The Sulawesi montane rain forests is a tropical moist forest ecoregion in Indonesia. It includes the highlands of Sulawesi. [2] [3] [4]
Sulawesi, with an area of 180,681 km², is the fourth-largest island in Indonesia, and the eleventh-largest in the world. The landmass of Sulawesi includes four peninsulas: the northern Minahasa Peninsula, the East Peninsula, the South Peninsula, and the Southeast Peninsula. The island is mountainous, and the highest peak is Mount Latimojong at 3,478 meters. Approximately 40% of Sulawesi's land area is in the montane rain forests ecoregion; the surrounding lowlands are in the Sulawesi lowland rain forests ecoregion.
The islands that make up the ecoregion are part of Wallacea, a group of islands that are part of the Australasian realm, but were never joined to either the Australian or Asian continents. The islands of Wallacea are home to a mix of plants and animals from both terrestrial realms, and have many unique species that evolved in isolation. [5] The Makassar Strait separates Sulawesi from Borneo to the west; the strait is part of the Wallace Line, which demarcates the western boundary of Wallacea. Borneo and the other Indonesian islands west of Sulawesi are part of Sundaland, and were connected to the Asian continent when sea levels were lower during the ice ages.
The ecoregion has a wet tropical montane climate. [5]
The main plant communities are lower montane rain forest, upper montane rain forest, and sub-alpine forests. The forests generally form a closed canopy, and height decreases with elevation. [5]
Lower montane rain forest, or sub-montane forest, ranges from 1000 to 1500 meters elevation. Trees in the beech family (Fagaceae) are predominant, including four species of Lithocarpus and two species of Castanopsis ( Castanopsis acuminatissima and C. buruana ). Other trees include Eugenia , along with trees in the myrtle family (Myrtaceae), laurel family (Lauraceae), and tea family (Theaceae) and the conifers Agathis dammara and Phyllocladus . Epiphytes including orchids are common. In the mid-montane forests (1500-2000 meters elevation) Fagaceae, especially Lithocarpus menadoensis and L. celebicus , Myrtaceae, and Agathis are predominant. [6]
Upper montane forests are characterized by conifers, including species of Agathis, Podocarpus, Dacrycarpus, Dacrydium , and Phyllocladus, together with Myrtaceae and the shrubs Rhododendron, Vaccinium, Gaultheria , and Tasmannia piperita . Fagaceae are less common than in the lower-elevation forests. Mosses become abundant over 2000 meters elevation. [6] [5]
Sub-alpine communities form above 3200 meters elevation, with low trees and shrubs, principally Rhododendron, Decaspermum , and Hedyotis , along with the lower shrubs Gaultheria and Acrothamnus suaveolens . The trees and shrubs are festooned with lichens. Herbs include the daisy Keysseria , the ginger Alpinia , Potentilla leuconata and P. parvus, and the grasses Poa and Agrostis . [5] [7]
The ecoregion is home to 102 mammal species, a third of which are endemic or near-endemic. 24 mammal species are endemic to the ecoregion, and 10 are near-endemic. [5]
Larger mammals include two pigs, the Celebes warty pig (Sus celebensis) and North Sulawesi babirusa (Babyrousa celebensis). The Celebes warty pig lives in the lower montane and lowland rain forests of Sulawesi and other islands of Wallacea. The North Sulawesi babirusa lives in both the montane and lowland rain forests of northern and central Sulawesi. The endemic Mountain anoa (Bubalus quarlesi) is a dwarf buffalo which stands only 70 cm (28 in) high. The Celebes rusa deer (Rusa timorensis macassaricus) is a subspecies of the Javan rusa, which may have been introduced from Sundaland to Sulawesi by humans in ancient times. [8]
There are two endemic arboreal primates, Dian's tarsier (Tarsius dentatus) and the Pygmy tarsier (Tarsius pumilus). [5]
The majority of endemic species are rodents, including three squirrels and 17 Murid rodents: [5]
Another ten species are Sulawesi endemics, which live in both the montane and lowland rain forests ecoregions: [5]
The Bola Batu babirusa (Babyrousa bolabatuensis), known only from bones, is recognized as a separate species. No living individuals have been recorded, and the species may be extinct.
The ecoregion is home to 168 bird species. 19 species are endemic to the ecoregion, and another 23 are near-endemic. [5]
A 2017 assessment found that 9,066 km², or 12%, of the ecoregion is in protected areas. [1]
Protected areas in or partly in the ecoregion include: [3]
Sulawesi, also known as Celebes, is an island in Indonesia. One of the four Greater Sunda Islands, and the world's 11th-largest island, it is situated east of Borneo, west of the Maluku Islands, and south of Mindanao and the Sulu Archipelago. Within Indonesia, only Sumatra, Borneo, and Papua are larger in territory, and only Java and Sumatra are more populous.
The North Sulawesi babirusa is a pig-like animal native to Sulawesi and some nearby islands in Indonesia. It has two pairs of large tusks composed of enlarged canine teeth. The upper canines penetrate the top of the snout, curving back toward the forehead. The North Sulawesi babirusa is threatened from hunting and deforestation.
Wallacea is a biogeographical designation for a group of mainly Indonesian islands separated by deep-water straits from the Asian and Australian continental shelves. Wallacea includes Sulawesi, the largest island in the group, as well as Lombok, Sumbawa, Flores, Sumba, Timor, Halmahera, Buru, Seram, and many smaller islands. The islands of Wallacea lie between the Sunda Shelf to the west, and the Sahul Shelf including Australia and New Guinea to the south and east. The total land area of Wallacea is 347,000 km2 (134,000 sq mi).
The Sundaland heath forests, also known as Kerangas forest, is a type of tropical moist forest found on the island of Borneo, which is divided between Brunei, Indonesia, and Malaysia, as well as on the Indonesian islands of Belitung and Bangka, which lie to the west of Borneo.
The babirusas, also called deer-pigs, are a genus, Babyrousa, in the swine family found in the Indonesian islands of Sulawesi, Togian, Sula and Buru. All members of this genus were considered part of a single species until 2002, the babirusa, B. babyrussa, but following that was split into several species. This scientific name is restricted to the Buru babirusa from Buru and Sula, whereas the best-known species, the North Sulawesi babirusa, is named B. celebensis. The remarkable "prehistoric" appearance of these mammals is largely due to the prominent upwards incurving canine tusks of the males, which pierce the flesh in the snout.
Lore Lindu National Park is a protected area of forest on the Indonesian island of Sulawesi, in the province of Central Sulawesi. The Indonesian national park is 2,180 km2 covering both lowland and montane forests. It provides habitat to numerous rare species, including 77 bird species endemic to Sulawesi. The national park is designated as part of the UNESCO World Network of Biosphere Reserves. In addition to its rich wildlife, the park also contains megaliths dating from before 1300 AD.
The wildlife of Cameroon is composed of its flora and fauna. Bordering Nigeria, it is considered one of the wettest parts of Africa and records Africa's second highest concentration of biodiversity. To preserve its wildlife, Cameroon has more than 20 protected reserves comprising national parks, zoos, forest reserves and sanctuaries. The protected areas were first created in the northern region under the colonial administration in 1932; the first two reserves established were Mozogo Gokoro Reserve and the Bénoué Reserve, which was followed by the Waza Reserve on 24 March 1934. The coverage of reserves was initially about 4 percent of the country's area, rising to 12 percent; the administration proposes to cover 30 percent of the land area.
The Buru babirusa is a wild pig-like animal native to the Indonesian islands of Buru, the two Sula Islands of Mangole and Taliabu. It is also known as the Moluccan babirusa, golden babirusa or hairy babirusa. Traditionally, this relatively small species included the other babirusas as subspecies, but it has been recommended treating them as separate species based on differences in their morphology. As also suggested by its alternative common names, the Buru babirusa has relatively long thick, gold-brown body-hair – a feature not shared by the other extant babirusas.
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.
The Central Range montane rain forests is a tropical moist forest ecoregion on the island of New Guinea. The ecoregion covers the Central Range of the New Guinea Highlands, which extends along the spine of the island. The montane rain forests of the ecoregion are distinct from the surrounding lowland forests, and are home to many endemic plants and animals.
The Central Range sub-alpine grasslands is a montane grasslands and shrublands ecoregion on the island of New Guinea. The ecoregion covers the highest-elevation portions of the New Guinea Highlands, which extend along the spine of the island. The high elevations support rare tropical sub-alpine and alpine habitats, including many endemic plants and animals.
The Lesser Sundas deciduous forests is a tropical dry forest ecoregion in Indonesia. The ecoregion includes the islands of Lombok, Sumbawa, Komodo, Flores, and Alor, along with the many adjacent smaller islands.
The Timor and Wetar deciduous forests is a tropical dry forest ecoregion in Indonesia and East Timor. The ecoregion includes the islands of Timor, Wetar, Rote, Savu, and adjacent smaller islands.
The Borneo montane rain forests is an ecoregion on the island of Borneo in Southeast Asia. It includes montane tropical and subtropical moist broadleaf forests, also known as a cloud forests. The ecoregion is partly in East Malaysia and Indonesia (Kalimantan).
