Reconstruction of Low-value Plantings as an Element of Sustainable Forest Management in the South of the Russian Far East

The article presents the research results of low-value oak plantations in which, in the first half of the 90s of the XX century, measures were taken to reconstruct these objects by forest plantation development created by planting Korean cedar seedlings in previously prepared corridors in the south of Primorsky Krai. The paper analyzed the variability of the main taxation characteristics of the created stands according to the following indicators: average height, average diameter, volume of growing stock as of 2021. The capacity for survival of plants in stands, diameter distribution were studied. According to the research results, it was found that the work performed on the reconstruction of oak forests of mixed origin, despite the admitted deviations from the reconstruction project, has led to positive results. To achieve the best results, it is necessary to adjust the rate of planting seedlings per hectare of the area. The optimal planting rate is 1-1.5 thousand of pcs/ha. It is advisable to increase the distance between plants in the planting row up to 1.5 -2.5 m. After reconstruction works, it is necessary to provide for forest tending in the plantations aimed at creating optimal conditions for the formation of valuable cedar-broad-leaved plantations. It is concluded that it is advisable to carry out the work on reconstruction of low-value plantations of coppice and mixed origin in the southern regions of the Russian Far East in order to achieve the goals of sustainable forest management of the region's forests, including the preservation of their biodiversity.
