Now here is a unique conservation idea – working with nature, instead of against it.
It seems that in spite of the fact they are the biggest animals on the continent, African elephants don’t like bees. They go out of their way to avoid them.
Despite their thick hides, adult elephants can be stung around their eyes or up their trunks, while calves who have not developed this thick skin could potentially be killed by a swarm of stinging bees.
Now some clever scientists from Oxford University have come up with a natural way to keep crop-raiding elephants away from human settlements. They made a fence out of beehives.

The fence is constructed of log beehives suspended on poles beneath tiny thatched roofs to keep off the sun. The hives are connected by eight metre lengths of fencing wire. Elephants avoid the hives and will attempt to push through the wire but this causes the hives to swing violently causing the elephants to fear an attack of angry bees.
Results of their pilot study in Kenya show that a farm protected by the beehive fence had 86% fewer crop raids by elephants, and 150% fewer raiding elephants than a control farm without the fence.
The reduction occurred even though none of the hives were occupied, indicating the elephants remember painful past encounters with African honeybees, and avoid any suggestion of them
The beehive fence survives elephant raids, and is cheap enough for the farmers to construct themselves. The reaction from local farmers has been very positive. An additional benefit to the beehive fence is that it affords protection from cattle rustlers.
Once the hives are occupied by native honeybees, the farmers will also get two or three honey harvests a year that they can sell for additional income.
Small farmers in Africa can suffer devastating losses from crop raiding elephants. Animals who are identified as repeat offenders are often shot, so both sides lose.
Now with some clever thought from dedicated scientists, the famers, the elephants, and the honeybees will all benefit. No guns – no poison – no traps. Just a gentle nudge from nature.
