[1] An 1822–1824 British expedition across the Sahara to the ancient kingdom of Bornu,[4] returned with single set of horns of an antelope known in the language of that land as a korrigum.
[3] These horns were classified as a new species by William Ogilby in an article in the journal Proceedings of the Zoological Society of London dated 1836, but published in 1837.
[5] Korrigum formerly occurred from southern Mauritania and Senegal to western Chad, but has undergone a dramatic decline since the early 20th century because of displacement by cattle and uncontrolled hunting for meat.
Based no that, the conservation status of the taxon was assessed as 'vulnerable' by the IUCN in 2008, because it was deemed as uncertain whether the species will experience a population decline of 20% in the next two generations (14 years).
[6] In 2016, based on the exact same 2004 information, but using new definitions of assessment statuses which now subtract a significant portion of this National Park population under the assumption that these are not mature adults, the IUCN now claimed the animal was 'endangered'.
