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.

Recently introduced unmarked spatial capture–recapture (SCR), spatial mark–resight (SMR), and 2-flank spatial partial identity models (SPIMs) extend the domain of SCR to populations or observation systems that do not always allow for individual identity to be determined with certainty. For example, some species do not have natural marks that can reliably produce individual identities from photographs, and some methods of observation produce partial identity samples as is the case with remote cameras that sometimes produce single-flank photographs.

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.

Leopards are the most widely-distributed wild cat on earth. They are found throughout most of sub-Saharan Africa and in smaller populations within the Middle East, southwest Asia, southeast Asia and north to the Amur peninsula of the Russian Far-East. Throughout this distribution, leopards have persisted in hostile areas outside of protected areas due to their secretive nature and adaptable ability to live in a variety of habitats including sub-urban environments.
