Southern Africa: SummaryThis subregion has the largest elephant population, with almost 53% of the continental DEFINITES + PROBABLES. Almost all of these are derived from systematicsurveys. A large decline in the DEFINITE category of over 46,000 is due to a number of estimates being degraded (mainly from Zimbabwe) and changes in area (mainly fromBotswana). A number of new populations were assessed in Mozambique, Zambia, and South Africa, and a number of Repeat Surveys were undertaken. Major gaps inupdated data exist in Angola and Zimbabwe.

The 2011 PIKE level for Southern Africa was 0.5, indicating that the poaching surge is now impacting even previously secure populations in this subregion. Of particularconcern are MIKE sites in Mozambique, Zambia and Zimbabwe. In Namibia, poaching is increasing in the Caprivi, but so far not impacting Etosha National Park, or KrugerNational Park in South Africa. Again, carcass ratios from recent surveys across the subregion indicate a worrying situation.

The most comprehensive data on elephantpopulation and range worldwide.

While PIKE levels in South Africa remain low, South Africa was identified by the ETIS cluster analysis as a country of concern with regard to large-scale ivory movements. Mozambique is also identified in the analysis as a country of concern, mainly due to its unregulated domestic ivory market and its role as a transit state for ivory flowing toTanzania and directly off the continent. Angola is the only range State in the subregion that has never submitted a single elephant product seizure to ETIS.

A number of transfrontier conservation areas are in place across Southern Africa. The recent Kavango Zambezi Transfrontier Conservation Area (KAZA TFCA) waslaunched in 2012 and provides a framework for conserving this very important area of elephant range. National plans or strategies for elephant management are in place insome range States: Botswana (2003); Namibia (2007); and Zambia (2003).

Human-elephant conflict continues to constitute a long-term threat to elephant conservation. Two countries now have national human-wildlife conflict strategies: Namibia(2009) and Mozambique (2010).

1 IQI: Information Quality Index: This index quantifies overall data quality at the regional level based on the precision of estimates and the proportion of assessed elephantrange (i.e. range for which estimates are available). The IQI ranges from zero (no reliable information) to one (perfect information).

2 PFS: Priority for Future Surveys, ranked from 1 to 5 (highest to lowest). Based on the precision of estimates and the proportion of national range accounted for by the site inquestion, PFS is a measure of the importance and urgency for future population surveys. All areas of unassessed range have a priority of 1. See Introduction for details onhow the PFS is derived.

Note that totals for the Definite, Probable, and Possible categories are derived by pooling the variances of individual estimates, as described athttp://www.elephantdatabase.org/reliability. As a result, totals do not necessarily match the simple sum of the entries within a given category.

South AfricaPopulations in South Africa continue to increase, at least in the largest population in Kruger National Park. Repeat Surveys display an increase of close to 2,500 elephants.

Estimates were available for three New Populations: Mapungubwe National Park, Mjejane Game Reserve, and iSimangoliso Wetland Park (Provincial Reserve). NewGuesses were available for Hluhluwe-imfolozi Game Reserve (Provincial Reserve) and Songimvelo Game Reserve (Provincial Game Reserve).

Repeat Surveys, using the same methodology and coverage, were conducted in Manyeleti Game Reserve, Addo Elephant National Park, Makuya National Park (ProvincialNature Reserve), and Kruger National Park.

Sabi Sands Wildtuin (Private Game Reserve) was surveyed using an aerial total count, but covering a Different Area to the 2006 aerial total count.

Great Fish River Nature Reserve (Provincial Reserve), Mkhuze Game Reserve (Provincial Reserve), Tembe Elephant Park (Provincial Nature Reserve), AtherstoneCollaborative Reserve (Provincial Nature Reserve), Letaba Ranch (Provincial Nature Reserve), Marakele National Park, Mthethomusha Nature Reserve (Provincial NatureReserve), Madikwe Game Reserve (Provincial Reserve), Pilanesberg Game Reserve (Provincial Reserve), Garden Route National Park, and Ithala Game Reserve

(Provincial Reserve) were resurveyed, but using different techniques to the previous counts of those areas. The iSimangoliso Wetland Park (Provincial Reserve) replaced theprevious counts for the Greater St. Lucia Wetland Park (Managed Nature Reserve) and Mkuzi Game Reserve.

A number of private reserves were surveyed and these have been aggregated into one input zone, as requested by the data providers.

There were no new estimates available for the Kariega and Kwandwe Private Game Reserves.
