摘要

The issue of conservation and recovery of animal populations is multifaceted and largely determined by the ecology and biology of the species. In the case of the Arctic fox Vulpes lagopus, it is important to protect not only the animals themselves, but also, their dens, which are important for the long-term reproduction of the population. This study aimed to locate and verify Arctic fox dens reported in 1933, using a novel approach combining satellite imagery and field surveys. By analyzing freely available high-resolution satellite images, we identified potential den locations and then conducted field observations to confirm their existence. We found that two of the dens reported in 1933 are still in use for breeding, and we discovered other dens during our fieldwork. This study demonstrates the effectiveness of using satellite imagery to locate Arctic fox dens, particularly in remote and inaccessible areas. Our findings provide valuable insights into the species’ habitat use and breeding habits, and the importance of preserving such areas under the increasing threat of active industrial development in the region. Our study informs conservation efforts and highlights the need for continued monitoring and protection of the Arctic fox population on the Kola Peninsula.
