Abstract
Renovation felling in the pine forests of Belarus can be carried out both with chainsaws and multiplefunction logging machines.
To carry out the research 50 trial plots were laid in the pine forests of the country where the first step of renovation felling was carried out. As a result of the analysis, it was found that in 86% of cases, renovation felling was carried out using chainsaws and a loading-transport machine by the method of uniform selection of trees. In 6% of cases renovation felling was carried out by multiple-function logging machines using the method of uniform selecting of trees. There were no cases of renovation felling by multiple-function logging machines using the method of uneven selecting of trees.
As a result of the research, it was found that renovation felling by the method of uneven selecting of trees has a greater silvicultural effect in comparison with the method of uniform selecting of trees.
It is proved that after the first step of renovation felling in Pinetum pleuroziosum using methods of uneven selecting of trees (felling down narrow strips 10 m wide or areas 0.06 hectares in size), the amount of pine undergrowth is on average 3 times higher, and the proportion of healthy pine undergrowth is on average 29.3% higher than after felling by the method of uniform selecting of trees.
