Impact of 2021 Forest Fires on Ground Cover Vegetation in Lena-Vilyui Interfluve Forests

The influence of catastrophic forest fires on the ground cover in the forests of the Lena-Vilyui interfluve has been studied. The results show changes in species diversity and reserves of aboveground phytomass of the ground cover in the larch and pine forests in natural and burnt states. A correspondence analysis of species composition on the control and the burnt sites showed that the control pine and burnt forests have similar distributions, and the control larch and burnt forests differ in the distribution of species. When compared with 2022, in 2023, the burning of larch and pine forests showed an increase in aboveground phytomass by 1.6 and 4.4 times, respectively.
