Summary:Africa’s overall elephant population has seen the worst declines in 25 years, mainly due to poaching over the past ten years — according to IUCN’s African Elephant Status Report.
Africa’s overall elephant population has seen the worst declines in 25 years, mainly due to poaching — according to IUCN’s African Elephant Status Report launched at the 17th meeting of the Conference of the Parties to CITES, taking place in Johannesburg, South Africa.
The report is an authoritative source of knowledge about the numbers and distribution of African elephant populations across their 37 range states in sub-Saharan Africa.
It presents more than 275 new or updated estimates for individual elephant populations across Africa, with over 180 of these arising from systematic surveys. The report summarizes — for the first time in almost a decade — elephant numbers at the continental, regional and national levels, and examines changes in population estimates at the site level.
Based on population estimates from a wide range of sources — including aerial surveys and elephant dung counts — the estimates for 2015 are 93,000 lower than in 2006. However, this figure includes 18,000 from previously uncounted populations. Therefore, the real decline from estimates is considered to be closer to 111,000. The continental total is now thought to be about 415,000 elephants, although there may be an additional 117,000 to 135,000 elephants in areas not systematically surveyed.
The surge in poaching for ivory that began approximately a decade ago — the worst that Africa has experienced since the 1970s and 1980s — has been the main driver of the decline, while habitat loss poses an increasingly serious, long-term threat to the species, according to the report.
“These new numbers reveal the truly alarming plight of the majestic elephant — one of the world’s most intelligent animals and the largest terrestrial mammal alive today,” says IUCN Director General Inger Andersen. “It is shocking but not surprising that poaching has taken such a dramatic toll on this iconic species. This report provides further scientific evidence of the need to scale up efforts to combat poaching. Nevertheless, these efforts must not detract from addressing other major and increasingly devastating threats such as habitat loss.”
With over 70% of the estimated African elephants, Southern Africa has by far the largest number of the species — approximately 293,000 elephants in systematically surveyed areas. Eastern Africa holds about 86,000 (20%) estimated elephants, while Central Africa has about 24,000 estimated elephants (6%). West Africa continues to hold the smallest regional population with approximately 11,000 (under 3%).
Eastern Africa — the region most affected by poaching — has experienced an almost 50% elephant population reduction, largely attributed to an over 60% decline in Tanzania’s elephant population. Although some sites have recorded declines, elephant numbers have been stable or increasing since 2006 in Uganda, Kenya, and Rwanda, and range expansion has been reported in Kenya.
Central Africa’s forest elephant population has been substantially affected by poaching for ivory, since the 1990s. The Democratic Republic of Congo used to hold one of the most significant forest elephant populations in Africa, which has now been reduced to tiny remnants of its former size. Gabon and Congo now hold Africa’s most important forest elephant populations but both have been affected by heavy poaching in recent years, as have the forest and savannah populations of Cameroon. The savanna populations of Chad have taken heavy losses and those in the Central African Republic have almost completely disappeared.
West Africa’s elephant populations are mostly small, fragmented and isolated with 12 populations reported as lost since 2006 in Côte d’Ivoire, Ghana, Guinea Bissau, Sierra Leone, Togo, Guinea and Nigeria. The elephant population in the trans-frontier “WAP” complex that straddles the border between Benin, Burkina Faso and Niger remains the strong-hold of West Africa’s elephant population.
While poaching has not had the same impact in Southern Africa as in other areas, the region is now also facing the emergence of a growing poaching threat. Population declines have been observed in Mozambique and some areas in Zimbabwe, while major populations in Namibia, South Africa and Zimbabwe are stable or increasing, and there is evidence of elephant range expansion in Botswana. There is still uncertainty about the size of the KAZA trans-frontier elephant population — the single largest on the continent — and it remains critical to undertake a coordinated survey of this population.
“This is the first time since 2006 that we have produced an African elephant status report with a continent-wide update and analysis of elephant numbers and distribution,” says Holly Dublin, Chair of the IUCN Species Survival Commission’s African Elephant Specialist Group (AfESG) who led the preparation of the report. “This report highlights how important it is to regularly monitor, assess and analyse the status of the African elephant. Understanding population numbers and their distribution is crucial in order to recognise threats faced by the species, target conservation actions and assess their effectiveness. This has been possible thanks to the IUCN African Elephant Specialist Group’s incredible network of experts and partners.”
Estimates for savanna populations across the continent have improved in both reliability and coverage and many forest populations in Central Africa have been surveyed for the first time.
“This report not only provides information on the changes in elephant numbers but, because it is spatial, it also shows where these changes are occurring,” says first author of the report Chris Thouless, Chair of the AfESG’s Data Review Working Group. “It tracks many elephant populations over time at the site level, allowing us to learn more about why elephant populations are lost or persist in certain areas. This detailed information is essential for understanding what is driving changes in elephant populations.”
The report has been produced by the IUCN Species Survival Commission’s African Elephant Specialist Group, in partnership with Vulcan Inc, a Paul G. Allen company, and Kenya-based charity Save the Elephants. It draws on data from the African Elephant Database of the IUCN African Elephant Specialist Group, which is the most comprehensive spatial database on the status of any wide-ranging mammal species in the wild.
