The gaur (Bos gaurus), also called the Indian bison, is the largest extant bovine. This species is native to South and Southeast Asia. It has been listed as Vulnerable on the IUCN Red List since 1986. Population decline in parts of its range is likely to be more than 70% during the last three generations. However, population trends are stable in well-protected areas, and are rebuilding in Kaeng Krachan National Park in Thailand.
