Opis:
The influence of slope exposure and altitude on the height of trees in the stands of the Carpathian beech forest Dentario glandulosae-Fagetum in the lower montane zone in the Bieszczady National Park. The aim of the study was to investigate the influence of slope exposure and elevation above sea level on the average height of trees in the stands of the Carpathian beech forest Dentario Glandulosae-Fagetum in the lower montane zone of the Bieszczady National Park. The research material consisted of measurements made as part of a grid of permanent research plots of the Bieszczady National Park with a size of 4 ares, arranged in a grid of squares with a spacing of 500 x 500 m. Using a two-factor analysis of variance, the average height of beech trees in two height zones (600-800 and 800-1000 m above sea level) and at two slope exposures (north and south) were compared. The influence of the interaction between the two factors was also studied. The height of beech stands was mainly determined by the altitude and the interaction between the exposure of the slope and the altitude. It was not found that the exposure of the slope significantly differentiated the average heights of beech trees in the lower montane zone in the Bieszczady National Park.
Wpływ ekspozycji stoku i wysokości nad poziomem morza na wysokość drzew w drzewostanach buczyny karpackiej Dentario Glandulosae - Fagetum w reglu dolnym na terenie Bieszczadzkiego Parku Narodowego. Celem pracy było zbadanie wpływu ekspozycji stoku oraz wysokości nad poziomem morza na średnie wysokości drzew w drzewostanach buczyny karpackiej Dentario Glandulosae - Fagetum w reglu dolnym na terenie Bieszczadzkiego Parku Narodowego. Materiał badawczy stanowiły pomiary wykonane w ramach siatki stałych powierzchni badawczych Bieszczadzkiego Parku Narodowego o wielkości 4 arów, rozmieszczonych w siatce kwadratów o więźbie 500 x 500 m. Za pomocą dwuczynnikowej analizy wariancji porównano średnią wysokość buków w dwóch strefach wysokości (600-800 i 800-1000 m n.p.m.) oraz przy dwóch ekspozycjach stoku (północnym i południowym). Zbadano również wpływ interakcji między tymi dwoma czynnikami. Wysokość drzewostanów bukowych była determinowana głównie przez wysokość n.p.m. oraz interakcje między eskpozycją stoku a wysokością nad poziomem morza. Nie stwierdzono by ekspozycja stoku istotnie różnicowała średnie wysokości buków w reglu dolnym w Bieszczadzkim Parku Narodowym.

Opis:
Productive European beech stands (Fagus sylvatica L.) involving Scots pine (Pinus sylvestris L.) are formed in Ukrainian Roztochie. Considering value and limited distribution of beech stands involving pine in tree species composition, it is necessary to work out and implement measures for their natural restoration in connection with the climate change and the efficient use of raw materials and non-wood products. Main forestry and management indices of beech stands that include pine in tree species composition were analysed. Forestry activities that are currently carried out in middle-aged and maturing stands significantly reduce their relative completeness and growing stocks, as determined by comparing growth particularities of productive beech stands from different sources.

Opis:
As of 2019, the total area of forest stands with the varying proportion of Scots pine (Pinus sylvestris L.) and beech (Fagus sylvatica L.) in composition on the Ukrainian Roztochchia was 11,251.3 ha and the area of pine stands involving European beech in composition was 6879.5 ha. Pine stands involving beech in composition are formed on the fresh, moist and boggy relatively pure and relatively rich soil condition. Pine forest stands (average share of pine exceeds 56%), which include beech in composition occupy more than 80% of the total area of interest. Mature and overmature forest stands dominate most of the landscape. More than 85% of stands are characterized by an average relative completeness. Undergrowth of deciduous tree species, which is mainly formed by European beech or hornbeam (Carpinus betulus L.) and rarely by common oak (Quercus robur L.) or sycamore maple (Acer pseudoplatanus), is available under a canopy of middle-aged, ripening and mature stands. The study points to the need to rethink forest management approaches and eventually to use such methods of forest cuttings that ensure natural regeneration not only of a European beech and common oak, but primarily of a pine. The practice of creating pine plantations in such conditions favourable for its growth and development should be used only in those cases when it is impossible to achieve natural regeneration of pine.

Opis:
Puszcza Bukowa pod Szczecinem stanowi niezwykle cenny pod względem przyrodniczym i historycznym obszar, na którym w roku 1991 ustanowiono Szczeciński Park Krajobrazowy „Puszcza Bukowa”. Na jego terenie i w otulinie można spotkać sędziwe okazy drzew, które ze względu na swoje rozmiary, a niekiedy także okoliczności posadzenia, stanowią istotny element dziedzictwa przyrodniczego i historycznego tego terenu. W latach 2017–2018 przebadano dwanaście historycznych drzew – osiem egzemplarzy dębu szypułkowego (Quercus robur) oraz po jednym: lipy drobnolistnej (Tilia cordata), holenderskiej (T. ×europaea), szerokolistnej (T. platyphyllos) i cisa pospolitego (Taxus baccata). Przeprowadzono szczegółową analizę źródeł historycznych zawierających informacje o badanych drzewach, opisano ich parametry dendrologiczne oraz oceniono stan zdrowotny według skal stosowanych we współczesnej dendrologii. Najgrubszym okazem z badanych drzew była lipa szerokolistna nazywana Lipą św. Ottona, o obwodzie 875 cm. Stan zdrowotny większości drzew był zadowalający pomimo dużej konkurencji w drzewostanach leśnych. Poza dwoma przypadkami w pobliżu drzew nie stwierdzono tablic informacyjnych, które przedstawiałyby walory historyczne i przyrodnicze okazów.
The Beech Forest near Szczecin is an extremely valuable area in terms of nature and history, where in 1991 the Szczecin Landscape Park ‘Puszcza Bukowa’ was established. In the park and a separate protection area around it, you can find old specimens of trees, which due to their size and sometimes the circumstances of planting are an important element of the natural and historical heritage of this area. In 2017–2018, twelve historic trees were examined: eight specimens of pedunculate oak (Quercus robur), one small-leaved lime (Tilia cordata), one common lime (T. ×europaea), one large-leaved lime (T. platyphyllos) and one common yew (Taxus baccata). A detailed analysis of historical sources containing information about the examined trees, their dendrological parameters and health status according to scales used in modern dendrology was carried out. The thickest specimen among the examined trees was the large-leaved lime called the Linden of St. Otton, the circumference of which was 875 cm. The health condition of most trees was satisfactory despite the high competition in forest stands. With the exception of two specimens, in the vicinity of the trees, there were no information boards showing the historical and natural values of the specimens being the subject of the research.

Opis:
Because of their role in carbon and nutrient exchange, litterfall and leaf area have been increas- ingly studied in the last few decades. However, most existing information comes from managed forests, while comparable data for virgin forests is scarce. To address this scarcity, we investigated a mixed beech – silver fir virgin forest located in the Southern Carpathian Mountains, using 78 litter traps to measure the annual litterfall production, litter composition and leaf area index (LAI). The LAI was calculated in two ways: directly, by using litter traps, and indirectly, based on hemispherical photographs. Furthermore, we investigated the influence of different stand and environmental characteristics on litter production, total foliar mass and LAIs. Annual litter productivity ranged from 1.8 to 8.3 t ha−1 with a mean of 3.5 t ha−1. Litter was composed mainly of beech leaves (66%) along with a lower percentage of silver fir needles (16%). The total foliar dry mass (sum of beech leaves and silver fir needles) increased significantly with the proportion of beeches and decreased with the median stand age. The LAI determined by using litter traps had a mean value of 5.06 m2 m−2, ranging from 3.52 to 8.22, and was characterised by a higher variability than the LAI estimated indirectly using the hemispherical approach (which had a mean value of 3.65 and a range of 2.30–5.28). The two indices did not correlate with each other. We found no significant relation between the LAIs and any stand or environmental variables. We conclude that in the more complex forests, such as the virgin beech – silver fir mixed forest we studied, annual foliar dry mass is more closely related to stand characteristics than is LAI. We also note significant limitations of both LAI estimation methods, which indicate that a more elaborate approach to estimating LAI is needed.

Opis:
This study investigates the effect of the enrichment of Scots pine stands with a common beech understorey on changes in the species composition and selected life traits of an important zooindicator group, such as the ground beetles (Col. Carabidae). The field investigations were carried out in a fresh coniferous forest in the Myszyniec Forest District (N Poland) in stands with (P+) and without (P) beech in the understorey. Each treatment was repeated four times. In each repetition, six pitfalls were installed. The traps were replaced 13 times, every two weeks, from April to October. In total, 4412 specimens classified into 25 species of ground beetles were captured. The tree stands with the beech understorey were observed to contain a significantly higher number of species than the ones with the beech undergrowth. Also, the value of the Shannon index of species diversity (H’) and mean individual biomass (MIB) were significantly higher in the treatment with the beech understorey. Principal Component Analysis showed variations in Carabidae assemblages within the analysed types of forest. Pterostichus oblongopunctatus, Pterostichus aethiops and Pterostichus vernalis were more strongly correlated with the stands without beech understorey. The stands enriched with the beech understorey correlated with the occurrence of large zoophages: Carabus arvensis and Cychrus caraboides, and hemizoophages of the genus Amara. An in−depth ecological characterisation of the captured Carabidae showed that the dominant ground beetles in the investigated forest habitats, in terms of the number of caught individuals and species, belonged to forest zoophagous carabids characterised by moderate requirements for moisture in a habitat, and having the spring type of development. Representatives of large zoophages and species with the autumn type of development, i.e. species associated with later ecological succession stages, were more numerously caught in the pine stands without the beech understorey The study provides evidence that justifies the planting of deciduous undergowth in monoculture coniferous pine tree forests. The presence of an understorey contributes to higher: richness of Carabidae species, values of the MIB and abundance of large forest species presenting the autumn type of development, that is the species, which are characteristic for forest areas representing a highly advanced succession stage.

This paper presents results on the restoration of Scots pine stands established on post-agricultural lands undergoing conversion into mixed stands. Sessile oak (Quercus petraea), common beech (Fagus sylvatica) and small-leaved lime (Tilia cordata) seedlings were planted in artificially created gaps (0,02 ha to 0,05 ha each) cut in six experimental plots (Forest Districts: Bielsk, Krynki, Sobibór, Dobieszyn, Skrwilno and Łupawa) located in 20–25-years-old pine stands. The experimental plots were spread across northern, central and eastern Poland and affected by root-rot fungus (Heterobasidion annosum). Nine years after planting, the number of individual trees and shrub species, their height sum and average height were calculated for fenced artificial gaps (LSO) as well as non-fenced artificial gaps (LSN) and compared to natural gaps (LN) and non-disturbed neighboring stands (D). Results were calculated separately for the planted species (oak, lime and beech) but combined for all other species. The results indicate satisfactory restoration in all of the investigated plots except in Krynki, which is located in a relatively poor site. Significant differences appeared between height sum as well as average height of planted species in fenced compared to non-fenced gaps. Furthermore, in both, natural and artificial gaps, the species composition of the young generation was enriched with natural regeneration of pioneer species, mainly silver birch (Betula pendula), rowan (Sorbus aucuparia) and aspen (Populus tremula).

Opis:
This paper presents the genetic variability in the growth parameters and morphological traits, as well as the silvicultural quality of progeny of 23 European beech (Fagus sylvatica L.) provenances from south−eastern Poland. The research was conducted on the experimental plot established in the Łosie Forest District in spring 2006. After 10 years, during the spring and autumn, we determined and measured the spring phenology and survival rate, the diameter at breast height (dbh), the tree height, and the straightness of trunk. The results obtained point out the considerable variability of analysed features, both within and between different beech populations (tab.). Highest and lowest survival rates are noted for the beeches from Lutowiska and Leżajsk (populations 451 and 461), respectively (fig. 2). Lowest mean height and dbh were achieved by beeches from Bircza (453), while the tallest and broadest trees were from the Kielce population (390) (fig. 3−4). The overall silvicultural assessment based on survival, height, dbh, spring phenological phases and straightness of the trunk revealed that the most valuable populations of beech are those originating from Kielce (390), Bircza (454), Strzyżów (459), Lesko (452), Rymanów (457) and Lutowiska (451). In turn, the analysis resulted in least favourable assessments for beeches from Bircza (453) and Gromnik (362). Thus, we confirmed also that trees of local origin are not always best−adapted to (and do not always grow best in) the place they originate from. The obtained results are highly relevant from the principles of creating the seed source regions for beech in Poland, as the proper selection of a population for the given place of growth may yield benefits for forest ecology and management.

Opis:
The study objective was to verify the hypothesis on ecotypic variation in beech and ineffectiveness of transferring its reproductive material over larger distances. Beech nuts were collected in the autumn of 1990. Experimental sites were established in the Baligród and Oleszyce forest districts (SE Poland). On single plots of 18.00×13.75 m (247.5 m2), a total of 110 three−years−old seedlings were planted in a 1.50×1.25 m spacing in autumn 1993. Single row of mountain ash was left between the plots. In the period of 1994−2016 a series of analyses was conducted concerning adaptation, growth, phenological and qualitative traits. Height was measured on all trees using a measuring stick, except for the year 2016, when hypsometer was used to measure approximately 20 heights and remaining ones were determined based on the height curve. Results were analysed using univariate analysis of variance based on the random model, followed by Duncan’s multiple range test for each experimental site and year of the study. For 2016 ordering of populations in each of the experimental sites was compared using Spearman’s rank correlation test. In terms of survival rates in Oleszyce site the local provenance from Oleszyce proved to be superior. In all the years of the measurements it was characterised by the highest survival rate. In this respect the Komańcza and Lutowiska provenances from the Bieszczady Mountains turned out to be the worst ones. In the experimental site in Baligród, the Barlinek and Połczyn provenances outranked the others in terms of their survival rates, while in 2016 it was the population from Komańcza. Tree height effects in Oleszyce site showed that the local population from Oleszyce grows best, while the Pomeranian population from Jamy was also exceptional. The Bieszczady populations (Komańcza and Lutowiska) are characterised by the worst growth traits. In the experimental site in Baligród, the local Baligród population is characterised by poorest growth, similarly to the other ones from the Bieszczady. In terms of growth, the Western Pomeranian population from Gryfino is exceptional. As far as all the evaluated traits are concerned the investigated populations exhibit considerable variability, as no geographic ordination could be found. It was confirmed that imported populations, even from long distances, may exceed local populations in terms of their adaptation traits and growth rates.

Opis:
Earthworms play an important role in the soil quality, including forest soils. Their presence in zooedaphone, as well as their abundance and species diversity, indicate the state of the soil profile. The species diversity of the representatives of this group of macrofauna in a beech forest in the Bieszczady Mountains is recounted in this article. Earthworms were investigated in the soil of four sites selected near Ustrzyki Górne in Carpathian Dentario glandulosae – Fagetum beech woods within the Bieszczady National Park (sites in D. g. Fagetum festucetosum, – typicum, – lunarietosum and – allietosum), every month during the annual cycle during two periods: a/ in 1986–1987 and b/ in 2009–2010. It was done according to the Zicsi’s recommendations, using the Zajonc combinated method, on each site, six 25×25×20 cm samples were extracted. The soil was divided into two layers (0–10 cm and 10–20 cm) and the earthworms were selected manually from them. From deeper layers, they were driven out with a weak (0.4%) formalin solution. In the 1980s, thirteen earthworm species were found (total of 1805 specimens) in the soil of four sites investigated. In a decreasing order of numbers there were: Dendrobaena alpina alpina (Rosa 1984), Allolobophora cernosvitoviana (Zicsi 1967), Aporectodea rosea rosea (Sav.,1826), Aporectodea caliginosa (Sav., 1826), Lumbricus terrestris L., 1758, Octolasium lacteum (Orley,1881), Allolobophora carpathica (Cog., 1927), Fitzingeria platyura montana (Cer., 1932), Octodrilus transpadanus (Rosa, 1884), Dendrobaena octaedra (Sav., 1826), Eisenia lucens (Waga, 1857), Lumbricus rubellus (Hoffm., 1843), Dendrodrilus rubidus tenuis (Eisen, 1874). Twenty years later, in the years 2009-2010, eleven earthworm species were found in the soil of the same four sites investigated (total of 660 specimens). There was no occurrence of L. rubellus, and O. transpadanus. For all the cited species, the vertical distribution dynamics in an annual cycle was investigated as well as the preferred soil layer in terms of soil profile. The features of the afore-mentioned earthworm species and the soil levels they prefer allowed their affiliation with the ecological groups defined by Bouche to be considered or determined. The knowledge on the association of earthworms to ecomorphological groups in natural or a slightly changed ecosystem is becoming very useful, for example at the time of the reclamation of degraded soils with Lumbricidae as bioindicators.

Opis:
Soil degradation is caused by geological, climatic and biological factors, as well as human activities. One kind of degradation involves loss of soil biodiversity as a result of global environmental changes. A study on earthworms was carried out near Ustrzyki Górne in the Bieszczady Mts (Poland), on a monthly basis, in 1986–1987 and 2009–2010 at various sites within the Carpathian beech forests (Fagetum carpaticum). During the years 1986–1987, a total of 13 species of earthworms were found: 6 species on site I, 8 species on site II, and 9 species were recorded within the site III. The highest abundance, i.e. 11 species was found on site IV. The study, which revisited the same locations in 2009–2010, identified only 10 species. In sites I, II and III, 7 earthworm species were found in each, and in site IV –10 species. The authors also investigated the factors endangering the fauna of earthworms in the Bieszczady Mountains, and following the example set by other countries which had made attempts to introduce earthworms into the red lists of the threatened species, it was proposed that such a procedure should be adopted for the endemic species O. transpadanus. It was also observed that specimens of L. terrestris had penetrated the natural areas of the National Park.

Opis:
Genetic diversity is often considered a major determinant of long term population persistence and its potential to adapt to variable environmental conditions. The ability of populations to maintain their genetic diversity across generations seems to be a major prerequisite for their sustainability, which is particularly important for keystone forest tree species. However, little is known about genetic consequences of demographic alterations occurring during natural processes of ecological succession involving changes in the species composition. Using microsatellites, we investigated genetic diversity of adult and offspring generations in beech (Fagus sylvatica L.) and oak (Quercus robur L.) populations coexisting in a naturally established old-growth forest stand, showing some symptoms of ongoing ecological succession from oak- to beech- dominated forest. In general, adult generations of both species exhibited high levels of genetic diversity (0.657 for beech; 0.821 for oak), which, however, depended on the sets of selected genetic markers. Nevertheless, several symptoms such as differences in genetic diversity indices between generations, significant levels of inbreeding (up to 0.029) and low estimates of effective population size (48–80) confirmed the declining status of the oak population. On the other hand, the uniform distribution of genetic diversity indices across generations, low levels of inbreeding (0.004), low genetic differentiation among adults and offspring and, most importantly, large estimates of effective population size (119–716), all supported beech as a successive and successful tree species in the studied forest stand.

Opis:
The study presents plant interception understood as a process of retaining rainfall over the entire surface of the plant. The objective was to collect and prepare data presenting changes in the amount of rainwater reaching the forest floor, and to inference on the diversity of water capacity within canopy of a single tree. A characteristic feature of an interceptive tank is the lack of tightness, which provides the possibility for the determination of horizontal distribution of water that reaches the forest floor. The amount of throughfall depends on direct rainfall and humidity, while its spatial distribution depends on the structure and species composition, the shape of crowns, the degree of compaction of foliage in the crowns and the distance from the tree trunk. Increase in rainfall was reported at specified time points, which, in combination with the distribution of rain gauges in the square grid, provided spatio−temporal image describing changes of water capacity of the treetops. Single tree and biogroups influence the specific mosaic of soil properties that change even on a small scale. This kind of interaction is somewhat important for the stand regeneration. The studies were carried out in Węgierska Górka Forest District (southern Poland). Changes in the amount of rainwater reaching the forest floor after successive time points during 47 individual rainfall events were controlled. Spatio−temporal distribution of rainfall was related to the distance from the trunk, but primarily to the construction of the treetop. As a result, the graphic interpolation of spatial data describing the amount of water retained in the treetop after a single rainfall was provided. The distance from the trunk, the branch system and construction of the treetop significantly affected the amount of water reaching the forest floor. The morphology of the treetop and root system, as well as the characteristics of beech trunk are causes, and simultaneously, consequences of penetration of rainfall into the forest floor that is characteristic for this species. The increasing attention is paid to determine the spatial variability of studied phenomena, which is a kind of physical−mathematical model, which takes into account the local variation of the analyzed traits.
