sustenance. Interviews indicated that a majority polled (70 per cent) expressed support for preservation of the Sanctuary, strict enforcement of the laws protecting it and a programme by which communities near the boundary can exercise control over entry into the Protected Area.

Permanent Facilities

This year, Phase II of the Lanjak-Entimau project will see the initiation of infrastructural, scientific and community development within the Sanctuary. A headquarters, a well-equipped research station and new ranger facilities will be erected at strategic entry points on the Sanctuary’s boundaries. Scientific biodiversity inventories, both new and extended from Phase I will begin on ethnobotany, mycology, canopy invertebrates, fish and important game species. Integrated into these projects will be a training and educational programme for staff members of the Sarawak Forest Department and participants from local communities. The purpose of this programme will be to increase the level of technical expertise for the long-term development of biodiversity based resources from forested areas in the buffer zone adjoining the Sanctuary. Special emphasis will be given to the development of gene banks for economically important timber species, cultivation of non-timber forest products such as rattan, ethno-botanical gardens for cultivation of medicinal plants by local people and management of game and fish populations to ensure sustainable long-term use.

These integrated research and training programmes will be implemented in close cooperation with the proposed Centre for Biodiversity Conservation to be established in Kuching next year. Primarily, this will be a depository for Sarawak’s collections of plant and animal specimens. It is envisaged that the Centre will also plan, coordinate and undertake research on biodiversity and, with the Sarawak Forest Department, will be able to take on projects initiated in the Lanjak-Entimau Wildlife Sanctuary following completion of Phase II.

The Lanjak-Entimau project has proved to be even more exciting than was ever anticipated. In a decade the Sanctuary has evolved from a remote and unknown orangutan reserve to hold status as one of the equatorial world’s richest known centres for tropical biodiversity conservation.
