The wildlife of Singapore is surprisingly diverse despite its rapid urbanisation. The majority of fauna that remain on the island exist in nature reserves such as the Bukit Timah Nature Reserve and the Sungei Buloh Wetland Reserve. [1]
In 1819, Singapore was mostly covered in rainforests. During that time, it still contained flora shared with the Malay Peninsula, but even then, the biodiversity of fauna was relatively low. Following the establishment of the British trading post, rapid deforestation began due to crop cultivation, and was largely completed by the 20th century. By some estimates, there has been a loss of 95% of the natural habitats of Singapore over the course of the past 183 years. [2] Due to the deforestation, over 20 species of freshwater fish, 100 species of bird, and a number of mammals became locally extinct. [3] A 2003 estimate put the proportion of extinct species as over 28%. [4]
In modern times, over half of the naturally occurring fauna and flora in Singapore is present only in nature reserves, which comprise only 0.25% of Singapore's land area. [2] Estimates made in 2003 have said that the rapid habitat destruction will culminate in a loss of 13-42% of populations in all of Southeast Asia. [5] To combat these problems, the Singaporean government made the Singapore Green Plan in 1992 and the new Singapore Green Plan in 2012 to continue it. The plan aims to keep tabs on the unstable populations of fauna and flora, to place new nature parks, and to connect existing parks. In addition, there were plans to set up a National Biodiversity Reference Centre (now known as the National Biodiversity Centre). [6] The last goal was reached in 2006 when the centre was founded (it also accomplished the establishment of two new nature reserves in 2002 [7] ). Since its foundation it has been formulating various specific initiatives including attempts to conserve the hornbill and the rare dragonfly Indothemis limbata . [8]
Singapore has roughly 80 species of mammals (out of 11 different orders) including 45 species of bats and three species of non-human primates. [9] Currently the only introduced non-domestic mammal species in Singapore is the variable squirrel. [10] The abundance of bats however has been decreasing rapidly due to habitat loss of over 95%. [11]
Singapore is the occasional home of 395 species of birds (out of which roughly 180 species are resident). [12]
Singapore contains a relatively large number of reptiles, a total of about 110 species (4 of which are introduced). [13] Most of the species, roughly 75 are snakes (mainly Colubrid snakes). [14]
Singapore has 30 species of amphibians (out of which two species, the painted bull frog and the American bullfrog, are introduced). [15]
Singapore currently contains 1358 known species of native vascular plants, of which approximately 759 are critically endangered. [16]
Singapore's land area is dominated by urban development that is interspaced by natural reserves, waterways, parks and a large interlinked network of over 300 km of park connectors (PCN). [17] The indigenous fauna that has adapted to the urban environment includes the following:
Other wildlife sightings include the following:
The Bukit Timah Nature Reserve is a 1.7-square-kilometre (0.66 sq mi) nature reserve near the geographic centre of Singapore, located on the slopes of Bukit Timah Hill, the country's highest natural peak standing at a height of approximately 165 metres (541 ft), and parts of the surrounding area, located actually in Bukit Panjang. The nature reserve is about 15 kilometres from the Downtown Core, Singapore's central business district (CBD).
The Central Catchment Nature Reserve is the largest nature reserve in Singapore, occupying 2880 hectares. Forming a large green lung in the geographical centre of the city, it houses several recreational sites, including the Singapore Zoo, the Night Safari and the River Safari, as well as several newer facilities built to encourage public appreciation of the reserve, such as the HSBC TreeTop Walk. The reserve sits within the boundaries of the Central Water Catchment. It is one of the four gazetted nature reserves in Singapore. The other three are the Labrador Nature Reserve which was gazetted since 1 January 2002, Sungei Buloh Wetland Reserve and Bukit Timah Nature Reserve. All four nature reserves along with the parks are protected under the Parks & Trees Act 2005.
Satpura Tiger Reserve (STR) also known as Satpura National Park is located in the Narmadapuram district of Madhya Pradesh in India. Its name is derived from the Satpura range. It covers an area of 524 km2 (202 sq mi). Satpura National Park, along with the adjoining Bori and Pachmarhi wildlife sanctuaries, provides 2,200 km2 (850 sq mi) of unique central Indian highland ecosystem. It was set up in 1981.
Kali Tiger Reserve is a protected area and tiger reserve. It is located in Uttara Kannada district, in Karnataka, India. The park is a habitat of Bengal tigers, black panthers and Indian elephants, amongst other distinctive fauna. The Kali River flows through the tiger reserve and is the lifeline of the ecosystem and hence the name. The tiger reserve is spread over an area of 1300 square kilometres.
Cúc Phương National Park is located in Ninh Bình Province, in Vietnam's Red River Delta. Cuc Phuong was Vietnam's first national park and is the country's largest nature reserve. The park is one of the most important sites for biodiversity in Vietnam.
Tengku Hassanal Wildlife Reserve is one of the largest wildlife reserves in Peninsular Malaysia covering 605.52 km2 located in the Titiwangsa Mountains, central state of Pahang, Malaysia that was established during the British Colonial Administration. It was officially gazetted to protect all wildlife species, particularly the gaur. The administrative offices of the reserve are located in several places. The main office is located in Bukit Rengit, and the other stations are in Lembah Klau, Kuala Lompat, and Perlok.
Manas National Park is a national park, Project Tiger reserve, and an elephant reserve in Assam, India. Located in the Himalayan foothills, it borders the Royal Manas National Park in Bhutan. The park is known for its rare and endangered endemic wildlife such as the Assam roofed turtle, hispid hare, golden langur and pygmy hog. Manas is also famous for its population of the wild water buffalo. Because of its exceptional biodiversity, scenery, and variety of habitats, Manas National Park is a biosphere reserve and a UNESCO World Heritage Site.
The wildlife of Malaysia is diverse, with Malaysia being a megadiverse country. Most of the country is covered in rainforest, which hosts a huge diversity of plant and animal species. There are approximately 361 mammal species, 694 bird species, 250 reptile species, and 150 frog species found in Malaysia. Its large marine territory also holds a great diversity of life, with the country's coastal waters comprising part of the Coral Triangle.
The wildlife of the Democratic Republic of the Congo includes its flora and fauna, comprising a large biodiversity in rainforests, seasonally flooded forests and grasslands.
The state of Karnataka in South India has a rich diversity of flora and fauna. It has a recorded forest area of 38,720 km2 which constitutes 55 of the geographical area of the state. These forests support 25% of the elephant population and 20% of the tiger population of India. Many regions of Karnataka are still unexplored and new species of flora and fauna are still found. The mountains of the Western Ghats in the western region of Karnataka are a biodiversity hotspot. Two sub-clusters of the Western Ghats, Talacauvery and Kudremukh, are on a tentative list of sites that could be designated as World Heritage Sites by UNESCO. The Bandipur and Nagarahole national parks which fall outside these subclusters were included in the Nilgiri biosphere reserve in 1986, a UNESCO designation. In the Biligiriranga Hills the Eastern Ghats meet the Western Ghats. The state bird and state animal of Karnataka are Indian roller and the Indian elephant. The state tree and state flower are sandalwood and lotus. Karnataka is home to 524 tigers.
The Raffles' banded langur, also known as the banded leaf monkey or banded surili, is a species of primate in the family Cercopithecidae. It is endemic to Singapore and southern Peninsular Malaysia. The species underwent taxonomic revisions in 2019 and 2020, in which two former subspecies were elevated to separate species. As a result, the Raffles' banded langur meets the criteria for being listed as critically endangered by the IUCN. It is mainly threatened by habitat loss.
Singapore has a wide variety of flora. Plants are mainly used to beautify the landscape of Singapore. The national flower is a hybrid orchid, Vanda Miss Joaquim.
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.
Bukit Tigapuluh National Park - The Thirty Hills - is a 143,223-hectare National Park in eastern Sumatra, consisting primarily of tropical lowland forest, largely in Riau province, with a smaller part of 33,000 ha in Jambi province. It is famous as one of the last refuges of endangered species such as the Sumatran orangutan, Sumatran tiger, Sumatran elephant, and Asian tapir, as well as many endangered bird species. It forms part of the Tesso Nilo Complex biodiversity hotspot. The Park is inhabited by the indigenous peoples of the Orang Rimba and Talang Mamak tribes.
The National Biodiversity Centre is a branch of the National Parks Board and serves as Singapore's one-stop centre for biodiversity-related information and activities. It manages all available information and data on biodiversity in Singapore. Diverse biodiversity-related information and data are currently generated, stored and updated by different organisations and individuals. The National Biodiversity Centre will maximize the usefulness of such information and data by linking them in a single meta-database. Having complete and up-to-date information is crucial for many decision-making processes involving biodiversity. This hub of biodiversity information and data at the National Biodiversity Centre will also allow knowledge gaps to be better identified and addressed.
