Damaliscus lunatus ssp. korrigum
|Scientific Name:||Damaliscus lunatus ssp. korrigum (Ogilby, 1837)|
|Taxonomic Notes:||Korrigum (Damaliscus lunatus korrigum) 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); Bangweulu Tsessebe (D. l. superstes); and Tsessebe (D. l. lunatus).|
|Red List Category & Criteria:||Endangered C1 ver 3.1|
|Assessor(s):||IUCN SSC Antelope Specialist Group|
The most recent population estimate puts the total population of Korrigum at 1,850-2,650 animals (ca 1,300-1,850 mature individuals), nearly all entirely confined to in and around protected areas. Recent reports portray continuing declines across the remaining parts of its range and they are estimated to have reached or exceeded 20% over 12 years (two generations).

|Range Description:||Korrigum formerly occurred from southern Mauritania and Senegal to western Chad, but has undergone a dramatic decline since the early 1900s because of displacement by cattle and uncontrolled hunting for meat. The species no longer occurs in Mauritania, Mali, Senegal, or The Gambia, and probably no longer occurs in Nigeria, Togo or western Chad, except as vagrants (Grubb et al. 1998, East 1999). Although believed exterminated in Ghana (East 1999), a relic population was reported recently in NE Ghana (J. Mason pers. comm. in Duncan 2013). Korrigum have shown the largest range reduction of any subspecies of Topi (Duncan 2013).|

|Population:||East (1999) estimated a global population of 3,000 Korrigum. Chardonnet (2004) revised the estimate of the population of Korrigum to 1,850-2,650 (including 800 in W-Arly-Pendjari and 800-1,600 [down from 20,000 in 1962] in Waza National Park (N.P.)). This subspecies has continued to decline across its remaining range, including a large fall in numbers in Waza N.P. (Scholte et al. 2007).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Generally an inhabitant of floodplains and other grasslands in West Africa, Korrigum moved seasonally between the Sahel grasslands, savannas and the floodplains of the inner Niger Delta.|
|Generation Length (years):||6.1|
|Use and Trade:||This subspecies is hunted for food and sport. In Cameroon, the Korrigum has a trophy fee of €3,000.|
|Major Threat(s):||The main threats to Topi in general, and including the subspecies Korrigum, are agro-pastoral development and hunting. The history of the Korrigum exemplifies the fragility of the highly productive Topi species, with declines across all of its range due to overhunting, competition with livestock and loss of habitat (Duncan 2013).|
|Conservation Actions:||Around 98% of remaining Korrigum occur in and around protected areas, primarily in the W-Arly-Pendjari complex (Burkina Faso, Niger, Benin) and in Waza and Benoue in northern Cameroon (Duncan 2013).|
