Taxon distribution as listed in assessment
It is native to Bangladesh, Bhutan, Cambodia, China, India, Lao PDR, Malaysia (Peninsular Malaysia), Myanmar, Nepal, Thailand and Viet Nam, and regionally extinct in Sri Lanka (Duckworth et al. 2008). The confirmed presence of two small resident populations of Gaur is in Kassalong RF (forests of Vulongtoli Mon and Betling), Rangamati (Khan 2013, S. Chakma pers. comm.). Moreover, Gaurs are rarely sighted in Sangu WS and few other bordering forests in Bandarban.

Habitat
Habitat details as listed in assessment
Gaur occurs mainly in evergreen, mixed evergreen and moist deciduous forests, but also occurs in dry deciduous forests and forest peripheries. It is nocturnal but also diurnal in undisturbed areas. It lives in groups of few to nearly 50 Gaurs. Gaur is basically a grazer but would browse on bamboo leaves, reeds and shrubs. It depends on water for drinking, but does not normally bathe or wallow. Males make mating call during the mating season (Asmat 2009, Duckworth et al. 2008).

Assessment rationale/justification
The Gaur used to be considered as an extinct species in Bangladesh (IUCN 2000), but few years ago the confirmed presence of two small resident populations in Kassalong RF (forests of Vulongtoli Mon and Betling), Rangamati, was reported (Khan 2013, S. Chakma pers. comm.). Moreover, Gaurs are rarely sighted in Sangu WS and few other bordering forests in Bandarban, but it is not yet sure whether they represent any resident population or vagrant individuals (Khan 2013).
