Opis:
Characteristic features of European woodland include both a reduction in natural forest areas and an increase in former agricultural areas occupied by secondary woodland. The management of these areas is challenging in terms of nature conservation, agricultural and forestry management and policy. The aim of our study was to reconstruct the history and to document the current tree stand structure for a secondary oak-beech woodland in Hungary. Towards the end of the 1800s, this area which was once almost completely occupied by a continuous forest, had been transformed into a wood-pasture. As a result of its gradual abandonment, the closed forest stand of the pasture increased from 10 to 52% between 1963 and 2005. The most characteristic feature of this woodland is the abundance of large trees. Globally, the number of large and ancient trees is rapidly diminishing. Therefore preserving and maintaining such areas, where large trees could live, is an essential management task.

Kora dębu korkowego, uprawianego głównie w Portugalii i w krajach zachodniej części basenu Morza Śródziemnego, jest wykorzystywana od ponad 5 tys. lat. Obecnie znajduje szerokie zastosowanie, od naturalnych korków do butelek po elementy z kompozytów w budownictwie, transporcie, a nawet przemyśle kosmicznym, jest strategicznym surowcem dla zrównoważonego rozwoju, nie tylko krajów śródziemnomorskich. W Cz. I artykułu omówiono uprawy dębów korkowych oraz strukturę chemiczną ich kory, a także makro- i mikroskopową morfologię korka naturalnego.
Cork is the bark of the cork oak tree cultivated mainly in Portugal and the Mediterranean region. As amaterial it has been used for more than 5000 years. Nowadays, it is used in multiple applications, from wine bottles to aeronautics and regarded as astrategic material for sustainable development in many countries. The first part of the presented review is focused on cultivation aspects of cork oak trees as well as morphology (at macro- and microscales) and chemical structure of suberin, the main constituent of cork. The honeycomb-like cork structure makes it one of the best natural, renewable, sustainable raw material, which is used all over the world.

Opis:
The age of old trees is often estimated only on the basis of trunk thickness. A more detailed method for estimation of the age of old oak trees is presented here, depending on species and environmental conditions. For oak trees growing singly or at forest edges, the mean annual ring width is over 2 mm, while in the forest interior ca. 1 mm for Quercus petraea, and 1.2−2.5 mm for Q. robur, depending on site fertility.

The aim of this study was to verify descriptions of the morphology of the fungus responsible for powdery mildew on oak leaves of nursery seedlings and of young trees in forest stands. Infected, fully developed leaves from apical parts of stems of Quercus robur or Q. petraea were collected in two national parks and in six forest districts in Poland. The taxonomic characteres of all specimens were generally consistent with those given in keys for Microsphaera alphitoides. However, the limoniform shape of conidia, characteristic of two sites (nurseries), has not been found in available synopses. Limoniform conidia were significantly longer and wider than others. Agreat variety of forms of mycelium on leaves were observed. The mycelium appeared in three forms: (1) floccose or felted oval patches (always with yellow or brown discoloration), (2) faveolate oval patches (often with yellow or brown discoloration), and (3) felted or mealy mycelium along veins (rarely with discoloration). Mycelium without limoniform conidia appeared in all forms, while mycelium with limoniform conidia appeared only in the form of patches, always causing leaf discoloration.

Opis:
This paper is a kind of addition to four other articles about famous Lithuanian oak−tree called 'Baublis' published in Sylwan, especially those from 1827 and 2002. The first one, written by Dionizy Paszkiewicz was a description of its cut down in 1812. The latter was a scientific estimation of 'Baublis'es' main parameters (trunk circumference, height, volume, age, etc.) basing on facts from the previous article. However, some new data about this tree were found basing on the parameters of unique building made from its trunk that had survived on Lithuania since the beginning of 1880s. The new estimations of this famous oak−tree size are presented.

Opis:
Alternative methods of oak cultivation aim at reducing the cost of establishment of young plantations and decrease in the expenditure on their tending. In these methods, the corridors consisting of oak seedlings planted in the rows or isolated groups of twenty six seedlings are enclosed by stripes or patches without intervention left for natural succession. The restriction in site preparation on these areas and spontaneous development of young generation of trees are assumed to create favourable conditions for many forest organisms and, in results, significantly improve biological diversity of the managed forests. The aim of the study was to recognize the response of forest collembolan assemblages on alternative methods of establishment of oak plantations. The study was performed in the Forest Experimental Station in Rogów (Central Poland). In a mature stand on moderately humid mixed deciduous forest site, on clear−cut and on oak young plantations made by corridor and tree groups methods, fifteen study plots were established. In case of young plantations, these plots encompassed both artificially planted corridors or tree groups and adjacent fragments of plantation left for natural succession. Soil samples were taken in June and September 2014 and, using a simplified Tullgren apparatus, 18 thousands of collembolan specimens belonging to 84 taxa were identified. Our study proved that clear−cut and site preparation by rotary tiller on moderately humid mixed deciduous forest had a negative impact on Collembola assemblages, because caused a reduction in species number and abundance. However, the establishment of oak plantations by alternative methods, consisting in abandonment an artificial planting on some patches of renewed plots, significantly mitigate negative effects of clear−cut and reforestation on collembolan assemblages. The species number and abundance of springtails on patches left for spontaneous succession were distinctly higher than in artificially planted corridors or groups of trees in case of all studied plantations. Furthermore, it seems that corridor method in oak plantations establishment is advantageous for forest springtails, because the number of specimens per square meter on corridor plantation was higher than in tree group method. The beneficial effect on soil fauna of alternative methods of oak cultivation described in this paper weighs in favour of their wider application in silviculture.

Opis:
Climatic parameters are the main environmental factors affecting tree growth. The main aim of the presented study was to determine whether different oak species growing under contrasting environmental conditions show different sensitivity to climatic parameters. Four oak stands with Quercus robur, Quercus petraea, Quercus polycarpa and Quercus dalechampii growing in the same area were evaluated. Standard dendrochronological methods were used for sample preparation, ring width measurements, cross-dating, chronology development, and the assessment of growth-climate response patterns. Although the species grew under different environmental conditions, their local tree-ring chronologies are highly correlated. The radial growth responses to climatic parameters differ slightly, but the response depends more on local site conditions than on the oak species. At the same time, the strongest correlations between radial growth and climatic parameters were identical among species and sites. The amount of water available in the soil was the main climate-dependent factor limiting radial growth. Approximately since the 1990s, the distribution of rainfalls within the growing season has changed at the expense of spring precipitation. The significance of relative soil moisture content during spring for oak growth increased and the significance of summer values decreased.

Opis:
The studied Quercus robur trees were oaks protected as monuments of nature (200-350 years old) and oaks growing in forest stands (200-300 years old). The most visible symptoms occurring in aboveground organs included defoliation (25-75%), dying of twigs and branches. Discoloured heartwood, obtained with an 80-cm Pressler borer, differed in colour intensity from normal wood and was divided into two groups: stained brown and dark brown. The brown-stained heartwood was a more active site, considering the number of fungi and their ability to produce enzymes (phenoloxidase, pectinase and cellulase) in comparison with the dark-brown-stained heartwood. This brown-stained heartwood contained also statistically more Ca, Mg and Mn.

Opis:
The ability of spatial expansion and conquering of new locations, suitable for growth, is one of the most important properties enabling different plant species (including forest trees) a permanent existence in a constantly changing (in space and in time) environment. In the course of evolution, plants developed several adaptations and mechanisms enabling them to capture new localities appropriate for life. The key role in this process is played by so called propagules, i.e. differently built spores, seeds and fruits. The main sources of forces and major transportation vectors for propagules are such mechanisms as: power of gravity (barochory), wind (anemochory), water (hydrochory), animals (zoochory) and man (antropochory). Among them, in case of tree species producing large seeds, containing bulky amounts of food resources, the most important role is played by zoochory. The special variant of zoochory is ornitochory, i.e. dispersion of plant propagules by birds. One of the best known and documented examples of ornitochory is dispersal of oak acorns by jays (Garrulus glandarius). The contemporary research shows that during a vegetation period one single bird is able to deposit even several thousends of acorns within the area of 10 to 100 ha. The dispersal distance in case of acorns distributed by jays is variable and depends on several factors, first of all, climatic conditions and degree of environmental heterogeneity. On average, acorns are distributed within a distance of several hundred meters from seed trees; sometimes they are disseminated at a distance of several (4−8, maximum 20) kilometers. As a rule, only a part of deposited acorns is uncovered and consumed by birds, thus at least some of them can germinate and produce new oak seedlings. It was also recently demonstrated that jays preferably put down acorns under the stand canopies composed by tree species other than oak, for instance, under Scots pine trees. Under favourable conditions, this initiates natural successional processes and leads to a significant conversion of tree stand composition. Considering a large scale and commonness of this phenomenon, it deserves an interest and attention, not in the case of natural forests only, but in the case of managed forests as well, in which the quasi−natural, successional processes, initiated by jays, can considerably contribute to a greater compositional and structural diversity of tree stands.

Opis:
Climate change has a significant impact on natural ecosystems, particularly on floodplain forests that are among the most transformed ecosystems in the world. The climate sensitivity of dominant species is likely to play a key role in determining the susceptibility of flooded forests to climate changes. Here, we use dendrochronological approaches and local climate records from 1880 to 2015 to assess the response in pedunculate oak (Quercus robur L.) trees growing in a floodplain of the Dnipro River near Kyiv to climatic variables. Correlation analysis reveals the strongest positive association of the Q. robur tree-ring width chronology with May–June precipitation, May–June temperature, and May self-calibrating Palmers drought severity indices (scPDSI). The moving-window correlation analysis points to positive association with the scPDSI after the 1950s, when local river regulation was implemented. The positive correlation with current March precipitation is the least expected change in the oak growth-to-climate relationship that occurred in the aftermath of human alterations in the local river and regional climate changes. This study discusses the probable ecological consequences and ecophysiological mechanisms of observable climate-to-growth relationships and their temporal stability.

The study presents results of dendrochronological analyses of Scots pine (162 trees) and English oak (97 trees) from 13 research plots located in NE Poland. The investigations resulted in construction of local chronologies (six for oak and seven for pine), which in turn enabled to define new regional chronologies; 2_NE_PL for pine, covering the period 1738−2003 AD, and Q_NE_PL for oak, 308−year long (1696−2003 AD). The elaborated chronologies allow for absolute dating of wood and yield new data on the extent of dendrochronological signal.

Opis:
Oaks have often been depicted in scientific and popular literature primarily for their size, as well as cultural and historical value. Such studies usually concerned the most impressive specimens on a national scale. However, often there is little data on the largest specimens on a local scale. The study carried out between 2020-2021 in Gryfino County was an attempt to fill this gap. The study was conducted on a group of trees that are thickest in terms of diameter at breast height. The analysis included a detailed description of dendrological parameters and an assessment of health according to the scales used in modern dendrology. Information from historical sources was also taken into account.
