Where lions roam: West African big cats show no preference between national parks, hunting zones

March 30, 2020

West African lions are a critically endangered subpopulation, with an estimated 400 remaining and strong evidence of ongoing declines.

About 90% of these lions live in West Africa’s largest protected area complex, the W-Arly-Pendjari. The WAP Complex includes five national parks and 14 hunting concessions across roughly 10,200 square miles in Burkina Faso, Niger and Benin.

Given that wildlife protection is one of the main purposes of a national park, you might expect West African lions to favor life inside park boundaries, rather than within the privately managed hunting concessions that surround the parks. After all, lions tend to shun people, and human pressures are higher in hunting areas than in the parks.

But a new University of Michigan-led camera survey of West African lions — believed to be the largest wildlife camera survey ever undertaken in West Africa and the first carried out within WAP Complex national parks and hunting concessions — found that West African lions show no statistically significant preference between the parks and trophy-hunting areas.

The findings, scheduled for publication March 30 in the Journal of Applied Ecology, have implications for conservation management of the remaining West African lions.

“Our results suggest habitat quality in national parks is inadequate, leading to a lack of preference in lions despite lower human pressures,” said doctoral student Kirby Mills of U-M’s Applied Wildlife Ecology (AWE) Lab, lead author of the study.

The researchers suspect that the lure of plentiful water, high-quality habitat and abundant prey on hunting properties outweigh the lions’ natural avoidance of humans. Revenues from trophy hunting pay for enhanced infrastructure such as irrigation systems and solar-powered pumps at watering holes, as well as added patrol staff.

At the same time, under-resourced national parks struggle to deal with degraded wildlife habitat, poachers, inadequate staffing and displacement of wildlife by livestock, which are permitted within the parks.

“We recommend prioritizing the reduction of habitat degradation in the parks and increasing water availability to increase suitable habitat for lions and their prey,” said Mills, who conducted the study for her master’s thesis at the U-M School for Environment and Sustainability. “But at the same time, we recognize that management interventions at a large scale require economic resources unavailable to park managers in WAP, an incongruity prolific throughout the range of African lions.”

The study’s senior author is Nyeema Harris, an assistant professor in the U-M Department of Ecology and Evolutionary Biology and director of the AWE Lab. Harris designed the project and led the fieldwork with an international team that included government employees and students from Burkina Faso and Niger.

In the U-M-led study, 238 motion-activated digital cameras were deployed across 5,000 square miles in three WAP Complex national parks and 11 of the hunting concessions. The fieldwork was conducted from February through June in 2016, 2017 and 2018.

Some 1.7 million images were captured during that time, but West African lions triggered the shutter just 96 times, reflecting the critically endangered feline’s scarcity. The cameras were programmed to rapid-fire three to five frames when triggered, so the total number of lion images is 360.

The camera data were used in two types of mathematical models — occupancy models and structural equation models. The occupancy models allowed the researchers to calculate the probability that an animal used a given space, while the SEM models enabled them to disentangle the relative effects of environmental, ecological and anthropogenic factors influencing space use by West African lions.

The researchers found that lion occupancy was largely driven by prey availability, which in turn was shaped by ecological and environmental variables — such as water availability and habitat diversity — that scored higher in hunting concessions than in national parks.

Contrary to the researchers’ expectations, the WAP Complex lions showed no discernable preference between national parks and hunting zones. The U-M-led study provides the first estimate of West African lion occupancy using camera-trap data.

“We hypothesize that ecological cues indicating high-quality habitat, such as plentiful water and available prey, are mitigating the expected avoidance response to the increased human pressures and competitor activity in hunting concessions,” Harris said.

“Because the lions rely heavily on prey, managers may be able to manipulate the distribution of prey within WAP to directly influence spatial distributions of lions and indirectly reduce human-lion conflict.

Stretching across three countries in the West African savanna belt, the WAP Complex is a UNESCO World Heritage site and is described by the U.N. agency as “a refuge for wildlife species that have disappeared elsewhere in West Africa or are highly threatened.”

Trophy hunting is permitted in all of the WAP Complex concessions but is illegal in the five national parks and in Niger’s Tamou game reserve, which is part of the protected area complex. The lions are known to feed on several species of antelope, as well as savanna buffalos and warthogs. Predators that compete with the lions for food include spotted hyenas and leopards.

West African lions are categorized as critically endangered in the International Union for Conservation of Nature’s Red List of Threatened Species. In its 2015 assessment, the IUCN states that the West African lion subpopulation is estimated at just above 400 animals, with fewer than 250 mature individuals.

West African lions are smaller than, and genetically distinct from, other African lions. They form smaller prides, and the males have little to no mane.

“This population continues to decline,” the IUCN assessment states. “Further deterioration of the last protected areas harbouring lions in West Africa will likely lead to the local extinction of the species.”

Leopard versus lioness in Namibia

Leopard Walks Right into a Lion

Watch this incredible moment when an inquisitive & opportunistic lioness sets her eyes on what she decides could be an easy catch.

24-Year-old French biologist and freelance safari guide, Valentin Lavis, was at the perfect spot at just the right time when he caught this rare sighting on video.

He was on an 18-day private safari in Namibia where he and his guests spent the remainder of their trip in the Etosha National Park.

Valentin tells latestsightings.com the story:

“I was guiding an 18-day private safari with 2 clients for a honeymoon. We spent the first 12 days around the country visiting amazing landscapes and a bit of wildlife. My guests were super excited for Etosha National Park and so we spent the remaining 5 nights in the park with a safari every day.”

“We entered the park around midday and made our way to Olifantsrus campsite for the 1st night. We had some great sightings while on safari, but this afternoon was definitely one of the best in my life. It started with an elephant herd crossing in front of us, a tower of giraffes drinking with a honey badger having a mud bath in the middle and at around 5pm I decided to check one last waterhole before heading toward the camp to watch the sunset at the hide.”

“One of the reasons I love this part of Etosha is because it is very quiet and you can often have a sighting just for yourself without being disturbed. There was one vehicle parked next to the water, we started to approach slowly and one of my guests said ‘Lioness!’ Indeed it was! A beautiful lioness was sitting in the open not too far from the water. I soon spotted another animal drinking at the waterhole but it looked way smaller than the lioness… A leopard!!!”

“I quickly positioned the 4×4 to provide a good visual for my guests and waited for the confrontation to happen. It took mere seconds when the lioness started stalking the young female leopard who wasn’t even aware of the lioness’s presence at all! We all tensed up and waited, preparing ourselves for the dramatic but truly wild moment that had to follow, and realized that we are the only few people on earth who will experience this right as it happened.”

“My guests had their cameras ready, and, I too, started to film as steadily as possible while trying to contain my emotions. This was incredibly exciting! The lioness stalked quietly, waiting to get close enough to the leopardess before launching, but as her excitement built up, the leopardess noticed movement and became more than aware of her fate. For a moment, the two stared at each other and the lioness launched as the leopardess turned and speedily ran off into the thicket. After missing her chance, the lioness returned toward the Mopani thickets where she was lying at first. “

“I tried to follow the tracks of the leopardess who disappeared after the attack to try and find where she had run off to, we went toward the main gravel road and my client once again spotted her, she was up in a very uncomfortable thorny bush, completely terrified and alert. We stuck around for an hour or so to see if she would finally calm down and come back down from the tree. Sadly she only came about halfway down the tree when it was time for us to return to camp as the gates were about to close. All bush lovers can confirm: it’s always like this on safari!”
