Kobus ellipsiprymnus ssp. ellipsiprymnus
|Scientific Name:||Kobus ellipsiprymnus ssp. ellipsiprymnus (Ogilbyi, 1833)|
|Taxonomic Notes:||Common Waterbuck (Kobus ellipsiprymnus ellipsiprymnus) is one of two subspecies of Waterbuck recognized (formerly regarded as distinct species); the other being Defassa Waterbuck (K. e. defassa). Lorenzen et al. (2006) found a high degree of genetic differentiation between the subspecies and strongly confirmed hybridization in Kenya’s Nairobi N.P. population.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Antelope Specialist Group|
Listed as Least Concern as numbers are estimated at 105,000, with more than 50% in protected areas and 13% on private land, and there is no evidence that the subspecies approaches the thresholds necessary for listing as Near Threatened or Vulnerable.
|Previously published Red List assessments:|
|Range Description:||Common Waterbuck (Kobus ellipsiprymnus ellipsiprymnus) broadly occurs east of the Eastern Rift Valley, extending southwards to about the Hluhluwe-Umfolozi N.P. in KwaZulu-Natal and central Namibia (Spinage 2013). Common Waterbuck are extinct in Ethiopia, though Defassa Waterbuck remain (Spinage 2013).|

|Population:||East (1999) produced a global population of approximately 105,000 Common Waterbuck (a conservative corrected continent-wide estimate based mainly on aerial surveys). No recent global population estimate is available. Overall population trend is decreasing.|
Typical density estimates obtained by aerial surveys of areas where the species is reasonably common are of the order 0.05-0.15/km². Ground surveys have provided density estimates of the order 0.4-1.5/km² in areas where the species is common.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Inhabits savanna woodlands and forest-savanna mosaics near permanent water (East 1999). Common Waterbuck persist in drier regimes than the Defassa Waterbuck (Spinage 2013). Waterbuck are able to exploit a range of habitats to which its congeners are specifically adapted, albeit only to a varying degree, being not as aquatic as the Lechwe, nor as independent of water as the Kob (Spinage 2013). Waterbuck are classified as grazers, but also browse.|
|Generation Length (years):||7.1|
|Use and Trade:||Waterbuck are hunted for food and sport and are particularly susceptible due to their sedentary nature and fondness for cultivation (Spinage 2013).|
|Major Threat(s):||Common Waterbuck have been eliminated widely within their former range mainly due to hunting (Spinage 2013).|
|Conservation Actions:||Over 50% of Common Waterbuck occur in protected areas, plus 13% on private land (East 1999). Important populations of the Common Waterbuck occur in areas such as Tsavo, Laikipia, Kajiado, Lake Nakuru and the coastal rangelands (Kenya), Tarangire and Selous-Mikumi (Tanzania), the Luangwa Valley (Zambia), and Kruger, Hluhluwe-Umfolozi and private land (South Africa) (East 1999).|
