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 dis
tribution 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.
