Smit E 2024. KAZA elephant survey lacks formal trend analysis.A new report by Elephants Without Borders (EWB), summarising aerial survey results from over a decade across
Southern Africa, found that overall, elephant numbers have not changed significantly.
The report added that while the Kavango-Zambezi Transfrontier Conservation Area (KAZA TFCA) aerial survey counted
227 900 elephants, it lacked any formal trend analysis.
The transboundary aerial survey of KAZA elephants was flown from August to October 2022.
KAZA includes Angola, Botswana, Namibia, Zambia and Zimbabwe, which share international borders along the
Okavango and Zambezi River…

Muller N 2024. South African abalone poaching fuels violence, threatens species.A suspicious vehicle was driving through the streets of Durban, South Africa, around 3:45 a.m.
with water leaking out of the back.
When police pulled over the red Toyota Condor they found eight bags of shelled abalone worth
about R500,000 (just more than $29,100), South African newspaper Daily Maverick reported.
The driver was arrested as it is illegal to harvest abalone without a permit under South African
law.
The mid-January incident is common in South Africa, where abalone poaching is often
controlled by gangs and linked to the devastating spread of crystal methamphetamine and…
Brown CJ, Stander P, Meyer-Rust R, Mayes S 2004. Results of a Crocodile Crocodylus niloticus survey in the river systems of north-east Namibia during August 2004
.This study has provided baseline data on crocodile numbers from aerial and spotlight counts. These data can be used with the results of future counts to determine population trends. The census has also provided information on their distribution of crocodiles in the Kavango and Caprivi regions. And third, it has resulted in the first population estimate for crocodiles in the north-east wetlands of Namibia.

.Areas surveyed: The Okavango River in Namibia, from just northwest the bridge on the Trans-Caprivi highway south to the Botswana border; the entire length of the Kwandu-Linyanti-Lake Liambezi-Chobe system, including the Mamili National Park; and the Zambezi river for its entire length on Namibia's border, including parts of the adjacent East Caprivi floodplains.
Brown CJ, Meyer-Rust R 2004. Winter counts of wetland and floodplain birds in the Kwando River and floodplain system, Caprivi
.Human and, increasingly, elephant pressure on Namibia's wetlands and riparian belts are a major cause of conservation concern. Many wetland birds are listed in Namibia's Red Data Book (Simmons & Brown in prep) because of population declines caused by the degradation and destruction of wetland habitats, and because of high levels of disturbance. Good information on the status of major wetlands and their avifauna is important for their conservation management. Birds provide one of the best indicators of wetland health.

. Biological Conservation
71 87 - 95An assessment of population size is a fundamental stage in the conservation of any species. The recent availability of data from the Southern African Bird Atlas Project (SABAP) provides a tool to investigate the status and distribution of approximately 900 bird species covered by this work. Here, we assess whether or not reporting rate can be used to establish absolute abundance and thereby produce estimates of population size.
