Namibian Wildlife Surveys archive
This archive of reports of wildlife surveys in Namibia aims to:
- provide easy public access to published information and statistics
- enable easy stakeholder access to recent and historical data on wildlife populations
- provide a comprehensive archive of wildlife survey reports in Namibia
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.

Accurately estimating hippopotamus (Hippopotamus amphibius) numbers is difficult due to their aggressive nature, amphibious lifestyle, and habit of diving and surfacing. Traditionally, hippos are counted using aerial surveys and land/boat surveys. We compared estimates of numbers of hippos in a lagoon in the Okavango Delta, counted from land to counts from video taken from a DJI Phantom 4TM drone, testing for effectiveness at three heights (40 m, 80 m, and 120 m) and four times of day (early morning, late morning, early afternoon, and late afternoon).

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.

Modern works on the distribution of Ungulate Mammals in South West Africa are those of Wilhelm (1931), Shortridge (1934) and Bigalke (1958). Older accounts are those of Fischer (1914) and that published by the German Colonial Office in 1913. The purpose of the present study has been to determine the distribution and approximate sizes of the populations of Kudu, Gemsbok, Springbok, Eland, Hartebeest and Hartmann's Mountain Zebra primarily in the farming areas of the Territory, but including also the distribution in the Bantu Reserves within the border of the Police Zone (Fig. 1…
