The wild water buffalo (Bubalus arnee), also called Asian buffalo, Asiatic buffalo and wild buffalo, is a large bovine native to the Indian subcontinent and Southeast Asia. It was first described in 1792.
The wild water buffalo is the most likely ancestor of the domestic water buffalo. It has been listed as endangered on the IUCN Red List since 1986, as the global population totals less than 4,000 mature individuals.
Assam is a state in northeastern India, south of the eastern Himalayas along the Brahmaputra and Barak River valleys. Assam covers an area of 78,438 km (30,285 sq mi). It is the second largest state in northeastern India by area and the largest in terms of population, with more than 31 million inhabitants. The state is bordered by Bhutan and Arunachal Pradesh to the north; Nagaland and Manipur to the east; Meghalaya, Tripura, Mizoram and Bangladesh to the south; and West Bengal to the west via the Siliguri Corridor, a 22-kilometre-wide (14 mi) strip of land that connects the state to the rest of India. Assamese and Bodo are two of the official languages for the entire state and Meitei (Manipuri) is recognised as an additional official language in three districts of Barak Valley and Hojai district. in Hojai district and for the Barak Valley region, alongside Bengali, which is also an official language in the Barak Valley.
The state has 35 districts with 5 divisions. Guwahati (containing the state capital Dispur) is the largest city in northeastern India. Assam is known for Assam tea and Assam silk. The state was the first site for oil drilling in Asia. Assam is home to the one-horned Indian rhinoceros, along with the wild water buffalo, pygmy hog, tiger and various species of Asiatic birds, and provides one of the last wild habitats for the Asian elephant. The Assamese economy is aided by wildlife tourism to Kaziranga National Park and Manas National Park, which are World Heritage Sites. Dibru-Saikhowa National Park is famed for its feral horses. Sal tree forests are found in the state which, as a result of abundant rainfall, look green all year round. Assam receives more rainfall than most parts of India; this rain feeds the Brahmaputra River, whose tributaries and oxbow lakes provide the region with a distinctive hydro-geomorphic environment.
The water buffalo (Bubalus bubalis), also called domestic water buffalo, Asian water buffalo and Asiatic water buffalo, is a large bovine originating in the Indian subcontinent and Southeast Asia. Today, it is also kept in Italy, the Balkans, Australia, the Americas, and some African countries. Two extant types of water buffalo are recognized, based on morphological and behavioural criteria: the river buffalo of the Indian subcontinent and further west to the Balkans, Egypt, and Italy; and the swamp buffalo from Assam in the west through Southeast Asia to the Yangtze Valley of China in the east.
The wild water buffalo (Bubalus arnee) is most probably the ancestor of the domestic water buffalo. Results of a phylogenetic study indicate that the river-type water buffalo probably originated in western India and was domesticated about 6,300 years ago, whereas the swamp-type originated independently from Mainland Southeast Asia and was domesticated about 3,000 to 7,000 years ago. The river buffalo dispersed west as far as Egypt, the Balkans, and Italy; while swamp buffalo dispersed to the rest of Southeast Asia and up to the Yangtze Valley.
Bubalina is a subtribe of Bovini (wild cattle) that includes the various species of true buffalo. Species include the African buffalo, the anoas, and the wild water buffalo (including the domesticated variant water buffalo). Buffaloes can be found naturally in sub-Saharan Africa, South Asia and Southeast Asia, and domestic and feral populations have been introduced to Europe, the Americas, and Australia. In addition to the living species, bubalinans have an extensive fossil record where remains have been found in much of Afro-Eurasia.
American bison are commonly referred to as "buffalo" but are not members of Bubalina.
The African buffalo (Syncerus caffer) is a large species of true buffalo native to Sub-Saharan Africa, where it is found in a number of disconnected ranges stretching from south-eastern Senegal through West and Central Africa to South Africa. The adult African buffalo's horns are its characteristic feature: they have fused bases that form a continuous bone shield, referred to as a "boss", across the top of the head. The African buffalo is more closely related to Asian buffalo (Bubalus) species than it is to other bovids such as American bison or domestic cattle. Its unpredictable temperament may be part of the reason that the African buffalo has never been domesticated and has no domesticated descendants, unlike the wild yak and wild water buffalo, which are the ancestors of the domestic yak and water buffalo, respectively. Natural predators of adult African buffaloes include lions, African wild dogs, spotted hyenas, and Nile crocodiles. As one of the Big Five game animals, the Cape buffalo (Syncerus caffer caffer), the largest subspecies native to eastern and southern Africas, is a sought-after trophy in hunting.
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. It also hosts the only known population of pygmy hogs in the world. 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.
