Currently the West African populations of lions are Critically Endangered (Henschel et al., 2014) and currently occupy only 1% of their historical range. Yamaguchi, N. and B. Haddane, B. doi:10.1371/journal.pone.0060174. The mane itself is blonde around the face, with the rest of it being a mixture of tawny grey, bright brown, and blackish brown hairs; it becomes darker towards the lion's rear. During the Pleistocene, highly differentiated lion subspecies (or perhaps separate species, opinion is divided) roamed from Spain to Siberia, through the steppes of Beringia, and into the Americas as far south as Mexico. Similarly the Addax has been reintroduced in fenced reserves in Morocco and Tunisia. Considerably larger than modern lions, it was the apex predator of the Pleistocene food web (with perhaps some competition from Homotherium). Pride of cave lions from Chauvet cave. They still persist in Morocco today and would have been an important threat to livestock and, as we know from other regions, also a threat to people. The Barbary lion first became extinct in Tripoli in 1700, then in Tunisia in 1891, Algeria in 1899, and finally, the last known Barbary lion in the wild was killed in the Atlas Mountains in Morocco in 1922. Several zoos around the world claim to have Barbary lions in their collections. Black SA, Fellous A, Yamaguchi N, Roberts DL. The demise of lions from northern regions (above the Sahara) followed a sequence starting in Europe in ancient historical times, central Asia and Egypt and along the North African coast, then a slow shrinkage from the eastern Mediterranean countries. Of course fear of lions (real or imagined) only tells part of the story of concerns by local people in the Rif Mountains in the 1940s. Black, SA, Fellous, A, Yamaguchi, N. and Roberts, DL (2013) Examining the extinction of the Barbary Lion and its implications for felid conservation. Black, SA (2016) “The Challenges and Relevance of Exploring the Genetics of North Africa’s “Barbary Lion” and the Conservation of Putative Descendants in Captivity,” International Journal of Evolutionary Biology, vol. Was it 1955 or 1975?

If a few individuals can be conserved in Ghana, they might provide hope for continuation across the region and for the northern sub-species Panthera leo leo as a whole. Range of lions since the Pleistocene. mammal Review, 41, 3. The authors also advocate against declaring any species as extinct too quickly.

(2013) confirm that the range of lions reached far further south into the Saharan Atlas of Algeria than was ever known, even in the mid 1800s when numbers were higher and lion hunting was common in the region. https://doi.org/10.1007/s10592-017-1039-2, Hedwig D, Kienast I, Bonnet M, Curran B, Courage A, Boesch C, Kühl H, King T (2017) A camera trap assessment of the forest mammal community within the transitional savanna-forest mosaic of the Batéké Plateau National Park, Gabon. In 2006, results of mitochondrial DNA research showed a mtDNA haplotype that is unique to the Barbary lion. The cave walls of Chauvet and Lascaux contain brilliantly realistic images of this extinct animal, showing that it lived in prides, and that males were maneless. Mammal Review, vol. By the early 18th century, lions had disappeared from that region, leaving an isolated population in the Atlas Mountains (modern Morocco, Algeria, and Tunisia). A powerful ruler of the European steppe, the cave lion roamed territories from Spain to the far-off east of Russia. In all likelihood most if not all of these big cats are not real Barbary lions but rather hybrids with lions from sub-Saharan Africa. Biodiversity Journal, 8 (2): 749-752, Barnett, R., Sinding, MH.S., Vieira, F.G. et al. The Egyptians were the first humans to encounter the Barbary lions; Berbers soon followed, forming small villages and farms across the mountains of North Africa some three thousand years ago. Lion sightings since the middle ages across the Maghreb biome (grey shading) of North Africa  (AD1500–1960). Image by Dagmar Hollmann via Wikimedia Commons. Since physical appearance alone cannot ascertain a lion's heritage, the search began for a genetic marker to identify the Barbary lion, using the skeletal remains of Barbaries found in museums around the world. Males and females came together only to breed; their breeding season is thought to have been in January. There are accounts of colonial and local hunters shooting animals outside the state in the late 19th century.

it happened, Barbary lions are without a doubt extinct in the wild, but could they still exist in captivity? Records from captivity show that their gestation was approximately 110 days, after which 1-6 cubs were born, with 3-4 being most common. DOI: 10.1556/AArch.59.2008.2.2, Black SA, Fellous A, Yamaguchi N, Roberts DL (2013) Examining the Extinction of the Barbary Lion and Its Implications for Felid Conservation. In Morocco, the proliferation of firearms during the civil wars and the rise of banditry resulted in the hunting down the last of the Barbary lions. Schnitzler, A.E. Assessment of historical sightings by expert panel reveled the reliability of these sightings is generally high, so varied sources can be sensibly used to map out the story of the species’ decline. In 1872 a professional hunter (Bhil Shikari) associated with a Mr. T. W. Miles brought in the skin of a full-grown Asiatic lioness which he had shot on the Anadra side of Mount Abu, the last met with in Sirohi districts. They have a thick, full tail-tuft. At the time, records suggested that around sixty different lions in captivity might have Barbary ancestry. Here, 400 or so Asian lions eke out an existence, beset on all sides by people and farmland, the last remnants of an empire that once spread from Tunisia via Turkey to the Tigris and beyond. One was shot in the High Atlas Mountains as late as 1942 in the Tizi‐n‐Tichka pass, and a few years before a pair were seen south of the Atlas ranges on the Saharan fringes, with a further group seen in the same area in the mid 1930s. Micropopulations of the animals were identified by Guggisberg (1963) from historical accounts, but these had all disappeared by 1960. The Barbary lion (Panthera leo leo) disappeared from coastal Morocco in regions near the larger human population centres in the 19th century, but survived in remote areas of the High Atlas of Morocco and the Saharan Atlas (north central Algeria) and Aures mountains in northeastern Algeria into the second half of the 20th century. The last known sighting in Algeria was in 1956. The African wild dog no longer inhabits the Sahara desert (and was only present in southern fringes. However there are opportunities for recovery: the scimitar horned oryx is extinct in the wild, but controlled releases in fenced reserves in Tunisia and Chad are looking to re-establish the wild population. This may not be sustainable.

ScienceDaily, 27 February 2009. National Geographic http://voices.nationalgeographic.com/2016/10/11/african-lions-on-the-brink-a-conversation-with-lion-expert-craig-packer/#.V_-y5k2J-to.twitter. They captured and imported thousands of Barbaries to entertain people in Coliseum games over the course of six centuries. Note the lack of manes on the big standing male. 2015). PLoS ONE 8(4):e60174, Guggisberg C.A.W. For example, Black et al. I am extinct in the wild; less than a hundred descendents of the original wild Barbaries still exist, scattered with diluted bloodlines, in the zoos of the world. [Abstract], Conard, N. J.

Only the destruction of habitat along the Mediterranean coast during the French-Algerian War suggests that lions might have disappeared earlier, perhaps by 1958. One notable outcome of this consensus on the presence of lions is that the species is also no longer considered by national legislation in Gabon. 92018)  No longer locally extinct? The few individuals in Mole are a sub population of a tiny population across Senegal, Burkina Faso, Benin, Niger and Nigeria (Henschel et al., 2014), which itself is a tiny population of Panthera leo leo globally (probably less than 2000 animals including in captivity). As a long lived species, this animal has been able to survive persecution, but this single male may be the very last individual from that population. Löwenmensch from Hohlenstein-Stadel. Barbary, or Atlas, lions once roamed throughout the deserts and mountains of northern Africa, ranging from Morocco to Egypt, far to the north of their sub-Saharan relatives. I am a Barbary lion. 8, no. PLoS ONE 8(4): e60174. Leopards were commonly hunted in Morocco well into the 20th century. (2009), ‘Phylogeography of lions (Panthera leo ssp.) Similarly a small leopard population is known to survive in the southern Algerian Sahara, but is lost from 97 percent its historic range. In fact, excavation of the site of Trafalgar square uncovered a number of lion fossils where now their equally impressive bronze cousins lie today.
