Journal Title: Лісівництво і агролісомеліорація - Year 2014, Vol 124, Issue
Abstract
In this study, the structure, sanitary condition, and peculiarities of formation of pine stands in Eastern Polissya of Ukraine were analised. The comparison of the effective and potential productivity was made. The research was carried out by a method of permanent sample plots. Affection by pests and diseases, and other defects and external signs which caused wood defectiveness were noted during visual diagnosing trees by sanitary state categories Due to the exceeding area of approaching maturity forests and decreasing young stands the age structure of pine plantations is not optimal. The sanitary condition of mixed pine stands is relatively better than pure stands’ one. Pine stands of mixed composition are highly biologically stable and can accumulate significant standing volume with regular tending. The actual productivity of pine plantations is 34–90 % of the potential one.
