Analysis of high-resolution satellite images taken during the cold part of the year demonstrates that they can be used to reliably distinguish the saiga from domestic ungulates and also to determine the distribution of saiga herds over large areas. To achieve maximum reliability in differentiating animal species in satellite images, one should use a number of characteristics (including the color of animals, their size and shape, and herd structure) and prioritize those that are most prominently displayed in particular images. The results of this study can be used to develop a non-invasive and highly accurate method for saiga census.
