This is Rastas. He is an African Bush or
Savannah Elephant. He was abandoned as a
baby and was rescued by Wild Horizons
Conservation and Educational Programme in
Victoria Falls, Zimbabwe. This is a wonderful
organization that rescues baby elephants that
have been abandoned or orphaned. Unlike the
sanctuaries in the United States, Wild
Horizons does allow breeding, as they are
focused on the survival of the species. Being an
educational facility as well, school children are
particularly welcomed.

COMPARISONS BETWEEN AFRICAN AND ASIAN ELEPHANTS
The African bush elephant is the largest
living land animal. The adult male, or
bull elephant weighs 6-7 tons and is from
10-11 feet high at the shoulder.
The Asian elephant is smaller than the
African bush elephant. The Asian bull
weighs 3-6 tons and is 8-11 feet high at
the shoulder. The female, or cow is
smaller. The African forest elephant is
even smaller than the Asian elephants.
All elephants grow throughout their entire
lifetime.
Other than size the most noticeable
difference between the African and Asian
elephants is the ears. The ears are used
for social communication and hearing. In
the African elephant, the ears are also
used as a cooling mechanism. The ears of
the African elephants may measure six
feet from top to bottom and are in the
shape of the continent of Africa. The
Asian ears are smaller and are roughly in
the shape of the country of India.

must last them for the rest of their life.
Reproduction and Growth
The elephant cow is pregnant for 18-22 months. Generally only one calf is born.
The African calf is born weighing between 225 and 260 pounds, while the Asian
weighs between 200 and 225 pounds. They are both three feet high at the shoulder.
They become sexually mature between 9 and 14 years. Adult height and weight is
attained at about 25 years. Growth continues throughout their entire life, however
at 25 they begin to grow more slowly. Their life expectancy is up to 60-80 years.

Behavior
All elephants live in matriarchal
(female dominated) societies.
The
oldest cow in the group is most often
the leader. She knows the locations of
food and water, thus the group follows
her.
Elephants are very affectionate. They
are supportive of all members of the
group, especially the young. When
there is danger, they take up a defensive
position to protect the babies.
Elephant Herd at Watering Hole
Volume 1, Issue 1, Revision 1
The bulls stay with the herd until they
are sexually mature at about nine to
fourteen years of age. They may join a
small group of bulls, but they become
more solitary as they age.
Diet
Elephants are herbivo re s
(vegetarians). Asian elephants
are primarily grazers, whereas
African elephants are browsers.
Grazers eat more grass than
browsers who primarily eat
shoots, leaves and twigs of trees,
and shrubs. They eat up to 350
pounds of food per day.

Zoos Vs Some Independent Sanctuaries
There are groups of people who believe that animals should be in their natural habitat in the wild, not in zoos.
With some of these groups it appears that their main focus is on the elephant. They believe that those born in zoos
should be moved to independent sanctuaries. In the United States however, breeding is not permitted in these
sanctuaries. This is partially due to the fact that this would increase the captive population. As there are roughly
only 30,000 Asian elephants in existence in the world, moving all captive elephants to sanctuaries would lead to
the extinction of the species.
Zoos are accredited by the
American Zoo and Aquarium
Association (AZA). Among the
requirements for accreditation
are “to nurture wildlife and
enrich the human experience”.
Zoos are also required to
adhere to the Species Survival
Plan (SSP) which manages the
populations in the zoos. The
AZA inspects all zoos on a
regular basis. This is not the

Elephants being so large are really very lazy animals. The keepers have to entice them to get exercise. In the wild,
they run for food and water which is provided in the zoo.
African elephants are generally not domesticated, but they are endangered. As with Asian elephants, they are not
allowed to breed in sanctuaries.
In 2003 there was a herd of African elephants that were to be culled (killed) in Swaziland due to a lack of food in
their area. There was a group of people who were against them being brought to the San Diego Zoo and Wild
Animal Park; they were in favor of them being killed. As it turns out, the elephants are very happy in their San
Diego home as they are breeding and have had 12 babies. In the 1980s, this same group of people was opposed to
taking the last 27 California condors to a zoo. Their comment was, “Let them die with dignity”. Now there are
over 300 birds flying with dignity in the wild. A few years ago the last California condor brought in from the wild
was returned to Big Sur, his original home.
At the 2012 AZA Annual Conference the Los Angeles Zoo and Botanical Gardens was given the prestigious
Significant Achievement Award. The winning exhibit was the six acre Asian Elephant enclosure with a two and
one half acre barn. The three resident elephants have access to the barn 24 hours a day, and they love their
waterfall and pond.

Today the number in
All elephants are listed as endangered. In Africa, this is primarily due to loss of habitat and poaching (illegal
hunting) for ivory. The desire for ivory began in the seventeenth
century. The poaching of African elephants
accelerated from the mid nineteenth century to the early twentieth century due primarily to the availability of
high powered rifles.
In 1979, the African elephant population was estimated at 1.3 million. One decade later, the number was down
to 609,000 animals showing that more than 50% were poached for their ivory tusks. In Kenya alone, the
elephant population was reduced by 87% between 1970 and 1989.
In 1989, the Convention on International Trade in
Endangered Species of Wild Flora and Fauna (CITES) put a
moratorium on all elephant products. During the next
decade, poaching did decrease not only due to the policing of
the ban but also to the decline in the price of ivory. Illegal
poaching slowed down but was by no means eliminated.

There are excellent substitutes for ivory which
are largely used for piano keys, billiard balls,
brush handles, and some decorative pieces
including jewelry. Ivory carving is a major
industry in Asian countries. Many Asian people
believe that ivory jewelry will protect them from
harm as well as bring them good luck. Religious
jewelry and pieces symbolizing prosperity are
prevalent.
In 2008 China legally bought 73 tons of African
ivory. This has caused a resurgence in illegal
poaching and smuggling. In 2011 alone, 25,000
African elephants were killed for their tusks.
