What do you
do when good elephants go bad?
You call-in
the honeybees!
But are we coddling these
elephant criminals?
Maybe.
But there’s a reason for this indulgence.
Elephant
populations in Africa are declining. One
major factor in the decline is habitat loss.
If you’ve lived at all, you know what makes a downward spiral into a
spiral. When things go wrong, we are
often challenged to do more and more . . . with less and less. So are the elephants.
Without a
habitat rich in food, they start going out to eat in places where food is
abundant: farms. Unfortunately, food
produced by human farms is, also, a matter of survival - not just the farmers,
but for their community as well. When a
farmer and elephants confront each other over a farm’s produce, the elephants
often won’t back down. Neither will the
farmers. The elephants know their size
is a big factor in their success in any confrontation. But the farmers have guns. The elephants lose almost every battle.
This was a
tragic situation because both the farmers and elephants were only doing what
they “had” to do. Then, Lucy King, a
researcher for “Save the Elephants,” thought of a solution. What if you could build a fence? But what kind of fence could withstand an
elephant assault? Well, the
effectiveness of King’s fence didn’t depend on the strength of a wall. She knew something about elephants.
Elephants
are afraid of bees. Elephants are really afraid of bees. This sounds like some kind of peculiar
elephant behavior – a kind of animal version of psychological bias -- until you
are introduced to the bees. These are African
bees. In North America, we have African-ized bees. That only means they have some African bee
ancestors. But even these hybrid bees
are called “killer bees” for a reason.
The African bee is really, really mean.
Why are
African honeybees so mean?
Their
touchiness probably has to do with the fierce “honey-robbing” African animals
from which these bees have to protect their hives and honey stores.
African bees are, by the way, only a
different “breed” of the same species of bee you see outside from time to time
– if you live in Europe or North America.
But, like different dog breeds, different bee breeds can make for some
big differences in behavior.
African
honey bees are slightly smaller than their European and North American
counterparts, but the strength of their sting and venom is absolutely identical
to the other members of its species. So,
what makes African bee into killer bees. Only one thing. Their behavior. Like most honeybee breeds, these bees will
leave you alone -- unless they suspect
that you are after their honey. Then,
they will sting first and ask questions later.
They chase down a threat in large, densely packed swarms and sting and
sting and sting . . . like no other bee of their species. A swarm of these bees will chase you, at high
speed, for a third of mile before letting off the chase.
Elephants
have learned, from generations in Africa, that there are some critters that are
so mean (with stings that are so painful), it’s just not worth it to mess with
them.
And, Lucy
King, knew that the elephants knew.
She found out that elephants stay away from acacia trees with African
beehives. And, not only do elephants
never forget, apparently, they gossip about what they remember. When an elephant hears that buzz, they take
off in the opposite direction and tell their “herd-mates” to do the same. Word spreads fast.
King, with
some help, created a “beehive fence.”
Hives hang at 10 meter intervals on a wire that extends entirely around
a farmer’s field.
The hives are
suspended, in the open, where they are visible.
At a height of about 6 feet, a trespassing elephant will bump into a
hive or the wire and all the hives will swing – and out come the buzzing
bees.
Then, the elephants forget about
the meal and beat a path in the opposite direction.
In the end,
this is a win/win result. An often fatal
confrontation is avoided. The elephants
don’t get the meal they wanted or needed, but the farmers aren’t forced to
protect their own food supply by having to kill these large, and generally
friendly, endangered creatures. Confrontations and crop destruction is down by
about 85%.
The six
foot-tall fence, also, allows farmers to harvest the bees’ honey. These hives are fully functional, sheltered
beekeepers’ hives. But, I can hear
someone asking an obvious question. If
African bees are so dangerous and so touchy about their honey, how can anyone
“harvest” honey from one of their hives and . . . er, ah . . . live to tell
about it?
Actually,
Africanized bees are excellent honey producers and have been widely
domesticated by commercial beekeepers in Africa. Why are they the bee of choice in Africa, but
the “killer bee” in America? Well, I
think it has a lot to do with the people in Africa and North America. Africans grow up with African bees -- the only bee they’ve ever known. They are much more careful of bees than the residents
of Northern Europe or the United States.
Africans learn through example and experience how to avoid antagonizing
their sensitive African bees.
On the
other hand, in the southern United States where Africanized bees have become
numerous over the last four decades, we tend to treat these bees the same way
we’ve always treated our bees. Except .
. . our bees were of a much, much more docile nature.
Many North
American beekeepers argue that Africanized bees are good honey producers and
require nothing more than a little different handling than their North American
and Northern European cousins. Some are
even concerned that, at a time when bee populations are declining, we are
“disposing” of Africanized honeybee colonies – treating these as public
hazards.
I can agree
that African bees are probably not so very dangerous for those who have grown
up in a location in which these bees have always been common. Raised in communities that have known no
other bee than the African, even small children pick up proper safety behaviors,
probably by example as much as by any formal instruction from parents.
But we, in North
America, are not conditioned to the Africanized honeybee’s touchy
behavior. Quite the opposite. Every year, deaths and severe injury result
from provocations as simple as walking too close to a tree containing an
Africanized hive. The fear is understandable because the danger,
at least to North Americans and Northern Europeans, is quite real. Beekeepers are restricted in most locations
and prohibited from maintaining Africanized bee colonies because of the danger
to nearby residents.
But our
honeybee security forces are not restricted to rural Africa and can be found in
at least one of America’s largest cities.
Next week, in “Part II,” security guard bees in the Big Apple.
