What to do when vervet monkeys become a nuisance.
(Original by The Vervet
Monkey Foundation)
The
Vervet monkey is an "Old World Monkey" primate species indigenous to South
Africa. They are also a close relative of ours, and therefore, highly
intelligent and adaptable. They live in complex social structures, known as
troops, and are very similar to tribal societies with an alpha male (chief)
as leader. Vervets use an elaborate verbal system of communication that
incorporates an extensive vocabulary, body language, and facial expressions.
Even though man has always been fascinated with these monkeys, very little
is known about them and their role in nature is only now becoming
acknowledged and appreciated. The reason why so little is known about this
wonderful primate is due to its previous classification as "VERMIN". As a
result, no interest was shown towards them and consequently the available
information about this primate is very inaccurate, incomplete and
prejudiced.
Even though humans display a great fascination and love for monkey primates,
Vervet monkeys are still persecuted and killed indiscriminately. It is
therefore, the intention of this booklet to inform people of the true nature
of these wonderful creatures and most importantly, the role that they play
in nature. It also explains why they lose their inherent fear of man and
begin to interact with people.
BACKGROUND
Unlike most wild animals, Vervets have the ability to climb and jump over
fences and most other obstacles. Therefore, they are not easily contained,
especially since they cannot be fenced in with traditional fencing. Over a
period of many years, and as their habitats began to diminish, troops of
Vervet monkeys became more and more exposed to their human cousins, man. To
compound the problem, these monkey creatures fascinate humans and as soon as
contact is made with them, we begin to befriend them by offering a variety
of delicious and interesting things for them to eat. After many years of
this interaction, monkeys lose their inherent fear of people and begin to
interact with us. Consequently, people living next to or in natural areas
start to experience more and more incidents with monkeys.
We must also understand that not all people complain when Vervet monkeys
come onto their property, indeed they encourage them, welcoming their visits
and openly feed them. (Studies show that people, who befriend monkeys, are
not happy until they get the monkey to come right up to them and take the
offered food right out of their hands. There are cases where people invite
monkeys to join them at a table where they would have "tea with the
monkeys".)
It has been established that the people who make the original contact with
Vervet monkeys are not always the ones who end up with problems. What
frequently occurs is that new residents arrive, also become fascinated by
the monkeys and befriend them. These monkeys become braver and more
familiar, often gaining access to inside the household and generally cause
havoc. Now, feelings of resentment are built up by these humans and they
advocate the killing, removal or relocation of the monkeys who are in fact
the original residents of the area.
The Hamptons Wildlife Care Centre is well aware of this conflict between
people and Vervets, and we endeavour, through education and encouraging
co-operation from the public to learn to live with Vervets. Problems
experienced with Vervets can be corrected without killing, re-locating or
eradicating them.
WHY MUST WE LIVE WITH THEM?
We must begin to learn to live with monkeys, because they play a very
valuable role in nature and many of the plant and animal species owe their
existence to, and, depend on Vervet monkeys.
Here are just a few examples. It has been ascertained that many plants are
not only reliant on monkeys to spread their seed but such seed must actually
pass through the monkey's digestive system before they can germinate.
Indeed, studies carried out in the rehabilitation of the dune mining in the
Richards Bay area proved that monkeys have the ability to replant areas and
rehabilitate them NATURALLY, by defecating seed in open areas of their
forest. Therefore, it is obvious that when any troop of monkeys is
eradicated the entire ecological environment suffers and the affected area
becomes deforested and loses natural plant life.
Vervet monkeys are diverse eaters; this means that they eat a variety of
foods which can be broken down into: fruit, berries, leaves, flowers,
pollen, nectar, lichens, gum, bark, shoots, roots, grasses, seeds, insects
in all phases, and bird eggs. Because of this varied eating habit they play
a valuable role in pollination as they visit trees that are flowering and
while foraging in them for nectar, their coats become impregnated with
pollen, which is then brushed onto receptive stigmas. Vervets also groom
other mammals like small buck and duikers and this action removes parasites
and employs a valuable role in preventing disease. Vervets also control
insect populations, as they eat all stages of insects from eggs to adults.
Their insect controlling abilities however, is best illustrated by their
love for insect eggs, thus preventing the emergence of adult insects.
Another factor that we must consider is the uniqueness of these remaining
troops of Vervets. Firstly they are probably the only ones left in the area
and have become trapped in pockets of natural habitat for them to live in.
Secondly, if you had to trace the origin of the troop you will find that it
is the remains of an ancient troop that has been around for millions of
years and used to be ninety to a hundred and twenty members strong. Culling,
trapping exercises, road kills, poisonings and indiscriminate shooting of
them has resulted in these smaller troops.
SOLVING THE PROBLEM!
From the above it can be determined that humans caused this problem and we
have to take responsibility for reversing it. Just as it took a long time
for the monkeys to lose their inherent fear of man so it takes time to
recondition them to stop interacting with us. Instead of eradicating or
re-locating them, the Community can work together to solve the problem.
Here are the DO'S and the DO NOTS that we must all follow. The most
important thing is to stop feeding them, so the first do not is:
-
DO NOT FEED THE MONKEYS. Here signboards must be erected and the
community becomes the wardens who must politely stop any person whom
they see feeding a monkey.
-
DO NOT LEAVE FOOD LYING AROUND or unattended, this includes pet
food. Rather put your pet's food in an area that is not accessible to
monkeys or, feed your pet at night when the Vervets are asleep. Rubbish
bins must be tightly closed and where monkeys have learned how to open
them, they must be secured in a more efficient manner. Simple strips of
inner tube can be cut and looped around the lid and handle, making it
impossible for a monkey to get at the contents.
-
DO NOT ENCOURAGE CHILDREN to eat in front of monkeys.
-
Be very firm, DO NOT encourage, or allow monkeys onto your
property the one-day, then chase them away the next. This confuses them
and may make them aggressive.
-
DO educate your children in the DO's and DO NOTS.
-
DO form action groups and get the community involved.
In extreme cases we recommend the use of catapults to chase them away, we
endorse the use of pieces of potato cut into suitable sizes, big enough to
show them that you mean business. If you ever manage to score a direct hit
with a potato, it cannot cause injury but this will be enough to scare them
away. This method has proved to be very successful at hotels that were
experiencing severe monkey problems. All of the waiters carry catapults and
the monkeys now seldom come close to the hotel or interfere with their
guests. Remember monkeys can be conditioned not to come onto your property.
Monkeys are fun and interesting to watch, but that is all that you must do,
and that's the way to live with them. In South Africa there are communities
that have learned to live with the Vervet monkey, such as in the sleepy
little town of Duiwelskloof nestled in the Low-Veld Mountains of the
Northern Province, where people have been living with Vervet monkeys ever
since the town was established. Today large troops of monkeys can be seen
roaming freely through the town, co-existing with the residents. If they can
do it, then we can do it as well.
If the community feels that they would like to feed monkeys, then the way to
do it is to locate a spot in their natural area where the monkeys are known
to regularly frequent, and is far enough away from people. Here, you leave
the food for them, but remember: never try and feed them by hand. However,
before you do this you should first discuss it with your local Conservation
Department.
If you would like to know more, then please contact the The Hamptons: we
would also like to know of any projects of this nature, as we may be able to
help directly with suggestions on suitable signage, and expert advice.

Interesting fact: The Vervet monkey, like the White Rhino is classified
under appendix II of the CITES convention, (Convention for International
Trade in Endangered Species). This means that it is a species threatened by
extinction. A troop of monkeys is a complex living organism, and has the
means to survive as such; when a troop is eradicated it has no means of
replicating itself and therefore, that troop becomes extinct….
