Wildlife of Cambodia

Cambodia's biodiversity is largely founded on its seasonal tropical forests, containing some 180 recorded tree species, and riparian ecosystems. There are 212 mammal species, 536 bird species, 240 reptile species, 850 freshwater fish species (Tonle Sap Lake area), and 435 marine fish species recorded by science. Much of this biodiversity is contained around the Tonle Sap Lake and the surrounding biosphere.^[75]

The Tonle Sap Biosphere Reserve is a reserve surrounding the Tonle Sap lake. It encompasses the lake and nine provinces: Kampong Thom, Siem Reap, Battambang, Pursat, Kampong Chhnang, Banteay Meanchey, Pailin, Oddar Meanchey and Preah Vihear. In 1997, it was successfully nominated as a UNESCO Biosphere Reserve.^[76] Other key habitats include the dry forest of Mondolkiri and Ratanakiri provinces and the Cardamom Mountains ecosystem, including Bokor National Park, Botum-Sakor National Park, and the Phnom Aural and Phnom Samkos wildlife sanctuaries.

The Worldwide Fund for Nature recognises six distinct terrestrial ecoregions in Cambodia – the Cardamom Mountains rain forests, Central Indochina dry forest, Southeast Indochina dry evergreen forest, Southern Annamite Range rain forest, Tonle Sap freshwater swamp forest, and Tonle Sap-Mekong peat swamp forest.^[77]

Cambodia is home to a diverse array of wildlife. There have been registered 212 mammal species, 536 bird species, 176 reptile species (including 89 subspecies),^[1] 850 freshwater fish species (Tonlé Sap Lake area), and 435 marine fish species. An unknown amount of species remains to be described by science, especially butterflies and moths (lepidopterans).^[2] Many of the species in the country, including several endemic ones, are recognized by the IUCN or World Conservation Union as threatened, endangered, or critically endangered due to deforestation and habitat destruction, poaching, the illegal wildlife trade, and farming, fishing, and forestry concessions. Intensive poaching may have already driven Cambodia's national animal, the kouprey, to extinction, and wild tigers, Eld's deer, wild water buffaloes and hog deer are at critically low numbers.

Wildlife in Cambodia includes dholes, elephants, deer (sambar, Eld's deer, hog deer and muntjac), wild oxen (banteng and gaur), panthers, bears, and tigers. Cormorants, cranes, ibises, parrots, green peafowl, pheasants, and wild ducks are also found, and species of venomous snakes and constrictors are numerous. Deforestation, mining activities, and unregulated hunting, have diminished the country’s wildlife diversity rapidly.

Cambodia also has many endangered species. Cambodia has 16 globally endangered species and two critically endangered species. Some of Cambodia's endangered species are the Asian elephant, Siamese crocodile, wild water buffalo, and the Germain's silver langur.

Much work is being done in this area to help conserve and protect Cambodia's unique wildlife. Wildlife conservation organizations operating in Cambodia include Conservation International, World Wildlife Fund, the Wildlife Conservation Society, Fauna and Flora International, BirdLife International, Wildlife Alliance, and many others. On 20 December 2016, 163 new animal species were reported in Southeast Asia including one known as the Klingon newt for its resemblance to a klingon from Star trek.
