【 摘 要 】

The population of the Eurasian beaver (Castor fiber L) significantly decreased in the Kursk region (Russia) in 70-90 of the twentieth century. The opposite picture is observed from the beginning of the 21st century. There is a significant increase in the population of beavers leading to enormous environmental problems. In this regard, the task for controlling the size of beaver population to minimize the environmental damage to their habitat falls on man. The first stage to complete this task is to measure the exact number of the Eurasian beaver population, and the second one is to optimize its number in accordance with the land capacity. Measurements in all districts of the Kursk region from 2013 to 2018 has been carried out using the method of linear accounting of the population and visual inspection. The result of the work is to identify the trends and dynamics of the beaver population, and to regulate the beaver population in accordance with the specificity of their habitat lands in future.
