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.

Relevance. One of the main methods of reforestation is the use of growth stimulants, which are widely used in agriculture in Russia and abroad. In forestry, their use is carried out on an experimental basis. The increase in the sowing qualities of seeds, in the biometric indicators of seedlings is observed, their safety is activated. In this regard, the use of such growth stimulants as Zircon, HB-101, Root Super and Ferovit is relevant.Methods. The effect of root feeding with stimulants Zircon, HB-101, Root Super and Ferovit on the biometric parameters of four-year-old seedlings of Khingam fir (Abies nephrolepis (Trautv.) Maxim.) was studied. The experiments were carried out in the nursery of GTS — the branch of Federal Scientific Center of the East Asia Terrestrial Biodiversity FEB RAS. The growth of seedlings was studied in terms of stem height, height gain and root collar diameter.Results. It has been established that root fertilization with the stimulants Zircon and HB-101 has the greatest effect on the growth of fir seedlings. The increase in the height of seedlings is by 3.9–60.7%, in height gain — by 11.4–137.1%, as well as in the diameter of root collar — by 16.7-66.7% was noted. It was revealed that the use of the stimulator HB-101 in the solution concentration of 0,5 ml / 10 l has a more positive effect compared with the concentration of the drug solution of 0.5 ml / 5 l of water.
