Wild water buffalo

life science Maturity 5-7 Next article →

The wild water buffalo, known scientifically as *Bubalus arnee*, is a massive bovine native to Southeast Asia and the Indian subcontinent.

This species is highly significant because it is the most likely ancestor of the domestic water buffalo found on farms today. Despite their importance, these animals face a very difficult future. Since 1986, the wild water buffalo has been listed as endangered on the IUCN Red List. Currently, the global population consists of fewer than 4,000 mature individuals.

Understanding the history of this species requires looking back at how scientists classified it. In 1792, Robert Kerr first described the animal using a buffalo skull from Bengal in northern India. He originally proposed the name *Bos arnee*. Later, in 1827, Charles Hamilton Smith introduced the genus name *Bubalus*. Smith identified specific physical traits for these bovids, such as large heads, narrow foreheads, and laterally bent flat horns. While different authors debated whether to call them *Bos*, *Bubalus*, or *Buffelus*, the International Commission on Zoological Nomenclature officially recognized *Bubalus arnee* in 2003.

The physical characteristics of the wild water buffalo are quite striking. They possess ash-gray to black skin and coarse, sparse hair that grows forward from the haunches toward the head. Both males and females grow impressive horns. These horns are heavy at the base and spread widely along their outer edges. In fact, their horns are larger than those of any other living bovid.

These animals are much larger and heavier than their domestic relatives. They can weigh up to 1,200 kilograms, making them among the heaviest wild bovid species in the world. They are only slightly smaller than the gaur.

These buffaloes live in specific types of environments. They prefer wet grasslands, swamps, flood plains, and river valleys that are densely vegetated.

You can find them in countries like India, Nepal, Bhutan, Thailand, and Cambodia. In India, many populations are restricted to protected areas like Kaziranga and Manas National Parks. In Nepal, the population lives in the Koshi Tappu Wildlife Reserve. This population has actually grown from 63 individuals in 1976 to 219 individuals by 2009. To help spread the species, 18 buffaloes were moved from Koshi Tappu to Chitwan National Park in 2016.

The social structure of the wild water buffalo is organized into distinct groups. Adult females and their young form stable clans that can include as many as 30 individuals. These clans are led by old cows, even when bulls are present. Several of these clans may gather together to form a much larger herd of 30 to 500 animals at resting areas.

Adult males live differently. They often form bachelor groups of up to 10 individuals or live as solitary animals. They typically spend the dry season apart from the female clans. Most populations are seasonal breeders, mating in October and November, though some breed year-round.

Diet and survival are closely linked to the buffalo's habitat. They are primarily grazers, meaning they prefer to eat grasses like Bermuda grass and Cyperus sedges. However, they are not picky and will also eat herbs, fruits, bark, and even shrubs. In the past, during the Pleistocene epoch, their diet was much more varied. They used to forage in both forests and grasslands, but today they are mostly restricted to grasslands. They must also watch for predators like tigers, mugger crocodiles, and Asian black bears.

Several serious threats are causing the wild water buffalo population to decline. One major problem is hybridization, which happens when wild buffaloes interbreed with domestic or feral ones. They also face hunting in countries like Thailand, Cambodia, and Myanmar. Habitat loss is another huge issue, as floodplains are being turned into farms or used for hydropower. Additionally, diseases from domestic livestock and competition for food can hurt wild populations. To help, many countries have made the species legally protected. In 2023, for example, four buffaloes were moved to the Udanti-Sitanadi Tiger Reserve to help increase their numbers.
