Post-fire reforestation of pine forests adjacent to the tukulans of the Lena-Vilyui interfluve

Abstract

This article presents the results of forestry and geobotanical studies of post-fire communities in pine forests adjacent to large sandy deserts, tukulans, in the Lena-Vilyui interfluve. Pine forests, which are widespread in the middle and around the tukulans, have recently become highly susceptible to fires, as the entire territory of the Lena-Vilyui interfluve. In 2019, we collected materials on post-fire communities in multi-age burned areas, which supplement a few pieces of information regarding post-fire reforestation. We found that the vast areas of the studied region were occupied by pyrogenic communities. We assumed that the natural regeneration of Scotch pine in the vicinity of tukulans was unsatisfactory, with 0.3–0.95 thousand pieces of pine undergrowth/ha. Post-fire communities can become launching pads for the development of modern aeolian processes or can expand the area of existing tukulans.
