Modern climate warming has become one of the most pressing environmental issues, posing a significant threat to ecosystems, economies, and societies worldwide. In 2021, which was recognized as an anomalously hot and dry year, large-scale landscape fires on the Lena-Vilyuy watershed destroyed approximately 1.4 million hectares of forest, leading to significant changes in the structure of biotopes at all levels. These changes included noticeable alterations in the physical and chemical properties and regimes of soils, which have long-term impacts on the ecosystem. As a result of comprehensive studies using classical soil science methods combined with geophysical techniques, the emergence of foci of long-seasonally frozen soils was identified for the first time in Central Yakutia. These soils develop on ancient alluvial deposits under the burned areas of larch and pine forests in the studied region.
