Scientific Name: Damaliscus lunatus ssp. jimela (Matschie, 1892)
Parent Species:
Common Name(s):
English Topi
Taxonomic Notes: Topi (Damaliscus lunatus jimela) is one of six subspecies of Topi (Damaliscus lunatus), following Duncan (2013). The others being: Korrigum (D. l. korrigum); Tiang (D. l. tiang); Coastal Topi (D. l. topi); Bangweulu Tsessebe (D. l. superstes); and Tsessebe (D. l. lunatus).

Assessment Information [top]

Red List Category & Criteria: Vulnerable A4bcd ver 3.1
Year Published: 2017
Date Assessed: 2016-08-02
Assessor(s): IUCN SSC Antelope Specialist Group
Reviewer(s): Cooke, R.
This subspecies has shown a large decline in Tanzania (where the majority of the global population occurs) from around 58,500 individuals in 1999 to 35,000-46,500 individuals in 2014, due to the combined impacts of agro-pastoral development, hunting and the decreasing availability of floodplain habitat. This equates to a projected decline over three generations (18 years) of 25-46% (average decline 36%) in Tanzania. Assuming no decline outside of Tanzania would result in an overall decline of 20-38% (average decline 29%) and a listing of Near Threatened. However we take a precautious approach, noting that any decline outside Tanzania (as suspected) will have pushed the subspecies into a threatened category; therefore it is listed as Vulnerable under criterion A4 (an inferred decline of greater than 30% over three generations: 1999 to 2017).

Population [top]

Population:East (1999) estimated a global population of ca 71,000 Topi. This subspecies is generally decreasing, for example numbers in the Masai Mara declined ca 70% between 1977 and 2007 (Ogutu et al. 2011). The largest population (27,000-38,500) is in the Serengeti ecosystem; there are an estimated 4,000-5,000 in Moyowsi-Kigosi Game reserve and 1,000-2,000 in Ugalla Game Reserve (Foley et al. 2014). In Tanzania (where the majority of the global population occurs) Topi have declined from around 58,500 individuals (East 1999) to 35,000-46,500 individuals (Foley et al. 2014) over 15 years.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:50000-70000
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Topi is generally an inhabitant of floodplains and other grasslands and savannas in East Africa. Nearly exclusively grazers, they can go for months without drinking in the dry season if they are feeding on growing grass (Duncan 2013).
Generation Length (years):6.1

Use and Trade [top]

Use and Trade: This subspecies is hunted for food and sport. In Tanzania, the Government trophy fee for a topi is US$800, so with added Community Development/anti-poaching fees, the full trophy fee is between US$950 and US$1900.

Threats [top]

Major Threat(s): The main threats to the species in general, and the subspecies Topi (D. l. jimela), are agro-pastoral development and hunting. The maintenance of floodplains is also important, for example the population around Lake Rukwa (Tanzania) decreased following a rise in water levels which caused a reduction in the area of the floodplain (Vesey-Fitzgerald 1960, Rodgers 1982).

Conservation Actions [top]

Conservation Actions: More than 90% of Topi occur in protected areas, in particular Serengeti N.P. (Tanzania), Queen Elizabeth N.P. (Uganda), Virunga N.P. (DR Congo), Akagera N.P. (Rwanda) and Maasai-Mara (Kenya). However, the populations in Queen Elizabeth N.P and the Virungas have been declining (East 1999). The population in Akagera, the last effective stronghold for Topi in Rwanda, declined from around 7,500 in 1990 to an estimated 770 in the late 1990s following the reduction in size of the park in 1997 (Williams and Ntayombya 1999), although the population has since recovered (Apio and Wronski 2011).
