Purpose. The purpose of this work is to investigate the ecological-and-economic aspect of certain factors to ensure the balanced use of forest lands; develop proposals for the formation of the basis for the development of sustainable forestry. Methodology / approach. We used the following methods: dialectical method of cognition for the analysis of scientific works of scientists concerning problems of balanced use of lands of forestry purpose; method of analogies (transfer of patterns of development of one process with certain amendments to another process or territory); statistical (based on quantitative indicators that allow drawing conclusions about the pace of the process); comparative analysis (comparison of indicators of forest resources and their use for Ukraine and Poland); correlation analysis (identification of factors on which the forecast significantly depends; clarification of relationships, their relationship with the predicted phenomenon under the influence of certain factors), graphical, abstract-logical (theoretical generalizations and formulation of conclusions). The information base of the study is the data of the Global Assessment of Forest Resources of FAO 2020, the data of the Monitoring of Land Relations in Ukraine, the reporting of the State Forest Agency of Ukraine, the data of the Forest Stewardship Council®. Based on the annual reports of the State Forestry Agency of Ukraine, some indicators of the report of 288 state forestries for 2018–2020 are consolidated in terms of 24 regional departments of forestry and hunting. Results. In the dynamics for 2018–2020, changes in the volume of forest resources, forest reserves, biomass, and carbon density were studied; the indicators of forest resources and their use for Ukraine and Poland are compared. The volumes of forest certification by regions of Ukraine are estimated. The relationships between capital investments in forestry production and the price of sold wood, the volume of net income of state forestry, the amount of profit, the degree of depreciation of fixed assets; between the tax burden on state forestries and financial stability was studied. Based on the assessment of the relationships and changes in individual indicators, the need to update the fixed assets of forest enterprises through the improvement of the investment instrument is justified. The results of this study are a summary of evidence on the environmental and economic aspects of the impact of certain factors on the sustainable use of forest lands, which in turn forms the scientific basis for achieving the goals of state environmental policy of Ukraine. Originality / scientific novelty. The studied interdependencies between the statistical characteristics of individual indicators of forestry land use made it possible to identify factors to ensure balanced use of forestry lands. It is substantiated that reforestation, forest certification, renewal of fixed assets of forestry enterprises through the improvement of the investment instrument, optimization of the tax burden of forestry activities are favorable factors to ensure the balance of forestry land use. It is proved that the excessive tax burden is a deterrent to the balanced use of forest lands. It is proposed to alleviate the tax burden on forestry activities by reducing the rate of deduction of net income of state forestry enterprises, eliminating the problem of double taxation of the forest fund, which under limited budget funding will allow state forestries to accumulate their own financial resources to ensure sustainable land use. Practical value / implications. The main results of the study can be used to: (I) structure the factors of sustainable use of forest lands; (II) defining the goals of sustainable development when developing the strategy of forestry enterprises; (III) analysis of the achievement of sustainable development goals at the national level, defined by the Basic Principles (strategy) of the state environmental policy of Ukraine for the period up to 2030. The results of the study can be used both at the level of forest management entities, as well as at the regional and national levels, to make management decisions on the implementation of measures that ensure the balanced use of forest land. Also, the causal links between indicators that arise from the response of indicators to certain factors open up new opportunities for forest management planning. These results can provide important information for the protection and use of forest resources in all regions of Ukraine.

Species composition of lawns in the housing estates, planted – among other reasons – in order to diversify the urban landscape, is often modified and enriched with other, spontaneously appearing species. The aim of the present work was to determine the floristic and phytosociological diversity of selected housing estate lawns of three different age groups, in the city of Szczecin, in three neighbouring housing estates (Niebuszewo, Warszewo, and Żelechowa). It was assumed that over the years, lawns are gradually becoming weaker, which may be due to the occurrence of negative anthropogenic factors of increasing intensity. It was found that despite the one designated plant community in all the analysed housing estate lawns (namely, Poa pratensis – Festuca rubra), there are differences between the studied areas, in terms of the number of species occurring therein, and the values of selected ecological (environmental) indicators.

Riparian hardwood forests have become very rare in most areas across Europe, as their fertile habitats have mostly been transformed into grasslands and arable land. Furthermore, where small patches remain, these are seen to be subject to major changes in soil cover and plant composition, thanks to habitat change induced by drainage, river engineering, the construction of river embankments and forestry. A further, highly visible symptom of the degradation of riparian hardwood forest is invasion by alien species (neophytes). This article therefore draws on work to analyze Poland's vegetation of riparian hardwood forest, by reference to some 249 phytosociological relevés from 83 sites located along river valleys (Fig. 1). The work came within Natura 2000 habitat monitoring, and specifically a research project entitled Riparian hardwood forest services in the middle Vistula river valley. The main objectives here were to point to any relationships that might pertain between the share of invasive alien species and the structure and composition of riparian hardwood forest vegetation, as well as to determine the former's habitat requirements.
