Abstract Ash dumps occupy significant areas around the world and make a negative influence on the environment. This effect is decreased by their natural colonisation determined by the bioclimatic conditions of the area. The purpose of the current study was to identify the structure of the forest communities and the initial stages of soil formation on the ash dump in southern taiga. This study was carried out on three sites in the forest phytocoenosis formed in the process of revegetation of the Verkhniy Tagil Power Station ash dump over 50 years, as well as on two background forest sites in the Middle Urals. Complex geobotanical and soil studies were carried out. The results of the study show that forest phytocoenoses with a predominance of hardwood species (Betula pendula Roth and Populus tremula L.) and a small admixture of coniferous species can form on the non-recultivated ash dump within 50 years in a boreal zone. In total, the studied mixed forest phytocoenoses are similar in composition to zonal secondary forests, but differ by having lower height and diameter of the stand, as well as herb–shrub layer coverage. Their species density and floristic richness are also lesser. The study proved that the process of soil formation is also proceeding according to the zonal type in the ash substrate under forest communities. The results of the study can be applied to justifying the forecasts of ecosystem restoration on the technogenic substrate, as well as for the species selecting for their recultivation in the studied area and similar to it.

The article is focused on microbiological and silvicultural properties of bacterial wetwood of silver birch (Betula pendula), also known as European white birch. During the active phase of the disease, bacterial wetwood (i.e. bacterial dropsy, vascular parenchymatous bacteriosis or flux slime) is characterised by crust and periderm bloating, necrotic wet stains and abundance of exudate. The disease is more likely to occur in older (r = 0.56, p < 0.01) and less-dense (r = −0.29, p < 0.01) stands. The statistical model showed that the chance of bacterial wetwood increases with birch age by 0.36% per year. The stands with birch proportion of over 70% demonstrated 15.3% lower infection rate compared to the stands with lower birch presence. The stands with lower stocking demonstrated a higher proportion of infected tree distribution by 7.5% compared to the stands with higher birch representation. The most vulnerable were larger, older B. pendula trees with longitudinally fissured bark that grow on poorer soils and experience frequent water stress. Birch associations with Pteridium aquilinum and Vaccinium myrtillus were more susceptible to infection (31.6% and 44.3%, respectively), whereas associations with Brachypodium sylvaticum, Sphagnum palustre and Calluna vulgaris were at lower risk. Strong ecological and trophic association of bacterial wetwood was present between silver birch and Tremex spp., particularly Tremex fuscicornis. Mycobiota was represented by Rhizopus microsporus, Mucor mucedo, Penicillium aurantiogriseum, Penicillium purpurogenum and Acremonium strictum. Enterobacter, Xanthomonas, Pantoea and Bacillus spp. associated with bacterial wetwood of silver birch were isolated. Enterobacter nimipressuralis was found to be the primary causative agent through means of artificial infection, while other bacteria were found to be either weak pathogens or concomitant. E. nimipressuralis formed the largest number of colony-forming units (CFU) for bark and cambium (164 and 127 CFU, respectively) and was also found in a small amount as a vital obligate in the automicrobiota in healthy birch trees.
本文主要研究了欧洲白桦(Betula pendula)细菌湿材的微生物学和造林特性。在疾病的活跃期，细菌性湿木(即细菌性水肿、血管实质细菌性菌病或通量黏液)的特征是外壳和周皮肿胀、坏死湿斑和大量渗出物。年龄较大(r = 0.56, p < 0.01)和密度较小(r = - 0.29, p < 0.01)的林分更易发病。统计模型表明，随着桦树年龄的增长，细菌湿材的几率每年增加0.36%。桦树比例在70%以上的林分，其侵染率比桦树比例较低的林分低15.3%。低放养林分的病树分布比例比高放养林分的病树分布比例高7.5%。最脆弱的是更大、更老、树皮有纵向裂缝、生长在较贫瘠土壤上、经常遭受水分胁迫的钟摆白杨。白桦与蕨菜和桃金娘联合感染的风险较高(分别为31.6%和44.3%)，而与短柄菊、棕地和普通愈伤草联合感染的风险较低。结果表明，银桦树与银杉(Tremex spp.)之间存在着较强的生态和营养联系，特别是与褐角银杉(Tremex fuscicornis)之间。真菌区系以小孢子根霉、粘毛霉、金黄色青霉、紫红色青霉和狭窄顶孢青霉为代表。从桦木细菌湿木中分离出肠杆菌、黄单胞菌、泛菌和芽孢杆菌。通过人工感染，发现气压肠杆菌为主要病原体，其他细菌为弱致病菌或伴发。nimipressuralis在桦树树皮和形成层中形成的菌落形成单位(CFU)最多，分别为164个和127个，在健康桦树的自生微生物群中也发现了少量的必需菌。

The paper presents the history of the protection of trees with special values, the current state of monument trees and the preliminary description of trees meeting the minimal circumference criteria to be regarded as natural monuments in the Kampinos National Park (KNP). The study was conducted in the years 2017–2019. In the KNP, there are 69 living trees with a status of natural monuments. Most of them are oaks – 56 specimens, Scots pine – 6 specimens, small-leaved lime – 5 specimens and European hornbeam and European ash – 1 specimen each. Among all, 27 trees grow individually and the other 42 grow in 7 groups. About 200 trees were recognised as meeting the minimal circumference criteria to be regarded as natural monuments. The thickest size tree in the KNP is the black poplar with a circumference of 805 cm, growing in the enclave of Ruska Kępa, and the thickest monument tree in the KNP area is Dąb Kobędzy (Kobendza Oak) with a circumference of 582 cm. Almost a half of the living monument trees (34 specimens) are situated in Kampinos Forest District. In Kromnów, there are 20, and in Laski Forest District 15 specimens of monument trees are mapped. Living monument trees were found in 15 (out of 17) forest subdistricts. The highest number of monument trees was found in Rózin Forest Subdistrict (16) and in Wilków Forest Subdistrict (10). The lowest number – one specimen per forest subdistrict – was found in six forest subdistricts (Dąbrówka, Grabina, Janówek, Krzywa Góra, Rybitew and Zamczysko). In total, there are around 300 specimens of natural monuments and trees meeting the minimal circumference criteria to be regarded as natural monuments, which means that there is one tree of this category for each 125 ha surface of the KNP.

Economic viability of forestry is one of the key pillars of sustainable forest management and a basis for maintaining forests and their multiple benefits for the society. It may be achieved by, inter alia, diversification of sources of income in forest management. The aim of the article is to analyse sources of revenues of state-owned forest enterprises (holdings) in selected European countries and ongoing changes in this respect in recent years. In the paper, we analyse the structure of revenues of state forest enterprises in Poland, Germany (with the examples of Bavaria and Lower Saxony) and Austria; however, particular attention is paid to the State Forests National Forest Holding in Poland, which is the largest state-owned forest holding in the European Union (EU) in terms of area of forests. The study is based on document content analysis methodology (desk research), including annual reports published by forest enterprises, statistical data and also legal regulations. The analysis shows that while revenues from the sale of wood are the main source of income of forest enterprises, some of them are seeking to diversify their sources of revenues. The Austrian Federal Forests can serve as an example of a good development strategy based on diversified sources of income. Also, the Lower Saxony State Forest company, which is approximately 60% dependent on the sale of wood, undertakes other activities, including real estate management, hunting and recreational services. Our study shows that both the State Forests National Forest Holding and the Bavarian State Forests Enterprise are based on timber harvest and sale to a large extent. We conclude that as regards the State Forests Holding in Poland, the possibility of expanding and diversifying commercial activities should become a subject of discussion among foresters, decision makers and politicians.

Since the plus trees are selected based on phenotype, it is necessary to evaluate them in progeny test. The aim of this study is an indication of selecting elite mother trees based on the results from half-sib progeny test trials. As study sites, two Scots pine half-sib progeny tests were selected. During evaluation, the progenies had reached the age of 38 and 40 years, respectively. In both progeny trials, quantitative parameters and qualitative traits of Scots pine half-sib progenies were investigated. Based on these data, complex evaluation of half-sib families was carried out. We concluded that, Scots pine progenies at the age of 38 and 40 years in fresh and moist mixed forests are characterised by acceptable quality, with the survival being 25%–33% per progeny test trial. Based on a complex evaluation of 38- and 40-year-old half-sib progenies of plus trees, we proposed to select 31% of tested plus/mother trees as candidates for elite trees. Further, the list of candidates for elite trees was created with five plus trees from the Volyn region (26% of the total tested from the region) and four plus trees from the Lviv region (40% of the total tested from the region). With age, the share of the best and undesirable trees decreases, while the proportion of intermediate trees increases in both control trees and half-sib progenies. At the age of 38 and 40 years, the proportion of fast-growing offspring was from 0% to 36%, while the declining trend that was observed in previous years was being continued. Thus, due to the declining trend in the proportion of fast-growing offspring observed at the age of 38 and 40 years, we propose to select candidate trees for an elite group not early than after 40 years of test their progenies.

Mountain forests constitute one of the most diverse ecosystems, not only in Europe but also all over the world. Mountain ranges, which frequently encompass multiple countries, constitute a unique link between various natural areas, which are very often completely different from the historical point, or which are characterized by different use and management types. Although the role of mountain forests is relatively well recognized nowadays, in the distant past, these areas were poorly penetrated, mainly due to the unfavourable climate and natural topography, which discouraged not only from settling down but also from moving around. Despite the fact that mountains had been the object of interest of mining, weaving, and glassmaking industries for hundreds of years, dramatic changes in the stands in these areas were sealed by the industrial revolution in the 18th and 19th centuries. The purpose of this paper is the analysis of forest dieback process in the mountain ranges of Sudetes and Western Carpathians placed in Poland. Stress factors have been divided into three main groups, however, it should be remembered that it is a very simplified division and some factors could be partially found in the anthropogenic, as well as biotic, and even abiotic factor groups. Neither the beginning nor the end of deforestation process was defined precisely in the study, which was deliberate in taking into account constant changes in the ecosystems. Generally, three periods may be distinguished here, regarding the spruce forests dieback process. Typically anthropogenic deforestation, caused by the industrialization of the areas during the industrial revolution and earlier, deforestation in the years 1970–1980 and partially before the year 2000 (Western Carpathians) caused by a set of various stress factors and the latest period, that is, generally understood climate change. The last several years have particularly contributed to the expansion of detailed knowledge about the dependencies and the influence of abiotic, biotic, and anthropogenic factors on the health condition of spruce trees. Although models have already been developed, which describe the course of insect outbreaks, the growth and health condition of spruces, or climate factors, no model has been developed so far that would allow to depict the process of hitherto deforestation, and to enable modelling the forthcoming changes. It seems that the development of such tool, not only from the forest management point of view, would constitute a milestone on the way to precision forestry.

Abstract Vegetation serves as a universal filter that is capable of protecting the environment from pollution by industrial emissions given the availability of appropriate technical facilities. The aim of this study is to determine the ability of leaves of various species of woody plants growing in the area of sanitary protection zones to accumulate fluorine and to establish the most informative indicators of environmental pollution by its compounds. The object of the study was the species of woody plants growing in the area of protective plantations of a number of enterprises of Zaporizhzhya: Zaporizhzhya Titanium & Magnesium Combine, Zaporizhzhya Aluminium Plant PJSC, Zaporizhzhya Abrasive Plant PJSC, Zaporizhstal PJSC, ‘Zaporizhcoke’ PJSC (KOKS), Zaporizhzhya Ferroalloy Plant PJSC, Zaporizhvohnetryv (‘Vohnetryv’) PJSC, PrJSC ‘Ukrgrafit’ and Zaporizhtransformator PJSC. Under the conditions of sanitary protection zones of enterprises the leaves of woody plants accumulate significantly more fluoride compared to the control specimens. We have established that a gradual accumulation of the element occurs during the vegetation period being the most intense in young leaves. In senescent leaves, the activity of its accumulation begins to diminish. The maximum amount of fluoride was detected by us at the end of the vegetation period. Its highest concentration was found in the leaves of woody plants growing in the forest belt near the Zaporizhzhya Aluminium Plant. According to the level of accumulation of the said phytotoxicant in the leaves of plants growing in the area of sanitary protection zones, industrial enterprises of Zaporizhzhya may be ranked as follows: Zaporizhzhya Aluminium Plant PJSC > Zaporizhzhya Ferroalloy Plant PJSC ≥ ‘Zaporizhcoke’ PJSC > Zaporizhstal PJSC > Zaporizhvohnetryv (‘Vohnetryv’) PJSC > ‘Ukrgrafit’ PJSC> Zaporizhzhya Abrasive Plant PJSC > Zaporizhzhya Titanium & Magnesium Combine > Zaporizhtransformator PJSC. The largest amount of fluorine accumulated by the leaves can be attributed to such tree species as: Catalpa bignonioides, Ailanthus altissima, Acer platanoides, Populus nigra, Armeniaca vulgaris, Tilia cordata, Acer pseudoplatanus, Platanus orientalis, which is a distinguishing characteristic of the sanitary protection zones of various enterprises in the city of Zaporizhzhya. Variations of fluorine accumulation in different experimental plots for the same species of woody plants are expressed in quantitative terms. These plants are capable of being the most efficient at purifying the atmospheric air from gaseous fluoride compounds. The highest coefficient of relative accumulation of fluorine in the leaves is found in the following species of woody plants: Catalpa bignonioides, Ailan-thus altissima, Acer platanoides, Populus nigra, Armeniaca vulgaris, Tilia cordata, Acer pseudoplatanus, Platanus orientalis, thus they have a potential to be considered for use as phytoindicators of environmental pollution by the fluorine c

Abstract This paper describes the quantitative and qualitative composition of bacteria isolated from soil in the selected sites in the Nida Basin, in places where mycorrhizae and ascocarps of summer truffle (Tuber aestivum) were found, and in a control soil (without truffle). A classic growth culture method was used with Sanger DNA sequencing to obtain quantitative and qualitative measures of bacterial cultures. The obtained results showed differences in bacteriome composition between the case samples, in which summer truffle fructification was observed, and the control samples. Seven classes of bacteria were identified: Actinobacteria, Bacilli, Deinococci, Flavobacteria, Alphaproteobacteria, Betaproteobacteria, and Gammaproteobacteria. The most numerous bacterial genera were Pseudomonas (class Gammaproteobacteria) – 33%, Streptomyces (class Actinobacteria) – 29% and Bacillus (class Bacilli) – 15%. This research broadens the understanding of individual groups of bacteria accompanying truffles and their potential impact on the formation of summer truffle ascocarps.

Abstract Evolutionary processes lead to the survival of individuals best adapted to local environment. This gives rise to allele polymorphism and genetic diversity of populations. Isoenzyme proteins, which are the product of gene expression, are an effective tool for tracking these changes. On the other hand, the reproductive potential of a given population can be assessed based on its ability to produce viable and efficiently germinating seeds. The present results combine molecular analyses of isoenzyme proteins with anatomical and morphological studies of Scots pine seeds (Pinus sylvestris L.). The study was conducted in 6 populations that are characteristic of this species occurrence range in the country. The results confirm the correlation between seed weight and embryo size. They also show a population from northeastern Poland had a higher effective number of alleles and seed with lower germinative energy and capacity. There was genetic homogeneity in all except for the population from Woziwoda, which was significantly different based on the Fst test. The genetic characteristics of Scots pine from Woziwoda may be associated with the lower levels of rainfall that occur there during the growing season. The results improve our knowledge of Scots pine variability and contribute to the discussion of the impact of local environment on genetic variability.
