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.

In 2022, an aerial survey for African savanna elephants (Loxodonta africana) was conducted over the Kavango-Zambezi Transfrontier Conservation Area (KAZA) in southern Africa. KAZA is a 520,000-km² network of protected areas in Angola, Botswana, Namibia, Zambia, and Zimbabwe. The aerial survey found that KAZA holds ~228,000 elephants, confirming that this is the world’s largest population of savanna elephants and a critical stronghold for this endangered species.
The lions of Namibia's Kunene Region are sought after by tourists, but they are a local threat to livestock farming, and are still largely unresearched in terms of their ecology and ranging behaviour. Though lions in Kunene have been monitored for more than twenty years, it may come as a surprise that the population has not been systematically counted throughout its range - until now. It is less surprising when one realises that the lion range in Kunene covers more than 51,000 km² of mountainous desert landscape.

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.

This survey attempt to quantify the incidence of human-crocodile conflicts (as form of humanwildlife conflicts) in the three perennial rivers namely: Kunene River, Okavango River and the four Zambezi River channels. These are the three river systems in Namibia that are most affected by human-wildlife conflicts. The survey further examine the perspective of local people who use these rivers on HWC, by unpacking the root causes of conflicts and identifying methods to mitigate HWC in the future.
This report presents the results of the third fixed-wing aerial wildlife census of the Caprivi River systems in Namibia conducted during September 2009. The purpose of this survey is to provide recent information on the distribution, abundance and trend of wildlife species including comparisons between protected areas and conservancies. The report compares the results of this survey with earlier fixed-wing aerial surveys conducted in September 2007 and August 2004.
The Okavango River in Namibia, from the Angolan border just northwest of 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 whole Mamili National Park; and the Zambezi River for its entire length on Namibia's border, including parts of the adjacent East Caprivi floodplains, were survey from the air in September 2007.

Aerial surveys of the centra] and eastern areas of the Etosha National Park were undertaken during September 1968, April 1969 and February 1970, primarily to establish the efficacy of an aeroplane in counting the larger mammals in the Park and to obtain some idea of the numbers and distribution of the various populations. Previous census methods such as road strip counts and waterhole counts were found inaccurate, unreliable and often impractical in Etosha.
