The Great Elephant Census—the largest wildlife survey in history—was an African-wide census designed to provide accurate data about the number and distribution of African elephants by using standardized aerial surveys of hundreds of thousands of square miles or terrain in Africa. [1]

African elephant genus of mammals

African elephants are elephants of the genus Loxodonta. The genus consists of two extant species: the African bush elephant, L. africana, and the smaller African forest elephant, L. cyclotis. Loxodonta is one of two existing genera of the family Elephantidae. Fossil remains of Loxodonta have been found only in Africa, in strata as old as the middle Pliocene. However, sequence analysis of DNA extracted from fossils of the extinct straight-tusked elephant undermines the validity of the genus.

The census was completed and published in the online journal PeerJ on 31 August 2016 [2] at a cost of US$7 million. [3]

History

Scientists believe that prior to European colonization there were as many as 20 million African elephants. By 1979, only 1.3 million elephants remained on the continent. [1]

A pan-African elephant census has not been conducted since the 1970s. The idea of a modern census was devised by Elephants Without Borders and supported, both financially and logistically, by Paul G. Allen. It was also supported by other organizations and individuals, including African Parks, Frankfurt Zoological Society, Wildlife Conservation Society, The Nature Conservancy, IUCN African Elephant Specialist Group, Howard Frederick, Mike Norton-Griffith, Kevin Dunham, Chris Touless, and Curtice Griffin with the report released in September 2016.

Frankfurt Zoological Society voluntary association

Frankfurt Zoological Society (FZS) is an international conservation organisation founded in 1858 with headquarters in Frankfurt am Main, Germany. FZS focuses on maintaining biodiversity and conserving wildlife and ecosystems in protected areas and outstanding wild places. FZS leads and supports about 30 projects in 18 countries. Bernhard Grzimek, renowned German zoo director, zoologist, book author, editor, and animal conservationist in postwar West-Germany, served as president of the Frankfurt Zoological Society for over forty years.

Wildlife Conservation Society Wildlife conservation and zoological organization based in New York, NY

Wildlife Conservation Society (WCS) was founded in 1895 as the New York Zoological Society (NYZS) and currently works to conserve more than two million square miles of wild places around the world. The organization is led by President and CEO Cristián Samper, former Director of the Smithsonian Institution's National Museum of Natural History. Based at the Bronx Zoo, WCS maintains approximately 500 field conservation projects in 65 countries, with 200 PhD scientists on staff. It manages four New York City wildlife parks in addition to the Bronx Zoo: the Central Park Zoo, New York Aquarium, Prospect Park Zoo and Queens Zoo. Together these parks receive 4 million visitors per year. All of the New York City facilities are accredited by the Association of Zoos and Aquariums (AZA).

The Nature Conservancy Organization

The Nature Conservancy (TNC) is a charitable environmental organization, headquartered in Arlington, Virginia, United States.

Mike Chase, the founder of Elephants Without Borders, was the lead scientist of the census. Chase lead a group of 90 scientists and 286 crew in 18 African countries for over two years to collect the data. During this time the team flew a distance of over 500,000 kilometres (310,686 mi), equivalent to flying to the moon and a quarter of the way back, in over 10,000 hours of collecting data. [1] The area covered represents 93% of the elephants known range. [1]

Forest Elephants which live in central and western Africa were excluded from the survey. [1]

The final report was released on 31 August 2016 in Honolulu at the IUCN World Conservation Congress. Data collected showed a 30 percent decline in the population of African savanna elephant in 15 of the 18 countries surveyed. [5] The reduction occurred between 2007 and 2014, representing a loss of approximately 144,000 elephants. [1]

The total population of Africa's savannah elephants is 352,271, far lower than previously estimated. [1]

Three countries with significant elephant population were not surveyed; Namibia which would not release figures and both South Sudan and the Central African Republic where the survey was postponed as a result of armed conflict. [6]

The rate of decline in the population is also accelerating and reached 8% in 2014. [7] The loss of population is primarily a result of poaching with the elephants being killed for their tusks. The ivory is then illegally sold in China and the United States. It is estimated approximately 100 elephants are killed every day for ivory. Loss of habitat is another reason for the drastic reduction in population. [7]

84% of the population was sighted in legally protected areas, and high numbers of carcasses also being found in the same protected areas. [5]

Ivory material derived from the tusks and teeth of animals

Ivory is a hard, white material from the tusks and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, "ivory" can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed. It has been valued since ancient times in art or manufacturing for making a range of items from ivory carvings to false teeth, fans, dominoes and joint tubes. Elephant ivory is the most important source, but ivory from mammoth, walrus, hippopotamus, sperm whale, killer whale, narwhal and wart hog are used as well. Elk also have two ivory teeth, which are believed to be the remnants of tusks from their ancestors.

Poaching illegal taking of wild plants or animals

Poaching has been defined as the illegal hunting or capturing of wild animals, usually associated with land use rights.

African forest elephant species of mammal

The African forest elephant is a forest-dwelling species of elephant found in the Congo Basin. It is the smallest of the three extant species of elephant, but still one of the largest living terrestrial animals. The African forest elephant and the African bush elephant, L. africana, were considered to be one species until genetic studies indicated that they separated an estimated 2–7 million years ago. From an estimated population size of over 2 million prior to the colonization of Africa, the population in 2015 is estimated to be about 100,000 forest elephants, mostly living in the forests of Gabon. Due to a slower birth rate, the forest elephant takes longer to recover from poaching, which caused its population to fall by 65% from 2002 to 2014.

Wildlife of the Central African Republic

Wildlife in the Central African Republic is in the vast natural habitat located between the Congo Basin's rain forests and large savannas, where the human density was smaller than 0.5 per km2 prior to 1850. The forest area of 22.755 million has, considered as one of the richest storehouses of wild life spread over national parks, hunting reserves and community hunting areas, underwent a change over to an alarming situation of loss of wild life due to greed for ivory and bushmeat exploitation by the hunters, mostly Arab slavers from across the borders of the Central African Republic with Chad and Sudan.

Elephant hunting in Chad

Elephant hunting or elephant poaching and exploitation of the ivory trade are illegal in Chad and pose a major threat to elephant populations. The profitable ivory industry is also a threat to the lives of rangers, even in the national parks, such as Zakouma National Park, the worst-affected area.

Destruction of ivory technique used by governments and conservation groups to deter the poaching of elephants

The destruction of ivory is a technique used by governments and conservation groups to deter the poaching of elephants for their tusks and to suppress the illegal ivory trade. As of 2016, more than 263 tonnes (580,000 lb) of ivory has been destroyed, typically by burning or crushing, in these high-profile events in 21 countries around the world. Kenya held the first event in 1989, as well as the largest event in 2016, when a total of 105 tonnes (231,000 lb) of ivory were incinerated.

Species affected by poaching

Species affected by poaching refers both to the effects of illegal hunting and fishing or capturing of wild animals on certain species, and, in a recent usage, the illegal harvesting of wild plant species. The article provides an overview of species currently endangered or impaired by poaching in the Americas, sub-Saharan Africa, and South-East Asia.
