In
the commercial sector, which basically
covers the farming community, is where
most vervet monkeys start their journey
into human hands and end up in rehabilitation
centres, all due to a mis-conception
that they destroy crops. In this section
we will try to explain why they don't,
and why farmers should encourage vervets
to visit there orchards.

Protecting wildlife
Vervet monkeys, like humans,
enjoy a variety of foods including
insects, leaves, flowers, fruit,
moulds, scale, fungus and eggs
which all form a part of a vervets
diet. Most orchards offer this
variety in abundance and is therefore
the main reason the vervets are
there.
The accusation of damage, although
unfounded, probably came more
from the farmer seeing monkeys
as wasteful. When times are hard
and prices are low, seeing someone
take a bite out of your fruit
and throw it on the ground can
be seen as damaging but probably
more to your spirit than the actual
crop. The reason they don't destroy
crops will be outlined below.
Are
vervets causing the damage?
Vervet monkeys will tend not
to eat the peels and skins of
fruits. A tell tale sign that
a vervet monkey has eaten your
fruit is bite size pieces of
skins, husks and pips of the
fruit littering the ground below
the tree. How to minimize this
damage? Read on below...
Is
the destroyed fruit ripe? If
it is, then it could indeed
be a vervet monkey. If not ripe,
then a vervet monkey is probably
not to blame. Monitor who is
infact eating the crop.
Are
your crops being eaten during
the night or day? Vervets normally do
not feed at night and are most
often spotted foraging for food
during the day. If it is indeed
nocturnal animals damaging your
crops, research possible ways
of protecting them - an alternative
to shooting is always available.
We can offer advice on protection
methods.
Minimize
damage.
Set up a vervet feeding area
on the edge of your fields where
the monkeys can enjoy some old
or infested ripened fruit, directing
them away from any crops you
would like to protect. Determine
where the monkeys are sleeping
at night and place the feeding
area between their sleeping
trees and your fields.
Reasons why vervets dont
cause damage in commercial orchards:
Most of the commercial crop plants
are picked while still green and
artificially ripened, this goes
for mango, avocado and banana. Macadamia
nuts are too hard for Vervet Monkeys
to bite through.
Evidence of damage was reported
in mango. Just to clarify the damage,
an occasional fruit was found in
the orchards that had a vervet bite
mark and the fruit was still green,
giving rise to the accusation that
they where testing for ripe fruit.
What came out of this investigation
was that the fruit had either sun
damage or was stung by fruit fly
causing a ripe spot, of which the
vervet would bite out removing the
fruit fly aswell.
Litchie are probably the only crop
that could put claim to a certain
amount of damage. However, considering
the short picking period a guard
could be employed to chase the monkeys
away. A note on this is that the
damage can't even be measured in
a percentage so whether or not it
is justifiable to call it damage
is another question entirely. Another
consideration is that due to their
size and vervets liking variety,
they can only eat so much of a certain
item and not for very long.
A good example is to compare them
to yourself, how many mangoes, bananas
or litchies for that matter could
you eat in one go? and for how many
days in a row could you do that?
Now look at a vervet monkey who
is probably not even a 10th of our
size, its just not physically possible
for them to consume enough to even
warrant calling it damage.
Why
are vervets good for my orchards?
Certain crops are wind pollinated
and with the vervet jumping through
the trees it causes pollen to
be released and shaken into the
air. They also help with selective
pruning and picking, as they jump
through the branches, the dead
ones are broken off and any fruit
that is set poorly also falls
to the ground, causing the tree's
energy to be directed to the healthy
ones. Vervets also like scale
and various insects so they keep
these under control for the farmer.
Vervets play a vital roll in
seed dispersal and are a very
intricate part of the cycle that
a lot of indigenous trees need
to follow to germinate. They also
help a lot of the smaller animals
come across fruit and berries
as they knock them out of trees
and should probably be looked
at as the gardeners of our indigenous
trees and plants.
