The Lake Sentarum National Park (Indonesian : Taman Nasional Danau Sentarum) is a national park protecting one of the world's most biodiverse lake systems, [2] located in the heart of Borneo Island, Kapuas Hulu Regency, West Kalimantan Province, Indonesia. It lies in the upper Kapuas River tectonic basin some 700 kilometres upstream from the delta. The basin is a vast floodplain, consisting of about 20 seasonal lakes, freshwater swamp forest and peat swamp forest. Local people call it as Lebak lebung (floodplain). [3] The National Park is located in the western part of this basin, where three-quarters of the seasonal lakes occur. Approximately half of the park consists of lakes, while the other half consists of freshwater swamp forest.
An area of 800 km2 was first gazetted as Wildlife Reserve in 1982, which in 1994 was extended to 1,320 km2 (890 km2 is swamp forest area and 430 km2 is dry-land) [3] when it became a Ramsar site. In 1999 it was declared a National Park, however a National Park Authority was only established in 2006. [4]
Danau Sentarum National Park has a rich fish fauna with around 240 recorded species, including the Asian arowana and clown loach botia. During a biological expedition, scientists found species of such fish genera as Chitala , Scleropages , Chitala , Channa , Leptobarbus , Parachela , including many new species. [5] There have been 237 bird species recorded including the Storm's stork and great argus. Of the 143 mammal species 23 are endemic to Borneo including the proboscis monkey. There is a relatively large population of the endangered orangutans present in the park. The 26 reptile species include the false gharial and estuarine crocodile. [6]
The lakes support a large traditional fishing industry. The western part of the upper Kapuas floodplain is inhabited by almost 20,000 people, 88% of which are Malay fishermen. About 3,000 people live in about 20 village enclaves within the Park.
A swamp is a forested wetland. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates periodic inundation or soil saturation. The two main types of swamp are "true" or swamp forests and "transitional" or shrub swamps. In the boreal regions of Canada, the word swamp is colloquially used for what is more formally termed a bog, fen, or muskeg. Some of the world's largest swamps are found along major rivers such as the Amazon, the Mississippi, and the Congo.
The Asian arowana comprises several phenotypic varieties of freshwater fish distributed geographically across Southeast Asia. While most consider the different varieties to belong to a single species, work by Pouyaud et al. (2003) differentiates these varieties into multiple species. They have several other common names, including Asian bonytongue, dragonfish, and a number of names specific to the different color varieties.
West Kalimantan is a province of Indonesia. It is one of five Indonesian provinces comprising Kalimantan, the Indonesian part of the island of Borneo. Its capital city is Pontianak. The province has an area of 147,307 km2, and had a population of 4,395,983 at the 2010 Census and 5,414,390 at the 2020 Census; the official estimate as at mid 2021 was 5,470,797. Ethnic groups include the Dayak, Malay, Chinese, Javanese, Bugis, and Madurese. The borders of West Kalimantan roughly trace the mountain ranges surrounding the vast watershed of the Kapuas River, which drains most of the province. The province shares land borders with Central Kalimantan to the southeast, East Kalimantan to the east, and the Malaysian territory of Sarawak to the north.
The proboscis monkey or long-nosed monkey is an arboreal Old World monkey with an unusually large nose, a reddish-brown skin color and a long tail. It is endemic to the southeast Asian island of Borneo and is found mostly in mangrove forests and on the coastal areas of the island.
The Mahakam River is third longest and volume discharge river in Borneo after Kapuas River and Barito River, it is located in Kalimantan, Indonesia. It flows 980 kilometers from the district of Long Apari in the highlands of Borneo, to its mouth at the Makassar Strait.
The Kapuas River is a river in the Indonesian part of Borneo island, at the geographic center of Maritime Southeast Asia. At 1,143 kilometers (710 mi) in length, it is the longest river in the island of Borneo and the longest river of Indonesia and one of the world's longest island rivers. It originates in the Müller mountain range at the center of the island and flows west into the South China Sea creating an extended marshy delta. The delta is located west-southwest of Pontianak, the capital of the West Kalimantan province. This Kapuas River should be distinguished from another Kapuas River, which starts on the other side of the same mountain range in central Borneo, but flows to the south, merging with the Barito River and discharging into the Java Sea.
Kapuas Hulu Regency is a regency in West Kalimantan province of Indonesia. Located around Kapuas River, it has a total area of 29,842.03 square kilometres or around 20.26% of West Kalimantan province's area. The regency seat is located in town of Putussibau, where most of its economic and government activities take place. Due to its relatively large area, it is sparsely populated compared to neighbouring regencies around it. The regency had a population of 222,160 at the 2010 Census and 252,609 according to the 2020 Census; the official estimate as at mid 2021 was 253,740.
The Borneo peat swamp forests ecoregion, within the tropical and subtropical moist broadleaf forests biome, are on the island of Borneo, which is divided between Brunei, Indonesia and Malaysia.
Pangsuma Airport is an airport in Putussibau, West Kalimantan, Indonesia. The distance between the Airport and Putussibau is 3.7 km via Jl. Lintas Kalimantan Poros Utara. Putussibau is the capital of Kapuas Hulu within approximately 400 km from Pontianak. The town is the gateway to the two major eco-tourism destinations in the heart of Borneo, Danau Sentarum National Park and Betung Kerihun National Park.
The Malagarasi River is a river in western Tanzania, flowing through Kigoma Region, although one of its tributaries comes from southeastern Burundi. The river also forms the western border of Tabora Region, the southern border of Kagera Region and the southwestern border of Geita Region. It is the second-longest river in Tanzania behind the Rufiji—Great Ruaha, and has the largest watershed of any river flowing into Lake Tanganyika. The Malagarasi-Muyovozi Wetlands are a designated a Ramsar site. Local tribes have nicknamed the Malagarasi as "the river of bad spirits".
Betung Kerihun National Park is a national park located in the Indonesian province of West Kalimantan, on the island of Borneo. The park was established in 1995, and has a total area of 8,000 km2 (3,100 sq mi) or about 5.5 percent of West Kalimantan Province area. Together with the 2,000 km2 (800 sq mi) Lanjak Entimau Wildlife Sanctuary in Malaysia, it has been proposed to form a World Heritage Site named the "Transborder Rainforest Heritage of Borneo".
The Kahayan river, or Great Dayak River, is the second largest river after Barito River in Central Kalimantan, a province of Indonesia in Kalimantan – the Indonesian part of the island of Borneo. With a total length of 658 km (409 mi) and with a drainage basin of 15,500 km2 (6,000 sq mi) in South Kalimantan, Indonesia. Mean annual discharge 1,178 m3/s (41,600 cu ft/s). The provincial capital Palangkaraya lies on the river. The main inhabitants are Dayaks, who practice slash-and-burn rice cultivation and pan for gold on the upper reaches. The lower Kayahan flows through a rich and unusual environment of peat swamp forests, which has been severely degraded by an unsuccessful program to convert a large part of the area into rice paddies, compounded by legal and illegal forestry.
Classification of wetlands has been a problematical task, with the commonly accepted definition of what constitutes a wetland being among the major difficulties. A number of national wetland classifications exist. In the 1970s, the Ramsar Convention on Wetlands of International Importance introduced a first attempt to establish an internationally acceptable wetland classification scheme.
The Borneo lowland rain forests is an ecoregion, within the tropical and subtropical moist broadleaf forests biome, of the large island of Borneo in Southeast Asia. It supports approximately 15,000 plant species, 380 bird species and several mammal species. The Borneo lowland rain forests is diminishing due to logging, hunting and conversion to commercial land use.
Kutai National Park is a lowland national park located on the east coast of Borneo Island, in the East Kalimantan province of Indonesia, ranging approximately 10 to 50 km north of the equator.
The Wasur National Park forms part of the largest wetland in Merauke Regency, South Papua, Indonesia and has been one of the least disturbed by human activity. The high value of its biodiversity has led to the park being dubbed the "Serengeti of Papua". The vast open wetland, in particular Rawa Biru Lake, attracts a very rich fauna.
The greater scissortail is a species of ray-finned fish in the genus Rasbora. It inhabits forest creeks in Malaysia, Indonesia and the lower Mekong basin.
Leptobarbus melanopterus is a species of cyprinid fish in the genus Leptobarbus known only from the Kapuas River basin in Western Borneo. Locally it is called Jelawat pipi merah, when translated means Red Cheeked Sultan Fish, they are also called blood carp by aquarium hobbyists due to their vibrant red cheeks.
Igapó is a word used in Brazil for blackwater-flooded forests in the Amazon biome. These forests and similar swamp forests are seasonally inundated with freshwater. They typically occur along the lower reaches of rivers and around freshwater lakes. Freshwater swamp forests are found in a range of climate zones, from boreal through temperate and subtropical to tropical. In the Amazon Basin of Brazil, a seasonally whitewater-flooded forest is known as a várzea, which is similar to igapó in many regards; the key difference between the two habitats is in the type of water that floods the forest.
The Heart of Borneo is a conservation agreement initiated by the World Wide Fund for Nature to protect a 220,000 km² forested region on Borneo island. The agreement was signed by the governments of Brunei, Indonesia and Malaysia in Bali on 12 February 2007 to support the initiative. The region provides habitat to 10 endemic species of primates, more than 350 birds, 150 reptiles and amphibians and 10,000 plants. From 2007 to 2010 a total of 123 new species have been recorded in the region. A status report from 2012 found that the lowland rain forest within the area is deteriorating and under threat. The Bornean rhinoceros was the most threatened fauna, in 2015 three captive individuals remained in Sabah.
