Botswana seems to be having problems with lions. Or to be more accurate, cattle in Botswana seem to be having problems with Lions.
Ranchers in that area have come up with an innovative way of addressing this problem.

It’s not easy being a cow living among African lions in Botswana. After all, there’s always the threat you could soon be a big cat’s meal. UNSW conservationists have found an effective, low-cost way to protect cattle from their predators and help lions coexist with livestock and farmers.
In a piece of “psychological trickery,” scientists have trialled painting eyes on local cattle butts.
The idea is that the intimidating eyes will trick the lions into thinking they’ve been spotted, causing them to abandon the hunt.
“As protected conservation areas become smaller, lions are increasingly coming into contact with human populations, which are expanding to the boundaries of these protected areas,” says Dr Neil Jordan (https://newsroom.unsw.edu.au/news/science-tech/eye-opening-conservation-strategy-could-save-african-lions), a conservation biologist from UNSW’s Centre for Ecosystem Science.
The lions eat livestock, such as cattle, which negatively impacts the livelihood of the subsistence farmers living in these rural areas. With no non-lethal way to prevent the attacks, the farmers often turn to deadly force, shooting or poisoning the lions in retaliation.

Dr Jordan says these human-animal conflicts have resulted in populations of African lion—a threatened species—“draining away.”
Dr Jordan’s idea of painting eyes onto cattle rumps came about after two lionesses were killed near the village in Botswana where he was based. While watching a lion hunt an impala, he noticed something interesting:
“Lions are ambush hunters, so they creep up on their prey, get close and jump on them unseen. But in this case, the impala noticed the lion. And when the lion realized it had been spotted, it gave up on the hunt,” he says.
A Strategy Derived From Nature

For example, patterns resembling eyes on butterfly wings are known to deter birds. In India, woodcutters in the forest have long worn masks on the back of their heads to ward-off man-eating tigers.
Jordan’s idea was to hijack this mechanism. Last year, he collaborated with the BPCT and a local farmer to trial the innovative strategy, which he’s dubbed “iCow”.
The researchers stamped painted eyes onto one-third of a herd of 62 cattle, and each night counted the returning cows. The effectiveness of the eyes essentially comes down to relative survival rates: are painted cows less likely to be attacked and killed than unpainted cows?
In mid-July, he’ll return to Botswana for three months to further test and validate the tool. He’s raised more than A$8000 on the science crowdfunding platform Experiment.com (https://experiment.com/projects/i-cows-can-intimidating-eye-patterns-painted-onto-cows-reduce-lion-attacks) to purchase 10 cattle GPS loggers, and one GPS radio collar, which will be fitted to a wild lion under anaesthetic.
Dr Jordan’s team, involving a UNSW PhD student and researchers from the BPCT, will paint roughly half the cattle in a herd of 60. They’ll use the GPS devices to monitor the movements of cows and lions, and to determine when and where they meet.
“This will give us information about the exposure of painted and unpainted cows to predation risks, and where the conflict hotspots are,” says Dr Jordan.
If the tool works, it could provide farmers in Botswana–and elsewhere–with a low-cost, sustainable tool to protect their livestock, and a way to keep lions safe from retaliatory killing. That’s good news all around. Lions? :o:o:o
