Russian scientists have found the solution
A team of scientists from Vyatka State University has developed a set of recommendations for supporting the natural regeneration of unique pine forests in the taiga zone. Experiments were conducted in the Medvedsky Bor of the Nolinsk district in the Kirov region—a natural monument, a relic pine forest on dunes with karst relief forms.
With the devised method, it will be possible to accelerate the restoration of open and lily-of-the-valley pine forests, avoiding the costly artificial restoration of forest cover.
According to the scientists, in pine forests, spruce and birch eventually begin to grow actively, disrupting the ecological niche and reducing the light regime for other plants. Subsequently, pine forests gradually transform into spruce stands.
For instance, the scientists proposed implementing gradual strip cuts in the area of regulated forest use to facilitate the natural regeneration of pine. To promote natural forest regeneration, it will also be necessary to conduct thinning of forest plantations, mineralize the soil surface using mechanical means. Additionally, to achieve the desired effect, attention must be paid to preserving the undergrowth.
