This archive of reports of wildlife surveys in Namibia aims to:
Public access to information is a vital component of ensuring community engagement in prevalent issues. Wildlife surveys are critical to determine the health of wildlife populations and determine trends over time to guide conservation and management actions.
Wildlife surveys are done for different species using methods that are suited to counting them (e.g. by air or road) in their natural habitats. Such surveys need to be repeated over time to detect long-term trends and inform conservation managers. The Namibian government, non-governmental organisations and private reserves all conduct regular surveys covering different parts of Namibia and targeting different species. This archive will thus serve as a repository of our collective knowledge of the trends and status of a variety of species occurring throughout Namibia.

Knowledge of a population’s abundance is of primary importance for conservation management. However, robust estimates of abundance are often difficult to obtain, especially for cetaceans which spend most of their lives submerged. Cetacean abundance is commonly estimated using aerial or vessel-based line transect surveys and distance sampling methods. During 2012–2014, the first line transect surveys to estimate cetacean abundance were conducted in Namibian waters.

Knowledge of the occurrence and distribution of cetaceans is particularly important for conservation and management, but is still limited within Namibian waters. We collated 3211 cetacean records from the Namibian Exclusive Economic Zone (EEZ) for the period 2008 to 2016 and applied the principle of minimum cross entropy (MinxEnt) to predict habitat suitability. MinxEnt is a generalised form of maximum entropy modelling that allows incorporation of additional information such as sampling bias.

Carnivore populations face threats from increasing human populations and rapidly diminishing, suitable habitat. Large carnivores such as African lions (Panthera leo) commonly attack livestock on lands adjacent to protected areas. This can lead to human-wildlife conflict (HWC) events that result in retaliatory lion killings. Conflict is a primary driver of wild lion population declines which are estimated to have decreased by 43% in the last 20 years.

This report provides summarised results and analysis of the annual game count held on the NamibRand Nature Reserve and the Pro-Namib Conservancy on the 31st of May 2014. This is the tenth consecutive year that the count was held since 2005 and the third year that the farms Springbokvlakte and Saffier have been included. Teamwork was once again the essence of the day as concessionaires, landowners, neighbours and NRNR staff joined in to participate in the event.

This report provides summarised results and analysis of the annual game count held on the NamibRand Nature Reserve and Pro-Namib Conservancy on the 1st of June 2013- for the ninth consecutive year since the count was initiated in 2005. This was also the second year running that the farms Springbokvlakte and Saffier were included in the count since they joined to the reserve in 2012. Teamwork was once again the essence of the day as all concessionaires, landowners, neighbours and NRNR staff joined in to participate in the event.

In 2011, the Ministry of Environment and Tourism conducted a questionnaire to various stakeholders to determine relative abundance of large carnivores throughout Namibia. The results of this questionnaire were quantified and mapped to establish the current range and relative abundance of the six Namibian large carnivores. Recent population estimates for leopards are used here, however, the remaining species we used estimates from the previous Atlas as our best estimates to date.
