The joy of new beginnings…

In the northern hemisphere, the Spring Equinox has brought warmer, brighter days. After this last year, we are all looking forward to more freedom and the joy of new beginnings.

In Africa, record rainfall in many areas has replenished rivers, floodplains and waterholes; wildlife has generally fared well and many camps are rebuilding for the season ahead. Ingenious and impressive conservation work continues and we celebrate some of these in this edition, for now a time for positivity and action.

“ROAARRRR!” I’m down by the river.

Picture the scene: it’s approaching sundown and your game drive is winding back to camp when your guide sees tracks. He carefully manoeuvres the vehicle to reveal an impressive male lion posed perfectly on a grassy mound, his mane a magnificent halo in the ‘golden-hour’ light. Wow!

Dozens of photos later, the lion stretches, shakes his mane, raises his chin to the sky….and roars! Your insides quake; every bone and organ in your body vibrates with the tremors. It is a jaw-dropping sensation, a terrifying reminder of the true power of Africa’s ultimate apex predator.

We have lots of anecdotal information from guides about why lions roar and more recently some scientific research also. We know that lions roar to communicate: to keep in touch with pride or coalition members, to remind rivals of their territory, to call for help and to entice mates. We know that their voices can carry for up to eight kilometres and that other lions can pinpoint their identity and precise location from the call. And now, thanks to newly published research from Oxford University, conservationists can do something very similar.

In partnership with Oxford’s Computer Science department, zoologist Matthew Wijers and his team set out to learn about lions’ voices, habits and potential threats. They made what they call ‘accelerometer biologgers’ – audio recording devices which capture the sound and GPS location of each roar – and deployed these on collared lions in the south-west of Zimbabwe. They conserved battery power by only triggering the recordings when the lions moved their heads and necks to roar, allowing them to gather data for extended periods.

After analysing a mighty 999 roars, each of which could be cross-referenced with precise time, location and climatic conditions, the team made some interesting findings. They found that lions roar most frequently when the temperature is low and humidity high, thus maximising the distance that their calls travel. Equally, they noticed the animals avoided shouting into the wind and only called when air movement was minimal. Unsurprisingly perhaps, roars were made frequently in the early evening and peaked shortly before daybreak. Silence fell when they moved outside their home range or when females were guarding cubs, in a clear strategy to avoid conflict with rivals. By contrast, repeated roaring was most likely to occur when individuals were close to regularly frequented waterholes and rivers.

Perhaps the most interesting conclusion of the research was that lion calls are unique to each individual, much like a fingerprint, and that they can be identified efficiently, even at a distance, with the help of artificial intelligence – which opens the door for easier monitoring of lion populations by conservationists.

Lion populations are declining across Africa. Being able to determine the location and identity of individual lions by sound alone could significantly help conservation of these impressive cats.

Conserving Kafue

Zambia’s national parks have long been praised for their wildlife and scenic diversity, as have the dedicated safari operators who live and breathe conservation in these areas.

Kafue is Zambia’s largest wildlife sanctuary, covering a vast 22,400km2 – an area the size of Wales or Massachusetts. It’s a mosaic landscape of undulating miombo woodland, shallow wetlands known as ‘dambos’, beautiful riparian forest, permanent swampland, sweeping plains and a network of water channels dominated by the broad Kafue River and its idyllic rapids.

This habitat diversity makes Kafue rich in mammals and provides niches for 515 species of birds. There are grazers and browsers aplenty, from secretive sitatunga to sable, diminutive oribi and large herds of red lechwe, as well as elephants and hippos. Predators include widespread lions, relatively relaxed leopards and considerable numbers of crocodiles.

Thanks to Kafue’s sheer size, however, it has been one of Zambia’s harder parks to protect. Now, in wonderful breaking news, the formidable Dutch NGO African Parks together with the Zambian government have announced a joint partnership to further protect and develop the park.

By injecting an initial sum of US$3 million, while a long-term partnership is agreed, African Parks plan to realise the potential of Kafue as a prime tourist destination and raise its profile as an internationally renowned wildlife sanctuary. The NGO has a solid history of securing parks, protecting wildlife and engaging communities across Africa. Having seen their dedication and success in Zambia’s Liuwa Plain National Park and the Bangweulu Wetlands, we are delighted to see the benefits spread to Kafue.

Vulture Culture

Soaring and circling on thermals, vultures are always a useful indicator of a recent kill, but they also play a critical role in cleaning up the bush and maintaining balance in the ecosystem. Devouring the last scraps of a kill at speed, these avian scavengers are highly effective at preventing the spread of bacteria and serious diseases, including rabies, anthrax and cholera, thanks to their thorough carcass-cleaning and powerfully destructive gastric juices.

Vulture numbers are plummeting globally, however and there is concern that in Africa their numbers are dropping to unsustainable levels. In Botswana, which has some of Africa largest contiguous wildlife conservation areas, all five vulture species are officially listed as either Critically Endangered or Endangered on the IUCN red list. The threat of extinction has dire implications for the ecosystems they help manage.

Help is at hand from the team at Raptors Botswana who are working to research and protect these remarkable birds. Last month, in partnership with the Endangered Wildlife Trust and Wilderness Safaris, they fitted satellite tracking devices to six vultures of three species to better understand their use of space. With ever-decreasing ranges from which to forage, fully understanding their movements may prove critical to their survival.

Joining the Spots

Artificial leopard print has long been part of the fashionista’s wardrobe: you can find it adorning shoes, bags, coats, gloves and accessories on almost every high street. But could our love of the exotic pattern help conserve these beautifully attired cats?

Yes, say scientists. In a recently published paper in the Journal for Nature Conservation, Dr Caroline Good and her team from Oxford University’s Wildlife Conservation Research Unit explore the potential of a ‘species royalty’ which would benefit leopard conservation initiatives by exploiting the appeal of their much admired fur coats.

The team’s analysis showed a staggering interest in leopard print fashion: 2.9million Instagram posts tagged with #leopardprint and 80,000 English language news articles in the last 15 years alone. It’s an enduring trend that has sadly not translated into similar concern for the conservation crisis facing leopards: only 2% of news stories mentioning leopard print were linked to the animal’s Vulnerable conservation status.

While this disconnect presents challenges, the researchers see a real opportunity here. In a revolutionary fundraising idea, they propose a species royalty in which a payment is made by fashion brands to spotted cat conservation organisations in exchange for the use of the leopard’s coat patterns. Even the smallest royalty payment on each item would transform funding for spotted cat conservation.

With leopards having disappeared from more than 75% of their historic range already, they need all the help and inventive ideas they can get. As customers, we can demand responsibility from our chosen fashion brands, perhaps by suggesting they consider this scheme.

Meanwhile, we can visit areas where leopards are carefully monitored and protected. The income from tourism in most leopard areas offered by Expert Africa is invaluable to their conservation: check out our top spots for seeing these beautiful cats in the wild.
