Scientific Name: Damaliscus lunatus ssp. tiang (Heuglin, 1863)
Parent Species:
Common Name(s):
English Tiang
Taxonomic Notes: Tiang (D. l. tiang) is one of six subspecies of Topi (Damaliscus lunatus), following Duncan (2013). The others being: Topi (D. l. jimela); Bangweulu Tsessebe (D. l. superstes); Coastal Topi (D. l. topi); Tsessebe (D. l. lunatus); and Korrigum (D. l. korrigum).

Population [top]

Population:Aerial surveys carried out by WCS in the early dry season in 2007 indicate a population exceeding 155,000 (probably an underestimate) in the Jonglei area and a generally favourable conservation situation (although numbers in Boma National Park had declined) (Fay et al. 2007). These estimates are lower than those reported for the late dry season in 1980 (by about half; from 350,000 animals), but slightly larger than those recorded in the early dry season in the same year (Mefit-Babtie 1983). Overall the population is approximately stable.
Current Population Trend:Stable
Additional data:
Number of mature individuals:55000-126000
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Generally an inhabitant of floodplains and other grasslands. In Sudan, the Tiang is widespread in savanna and floodplain grasslands, but also occurs in much lower numbers in the woodlands of the south-west. The Jonglei District area of the Sudan is the supreme example of a floodplain population, where animals migrate between the wetlands of the Sudd in the dry season and the woodlands, bushlands and grasslands to the east (Boma N.P.) and the south (Duncan 2013).
Generation Length (years):6.1

Use and Trade [top]

Use and Trade: This subspecies is hunted for food and sport. In Ethiopia, the Tiang trophy fee is between US$400 and US$1100.

Threats [top]

Major Threat(s): The main threats to Topi in general, and including the subspecies Tiang, are agro-pastoral development and overhunting.

Conservation Actions [top]

Conservation Actions: About one-quarter of Tiang occur in protected areas, including: Zakouma N.P. (the largest population in central Africa at ca 1,300) and Salamat Faunal Reserve and Aouk hunting areas (Chad), Manovo-Gounda-St Floris N.P. (CAR), Boma N.P. (South Sudan), Omo N.P. and Mago N.P. (Ethiopia) and Sibiloi N.P. (Kenya) (East 1999, Duncan 2013). There is no information on their status in Dinder N.P. (Sudan), where they may number no more than a few dozen individuals (Chardonnet 2004).
