Peculiarities of growth and development of pine forest plantations in the Ukrainian Carpathians by forestry districts: Precarpathian, Mountain Carpathian and Transcarpathian plains and foothills are determined. Mathematical dependences of pine growth and development on age, height and diameter are offered. According to the obtained mathematical empirical dependences, it was established that Scots pine (Pinus sylvestris L.) grows and develops better in the Mountain Carpathian forest district. In the Mountain Carpathian Forestry County, the growth of pine is dominated by 2% for the Precarpathian forest district, and in Transcarpathian plains and foothills by 1%. By completeness in the Gorge of Cocarpathian forestry County, the diameter of the pine is higher than the Carpathian forest county on the 3%, and the Transcarpathian plains and the foothills — 1%. Using the Microsoft Excel data analysis package, correlation matrices were constructed and regression and variance analysis of such indicators as: age, height, diameter, phytomass — wood, bark, and crown was performed. Mathematical equations were obtained, which made it possible to establish the biological productivity of Pinus sylvestris L. Using the obtained empirical equations according to the methods of IPCC (Intergovernmental Panelon Climate Change, 2015), G. Matthews (1993) and I.Ya. Liepa (1980) established the carbon-absorbing and oxygen-forming capacity of pine tree plantations at the age of 70 on an area of 1 ha. It is determined that on the area of 1 ha pine plantations absorb the most carbon — 88.9 tons, and produce oxygen — 262.2 tons in the Mountain Carpathian Forestry District, in the Precarpathian Forestry District 76.0 tons of carbon and 224.1 tons of oxygen, in the Transcarpathian plains and foothills Scots pine absorbs 69.5 tons of carbon and produces 204.9 tons of oxygen. The amount of CO2 emissions into the environment in the conditions of the Ukrainian Carpathians is analyzed, it was established that pine forests reduce carbon dioxide emissions by 32%.

The City

Suburban recreational forests of the city of Voronezh have medium-forming, water-protective, protective, aes-thetic, recreational value. As a result of increasing recreational loads, there are noticeable changes in natural complexes, their condition worsens and productivity decreases. The purpose of the study is to determine the vital state of trees in artificial pine plantations of various stages of digression by the phenotypic features of the trunk and crown and the development of methods for their diagnosis. In carrying out the studies, standard methods of forest inventory have been used with the corresponding cameral treatment. An algorithm is proposed to regulate the research. Detailed data are provided for each stage of work. With deterioration in the sanitary condition of the plantations, a significant decrease in the number of healthy trees has been revealed. The data of the revealed external signs of pathology in Scots pine in the studied stands are reflected. The most common anomaly in the 63-year-old stands of different stages of digression is the curvature of the trunks. Their number regularly increases from 15% in I stage to 63% in the V stage. Mechanical damage to the trunk (from 7% to 37%)are in the second place in the occurrence of I - IV stages of digression in plantations, stem rot (48%) - in the V stage. Such defects as taring and stem rot have the least spread in plantations of I-III stages of digression. The basis of natural regeneration in 63 years old forest cultures of Pinus sylvestris is pine single and group undergrowth of different ages. Indicators of the life condition of trees in conditions of recreational impact are: the shape of the trunk, the presence of multiversity, density and architectonics of the crown, the degree of drying, angle of the branch from the trunk in the lower, middle and upper parts of the crown. Scale for determining the viability of trees by phenotypic characteristics has been proposed. Measures were taken to restore disturbed stands using highly viable species and selected individuals.

The aim of work was to investigate the qualitative and quantitative characteristic features of soil fungi associations occurring in I class pine stands threatened by pathogens of tree roots in Zielonka Experimental Forest District. During the mycological analyses of soil, a total of 694 isolates of fungi representing 33 species were obtained. The most numerously represented species was <em>Penicillium daleae</em> which made 75% of all isolates. The second place in the ranking belonged to <em>Penicillium janczewski</em> amounting to 11%. In order to define the qualitative and quantitative similarity between the studied areas, a proportional inconformity was determined. The greatest similarity occurred between the associations of soil fungi obtained from site 64c and 35b.

Special Relevance

Recreational use of forest resources is the most important for urban green forests. Every year the problem of satisfying the population growing needs for recreation in the forest, while ensuring its preservation, acquires special relevance. The main function of Somovskoe Forestry (Voronezh region) is environmental protection, which includes the implementation of protective, water conservation, and recreational functions. Grass pine forests are the most comfortable for vacationers in Somovskoe forestry. In the study, the recreational potential of the Somovskoe Forestry (Voronezh region) has been estimated based on the methods of various authors, types of landscapes, types and forms of recreation, stages of digression, planning and aesthetic value. It has been revealed that most of the plantations are occupied with a closed type of l of horizontal closeness. The predominant class of aesthetic evaluation of the examined stands is II. The largest area is occupied by the strata with III and IV stage of digression. The main types of recreation in the stands of Somovskoe forestry are everyday and camping ones. The main forms are off-road and road ones. The predominant class of aesthetic assessment is II (65% ± 3.2). It is a plantation with reduced visibility and patency. The recreational potential of the studied artificial pine plantations is not higher than class II. Recommendations on regulating the movement of vacationers with the goal of hindering the "development" of the entire forest area, the development of measures to improve the culture and discipline of recreants, to increase the sustainability and productivity of plantations have been given on the basis of research results.

Permanent Damage

In November 1958, an ice storm caused severe bending of stems in young red and Scots pine plantations on the Sandilands Forest Reserve in southeastern Manitoba. A study was carried out to investigate the recovery of bent trees and to determine the extent of permanent damage in the plantations.Between 50 and 100 per cent of the trees in young red pine plantations were bent so severely that their tops were touching the ground. Scots pine plantations were less severely affected. However, both species showed considerable recovery and little or no permanent damage has occurred in plantations younger than 14 or older than 25 years of age. Approximately one quarter of the trees growing in two dense red pine plantations, 16 and 22 years of age, were judged to have been permanently damaged.

Multifaceted Analysis

The aim of this work was to show the scale of occurrence of the Scots pine assimilation apparatus disease, spring rape, in the area of RDLP in Szczecin and submission of the collected results for the years 2008-2016 to a multifaceted analysis. The spring peat of pine is an important disease of crops and young trees in the Międzychód Forest District. The potential threat is registered in the Bogdaniec, Gryfice and Międzyrzecz Forest Districts. The Forest Districts of Choszczno, Głusko, Karwin, Myślibórz and Różańsko did not find any damages to the rash of spring pine in the period indicated. Analyzing the data provided, it is possible to describe the characteristics of the damaged areas within the RDSF Forest Districts in Szczecin: Scots pine aged 4.61 years on an area of 1.58 ha in 1.71 damage.
