Range DescriptionThe hog badger occurs in Central to Southeast Asia. It is found in Mongolia, India (Sikkim, Terai, Assam, Arunacha Pradesh), throughout southern China, Indochina (Viet Nam, Lao PDR and Cambodia), Myanmar, in Indonesia (Sumatra), throughout Thailand and possibly in Perak, Malaysia (Lekagul and McNeely 1977; Duckworth 1997; Pocock 1941; Holden 2006; Roberton et al. in prep.; Than Zaw et al. in press). There is one isolated record in eastern Mongolia (Aimak Dornod) (Stubbe et al. 1998). According to Holden (2006) in Sumatra the hog badger appears to occur primarily above 2,000 m with one record at 700 m, and historical records also indicate a montane range (Miller 1942). Corbet and Hill's (1992) map suggest that on Sumatra the species is restricted to the southern part of the island, whereas, in fact, individuals have been found in many mountainous locations in the north as well (van Strien 2001).
In Lao PDR, most recent records are from the central part of the country, with some from the north, although historic records come also from the south (Duckworth 1997, Duckworth et al. 1999). There are recent indirect reports (unsubstantiated villager reports) from many survey areas in Lao PDR, but few documented records (R.J. Timmins and J.W. Duckworth pers. comm. 2006); in aggregate, these suggest that this species was present in the recent past, but has more or less been hunted out from quite wide areas (J.W. Duckworth in litt. 2006). Deuve (1972) considered that the species occurred in the southern region of Lao PDR, listing several lowland sites; however, Deuveâs Lao range information is often faulty (e.g. Timmins and Duckworth 1999), so this cannot be taken as complete confirmation the animal was formerly widespread in Lao lowlands. All seven records in 1992-1996 were from in and around the Nam Theun catchment at sites above 500 m (Duckworth 1997), while both historical sites listed by Delacour (1940) are in mountainous areas: Phongsali and the Bolaven Plateau. The post-1996 records are also from hills and mountains (Duckworth et al. 1999).
