Abstract

Oak is one of the most important woody plants in the Far East. It is of great national economic importance. The article is devoted to the study of species diversity, as well as the distribution of the oak area and its stock in the Far East in the period 2016-2023. The work is based on the analysis of the sources of literature and forest inventory materials on the topic of research. Within the Far East, there are four species of the genus Quercus, namely: Mongolian oak (Quercus mongolica Fisch. Ex Turcz.), Japanese emperor oak (Q. dentata Thunb.), mizunara (Q. crispula Blume) and Quercus wutaishanica Mayr (Q. wutaishanica Mayr.). It was found that over the last 7 years the area of oak distribution in the region, especially in Primorsky Territory, has decreased. This is due to forest fires, illegal cutting of timber. One of the ways in which it can be restored can be the use of growth stimulants in forest nurseries when growing seedlings. Sowing of oak acorns under the forest canopy, in burned areas, clearings, as well as wastelands and areas not covered with forest vegetation is possible with the help of a manual cane seeder.
