Accurate information about animal populations is desirable for conservation and sustainability in long term resource mitigation in almost every ecological investigation. Estimating the population density is a complicated process, that requires proper planning and using correct tools. This thesis examines the applications of Unmanned Aerial Systems technology to animal counting, taking from the experience of numerous field experts and researchers. As a result, a set of guidelines was developed in order to aid with the preparation required before conducting an animal biodiversity survey in an arid savanna region using UAS. The set of guidelines consists of 11 factors, with their properties explained in detail.To validate the guidelines in the field, the research team conducted a survey of a single block property located in Namibia. Some of the factors were optimized for the Semi-Arid environment and external environmental conditions of the region. The configuration of the UAV, the software and factors are discussed in the results section of the thesis.The data collected during the survey process was analyzed by a team of students. The animals in the images were detected, divided into species and saved in database, which was later a subject of statistical analysis used to assess the precision and repeatability of aerial surveying method. After initial calculations, the CoV turned out to be higher than 0.2, but during further statistical analysis a bimodal distribution has been determined. The reason for the bimodal distribution was animal herding, effectively causing significant changes in animal density values depending on whether the herd was present. Missing a herd of animals during a single day of counting resulted in a data point that is inconsistent compared to days that the said herd was detected. The herding behavior of animals and detecting them turned out to be a crucial issue that needs to be identified to yield accurate and repeatable surveys and requires further investigation. The thesis concludes that UAV surveying is a viable methodology that is being successfully used in animal counting, and that will likely continue to grow in popularity. However, it requires proper preparation and knowledge.
