Abstract

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.

Highlights

The forest cover of the Far East is very high
The paper analyzes the growth of Pinus sylvestris L. and Pinus koraiensis Siebold et Zucc
About 20 billion m3 of timber is concentrated here, about 274 million hectares are occupied by forests, which is about 29% of forest reserves and 46% of the entire forest territory of Russia (Analysis of statistical reference data of DalNIILKh, 2015)

Summary

Introduction

The forests of the Far East (FE) of Russia contain from 3 to 16% of the area, timber reserves, biological diversity of this form of vegetation cover. Since1950-70s,on the territory of the forestries of Primorsky Krai, the main introduced species was Pinus sylvestris, which was massively planted in the late 1960s and early 1970s. The condition of this species on the territory of the Vladivostok forestryas a whole, as well as in the Primorsky Krai, is unsatisfactory (Belov A.N. et al 2020).in the 1970s,the scientific community decided not to create forest cultures of non-zoned species.
