Danum Valley Conservation Area
Danum Valley Conservation Area is a 438 square kilometres tract of relatively undisturbed lowland dipterocarp forest in Sabah, Malaysia. It has an extensive diversity of tropical flora and fauna, including such species as the rare Bornean orangutans, gibbons, mousedeer, clouded leopards and over 270 bird species. Activities offered are jungle treks, river swimming, bird watching, night jungle tours and excursions to nearby logging sites and timber mills. The area holds unique status in the sense that before it became a conservation area there were no human settlements within the area, meaning that hunting, logging and other human interference was non existent making the area almost unique. It is managed by Yayasan Sabah for conservation, research, education, and habitat restoration training purposes. There have been proposals to nominate the site as a UNESCO World Heritage Site.

Borneo
Borneo (; id, Kalimantan) is the third-largest island in the world and the largest in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra. The island is politically divided among three countries: Malaysia and Brunei in the north, and Indonesia to the south. Approximately 73% of the island is Indonesian territory. In the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The population in Borneo is 23,053,723 (2020 national censuses). Additionally, the Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. The sovereign state of Brunei, located on the north coast, comprises about 1% of Borneo's land area. A little more than half of the island is in the Northern Hemisphere, including Brunei and the Malaysian portion, while the Indonesian portion spans the Northern and Southern hemisph ...

Horsfield's Tarsier
Horsfield's tarsier (''Cephalopachus bancanus''), also known as the western tarsier, is the only species of tarsier in the genus ''Cephalopachus''. Named for American naturalist Thomas Horsfield, it occurs on Borneo, Sumatra and nearby islands and is, like other members of the group, entirely nocturnal. Taxonomy Although Horsfield's tarsier was usually placed in the genus ''Tarsius'' with all other living tarsiers, it is quite distinct from the Philippine tarsier and the various tarsiers of Sulawesi and nearby islands; therefore, scientists have placed it in a separate genus, ''Cephalopachus''. The taxonomy of this species is in doubt, with some subspecies considered unsure. In fact, over 20 years few studies have been done on ''C. bancanus'' and a taxonomic revision based upon intensive and systematic field surveys is overdue. The IUCN believes that these subspecies should be treated as distinct and named as separate taxa until more definitive evidence is available. When ...

Dipterocarpus Caudatus
''Dipterocarpus caudatus'' is a species of plant in the evergreen or semi-evergreen family Dipterocarpaceae. The species name is derived from Latin (' = tailed) and refers to the narrow acumen of the leaf apex. It is an emergent tree, up to 50 m tall, in mixed dipterocarp forest on dry ridges. It is found within Sumatra, coastal Peninsular Malaysia, Singapore and Borneo. It is a medium hardwood sold under the trade names of Keruing. It was formerly most abundant along the coastal hills on sandy soils, but is endangered due to land conversion. ''D. caudatus'' is found in at least one protected area (Sepilok Sepilok Orangutan Rehabilitation Centre is located about 25 kilometres west of Sandakan in the state of Sabah, Malaysia.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dipterocarpus
'' D. retusus'' in Köhler ''Dipterocarpus'' is a genus of flowering plants and the type genus of family Dipterocarpaceae. ''Dipterocarpus'' is the third-largest and most diverse genus among the Dipterocarpaceae. The species are well known for timber, but less acknowledged for use in traditional herbal medicine. The genus has about 70 species, occurring in South Asia and Southeast Asia, from Sri Lanka and India to the Philippines. It is an important component of dipterocarp forests. Its generic name comes from Greek and means "two-winged fruits". The greatest diversity of ''Dipterocarpus'' species occurs on Borneo, with many endemic to the island. The oldest fossil of the genus, and Dipterocarpaceae, is from the latest Cretaceous (Maastrichtian) Intertrappean Beds of India. Uses The genus is of considerable importance as timber trees, sold under the trade name Keruing, although not as important as ''Shorea'' species.

Borneo Lowland Rain Forest
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. Location and description The World Wildlife Fund has divided Borneo into seven ecoregions: five areas of lowland forest; the central Borneo montane rain forests; and the Kinabalu montane alpine meadows. The lowlands are distinguished by climate (as the eastern side of the island is drier) or separated by the large Kapuas River and Barito River, which prevent animals and reptiles from spreading freely around the island. The other lowland ecoregions, in addition to the Borneo lowland rain forests, are: *Borneo peat swamp forests *Sundaland heath forests * Southwest Borneo freshwater swamp forests * Sunda Shelf mangr ...

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...

Bornean Rhinoceros
The Bornean rhinoceros (''Dicerorhinus sumatrensis harrissoni''), also known as the eastern Sumatran rhinoceros or eastern hairy rhinoceros, is one of three subspecies of Sumatran rhinoceros. The subspecies may be functionally extinct, with only one individual, a female named Pahu, surviving in captivity, and held in the state of Sabah. In April 2015, the Malaysian government declared the Bornean rhinoceros to be extinct in the wild in the Malaysian portion of Borneo. However, in March 2016, a young female rhino was captured in East Kalimantan (in the Indonesian portion of Borneo), providing evidence of their continued existence.http://news.nationalgeographic.com/2016/03/160324-sumatran-rhino-borneo-indonesia-kalimantan-endangered-species/ The International Union for Conservation of Nature (IUCN) classifies the subspecies as critically endangered. Taxonomy The Bornean subspecies ''Dicerorhinus sumatrensis harrissoni'', was named in honour of the British polymath Tom Harrisson, wh ...
