Abstract Currently, Ukraine is outlining a problem with the recruitment of students to the Faculty of Forestry. The solution to this problem is possible only if the necessity of transformation of the forestry industry and the corresponding transformation of the forestry education system are realised. Based on the study of scientific literature, the main motivating factors, according to which future students decide to become foresters, were identified. These factors were included in a questionnaire offered to first-year forestry students. The results of the questionnaire were compared with the data from the scientific articles. As a result, some aspects to pay attention to in order to increase the attractiveness of forestry as a field of study were identified. It was found that the predominant motivating factors for choosing a forestry profession are enjoyment of nature, recreation in nature, spending time in the fresh air, concern for the environment and interest in forests. Salary of forestry specialists proved to be the strongest factor for hesitation in choosing the profession. The next step of our research will probably be to investigate the opinion of Ukrainian students about the quality of educational programmes.

Abstract Trees happen to be a prominent source of nutritive fodders and provide sufficient nutrients to the cattle throughout the year. The leaves of two Bauhinia species, that is, Bauhinia retusa and Bauhinia variegata, were collected in different seasons from their natural growing habitats. The collected leaves were air-dried to make a fine powder, and the nutrient concentrations were estimated as per the standard processes. Significant variations were recorded in the nutritive values of both species in different seasons. The leaves of B. retusa revealed highest dry matter and total carbohydrate in the summer season, while the rainy season exhibited the highest value of ash per cent and crude protein.The ether extract and nitrogen-free extract per cent were higher in the winter season, and the maximum crude fibre and organic matter per cent were prominent in the spring season. In case of B. variegata leaves, the dry matter, nitrogen-free extract, ash and ether extract per cent were higher in the winter season. The highest crude fibre percent and total carbohydrate were found to be the maximum in the rainy season, and crude protein was higher in summer season. The results of the present study revealed that the both Bauhinia species are good sources of green fodder for cattle, especially in the rainy season in case of B. retusa and in the summer season for B. variegata, to correct the deficiency of protein in animals in the hill state of Uttarakhand, India.

Abstract The article presents the results of the research on the features of Pinus sylvestris L. condition and productivity in forest stands of the Left-Bank Forest-Steppe of Ukraine (in Kharkiv and Sumy regions) for 2006–2021. The study was carried out using the ‘Forests of Ukraine’ Database as of 01.01.2017, and the results of field research at 30 temporary sample plots (TSP), 3 permanent sample plots (PSP) (in 2006–2018), and 13 monitoring plots (2009–2021). Generally accepted methods and new standards were used. The dynamics of forestry and evaluation indicators of Scots pine stands at sample plots were analyzed and compared with high-productive Scots pine stands. The characteristics of natural regeneration are given. It was revealed that the age structure of pine stands is not optimal: there is an excess of middle-aged stand areas. Changes in the structure and development of managed Scots pine stands with respect to changing environmental conditions were observed for 2009–2021. Studied forest stands showed a tendency for negative changes in stand structural characteristics related to regeneration and growth. Drought mainly in combination with even medium anthropogenic impact can further worsen the health status of Scots pine stands in lowland areas of the Left-Bank Forest-Steppe of Ukraine. Thus, the formulation of forest management measures to mitigate the impact of these stress factors is needed.

Abstract Forests of Ukraine and the whole world in recent decades are regularly exposed to uncontrolled large wildfires. In Ukraine, huge forest areas were burnt in 2009, 2014 and 2015. In 2018, even the northern Scandinavian countries suffered from forest fires. Global climate change (increasing average temperature and aridity) is expected to contribute to the increasing number and area of fires in the future. The occurrence of fire is impossible without the presence of a source of fire, oxygen and fuel (so-called triangle of fire), but only forest fuel (FF) can be controlled by forestry treatment or by prescribed fire. Effective fire management is impossible without the knowledge of the distribution and qualitative characteristics of FFs. This article provides brief information on the history of research studies on FF in Ukraine and in the countries of the former Soviet Union and the factors that influence the formation of reserves and structure of FF. According to those research articles, the most important factors were soil and climatic conditions and characteristics of plantations. Information about the trends in accumulation of FFs in the Ukrainian pine forests is given. After the evaluation of the research works about FF, it was concluded that the study of fuel in Ukraine is fragmentary, and such studies should be continued, but necessarily after the unification of the methods of sampling and recording data about FF. In the future, this work allows the mapping of FF at the national level. The need to continue collecting field data from forest ecosystems is indicated by the use of new world-class methods for the development of fuel models, taking into account the local conditions.

Abstract Spatial planning and arrangement work of rural areas is constantly being renovated to improve the living conditions, land distribution and to facilitate work in this area by reducing the costs of transport. The most effective solution is consolidation and exchange of land, which is a difficult and time-consuming process. However, it significantly facilitates everyday functioning of the inhabitants of the village. It assumes reduction of plots of land belonging to the farm by increasing the area of other plots, regulating the shape, ensuring access to the public road and shortening the distances of individual farmland to their habitats (built on site). The purpose of this work was the analysis of land consolidation and exchange process for the village of Lukowa with the use of Geographical Information System (GIS) tools. Primary aim set at the beginning of the project is to compare the state before the land consolidation and the design of the parcel posting after consolidation. QGIS free software has been used to solve this problem. Two basic activities were carried out to compare the distance between built-up land and the remaining farmland. For this purpose, two analyses were performed: network analyses assuming the calculation of distance along the shape of roads and linear analyses determining the shortest distances between plots on a straight line. The work considers the real land distribution, the calculation of which is a time-consuming task. Many factors must be considered to accurately determine the correct distances. It is shown what difficulties and problems occur during the collection of data for analysis, with the correct indication of habitats and indicating the road network or aggregation of adjacent plots of one owner.

Abstract Black cherry, which occurs in European forests, contributes to their distortion or degradation of native ecosystems. Therefore, measures are taken to reduce its occurrence. One of them is the biological method involving grazing animals. The aim of this research was to develop and identify an attractant that would increase the attractiveness of black cherry as a feeding base for deer, which would limit its occurrence. This research was carried out in Zielonka (17.10941 E 52.553975 N). In the experiment, 3-year-olds were used: Tilia cordata, Acer pseudoplatanus, A. platanoides, Fagus sylvatica and Prunus serotina. Before planting the seedlings, their height was measured. The control (K, 10 trees) consisted of trees of each species that were not sprayed with attractants. Another set of 10 trees were treated over the entire surface of the shoots with a bait mixture (MW), and the next 10 trees were sprayed with a 10% aqueous solution of NaCl. The attractant spraying was repeated six times. All damage observed was recorded. The inventoried tree damage was divided into four categories: 0%, no damage; I, 1–20% damaged trees; II, 21–50% damaged trees and III, more than 50% damaged trees. The results of the Mann–Whitney U test (p = 0.0109), at the assumed level of significance (α = 0.05), showed that slightly higher seedlings were browsed. These studies indicate the potential of using attractants as preparations influencing the palatability of the black cherry for deer. All recorded bites were classified as degree I damage. The trees were gnawed by fallow deer, 35.33% of trees were not damaged by game at all, and 64.66% of trees were damaged in degree I. In the case of sycamore maple, Norway maple and linden, the bait mixture did not increase the number of nibbled buds and leaves, while NaCl increased the attractiveness of beech and black cherry as a feeding base. Conducting further research studies on the improvement of preparations may give a chance to reduce the use of chemicals in forest protection and give the possibility of using attractants where it is impossible to use herbicides.
黑樱桃生长在欧洲的森林中，导致森林生态系统的扭曲或退化。因此，采取措施减少其发生。其中之一是涉及放牧动物的生物学方法。本研究的目的是开发和鉴定一种引诱剂，以增加黑樱桃作为鹿饲料基地的吸引力，从而限制其发生。本研究在柴龙卡(17.10941 E 52.553975 N)进行，试验材料为3岁生木:桔梗木、假桔梗木、桔梗木、山毛榉和桃李。在种植幼苗之前，测量幼苗的高度。对照(K, 10棵)为每个树种未喷洒引诱剂的树木。另一组10棵树在枝条的整个表面施用诱饵混合物(MW)，其余10棵树喷洒10%的NaCl水溶液。引诱剂连续喷洒6次。所有观察到的损坏都被记录。树木的伤害分为四类:0%，无伤害;1-20%受损树木;II，树木受损21-50%，III，树木受损50%以上。在假设显著性水平(α = 0.05)下，Mann-Whitney U检验结果(p = 0.0109)表明，幼苗的浏览量略高。这些研究表明，使用引诱剂作为制剂可能会影响黑樱桃对鹿的适口性。所有记录的咬伤均为I级伤害。饵料混合物对梧桐枫、挪威枫和椴树的咬芽和咬叶数量没有增加作用，而NaCl对山毛榉和黑樱桃作为取食基地的吸引力增加。对制剂的改进进行进一步的研究，可能有机会在森林保护中减少化学品的使用，并在无法使用除草剂的地方提供使用引诱剂的可能性。

Abstract It was studied that the dynamics of phenophases, the dates of the beginning and duration of phenological cycles in plants are under the constant influence of seasonal changes in climatic conditions (regular alternation of seasons with different durations of day and night, warm or cold and rainy or dry seasons). Together with the study of the shoot growth duration, it is worth conducting a study of the dynamics of their growth. This is also important for determining the tolerance for winter conditions, since it is known, that not only those shoots that finish growing early but also those that grow for a long time, but rather slowly, can be winter resistant. The intensive growth of shoots of all studied species occurs in May to mid-June. Almost all of them have two peaks of shoot growth: June and mid-July. The growth of shoots has a certain dependence on air temperature. The conducted long-term phenological observations made it possible to establish the periods of phenophases in five species of shrubs and show that in the conditions of the Right-Bank Forest-Steppe, all of them manage to complete their vegetation in time, before the beginning of frost. Among the studied species, Lonicera tatarica L. and Viburnum lantana L. were the first to start their shoot growth in the first decade of May. Then, in the third decade of May, shoots of E. europaeus began to grow. P. spinosa and R. canina were the last to start their shoot growth. The conducted research has a certain significance for forest reclamation work as these types of shrubs are used to create protective plantings. Establishing a certain dependence on air temperature will allow to adjust the species composition and their number when creating this type of plantation.

Abstract The research was aimed at verification of the possibility and expediency of applying i-Tree Eco tools in order to assess the value of ecosystem trees and bushes by the example of one of the parks in Ukraine and representation of the obtained information on an interactive map. For this purpose, the inventory of 228 urban trees in Pryzamkovyi park was conducted and the possibility of its adjustment to the conditions in Ukraine was assessed. The obtained information was analysed and visualised, and the advantages and disadvantages of this process were determined. The scope of the provided ecosystem services for park spaces was specified and it was determined that urban trees in Pryzamkovyi park have a €12.38 million replacement value and the average indicator of annual usefulness of ecosystem services provided by one tree plant or one bush plant in the park is equal to €15.75 per year, according to i-Tree Eco assessment. In order to improve the process of obtaining, processing and visualising materials, an orthophotomap based on unmanned aerial vehicle survey materials was applied. It allowed increasing the accuracy and improving the visualisation of the geolocation of trees and bushes. In order to familiarise a greater number of users with this information, electronic maps of vegetation that display the location of trees and bushes and their ecosystem services, both in quantity and monetary terms, were offered. The peculiarity and the scientific novelty of the approaches to solving the assigned task is the improvement of the process of informing the interested parties about the ecosystem services of a specific tree in the park and green plantations in the park as a whole. The suggested approaches to assessing the value of urban trees and their ecosystem services give ground to emphasise the value of these plants for urban ecosystems, to substantiate the expediency of implementing environmental measures as well as the need to increase the funding of these measures as a compensation for the services provided by trees and plants. At the same time, it is worth mentioning the expediency of conducting further research on this subject and the related issues, which requires follow-up studying.

In order to familiarise a greater number of users with this information, electronic maps of vegetation that display the location of trees and bushes and their ecosystem services, both in quantity and monetary terms, were offered. The peculiarity and the scientific novelty of the approaches to solving the assigned task is the improvement of the process of informing the interested parties about the ecosystem services of a specific tree in the park and green plantations in the park as a whole. The suggested approaches to assessing the value of urban trees and their ecosystem services give ground to emphasise the value of these plants for urban ecosystems, to substantiate the expediency of implementing environmental measures as well as the need to increase the funding of these measures as a compensation for the services provided by trees and plants. At the same time, it is worth mentioning the expediency of conducting further research on this subject and the related issues, which requires follow-up studying.","PeriodicalId":35789,"journal":{"name":"Folia Forestalia Polonica, Series A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79585342","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}

Abstract Five different data fusion techniques (multiple linear regression (MLR), high-pass filtering (HPF), intensity hue saturation (IHS), wavelet transformation (WT) and the hybrid method WT + IHS) have been applied to model the aboveground forest biomass (AGB) in this study. The RapidEye multispectral image and the PALSAR radar image were used in research as sources of remote sensing data. Five models for estimating forest AGB were built and analysed using data from test area in Chernihiv region (Ukrainian Polissya). Correlation and min–max accuracy have been calculated for each model to measure the model performance. Among all the data fusion approaches used in the study, the high-pass filtering method has shown the greatest efficiency.

Abstract On 1 April 1963, the Department of Forest Fire Protection was established at the Forest Research Institute, which resulted from the need to develop scientific and organisational bases for building a forest fire protection system that would effectively minimise the growing fire hazard of Polish forests. The Department began its activities by developing a programme that took into account both the immediate but urgent needs of the forestry and the anticipated directions of research. Over the course of 60 years, more than 350 research reports were produced. Among the achievements that have influenced the currently functioning forest fire protection system in Poland there are: the method of forest fire risk assessment, forest fire risk prediction, the creation of fire risk monitoring based on a network of forest meteorological measuring points, the development of forest fuel models, the extensive use of aircraft to detect and extinguish forest fires, the conduct of the first studies on the possibility of using television cameras to detect forest fires, the operation of the National Forest Fire Information System, the purpose of which is to collect data on forest fires and natural non-forest areas, the development of an application for forest fire models and the conduct of the first workshop on controlled heath burn in the country. Among the many projects completed, there were also those dealing with the evaluation and suitability of equipment and chemicals for extinguishing forest fires.
