The paper analyzes the growth of Pinus sylvestris L. and Pinus koraiensis Siebold et Zucc. Bonitet, age, diameter and height, density and resources were determined on 11 sample plots. The analysis of the state of artificial plantations of pinus koraiensis and pinus sylvestris, planted from 1954 to 1980, indicates their low preservation, which after 25-40 years, depending on the location of the research object, decreases to 14-25%, which confirms the need for expanding and reconstruction of green areas of the cities of the “Big Vladivostok”. The main reasons for the decline in the preservation of plantations are forest fires and unauthorized felling.
