Scientific Name: Damaliscus lunatus ssp. superstes Cotterill, 2003
Parent Species:
Common Name(s):
English Bangweulu Tsessebe
Taxonomic Notes: Bangweulu Tsessebe (Damaliscus lunatus superstes) is one of six subspecies of Topi (Damaliscus lunatus), following Duncan (2013). The others being: Topi (D. l. jimela); Tiang (D. l. tiang); Coastal Topi (D. l. topi); Tsessebe (D. l. lunatus); and Korrigum (D. l. korrigum).

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2017
Date Assessed: 2016-08-10
Assessor(s): IUCN SSC Antelope Specialist Group
Reviewer(s): Cooke, R.
Justification:
The current population is estimated in the region of 3,500 individuals and increasing, with animals having been translocated to private land.  The entire population is restricted to the Bangweulu Basin where it remains at risk of poaching and is totally dependent on the maintenance of a favourable hydrological regime.

Geographic Range [top]

Range Description:Bangweulu Tsessebe occur in the Bangweulu Flats of northeastern Zambia and are now extinct in the Katanga Pedicle of DR Congo (Cotterill 2003).

Population [top]

Population:Based on the figures available in Appendix 4 in East (1999), numbers of Bangweulu Tsessebe were in the order of 3,500. Population trends are increasing for the Bangweulu Tseseebe.
Current Population Trend:Increasing
Additional data:
Number of mature individuals:2450
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:An inhabitant of the southern Bangweulu Flats, a large wetland consisting of grass floodplains and swamps. Ranges from shallow grassy plain flooded for only two months to deep, permanent channels. Nearly exclusively grazers, they can go for months without drinking in the dry season if they are feeding on growing grass (Duncan 2013).
Systems:Terrestrial
Generation Length (years):6.1

Use and Trade [top]

Use and Trade: This subspecies is hunted for food and sport. In Zambia the Bangweulu Tsessebe is commonly included in hunt extension packages to the Bangweulu area, along with Black Lechwe (Kobus leche smithemani) and Sitatunga (Tragelaphus spekii). Tsessebe hunted in SW Zambia are Damaliscus lunatus lunatus but there is no distinction made on trophy lists where the fees range from US$1600 to US$3000.

Threats [top]

Major Threat(s): The main threats to Topi in general, including Bangweulu Tsessebe, are agro-pastoral development and overhunting. Bangweulu Tsessebe are totally dependent on the maintenance of a favourable hydrological regime and therefore water abstraction, drought, drainage or dams could rapidly impact upon this subspecies.

Conservation Actions [top]

Conservation Actions: The Bangweulu Tsessebe occurs in Bangweulu, and has been translocated to a number of private game ranches in Zambia (Cotterill 2003). The feasibility of reintroducing Bangweulu Tsessebe into suitable habitat (notably the Kalungu Flats) along the Upper Chambeshi should be evaluated (D. H. M. Cumming pers. comm. in Cotterill 2003).
