Abstract

To carrying out the research, 39 temporary indicator plots were laid in various types of pine forests on the territory of the forest fund of 12 forest enterprises of Belarus in the areas where renovation felling was carried out.

In the course of the research, it was made an assessment of the natural regeneration in pine stands with renovation felling carried out in them, taking into account the type of forest, the stand density after the felling, the presence or absence of undergrowth before the renovation felling.

As a result of the research, factors were identified that have a direct impact on the success of the regeneration processes under the canopy of the stand after the renovation felling. One of the most important factors affecting the pine natural regeneration is the density of the forest stand after renovation felling. It was found that the most optimal value is 0.51–0.60. A lower value of stand density promotes the growth of herbaceous vegetation, a higher value – a lack of illumination under the canopy of the stand.

As a result of a comprehensive analysis, possible ways of forming sustainable pine forests by renovation felling are proposed. Also, recommendations are given on measures to promote natural forest regeneration and technologies for renovation felling.
