For natural pine forests in the southern part of the Primorsky Krai, an assessment of biological diversity has been performed based on the results of descriptions of valuable tree species, living ground cover and carabid beetles Carabus. Field work was carried out on the trial plots laid in the forest plantations of the pine and broad-leaved forest with the domination of Korean pine Pinus koraiensis Siebold & Zucc. Model sites contained a chronological sequence of development of forest plantations of fresh small-grass and different-bush type on the interval of age 50-200 years. In the process of reforestation, a decrease in the total projective coverage of living ground cover was observed, while the number of species characteristic for natural pine forests, as well as their leveling, increased at the same time. By the age of 200 years species richness and leveling of the number of ground beetle species have reached a maximum. Statistically significant difference was found between the total number of caught insects in the plantations of 50 and 200, 80 and 200 years. The most valuable in terms of biological diversity are the old-growth pine forests. A conclusion was made about the value of this group of forests for the protection of valuable communities and habitats of species. Among ground beetle species Carabus schrencki Motschulsky, Carabus maacki Morawitz and Carabus macleayi Dejean can serve as an indicator of forest value. With a minimum total projective coverage (8.3 %), 200-year-old pine forests are favorable for the growth of such characteristic species as the mountain peony Paeonia oreogeton S. Moore, pale-mountain Dryopteris crassirhizoma Nakai, and the Pale Indian Plantain Cacalia auriculata H. Rob. & Brettell. On this site the Shannon index of species of living ground cover was 3.6, the Carabus species is 1.4.
