Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Cetartiodactyla Bovidae

Scientific Name: Kobus kob ssp. thomasi
Species Authority: (P.L. Sclater, 1896)
Parent Species:
See Kobus kob
Common Name(s):
English Uganda Kob
Taxonomic Notes: Lorenzen et al. (2007) question the taxonomic status of K. k. kob and K. k. thomasi as two separate subspecies due to the similarity of their mtDNA sequences (although they are phenotypically distinct).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-01-07
Assessor(s): IUCN SSC Antelope Specialist Group
Reviewer(s): Hoffmann, M.
Justification:
Listed as Least Concern as numbers are estimated to be in the tens of thousands, most of them in existing protected areas, and the population trend is generally believed to be stable.
Previously published Red List assessments:

Geographic Range [top]

Range Description:Uganda Kob was formerly distributed from South Sudan west of the Nile, southwards through north-east DR Congo and Uganda, extending into northwest Tanzania, in the grasslands along Lake Victoria, and southwest Kenya (East 1999, Fischer 2013). For map see species account. It disappeared from Kenya in the 1960s and has also disappeared from Tanzania, in both cases due to hunting and expansion of agriculture and settlements (East 1999). Some still occur in South Sudan, notably in Southern NP (Fay et al. 2007). In Uganda it is mainly found in the west and northwest, including in Queen Elizabeth and Murchison Falls NPs, and in DR Congo it occurs in Garamba and Virunga NPs (Fischer 2013).

Population [top]

Population:East (1999) estimated total numbers at 100,000, with 98% in protected areas. There is no updated estimate available. May be reasonably stable in protected areas (Fischer 2013).
Current Population Trend:Unknown
Additional data:
Extreme fluctuations:NoPopulation severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Occurs in open and wooded savanna with access to water, as well as riverine and lake-shore grasslands.
Systems:Terrestrial
Generation Length (years):4.5

Use and Trade [top]

Use and Trade: The sedentary nature of Kobs and their tendency to occur in relatively large concentrations in open areas make them highly susceptible to hunting. This has lead to high levels of unsustainable hunting over most of their range and therefore large-scale declines (Fischer 2013). However under strict protection Kob numbers can recover quickly, allowing sustainable off-takes of about 7% of the population (Mayaka et al. 2004)

Threats [top]

Major Threat(s): Hunting is a major threat, especially outside protected areas, but also within them where protection is not fully effective. Expansion of agriculture and settlements was a contributory cause of their extirpation in Kenya and Tanzania (East 1999).

Conservation Actions [top]

Conservation Actions: Occurs in Southern NP (South Sudan), Queen Elizabeth and Murchison Falls NPs (Uganda) and Garamba and Virunga NPs (DR Congo).
