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.

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.

The article presents the results of the research on the features of <italic>Pinus sylvestris</italic> 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.

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.

Trees happen to be a prominent source of nutritive fodders and provide sufficient nutrients to the cattle throughout the year. The leaves of two <italic>Bauhinia</italic> species, that is, <italic>Bauhinia retusa</italic> and <italic>Bauhinia variegata</italic>, 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 <italic>B. retusa</italic> 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 <italic>B. variegata</italic> 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 <italic>Bauhinia</italic> species are good sources of green fodder for cattle, especially in the rainy season in case of <italic>B. retusa</italic> and in the summer season for <italic>B. variegata</italic>, to correct the deficiency of protein in animals in the hill state of Uttarakhand, India.
