Abstract

The article shows how to determine the areal density and the number of marmots on satellite images. For the accuracy of calculations, by the authors there was modified the method previously used by Russian scientists. To do this, have been studied colonies of marmots in the area, were determined the number of permanent holes for the family, the number of animals in the family in the late spring and late summer. To determine the number of marmot burrows have been used specially developed formula. Map of area of distribution and density of marmots in the territory was compiled with the help of Photoshop, overlay of count maps on a clean map of hunting. The article shows that the calculation of the number of marmots on the satellite images provides reliable results.
