Abstract
The influence of catastrophic forest fires on the ground cover in the forests of the Lena-Vilyui interfluve has been studied. Obtained results showed changes in species diversity, and reserves of aboveground phytomass of the ground cover in the larch and pine forests in natural and in burnt state. The correspondence analysis 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 forest differ in the distribution of species. 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.
