The elephant was alone and dehydrated when villagers first found her. It was September 2017, and the motherless mammal wandering near Boromo in Burkina Faso was only 2 or 3 months old.

“She was tiny,” said Céline Sissler-Bienvenu, who is currently the senior program officer for European disaster response and risk reduction for the International Fund for Animal Welfare. The elephant must have been discovered within a day or two of separating from her family, Sissler-Bienvenu guesses. “She wouldn’t have survived otherwise.”

Many orphaned elephants don’t make it. But with the help of people in and around Boromo, international conservationists and her best friend, a black-and-white sheep named Whisty, the scrappy elephant is now about 4 years old and thriving. Children at a nearby school named her Nania, or “will”.

Getting Nania from elephant infancy to elephant childhood has meant round-the-clock work for the people involved. And Nania’s rescuers now face a new challenge: figuring out whether she can be returned to life with a wild herd of elephants.

That process has a unique twist for Nania. Just as DNA technology has reunited human orphans with their biological families, similar testing this year revealed that Nania’s mother is probably still roaming nearby, and that one day Nania might join not just any wild elephant herd, but her original family.

The DNA analysis also showed that Nania and her relatives are forest elephants. For those working to save them, this project is about more than just rehabilitating one young forest elephant, but ensuring the future of her species. The International Union for Conservation of Nature recognized forest elephants as their own species, separate from Africa’s larger and more numerous savanna elephants, earlier this year. It also declared them critically endangered.

“Because of the status of these animals in terms of how threatened they are, each individual really matters,” said Ben Okita, a co-chair of the IUCN’s African Elephants Specialist Group, who is based in Nairobi. “Every individual is held dear.”

When orphaned elephant calves are rescued, they are usually found near a mother’s carcass. In Nania’s case, though, no one knew of an adult that had been killed. Although elephant mothers are extremely attentive, Nania’s family left her behind for some reason — perhaps at a night-time river crossing that the tiny elephant couldn’t manage.

The villagers who found her in 2017 sought help from the local wildlife authorities, who brought the elephant to a pen outside their headquarters in Boromo. Locals pooled resources to buy milk for Nania. A drugstore donated powdered infant formula. But the young elephant’s appetite, unlike the funds of the humans around her, was bottomless. The humans needed help.

“They were desperate to know how to handle Nania,” Sissler-Bienvenu said. The wildlife authorities in Boromo, which is a few hours southwest of Ouagadougou, Burkina Faso’s capital, reached out to the International Fund for Animal Welfare for help, and the group took charge of the elephant’s care.

Rehabilitating a single orphaned elephant is a major undertaking. Young calves are dependent on milk for two or three years and need even more time to learn skills and, in certain areas, grow big enough to fend off lions.

“When you start to do elephant rehabilitation, in some places you’re signing on for something that could be 10 or 12 years’ worth of work,” said Katie Moore, deputy vice president for animal rescue at the animal welfare fund.

The organization saw promising signs for Nania, though. She had stayed physically healthy, and she didn’t seem depressed.

“We rapidly decided, yes, we can attack this problem and find a way” to help the elephant return to the wild, Moore said.

Sissler-Bienvenu issued an emergency grant to pay for milk and then flew to Burkina Faso to meet Nania.

She found that the community had rallied around the elephant. Schoolchildren visited her every day, and Nania sometimes chased after them, wanting to play. She got used to the sounds of passing motorcycles and donkeys and shouting people. She sometimes barged into the wildlife authority headquarters to find where her milk was being prepared.

“She became, very quickly, a kind of mascot,” Sissler-Bienvenu said.

But all that human attention wasn’t going to help Nania return to the wild. She needed a home where she could learn to be an elephant.

In February 2019, Nania’s new residence was completed inside Deux Balés, a nearby national park. It included a stable where she would stay at night, and a large fenced pasture called a boma.

Her loyal friend Whisty also lives there, as do four keepers who stay with Nania in pairs, a week at a time. This consistency is important, Moore said. “Keepers really do serve as surrogate mothers and aunties to these young elephants. They comfort them.”

Nania might have a chance to join not just any family of wild elephants, but her own.

Only about 40 wild elephants pass through Deux Balés. The team from the International Fund for Animal Welfare figured that Nania’s family was probably among them. To find out, in 2019 they began collecting samples from heaps of elephant dung. They shipped 17 test tubes to the University of Washington in Seattle in October 2020.

There, Sam Wasser, a conservation biologist, analyzes elephant DNA in his lab. Usually, the samples come from ivory seizures. He and his colleagues sequenced the DNA from little pieces of each tusk to figure out where the poached elephants lived and track the ivory traffickers. It can be heavy work, Wasser said. Using the same tools to potentially help a living elephant reunite with her family “really is a breath of fresh air,” he said.

The lab found a startling result: One of the sampled elephants was not just a relative, but almost definitely Nania’s mother.

“There’s no question that we found the family,” Wasser said.

Sissler-Bienvenu was elated. “We were expecting to have a match with relatives,” she said, but finding Nania’s mother was a dream. The elephant had deposited her dung within about 650 feet of Nania’s enclosure.

And because the DNA analysis showed that Nania and her family are forest elephants, the discovery adds to the potential significance of putting Nania back into the wild.

Moore said that while rescuing an individual animal might represent a huge investment of resources, it could also save a species.

“I can’t imagine not trying,” she said.
