A Sting Operation to Save Elephants, With No Stings



It’s a well-recognized, dreaded situation in lots of elements of Africa and Asia: An elephant reveals up, wanders into farmers’ fields, and tramples and eats crops. Typically farmers combat again, and elephants are killed.

That sequence of occasions appeared prone to play out not too long ago when a forest elephant bull emerged from the dense jungle surrounding Gbarnjala village in northwestern Liberia.

However this time, issues went otherwise. The munching bull heard an indignant buzzing sound. It froze mid-chew, then turned trunk and high-tailed it out of there.

The bull had heard the sound of a disturbed hive of bees — and like elephants all around the world, it had realized to keep away from the insect sound in any respect prices. However on this case, no bees had been truly current. He had triggered a BuzzBox, an audio know-how that goals to maintain elephants and other people aside.

Video footage of the incident is the primary proof of idea that the packing containers are an efficient deterrent for critically endangered forest elephants, mentioned Tina Vogt, technical director of Elephant Analysis and Conservation, a German nonprofit group that’s testing the units in Liberia.

“We have reports from farmers saying, ‘Oh yeah, it’s really working,’ but now this video is really evidence of that,” Dr. Vogt mentioned.

Battle between people and elephants is an pressing downside throughout Africa. As human populations develop, individuals are encroaching on previously wild areas, together with some recreation reserves and nationwide parks. “Elephants are getting more and more compressed into smaller spaces,” mentioned Lucy King, head of the human-elephant coexistence program at Save the Elephants, which helps to deploy the BuzzBox.

Elephants can take a whole 12 months’s harvest in a single day and infrequently even kill folks they encounter. This breeds worry, anger and intolerance for the animals, eroding neighborhood assist for his or her conservation and typically resulting in retaliation.

“Human-elephant conflict feeds into the issue of local people being recruited into poaching gangs,” mentioned Francesca Mahoney, founder and director of Wild Survivors, a nonprofit based mostly in England that developed the BuzzBox.

Bees are an more and more widespread technique of making an attempt to quell that battle.

San rock artwork from KwaZulu-Natal, South Africa, suggests historic human consciousness of elephants’ worry of bees, Dr. King mentioned. That data was first translated into Western scientific commentary in 2002, when Maasai honey hunters in Kenya talked about to researchers that elephants by no means broken timber that comprise beehives.

Dr. King has been learning elephants’ worry of bees since 2006 and utilized what she realized to create specialised wire fences upon which beehives dangle like pendulums. When elephants disturb the fence, the hives swing and the bees swarm. A examine Dr. King led in 2017 revealed that beehive fences had an 80 % success price in conserving elephants off farms. “Finding a natural threat to scare elephants in the most holistic way possible, without terrifying them or making them go into pain, is really useful for management,” she mentioned.

In some instances, although, hives filled with aggressive African honey bees usually are not ideally suited. “You really don’t want to put live bees in places like school grounds or around water tanks in the middle of a community,” Dr. King mentioned.

The BuzzBox gives the sound of bees with out the accompanying stingers. First developed in 2017 by Wild Survivors’ chairperson, Martyn Griffiths, the most recent mannequin prices simply $100 and is easy sufficient for native faculty kids to construct. The solar-powered packing containers detect transferring objects, which set off audio to play for 30 seconds at a time. The units might be programmed with as much as six tracks of assorted sounds along with bees that elephants don’t get pleasure from, together with barking canines, chain saws, human voices, gunshots or screaming goats. The latest model additionally comprises two high-frequency strobe lights, Ms. Mahoney mentioned, “so it’s a bit of a disco for night-raiding elephants.”

Dr. King careworn that bees and BuzzBoxes wouldn’t resolve the issue of shrinking wild area in Africa, and moderately had been simply two implements in “a whole human-elephant coexistence toolbox.”

However she hopes the Liberia instance will encourage different teams working with forest elephants. “These BuzzBoxes are not only keeping elephants out, but getting communities to ask questions like, ‘Why should we care?’” Dr. King mentioned. “The education opportunity is immense.”
