To the elements of topiary art belong: shaped plants, plant-borders, hedges, living walls, pylons, berso, bosquets, and parterres. In PMsLA “Bondaretsky” and “Vysokivsky” were found no elements of topiary art. In nine PMsLA and five CMsN of Ukrainian Polissya were present five elements of topiary art (plant-borders, hedges (low, medium, high), living walls, pylons and shaped plants (ball, pyramid, cone, cube, complex geometric figures). The most common are plant-borders formed from Buxus sempervirens L., trimmed hedges from Picea abies Karst. and Thuja occidentalis L., untrimmed hedges from Juniperus sabina L., Physocarpus opulifolius Maxim., and Sorbaria sorbifolia (L.) A.Br., pylons and shaped plants in the form of a sphere, cube, complex geometric shapes - from Thuja occidentalis L. 12 families, 24 genera, 24 species, and 3 cultivars represent the systematic structure of woody plants in the elements of topiary art. Deciduous species of woody plants, namely the family Rosaceae Juss, prevail. In the elements of topiary art of PMLA and CMN there are species that are protected by the IUCN Red List (58 %), belonging to two categories of rarity NT (4 %), LC (54 %). In terms of the height of woody plants in the elements of topiary art, trees and shrubs are represented in equal numbers. By height, among tree plants prevail trees of the first magnitude 26 % and medium bushes 29 %, whereas there are slightly fewer trees of the fourth magnitude (15%) and high bushes (22 %). The condition of woody plants of 24 species and three cultivars is good, except for woody plants where timely and proper care was not carried out (formation of longitudinal and transverse profiles and annual pruning). Some plants should be replaced because of loss of aesthetics due to age.","PeriodicalId":425527,"journal":{"name":"Ukrainian Journal of Forest and Wood Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129300044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, there is a need for rationing and economic evaluation of these types of activity. Technical standardization of labor is an important stage in the implementation of innovative approaches, technologies, techniques, engineering samples and appliances in all spheres of production. This study serves the purpose of assessing the economic performance of unmanned aerial vehicles at aerial field work during forest management planning activities. The separate unit of the National University of Life and Environmental Sciences of Ukraine “Boiarka Forest Research Station” was identified as the base enterprise. The main analyzed means of technics within the scope of this research is the copter type unmanned aerial vehicle DJI Phantom 4. Based on the data of motion and time study of a quadcopter operator’s shifts, a rational balance of working time of a shift alongside with the normative indicators of labor productivity during aerial photographing activity were calculated. It is possible to adjust the production rate depending on the total travelled distance during a working shift. On the basis of the developed standards of labor productivity, the full prime cost of carrying out aerial photography on an area of 1 ha has been calculated. A comparison of the cost of carrying out aerial photography by means of an unmanned aerial vehicle with the cost of forest management planning and forest certification fieldwork has also been carried out. The results of the study suggest that provided the comparable qualitative and quantitative indicators of the collected data, the use of unmanned aerial vehicles for local clarification of the situation is less expensive compared to surveys by field teams.","PeriodicalId":425527,"journal":{"name":"Ukrainian Journal of Forest and Wood Science","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123238823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Indicator of tension in the living space of protective forest stands","authors":"V. Maliuha, V. Minder","doi":"10.31548/FOREST2020.04.005","DOIUrl":"https://doi.org/10.31548/FOREST2020.04.005","url":null,"abstract":"The density of stands remains a controversial issue to this day, requiring a practical solution in terms of the optimal liquefaction of plantings without a significant loss of the quantitative productivity of the trunk stock of wood and the stability of forest stands. Only as a result of focused efforts can the patterns of natural liquefaction or the process of self-regulation of complex biological systems, to which the forest belong, be achieved. Natural liquefaction of forest stands is an extremely complex process due to its multifactorial nature, to the manifestation of which climatic, soil, biological conditions and many other mutual influences are involved. In forest biogeocenoses, the edifacatory role belongs to the main stand. This tier represents a group of tree species in a phytocenosis, which determines its structure and, to a certain extent, composition. In this study, it is proposed to evaluate the functional load by an indicator of the tension of the living space of the plantation. Since Scotch pine is one of the most common edificators, widely used in the creation of anti-erosion plantations on soils of varying degrees of washout, substantiation of the indicator of tension is carried out on its example. The formula for calculating the tension indicator of the living space, characterizing the growing conditions of the plantation, is given. The indicator of the tension of living space is the ratio of the average height of plantings to their absolute completeness. The verification of the proposed indicator was carried out using tables of the course of growth, highlighting the patterns of the structure of tree stands. A graphic interpretation of the static research of forest stands is carried out. If the values of the tension indicators coincide with the distribution curve obtained from the standard tables of the sum of the cross-sectional areas of tree trunks with a completeness of 1.0, this indicates the optimal use of living space by plantations. The values of the indicators placed above the curve indicate the intensive use of living space. If the values of the indicators are located under the curve - it is incomplete use of living space. Since there is continuous forest management in Ukraine, and for timely forestry measures, it is necessary to constantly monitor the state of plantations. For successful cultivation of anti-erosion plantings of sufficiently high productivity and convenience of monitoring their condition, the proposed indicator can be used.","PeriodicalId":425527,"journal":{"name":"Ukrainian Journal of Forest and Wood Science","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114357862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The efficiency of production of this function significantly depends on the balance of management decisions regarding forest management and rational use of forest resources within radiation-contaminated areas. The information base for ensuring sustainable forest management, including monitoring of radionuclide migration in forest ecosystems of the Exclusion zone, is represented by a set of reference and information support, an important component of which are yield tables for modal stands. In order to supplement this complex with information on the peculiarities of Scots pine stands growth, mathematical models of dynamics of biometric indices are proposed and forest typology-based yield tables of modal pine stands of Chernobyl Exclusion Zone are developed within this work. The information basis of the research is presented by information from the database of IA “Ukrderzhlisproekt”, which contains the biometric assessment characteristics of Scots pine stands in the study region, as well as data from 18 temporary sample plots. In course of modelling, power and exponential growth functions were used. As a result, mathematical models of mean height, mean diameter, sum of basal area, growing stock and total productivity of pine stands of the studied region are proposed. These mathematical dependences serve as a basis for the development of forest typology-based yield tables for modal Scots pine stands. In particular, yield tables for modal pine stands growing in dry infertile pine sites, fresh infertile pine sites, fresh fairly infertile pine-oak sites, moist fairly infertile pine-oak sites and moist fairly fertile hornbeam-oak-pine sites are proposed. The developed mathematical models describe the dynamics of biometric indices for more than 90 % of the area of Scots pine stands in the study region.","PeriodicalId":425527,"journal":{"name":"Ukrainian Journal of Forest and Wood Science","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124772472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today this wood is used mainly for the manufacture of wood-fuels facility in industrial and municipal energy. A possible way to use it is making insulation material from wood wool. The existing prototype of such material - fibrolite contains woody wool of healthy wood but during burning emits toxic chemicals. The construction of wooden wall panels, which include a frame of lumber and thermal insulation material of wood wool, made of low quality pine wood and binder. The binder used were inorganic (liquid glass) and organic-mineral (PVA) dispersion with the addition of flame retardant. Investigation of fire resistance, acoustic and thermal insulation of material from low quality pine wood have proved that it meets the regulatory requirements and can be used in building structures. To develop technological requirements for the manufacture of wall panels using low-quality pine wood, it is necessary to determine their density, sorption capacity and bio-stability. For this purpose, samples of thermal insulation material with different content of mass parts of wood wool and binder were made. The density of specimens of insulating material (145‒250 kg/m3), which is close to the popular hard thermal insulation materials, has been determined. Experimental studies of moisture absorption, sorption capacity and swelling values indicated that the effect of moisture on the properties of insulating material and its shape resistance are within the permissible values of regulatory documents for construction products. Wood treated with binders found to be used for the manufacture of insulation material has been found to have high biological resistance, which is more than 5-6 times the bio-resistance of untreated wood.","PeriodicalId":425527,"journal":{"name":"Ukrainian Journal of Forest and Wood Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133332891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
