It is necessary to study the parcel structure dynamics of forests in Primorskii krai to identify the natural restoration patterns of a unique formation of the region: primary coniferous–broadleaved forests. As a result of economic activity, these forests, rich in relic elements, were replaced by secondary ones in most of the affected area. The studies were performed in the catchment area of the Komarovka River (Southern Primor’e, Ussuri district). The article presents the results of the study of the parcel structure of broadleaved–linden with lianas hasel forb type of forest, which is representative for the region and is the most complicated as far the derivative forests formation is concerned. The research was performed by the conventional method: a detailed description and mapping on a scale of 1 : 100 of all phytocoenosis layers on a permanent test plot (PTP), followed by a pairwise comparison of maps and isolation of parcels. An analysis of the phytocoenosis transformation over a 20-year period of restorative succession has shown that the main forest and taxation characteristics of the stand insignificantly changed. Aspen and a considerable part of linden almost completely disappeared from the stand, the latter being one of the main species of the local ecosystems. The positions of the underbrush and the tree species characteristic of primary coniferous–deciduous forests were strengthened. Changes in the parcel structure indicate the successful restoration of the primary forest type: two secondary complementary (small) parcels disappeared in the phytocoenosis, and one more parcel has joined the six conditionally—indigenous ones. There was also a natural enlargement of conditionally—indigenous parcels and the alignment of their boundaries. During the research process, a high indicator role of the herbaceous layer was revealed.
