Coniferous and broad-leaved forests of the South in Primorsky Krai are unique plant communities that include trees and shrubs, ground cover, non-layered vegetation, as well as habitats for rare and endangered species of animals and birds. Woody flora is ancient and original and is determined by the interpenetration and interaction of various floras and plant communities in different past geologic times. It is composed of plant species both young and old relict species. In terms of their biodiversity, these forests occupy one of the leading positions in the world, and the stock of wood volume accumulated in these forests is an important component in regulating the balance of carbon storage and its release. Haphazard logging of these forests for half a century, the collapse of the fire protection system, the lack of proper and scientifically-based methods and ways of forest care have led to the fact that these unique plantings are currently on the verge of disaster and are losing their environmental and climate-forming functions. The case in point is the natural disasters that occur throughout the Far Eastern Federal district. The purpose of the research was to study the features of the natural renewal process of Fraxinus mandshurica to determine the silvicultural prospects for its use, to identify the planting areas suitable for growing this species in accordance with the order of the RF Ministry of Natural Resources dated March 25, 2019 No. 188 “Concerning Approval of the Rules for reforestation, the procedure for developing a reforestation project and making changes on it”. The Fraxinus tree, thanks to its powerful root system, is a well wind-resistant species and performs soil-protecting and shore-strengthening functions. In addition, it has a valuable wood that has a high cost both on the domestic and on the external market. At the same time, Fraxinus is very plastic to the conditions of the urban environment and can be used to create green areas around cities (Razlomiy et al. 2020). The common practice of reforestation activities in Primorsky Krai shows that the share of natural reforestation in the actual volume of renewal activities reaches 85%.
