De-extinction: dinosaur to dodo… or at least to the Barbary lion?

Is the prospect of a lion living wild in the Moroccan landscape just fantasy fiction?

The growth in knowledge of genetic technologies has raised the topic of “De-extinction”, the recovery of extinct species. But is it worth spending money and resources to produce a conservation ‘gimmick’, like a resurrected mammoth? This is a question of ethics; the value of a curiosity. But there are practical implications as well; if we are to reintroduce species into the wild, are we really good enough at reintroductions to make this a success (Donlan 2014)?

De-extinction discussions often relate to famous species such as the Woolly Mammoth, Passenger Pigeon, Dodo and Thylacine and are often criticised for the “Jurassic Park” element of the argument. However one step back from those more spectacular proposals are recently lost sub-species including the Barbary Lion (Jones, 2014) as potential ambassadors or mascots for conservation and biodiversity recovery in their lands of origin. This prospect has been the on-off discussion concerning the fate of the lions of the Kings Collection in Morocco for decades (Nowell and Jackson 1996).

However, the argument for this type of work needs to go deeper. Recovery of such a formidable species into the wild requires a transformation in the landscape and in the thinking of local people, including the conservationists themselves to develop a sensible and worthwhile model of reintroduction. Reintroduction must match biology, socio-economics, local culture and politics – and most of these factors do not involve scientific expertise, but skills and knowledge in quite different aspects of work.

The Northern Lions

Leave a reply

The last micro populations of lions north of the Sahara held out in the North West of Africa (Algeria and Morocco) and in Iraq, Iran and India in the East. Of these, just 400 remain in the Gir Forest with a small number now appear to be established in the Kodinar Coastal strip in southern Gujarat, India.

The last record of lions in Iraq was possibly the two shot by a Turkish governor in 1914 near Mosul and later in 1918 in the lower Tigris . The last Iranian lions had largely dissappeared in the 1940s with sporadic sightings by railway engineers in the years during the second world war. A lion was also thought to have been seen near Quetta in Pakistan in 1935.

In 1963, the last pride of five Persian lions was hunted in the Dasht-i Arzhan districy of Fars Province in Iran. According to Guggisberg, national newspapers and media “celebrated” the killing of these lions with pictures and fanfare. The pride consisted of a female with four cubs in a cave, the male had been shot already. Just as in earlier accounts from Algeria in the 1880s, the female was shot on the spot, and the cubs were taken as trophies. No subsequent sightings have been reported from Iran, although an attempt was made to reintroduce lions into the region in the 1970s, but the animals dissappeared, presumably shot.

Room to move in?

Picture a valley in North Africa, described by Yamaguchi & Haddane (2002):
“…Between the Middle and High Atlas lies a rocky mountainous area where green oaks dominate the landscape…where the endangered Barbary leopard may still survive… Barbary macaques (Macaca sylvanus), Barbary sheep (Ammotragus lervia) and wild boars live there, and Cuvier’s gazelles (Gazella cuvieri) and Barbary red deer (Cervus elaphus barbarus) may also be reintroduced…lions may be released into a securely-fenced semi-natural enclosure…to live with minimum human intervention…, releasing them into an open area is out of question… “

In the North African biosphere, the prey biomass densities are much lower than in the savannahs of Sub-Saharan Africa or the dry forests of western India. The Moroccan Atlas is likely, on average, to be able to support probably less than four lions per 100km². In the Gir Forest in Gujarat, India, where domestic livestock as a supplementary prey base, the carrying capacity of lions is estimated at around 15 lions per 100 km² (Banerjee et al., 2013).

Other comparisons with the higher energy, prey dense and open landscape of the Gujarat (where lions can leave the forest for surrounding human-dominated areas in times of food shortfalls) show how constrained the landscape in North Africa would be:

Gir Forest, Gujarat (1500 km²) – 400 lions
Kodinar coastal forest, Gujarat (60 km²) 12+ lions

Translocation of lions in India has been planned for some time. The planned release site in Kuno Wildlife Sanctuary (an area of 900 km²) would involve reintroduction of only 5-8 animals intially (with plans to move 1-2 adult males every 5 years out of the sanctuary). So, even in a relatively large and currently established wildlife habitat with a reasonably dense prey base, only a very small number of lions would be released.

Additional complications of home range size and number of groups would be a major constraint for any lion reintroduction in North Africa. Would North African animals live in large prides as cmomonly encountered on the African savannah, in family groups, or would a single lioness holds resource territory while male coalitions attempt to maximize female groups within their range, as in India? (Black et al., 2013; Yadvendradev et al, 2009)?

Whilst having wild lions back in North Africa is a big dream for some, it has practical limitations. And then there are the significant needs of local people…

Lion food – try it Tunisian style

Mosaic of lions eating wild boar, 2nd century AD, Museum of El-Jem, El-Jem Thydrus, Tunisia

This 2nd century Roman mosaic from Tunisia is a fine example of its genre and interesting for its depiction of lions, a not unfamiliar scene in artwork of the era.

The picture manages to look both familiar and unfamiliar at the same time. Two lions devouring prey, yet it is two male lions. The prey is relatively large compared to the lions but it is only a pig. The scene is a dry and sparse climate and there are depictions of human presence a temple or palace perhaps… all somewhat fanciful, surely?

Wild boar (Sus scrofa) in India. Photo S Black

There are many pre-Roman artistic depictions of lions devouring prey in Mediterranean art (bulls, deer etc.). Perhaps fewer of lions eating wild boar. We do know that wild boar are the prey of lions in India today and boar would have been prey elsewhere in the former middle eastern range of the species. They would also have been a key prey for lions in North Africa as depicted in the mosaic. If lions were still present in the wilds of Algeria or Morocco today, then wild boar would probably be the best food source (other than domestic flocks).

We know that Barbary lions tended to operate in small family groups rather than the prides familiar in savannah landscapes, so it is interesting to see two males in this depiction – does this offer a clue to how Barbary lions behaved, perhaps?

In reality almost all lion depictions of the classical era show male lions and almost never lionesses, so little can be gained from this depiction. The Tunisian mosaic is most probably a purely artistic interpretation of events. It is satisifying, however, to see the lions depicted with a known wild prey species form the region. In classical European artwork lion prey is more often depicted as domestic cattle, donkeys, horses or wild deer. Interestingly 18th and 19th century art often depicts lions attacking horses and domestic camels.

Old-fashioned human-wildife conflict

There are very few taxidermy specimens of Barbary Lions. Over the past 15 years my colleague, Dr Nobuyuki Yamaguchi has spent months attempting to locate these treasures, following the footsteps of Vratislav Mazak, the famous biologist who had previously tracked down many specimens in the 1960s. Sadly some of these items have gone missing over the past 40 years.

“The thief of Beja” by V. Simeonovski (click image to see full size version)

Only one specimen, in Leiden’s Naturalis Museum in the Netherlands, includes clear information on its provenance. Leading widlife artist Velizar Simeonovski has recreated the scene, showing the male lion being shot at close range (thumbnail link, right) by a local Tunisian defending his livestock. Velizar also offers an interesting commentary on the story.

Th male lion at Beja was shot in 1823, over a hundred years before the last lions dissappeared from the region. Whilst many of the subsequent encounters between people and lions in North Africa include livestock predation by lions it is also true that lions became more adept at withdrawing into remote areas away from human contact. In the 20th century only one third of the 30 encounters with lions resulted in the animal being shot and only two incidents involved livestock attacks.

Lion decline indicates mass extinction

8 Replies

Estimates suggest that today there are around 32,000 to 35,000 lions left. Sixty years ago this figure was somewere between 400,000 and 500,000, so in a lifetime we have seen a decline of 90 percent or more. Over that period the lion population in India (Panthera leo persica) has clung on and grown from just under 200 animals to about 350 – 400 animals today (from a low in the 1890s of about 20 individuals). Even in the 1940s lions were observed as far west as Iran but the entire Middle East no longer is home to these animals. Over this period the North African population has also dissappeared (with the last sightings in the late 1950s).

Worse still, the remaining bulk of population in sub-saharan Africa (see figure below) is patchy and sometimes involves tiny micropopulations, particularly in Central and West Africa, which could easily follow the fate of Middle Eastern and North African populations.

Would a big cat species be able to survive in North Africa today?

Leave a reply

A significant argument against reintroduction of lions into North Africa is that with the combination of deforestation, desertification and impacts on landscapes, plus the continued ingress of human communities, livestock and infrastructure into formerly wild areas, there is little space for a large carnivore in the region.

However the experience with lions in India is that the animals can be quite resourceful in surviving in a region which is relatively heavily populated. In Gujarat, India the human population is 310/km² (800/sq mi). In Algeria this is 16/km², but it should be noted that most of the land area is desert. In Tunisia there is proportionally less desert and the human density is 70/km². In Morocco it is 74/km^2.(World bank).

However larger cats still appear to hang on (just) – indeed the leopard may still survive in the Atlas mountains, although last seen in the late 1990s. A much smaller feline, the serval has been recently spotted in the Atlas for the first time. Most of the other species keep to remote Saharan areas.

In the southern fringes of the region where the Saharan and the Sahel link to sub-saharan Africa, several cat species are present, even if in low numbers. Scat analysis by scientists working in southern Algeria identified continued presence of leopard. Several cheetahs (Acinonyx jubatus hecki) were shot during the early 1990s in southern Morocco and Cuzin (2003) suggested although a few individuals could survive (less than 20), they are most likely extinct. Recent camera trapping in southern Algeria (covering an area of 2,800 square kilometres) the first systematic survey across the central Sahara identified four individual cheetahs.

Lion country: Ain Talawan (Photo: N Yamaguchi)

This landscape is more reminiscent of Scotland than Africa, but is a valley in north-eastern Algeria. Accounts of lions in this region continued up to the early 20th century (Black et al 2013). One of the more memorable regular encounters by local people with lions used to occur in this region.

The stream above the valley runs near a track which was frequently used by local people taking goods to market.

However the stream, although fairly unassuming (see the photo below) was an importnat water point for lions. This meant that people regularly had to drive lions away from the area with sticks when travelling through the area. A colleague in Algeria has collected verbal accounts from an old man who used to travel this route in the 1920s.

The scene is reminiscent of the encounters in the Gir Forest in Gujarat, India which the local Maldhari people experience with the Asiatic lion (Panthera leo persica).

Patterns of lion decline in North Africa

Map of last sitings of barbary lions in 20th Century

The last pockets of habitat where lions were seen in the mid 20th century (1930s – 40s). Well-known populations in central Morocco (Ifrane) and western Algeria (Oran) had already disappeared.

Although there is no definitve survey data for barbary lion presence in North Africa, it is possible to use the information from reported sightings to map the final decline of the species. A quick summary is given in the figure opposite. The mid-grey expanse is the Maghreb ecosystem which was suitable habitat for lions stretching from south-west Morocco through to north-east Tunisia.

The lightest grey patches in central Morocco and north central Algeria indicate where lions had been present up to the 1920s. The darker grey regions indicate where the last micro-populations survived from the 1930s up to the early 1960s (at the latest). The important last populations may well have been completely isolated in North Setif, Biskra and Batna, the Saharan Atlas, southern Morocco on the Saharan fringe, and the southern High Atlas. It is possible that lions traversed the arid zones between the High Atlas, the Saharan fringe and the Saharan Atlas mountains, but the rest of the Algerian populations in the east were probably quite separate after the early 1900s.

Barbary lions: an opportunity for significant zoo-based conservation

The barbary lion is extinct in the wild, most probably since the early 1960s.

Up until that fairly recent time the Sultans of Morocco, followed by the Kings of Morocco after constitutional changes in the 1950s, kept lions in private menageries. These animals had been bred from cubs which were presented as tributes by Berber Tribes of the Atlas Mountains.

In the late 1960s the remaining lions were still in the King of Morocco’s lion garden at the palace of Fez, then later Rabat. After an outbreak of respiratrory disease in the collection in the late 1960s, the lions were then moved to a new purpose built zoo in Rabat in 1973 (Yamaguchi and Haddane, 2002).

The importance of this is that since that first transfer of animals, it has been possible to trace all lions of pure ancestry alive today back to their ancestors – these animals originally in the Moroocan Royal palace collection. This means that zoos holding these descendents have a unique opportunity to keep the bloodline pure, and alive. Efforts by a number of zoos in recent years (Port Lympne, Olomouc, Belfast, Hannover, Madrid) to make breeding transfers and to increase the number of cubs has enabled the population to recover. As recently as 2008 it looked like breeding of these animals was likely to cease and at least one unique bloodline from the original 27 animals moved from the Royal Palace to Rabat zoo was lost at this time when an old non-breeding female in Germany died.

A rejuvinated zoo population with active, well managed transfers of animals between collectiosn will geive enough time for deeper scinetific and genetic analysis to determine the uniqueness and deeper ancestry of these Moroccan animals and their significance to lion conservation.
