Analysis of largest elephant surveys ever !
I.Overview
A comparing research between two largest-ever elephant surveys in the Kavango Zambezi Transfrontier
Elephant numbers situation in Botswana and other areas
The uncertainty from conservationists on the disappearance of elephants in the western Angolan
The need of having more research across the transfrontier
IV.Regional wildlife surveys are vital
Regionwide surveys
Invaluable for informing conservation management
Expensive and challenging to complete
Limited data points
Important for surveys to be comparable
Conclusion from two surveys
Several differences between the two surveys
Limiting the comparability of the
two data sets
The lack of certainty in asserting the worrying declines in elephant populations
III. Not quite what it seems
EWB report
A concerning change in elephant population
During Angola civil war (1975-2002)
The death of 100,000 elephants in the conflict
After the war ended
The increasing of elephants population in Angola between 2002-2015
An evidence of a persecuted population
An evidence of a persecuted population
Challenges for conservationists
political reasons
One of the core challenges
Accurating data to inform decisions
Poaching,human-wildlife conflict, habitat loss,drought and the impacts of climate change
II. Analysis
The Kavango Zambezi Transfrontier Conservation Area
A fluid contiguous elephant habitat in 10 years ago
Total area :201,000-square-mile, across Angola, Botswana, Namibia, Zambia and Zimbabwe
established
in 2006
Containing more than half the world’s savanna elephants
Comparing
Elephant population
The EWB analysis
228,000 elephants
A less stable data in a local level
Stable data since 2015 in regional level
The 2022 KAZA Elephant Survey
Botswana, home to more elephants than other countries
Estimated population:132,000
A growth rate of 1.3% since 2015
2018 EWB survey and 2022 KAZA survey
A 25% reduction of elephant numbers in open hunting areas
A 28% rise in elephants numbers in areas where hunting is illegal
Reasons for the size of change
Elephants being killed
The moving trend of elephants
Feeling threatened
Human wildlife conflict and
retaliatory killings
Elephants and hunting
In Botswana
20,000 elephants have been sent to Germany in response to a ban for trophy hunting
carcass ratio
Other areas: an average of 12%
An average of more than 8% in Chobe National Park and Moremi Game Reserve
The 2021 DWNP report
Extrapolating a 6% annual growth rate
figure for the country’s elephant population
Focusing on an estimate of 155,000 elephants from a 2006 survey
Finding no evidence of poaching
Opposite with EWB report( 10/2023-2/2024), 56 carcasses with the tusks removed — evidence of poaching — in one of the areas surveyed
The 2022 KAZA Elephant
Survey
Figure of 131,909 elephants
Consistency with the 2015 Great Elephant Census (130,451) and the 2018 survey figures
