Comparative Analysis of Conditions for Scotch Pine (Pinus sylvestris L.) and Korean Pine Plantations (Pinus koraiensis Siebold et Zucc.) on the Territory of Vladivostok Agglomeration

Abstract

The forest cover of the Far East is very high. The forests of the Russian Far East (FE) occupy from 3 to 16% of the areas, that is stock of wood, and biological diversity of this form of vegetation cover. In order to restore and diversify the forest fund in Primorsky Krai, to determine the possibility of obtaining various wood within a short time and the possibility of switching to mass planting, pure crops of Manchurian walnut, Manchurian ash, Amur cork tree, Maksimovich poplar, Korean pine and Scotch pine has been created on the territory of the state forest fund since the early 1950s. The article analyzes the growth of Scotch pine (Pinus sylvestris L.) and Korean pine (Pinus koraiensis Siebold et Zucc.) plantations. The yield class, age, diameter and height, density and stock were determined on 5 trial areas. The analysis of the condition of artificial plantings for Korean cedar and Scotch pine, which were planted from 1954 to 1980, indicates their low capacity for survival, which decreases to 14–25% in 25–40 years, depending on the location of the research object. It confirms the need to expand and reconstruct the green zones of towns of “Great Vladivostok.” The main reasons for reducing the capacity for survival of plantings are forest fires and unauthorized logging.
