Decades after disappearing from Bandhavgarh Tiger Reserve in Madhya Pradesh, the gaur or Indian bison made a comeback following conservation efforts, according to media reports. In 2011-12, a herd of 40 gaur were reintroduced from Kanha Tiger Reserve, and today, Bandhavgarh’s gaur population stands at over 220.
The gaur (Bos gaurus) is the world’s largest wild bovine. Bulls can grow up to two metres in height, and weigh about 1,500 kg — as much as a car! Males have dark, almost black coats, while females are a lighter reddish-brown. Both have upward-curving horns and a shoulder hump, most prominent in adult males.
Despite their size, gaur are shy animals, living in small herds often led by a matriarch. They graze and browse on grasses, bamboo, and leaves, thus dispersing seeds, tilling the soil and maintaining ecosystem balance. They are also prey for animals like tigers, leopards, and the dholes.
Gaur inhabit evergreen and deciduous forests across the Western Ghats and central and northeastern India, and are the state animals of Goa and Bihar. They also occur in Nepal, Bhutan, China and parts of Southeast Asia. Their estimated global population is between 13,000 and 30,000, with about 85% in India.
The International Union for Conservation of Nature (IUCN) Red List of Species categorises the gaur as ‘vulnerable’. In India, it receives the highest legal protection under Schedule I of the Wildlife (Protection) Act, 1972.
Habitat fragmentation and loss, mainly due to agriculture, the spread of invasive species and development, are their main threats. This pushes them towards farmlands and closer to human habitations, increasing risk of conflict. In places like Niligiris and Kodagu, gaurs are adapting by becoming nocturnal to avoid human interactions, whereas in places like Coonoor and Kotagiri, where tea estates offer less cover than coffee plantations, they have overcome their shy nature to coexist with humans all times of the day.
In a story that Mongabay-India published in 2025, T. Ramesh, a senior scientist at the Salim Ali Centre for Ornithology and Natural History, said: “Today, most of grasslands have been taken over by invasive species, leaving little for the gaur to feed on. This forces them to move into interface areas or zones shared by both humans and wildlife, leading to conflicts.”
