The Elephant Documentary
24 July 2013
Elephants are large mammals of the family Elephantidae and the order Proboscidea. Traditionally, two species are recognised, the African elephant (Loxodonta africana) and the Asian elephant (Elephas maximus), although some evidence suggests that African bush elephants and African forest elephants are separate species (L. africana and L. cyclotis respectively). Elephants are scattered throughout sub-Saharan Africa, and South and Southeast Asia. They are the only surviving proboscideans; extinct species include mammoths and mastodons. The largest living terrestrial animals, male African elephants can reach a height of 4 m (13 ft) and weigh 7,000 kg (15,000 lb). These animals have several distinctive features, including a long proboscis or trunk used for many purposes, particularly for grasping objects. Their incisors grow into tusks, which serve as tools for moving objects and digging and as weapons for fighting. The elephant’s large ear flaps help to control the temperature of its body. African elephants have larger ears and concave backs while Asian elephants have smaller ears and convex or level backs.
Elephants are herbivorous and can be found in different habitats including savannahs, forests, deserts and marshes. They prefer to stay near water. They are considered to be keystone species due to their impact on their environments. Other animals tend to keep their distance, and predators such as lions, tigers, hyenas and wild dogs usually target only the young elephants (or “calves”).
Females (“cows”) tend to live in family groups, which can consist of one female with her calves or several related females with offspring. The latter are led by the oldest cow, known as the matriarch. Elephants have a fission-fusion society in which multiple family groups come together to socialise. Males (“bulls”) leave their family groups when they reach puberty, and may live alone or with other males. Adult bulls mostly interact with family groups when looking for a mate and enter a state of increased testosterone and aggression known as musth, which helps them gain dominance and reproductive success. Calves are the centre of attention in their family groups and rely on their mothers for as long as three years. Elephants can live up to 70 years in the wild. They communicate by touch, sight, and sound; elephants use infrasound, and seismic communication over long distances. Elephant intelligence has been compared with that of primates and cetaceans. They appear to have self-awareness and show empathy for dying or dead individuals of their kind.
African elephants are listed as vulnerable by the International Union for Conservation of Nature (IUCN), while the Asian elephant is classed as endangered. One of the biggest threats to elephant populations is the ivory trade, as the animals are poached for their ivory tusks. Other threats to wild elephants include habitat destruction and conflicts with local people. Elephants are used as working animals in Asia. In the past they were used in war; today, they are often put on display in zoos and circuses. Elephants are highly recognisable and have been featured in art, folklore, religion, literature and popular culture.

Elephant births at Zakouma National Park in Chad represent a big win against the poachers
January 2014: The birth of 21 elephant calves at Zakouma National Park in the Republic of Chad, one of the last strongholds for migratory herds of savannah elephants in the central African region, has been welcomed as a turnaround in the fortunes of the park’s beleaguered elephant herds.
Poaching had reduced the Park’s elephant population from 4,000 to 450 between 2006 and 2010, leaving the traumatised herd too stressed to breed. Although African Parks stabilised the population after it took over the management of Zakouma in 2010, only five calves were born between 2010 and 2013.
Rian Labuschagne, Zakouma’s Park Manager, said that a lion study they carried out around 2005 found that elephant calves made up 23 per cent of the big cats’ diet at that time. “It was a direct result of the then rampant poaching that left substantial numbers of calves orphaned and easy prey for the lions,” he said.
The flush of elephant calves sighted by Labuschagne and his team shortly before Christmas now changes the status of Zakouma’s elephant population from “stable” to a “definite increase in numbers” and is testimony to the success of the intensive anti-poaching strategy implemented from late 2010 by African Parks, a non-profit organisation that takes on total responsibility for the rehabilitation and long-term management of national parks in partnership with governments and local communities.
Anti-poaching measures have included the year-round deployment of patrols and specialised anti-poaching technology in the extended elephant range, aerial support for patrols, the fitting of satellite collars to individual elephants and establishing a park-wide radio communication system. They have also implemented increased intelligence-gathering and a reward system for information. As a result, there has been no poaching of elephants in Zakouma for more than two years.
Labuschagne concluded: “We are thrilled that Zakouma’s elephant numbers are now growing but are mindful of the continual challenges that we face. At the moment we are implementing major new anti-poaching initiatives to combat ongoing threats that now include the deteriorating situation in the Central African Republic to the south of us.”
