    Opis:
    Results of the investigations of spatial and temporal differentiations of Apoidea in the forests of Wielkopolski National Park were presented. It was shown that the both forest floor differ with the degree of species differentiation and domination’s structure and total number of bees. In the herbaceous layer of the forests about twice as many spedes were found than in the crowns. Also the Shannon-Weaver’s indices for bees communities of the herbs layer are higher in all three investigated forest ecosystems. The curves of Apoidea numbers in tree crowns and forest floor were similar. The curves of Apoidea numbers in the deciduous forests have one peak in the first days of May. Whereas the curves of Apoidea numbers in the pine forest have multi peak course. It was proved that trees play an important role in feeding chain of bees inhabiting deciduous forests.

    Opis:
    Continuation of the mycological study of the fire-damaged pine forest in Kampinos National Park in central Poland in 2017 produced interesting new findings. Among the taxa collected, 36 were new to the park, six had not been hitherto reported from Poland (Calycellina araneocincta, Ciliolarina aff. laetifica, Clitocybe metachroides, Galerina cerina f. longicystis, Parasola cuniculorum, Pleonectria pinicola), and the previous status of one taxon (Pleonectria cucurbitula) had been uncertain. Short descriptions based on collected specimens have been prepared for all taxa new to Poland. The current number of taxa of macromycetes identified in Kampinos National Park has reached 1,604.

    Pine wilt disease caused by pine wood nematodes is endemic to North America. Pine wood nematodes have already spread to East Asia, including China, Taiwan and Korea in addition to Japan. The pine wood nematode, Bursaphelenchus xylophilus, was discovered in Portuguese pine forests in 1999. If it were to become established in the pine forests in Europe, it could become one of the most serious threat to coniferous forests worldwide.

    Opis:
    The studies were carried out in 2019 on the territory of the landscape reserve Grodnenskaya Pushcha (Grodno region, Belarus) in which 26 natural and artificial communities of pine forests with mosses (Pinetum pleuroziosum) were studied on a age range from 5 to 113 years, using the trial plot method (400 m 2). Phytoindication of ecological regimes on the scales proposed by H. Ellenberg showed a tendency to decrease illumination, moisture, and trophy and an increase in acidity in the age range of pine forests with mosses. The ecological interpretation of the components (the Principal Component Analysis) of the studied pine forest communities showed that the main factors responsible for the formation of the time series of natural and artificial pine forests with mosses are forestry activities, illumination regime, and soil trophy.

    Opis:
    The Tomczyce nature reserve is characterized by a degenerated forest vegetation. We assume that the regeneration process was possible to launch after the establishment of the nature reserve in 1968. The vegetation of the Tomczyce forest complex was characterized for the first time by Jakubowska-Gabara (1976) whose studies were taken as a basis of our research. The phytocenoses after 40. years of protection have a greater participation of species with higher trophic and moisture requirements. The regeneration process in communities with pine trees is caused by an expansion of broad-leaved trees and shrubs. Transformation of forest vegetation causes a decrease in cover of thermophilous and heliophilous species. On the other hand, species of oak-hornbeam forests as well as anthropophytes are in expansion. Planning of the protection activities in the nature reserve needs to include these dynamic tendencies of the vegetation.

    Opis:
    The diversity of ectomycorrhizal fungi and sporocarps abundance were investigated in 2003-2005 at nine permanent study plots in a 50-year-old pine forest. Diversity of ectomycorrhizal fungi consist of 53 taxa and the majority of them belonged to the genera Cortinarius, Russula, Amanita and Tricholoma. The most frequent species, whose fruit bodies were found in each study plot, were C. cibarius, L. necator L. rufus, P. involutus, R. aeruginea, T. saponaceumand the most abundant species which made the main part of total sporocarp yield were C. cibarius and P. involutus. The lowest species richness of ectomycorrhizal fungi was in study plots with the densest cover of grasses. Maximum of species over the fruiting period was characteristic for October and for September. It was noticed that some species virtually never occurred together at the same plot (e.g. C. cibarius and H. aurantiaca), meanwhile others occurred together quite frequently (e.g. H. aurantiacaand X. badius).

    Opis:
    Structure of pine forests develops with age and becomes more complex in older stands. Key attributes of old−growth forest structure include presence of huge trees, coarse woody debris, hollow trees, trees with fungi, clearings, two or more layered structure. In total, 26 attributes show positive correlation with age. This set can be used as base for old−growthness index. Cluster analysis divided forest stands into four groups with different level of maturity. Stands older than 160 years occurred fully developed. It seams that in sustainable forestry attributes of old−growth forests can be maintained as key elements for biodiversity.

    Opis:
    W dotychczasowych badaniach wiele uwagi poświęcano wpływowi ciągów komunikacyjnych m.in. na zanieczyszczenie gleb metalami ciężkimi, utrudnioną migrację zwierząt, hałas czy synantropizację szaty roślinnej. W niniejszej pracy zbadano oddziaływanie drogi o bardzo małym natężeniu ruchu na roślinność zielną, a w szczególności na występowanie 3 gatunków roślin z rodziny wrzosowatych: wrzosu zwyczajnego, borówki czarnej i borówki brusznicy, oraz zmienność pH gleb. Obserwacje prowadzono w drzewostanach sosnowych w siedlisku boru świeżego i boru mieszanego świeżego na terenie Puszczy Noteckiej. Założono dwanaście prostopadłych do osi drogi prostokątnych powierzchni doświadczalnych – transektów. Na każdym z nich wyznaczono 3-4 działki badawcze zlokalizowane w różnej odległości od krawędzi jezdni. Na działkach przeprowadzono obserwacje roślinności i pomiary pH gleb. Uzyskane z transektów wyniki uśredniono w obrębie działek ulokowanych w tej samej odległości od drogi i porównano z innymi stosując metody statystyczne. Przy drodze próchnica leśna okazała się istotnie mniej kwaśna niż w głębi drzewostanu, obficiej występowała roślinność zielna, w tym wrzos zwyczajny, rzadziej natomiast pojawiały się borówka czarna i brusznica, których to częstość występowania istotnie rosła wraz ze zwiększaniem odległości od drogi.
    The development of the transportation network brings both benefits and threats. Much attention is paid to soil contamination with trace elements, difficulties in animal migration, noise propagation or synanthropisation of the vegetation cover. This paper deals with the effect of provincial very low-volume road No. 150 on the herbaceous vegetation cover, especially on the occurrence of 3 species of the heather family: Calluna vulgaris, Vaccinium myrtillus and V. vitis-idaea. Observations were conducted in pine stands in fresh coniferous forest and fresh mixed coniferous forest sites in the Puszcza Notecka Forest, Poland - one of the larger forest complexes in Europe. Twelve rectangular experimental sites were established perpendicular to the road axis, called belt transects. Each of them consisted of 3-4 plots located at different distances from the pavement edge. Measurements and estimations of herbaceous vegetation cover and pH soils were recorded for the each plots. Values from all belt transects were approximated within plots at the same distance from the road and then compared using statistical methods. By the road humus was a less acidic than in the depth of the tree stand, there was more abundant herbaceous vegetation, including Calluna vulgaris, but rarely appeared Vaccinium myrtillus and V. vitis-idaea whose incidence is increased with increasing distance from the road edge.

    Opis:
    A Scots pine forest, affected by the great cormorant colony, was studied by plot-based fungal survey method during the years 2010-2012 in Lithuania. Diversity and composition of fungal communities were investigated at five zones that had been influenced by different stages of breeding colony establishment: starting-point and almost abandoned cormorant colony part (zones A and B), active part (zones C and D), and the edge of the colony (zone E). The control zone G in undamaged by cormorants pine stand was assessed too. A total of 257 fungal species of ascomycetes including anamorphic fungi, basidiomycetes and zygomycetes were recorded. Seven species were registered for the first time in Lithuania. Species richness in the examined zones varied, lowest being in zones B (51 species), C (46) and D (73) and almost twice as high in the zones A and E (129 and 120, respectively). The comparison of fungal species compositions of different zones showed that their similarity was rather low (SS: 0.22–0.59). The most obvious changes in the trophic structure of fungal communities in the territory occupied by the bird colony were a strong decrease of mycorrhizal species, the presence of coprophilous fungi on forest litter, and the appearance of host-specialized fungi on alien and non-forest plants that have established in the disturbed forest.

    Opis:
    Scots pine forest are of the main economic importance to the forest management in lowland Europe. Large areas of spontaneous pine forest, including old−growths, are located on two vast dune belts of the Kampinos National Park (central Poland). These forests grow on oligotrophic sandy soils with deep groundwater level. This makes the area unique to study long−term changes in this type of pine forest communities. The aim of the work was to assess the changes in the species composition and richness of undergrowth of Scots pine forests at the beginning of the XXI century. The study was conducted on 10 permanent and 53 semi−permanent plots located within stands of Peucedano−Pinetum and Querco−Pinetum associations on both dune belts of Kampinos National Park. The fieldworks were performed in 2001 and 2002, and repeated in 2015 and 2018. Based on Ward’s cluster analysis we described five local forms of plant communities. Seven species groups were distinguished and changes in their richness assessed using one sample Wilcoxon test. Each species group included species characteristic and/or differentiating for a given set of syntaxonomical units. The results confirmed the hypothesis of gradual decrease of the total species richness. The median of species richness change was –0.308 species per year and was statistically significant. The changes were bigger within the local forms of the Querco−Pinetum association in comparison to Peucedano−Pinetum. The decrease was connected especially with dry grassland and heathland species (characteristic for syntaxons of Koelerio−Corynephoretea and Nardo−Callunetea classes) as well as with coniferous forest generalist species (characteristic for syntaxons of Vaccinio−Piceetea and Cladonio−Vaccinietalia). The results suggest that the two main processes shaping the species composition at the beginning of XXI century within pine forest located on the dune belts of Kampinos National Park may be identified as (i) fluctuation, and (ii) simplification, manifested by species richness decrease. This is probably connected with forest regeneration after past human use and disturbance.

    Opis:
    The aim of the research described in this paper is to classify groundwater level patterns in pine stands of forest fresh sites. The approach has been employed with the view to facilitate explaining interactions between physiographic characteristics and groundwater dynamics in prospective research. The methods which have been employed so far for explanation of groundwater level dynamics interactions with local physiographic conditions do not let to draw firm conclusions. The classification of groundwater dynamics patterns requires employing more sophisticated methods, because of a relatively extensive range of groundwater dynamics site-to-site variability expressed, e.g., by amplitude and cycle period. The methods of groundwater patterns classification proposed in the literature focused either on hydrogeological criteria or, if related to forest ecosystems, focused on water balance elements in forest habitats. The area selected for investigation represented typical features for the Northern European Lowland forests defined by soil and form of terrain pattern shaped by the last glacial period (Vistulian glaciation) and dominant share of Scots Pine (Pinus sylvestris L.) in stand species composition. The research period covered the 2002-2007 hydrological years. The measurement used in analysis covered 35 sites equipped with measurement wells.

    This paper presents the results of mycological observations of the Cladonio- Pinetum community in the “Bory Tucholskie” National Park in 2018. Active protection treatments have been performed to protect disappearing communities. This study was conducted using the permanent circular plot method, with each plot having an area of approximately 100 m2. Observations were also carried out using the route method outside the plots. Consequently, 71 fungal taxa were found. Among the identified species of macromycetes are Boletopsis grisea, which is on the list of protected fungi, and seven species (Boletopsis grisea, Cortinarius armeniacus, Dacrymyces capitatus, Deconica montana, Entoloma rhodocalix, Tricholoma equestre, and Tricholoma colossus) that are on the red list of macrofungi in Poland.

    Clear−cutting impacts site conditions seriously. However, in nutrient−poor sites the effects of stand removal can be minor than in nutrient−rich sites. The aim of this work was to assess whether the clear−cut can improve species diversity of ground Cladonia species, which decline has been observed in forest communities. In stands of different age classes (≤10, 11−20, 21−40, 41−60, 61−80, ≥81 years) in the Przymuszewo Forest District (northern Poland) ground Cladonia species and their cover were recorded on research plots (10×15 m). A total of 24 species were identified in the study area. There were more Cladonia species and they were more abundant in young stands (<20 years old) than in stands older than 60 years. Nine species are significantly more frequent and demonstrated high fidelity in young stands and only one was characteristic for old stands. Composition of Cladonia species depended primarily on stand age and subsequently on canopy or bryophyte cover. In nutrient−poor sites clear−cutting is favourable for Cladonia species diversity.

    Opis:
    The fallow deer is a species with a wide range of occurrence that primarily inhabits deciduous and mixed forests in Europe and North America. However, it also inhabits boreal environments that are rich in understory, fields, and meadows. Some parts of Poland have a high density of fallow deer due to human activities. Despite its extensive distribution, many aspects of this species ecology remain unexplored. Our research was performed in Osie and Dąbrowa forest districts in the Tuchola Forest (northern Poland), where the fallow deer is an introduced species. The objectives of the study was to determine the factors influencing the winter spatial distribution of the fallow deer in an environment dominated by Scots pine forests. Using the pellet−group count method, four 100 m2 circular plots (5.6−m radius) were located 100 m apart one from the other on the perimeters of 25 equally distributed 500×500 m squares (16 circles/square) within the research area. The mean density of the fallow deer pellets ranged widely across the study area (0.5–5.6 (±1.27) pellets/square). The most significant factor affecting their winter spatial distribution was distance to water. The redundancy analysis showed that in winter, fallow deer avoids the boreal forests and chooses meadows, pastures, and cultivated fields. The fallow deer in the Tuchola Forest occurred mainly along the watercourses and meadows.

    Opis:
    In agricultural area of Konin where previously no industrial activity was performed the complex of power stations combusting brown coal was built in the end of the fifties followed by the aluminium smelter which was put into operation in 1965. Both these industrial works emit considerable amounts of phytotoxic gases (F2, SO2, NO2). Aluminium smelter emits vast amount of fluorine as aluminum is produced by thermoelectrolysis of aluminum oxide in electrolyte consisting of cryolite and aluminum fluoride as well as it is a major emitter of PAHs due to carbon electrode "combustion". Because these plants did not meet technology parameters and production was poorly controlled in first period of activity harmful effects of their emission in the natural environment were observed. Beginning from the nineties intensive proecological efforts were made and intensive modernization of the plants was performed. All these activities resulted in a significant reduction of air pollutants emission. The paper presents the results of investigation carried out in the monitoring net established in Konin area. The fate of air pollutants currently emitted and deposited to the soil within a long period of the plants activity was determined. The vacuum ceramic cup lysimeters were used to assess the concentration and hazard of inorganic and organic chemicals for water - soil environment. On the basis of differences in concentration of cations and anions the rate of nitrification and acidification processes in the soil was also analysed.
    W otoczeniu Konina na obszarze typowo rolniczym, gdzie uprzednio nie prowadzono działalności przemysłowej, na początku lat pięćdziesiątych, wykorzystując węgiel brunatny z kopalni odkrywkowych uruchomiono kompleks elektrowni PAK (Pątnów, Adamów, Konin), a w roku 1966 oddano do eksploatacji Hutę Aluminium "Konin". Zakłady te emitowały znaczne ilości gazów fitotoksycznych (F2, SO2, NO2). Huta aluminium emituje duże ilości fluoru, ponieważ aluminium produkowane jest w procesie termoelektrolizy tlenku glinu w elektrolicie zawierającym kriolit i fluorek glinu, jak również jest znaczącym emiterem WWA (PAHs) powstających w wyniku "spalania" elektrod węglowych. Ze względu na to, że zakłady przemysłowe w początku swej działalności nie spełniały wymaganych parametrów technologicznych, a emisje do atmosfery gazów odlotowych były niewystarczająco kontrolowane w środowisku przyrodniczym występowały wyraźnie szkodliwe efekty. W latach dziewięćdziesiątych podjęto intensywne działania proekologiczne i modernizacyjne zakładów, które doprowadziły do znacznej redukcji emisji zanieczyszczeń powietrza. W pracy przedstawiono wyniki badań przeprowadzonych w lasach sosnowych znajdujących się w sieci monitoringowej ustanowionej na obszarze Konina. Przedstawiono poziom depozycji zanieczyszczeń do ekosystemów leśnych oraz migrację aktualnie emitowanych zanieczyszczeń i zdeponowanych w glebie w okresie długoletniej działalności zakładów. Do oceny stężeń i zagrożenia środowiska wodno-glebowego związkami organicznymi i nieorganicznymi zastosowane ceramiczne lizymetry próżniowe. Na podstawie różnic w stężeniach kationów i anionów w różnych przedziałach ekosystemu leśnego określono także natężenie procesów nitryfikacyjnych w glebie.

    Opis:
    Fires that are one of the most classic disturbance of plant communities have had a great impact on the development of Scots pine communities. Restoration of vegetation disturbed by fire in this type of community starts almost immediately after disturbance. The intensity of fire significantly influences the future composition of vascular plant species and also the rate of change. The aim of the study was to describe the effect of intensity of the surface fire on the forest floor vegetation response and to preliminary attempt to characterize the syndynamic processes occurring after the disturbance. The research was conducted in Scots pine forest Peucedano−Pinetum in the Kampinoski National Park (central Poland). We established 45 permanent study plots, including 17 not burnt (control) and 28 burnt ones. Each plot covered area of 100 m². On each plot at first we separated the areas which were not burnt, surface burnt and characterized by complete burnout of the organic horizon of the soil. Than we measured the thickness of this horizon. Additionally the volume of organic matter burnt within each plot was calculated. Vegetation was sampled using Londo scale in the year of fire (2015) and the year after (2016). We used DCA ordination and UPGMA classification methods. Recorded species were divided into forest and non−forest groups and additionally for trees and shrubs, and the others, containing dwarf shrub, herb, bryophyte and lichen species. The linear regression method was used to estimate the relationship between measured parameters, vegetation change and changes in the species richness of distinguished groups. Two processes of vegetation reaction were observed. The first was classified as regeneration and occurred within surface burnt plots. Its characteristic feature included the higher increase in forest species richness than in case of non−forest species. The other process was defined as secondary succession alike. It occurred on plots with highest burnout of soil organic matter horizon. The increase of richness of non−forest species predominated within it. The change between two processes is smooth and depends on the participation of area with complete burnout of soil organic horizon within plot. The results show, that more than one process of recovery of community can occur in the same site and it depends especially on the proportion of soil organic horizon area burnout.

    Opis:
    Based on experiment established in pine forest of Spychowo Forest District, it was proved that clearcut caused negative changes in forest springtail communities. The logging of a whole stand reduced the number of species and their abundance. The decrease in springtail abundance depended on the method of site preparation prior to afforestation. The highest reduction was recorded in logged areas where stripes had been plowed using forest reversible plough. Regressive changes in communities were also observed on harvested sites prepared by an active plough and rotary cultivator. The attempts of clearcut improvement by addition of wood chips or leaving debris piles on logged areas were evaluated on the base of the response of springtail communities. In both cases, the number of species and abundance were higher comparing to clearcut areas without logging residuals. Also residual patches of old growth left on harvested sites had positive effect on Collembola communities. Species richness and abundance observed in those paches were higher than in control mature stands.

    Opis:
    Black cherry (Prunus serotina) was planted in forests in Central Europe in the hope of producing valuable timber and after the first disappointments, in the hope of improving the soils of coniferous plantations. Nevertheless, an unequivocal evaluation of its effect on soil environment is still a controversial issue. The aim of this study was to determine a temporary fluctuation of selected soil properties in Scots pine forest dominated by black cherry. The research was carried out in Wołów Forest Division (SW Poland). Two Scots pine monocultures developed on podzol site with and without P. serotina in shrub layer, were selected for the study. Twelve research plots (10×10 m) were randomly selected on the sites. On each plot the cover of P. serotina in the shrub layer was evaluated and every three months, during single research year (November 2013 − November 2014) soil properties (total N, organic C, soil reaction) were determined in organic (O) and humus (A) horizons. Analysis of variance and PCA procedure demonstrate some significant relationships between P. serotina and soil properties in Scots pine forest. The presence of black cherry contributes to continued changes in the organic horizon expressed by increase in total N (range of average from 1.14 to 1.38%) and drop in C:N ratio (range of average from 22.86 to 25.73). Apart from the spring, increase in pH value in the organic (range of average from 4.03 to 4.58) and humus horizons (range of average from 3.59 to 4.04) was found on the site invaded by black cherry.

    Opis:
    At present, forest fire research is becoming especially relevant in Ukraine. This study examines patterns of forest fuel accumulation in pine (Pinus sylvestris L.) stands that grow in different soil conditions with different pine stand structure. To estimate the load of forest fuel of different fractions, a combined methodology was used: the weighing method and the FIREMON (fuel load estimation) method. It was found that increase in surface forest fuel loads is not directly proportional to forest stands’ age. Fractional size distribution, capacity and loads of forest fuel depend on several factors, among which the greatest role is played by forestry characteristics of the pine stand. It was determined that in the forest site conditions of type C (fairly rich soils) in Kyiv Polissya, the share of forest litter compared to pine stands that grow in poor soil conditions (A) is smaller, ranging from 41% to 76% of the total forest fuel load. The mass proportion of the duff layer varies from 15% in young forest stands to 43% in mature stands. It was established that changes in forest fuel fractions for 1, 10, 100 and 1000 hours varied insignificantly with age rate. The share of substratum woody debris of 10 and 100 hours was insignificant and depended more on the forestry treatment regime on these sites. The mass proportion of coarse woody debris (1000 hours) was also insignificant, varying from 0% to 5.9% of the total load of surface fuel.

    This paper presents the edge effect of a very low-volume road on the belt of roadside vegetation in the “Puszcza Notecka”, Poland - one of the largest compact forest complexes in Europe. The observations were carried out in the vicinity of pine stands in the fresh coniferous forest and fresh mixed coniferous forest sites. Twelve rectangular experimental sites 30 and 50 meters wide at a distance of 0 to 10 meters from the edge surfaces were established. 75 species characteristic for the 13 phytosociological classes and 20 species associated devoided of the diagnostic value were recognized in the roadside area. Native species dominated, where the most numerous species belonged to meadow communities (Molinio-Arrhenatheretea) and ruderal (Artemisietea vulgaris). Despite the significant participation of synanthropic plants, there was no invasion of alien species.

    Opis:
    Effects of Scots pine wood amendment on the fungal community in forest soil infested with cockchafers and foraged or non-foraged by wild boars and hares were investigated. We hypothesized that sawdust amendment would increase the abundance of entomopathogenic and insect-associated species effective in cockchafer predation. The soil dilution method and morphotyping were used for fungal isolation and identification in order to quantify and qualify the viable components of the microbiota that are important for evaluating soil functions. There was usually increased abundance and decreased diversity of soil fungi one year after sawdust amendment. Application of pine sawdust more often increased than decreased the abundance of some insect-associated fungi or dermatophytes and keratinophilic species and decreased the number of cockchafer larvae. Abundance of Geomyces pannorum, Mortierella spp. + M. luteus, Pseudogymnoascus roseus, Tolypocladium inflatum and Trichoderma koningii increased, at least locally, whilst Chrysosporium merdarium, Penicillium spp. (including the most common P. citrinum, P. daleae and P. janczewskii), Sporothrix schenckii and Trichoderma spp. decreased. Application of pine sawdust under roots of 1-year-old Scots pine seedlings significantly increased the abundance of Phoma + Pyrenochaeta spp. in neighbouring soil, thus increasing the risk from Phoma blight. Trichoderma strigosum was among the dominants (frequency >5%). Another six and two Trichoderma species were among the subdominants (frequency 1–5%) and subrecedents (frequency <1%), respectively. Dermatophytes, coprophilous and keratinophilic species, e.g. Cephalotrichum, Chrysosporium merdarium or S. schenckii, occurred only or mostly in foraged plots. The altered communities resulting from pine sawdust amendment may contribute to biological control of the cockchafer larvae.

    Opis:
    The illumination under the canopy in different types of pine and spruce forests is considered. The research was carried out in different points of the Northern taiga of the Arkhangelsk region. Illumination was measured using a luxmeter in different directions: at the level of the moss-lichen layer, at the level of the grass-shrub layer and at a height of 1.3 m; at different distances from the tree trunk; at different distances from the edge of the forest. Illumination in pine forests at the level of the moss-lichen layer is 2.3 times higher than in spruce forests. Under the canopy of spruce forests, it is 1–3%, and in the pine forests, 3–9% of the illumination in the open. Illumination from tree trunks to the edge increases in pine and spruce forests equally. The lowest illumination is observed at the level of the moss-lichen layer, then it increases to the grass-shrub layer, and then practically does not change. However, the difference between pine and spruce forests is consistently high 47%. The decrease in illumination in the tree stand as it moves away from the edge in blueberry pine forests is observed up to a distance of 10 m from the edge, and in blueberry spruce forests up to 6 m.

    Kampinos Forest
    Opis:
    Forests in Kampinos National Park contain some of the most valuable tree populations in Poland. Particularly interesting are stands of Scots pine (Pinus sylvestris L.) that are more than 130-years-old. Periodic observations of the health of tree crowns in these stands facilitates a wide range of research investigations. This article evaluates statistical relationships between allometric features of trees and the occurrence and severity of crown defoliation. Observations were made of 5 pine populations in 2017 and 2019, in which detailed data were collected for 250 trees. The percentage loss of the assimilation apparatus and level of stand damage were calculated. The results revealed a significant increase in defoliation between 2017 and 2019. The deterioration of crown condition was particularly evident on the most fertile sites. The degree of crown damage was not correlated with tree height or diameter. The greatest increase in defoliation between 2017 and 2019 was observed for the most severely damaged trees growing on fertile sites. This study contributes analyses aimed at correlating the allometric features of a stand with its health. Such information is valuable as it describes the status of the analysed stands, as well as providing information about how trees have responded to environmental conditions. In this study, crown defoliation coincided with a period of drought in Poland, which appears to have affected pine stands. For these reasons, the results are of both scientific and practical value.

    Opis:
    The aim of our study was to compare the growth rates of lodgepole pine (Pinus contorta Dougl.) with those of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L.) in plantations. The experimental plots were established in 1988, 1989 and 1994 in the southern part of the Leningrad region. In 2014, the condition of the plants on those plots was examined and their linear parameters were measured. The comparison of Scots pine with lodgepole pine of the same age growing in similar soil conditions has shown that Scots pine has only an insignificant advantage over lodgepole pine in the growth rate. In the mixes of Norway spruce and lodgepole pine, Norway spruce considerably suppresses the growth of lodgepole pine. Lodgepole pine has successfully adapted to the climatic conditions of the Leningrad region of Russia, which is easy to see from the well-preserved plantations and their annual bearing. No significant damage because of either diseases or insect pests has been revealed. It is for the first time that the volume yield of lodgepole pine was determined in 20- to 26-year-old experimental plantations in the Leningrad region of Russia.

    This research is aimed at determining the health condition and productivity of Scots pine (Pinus sylvestris L.) stands created during 1906–1908 on the initiative of Prof. V. D. Ogievsky. The scheme of silvicultural experiments included: determining the influence of different widths and directions of clear felling on the natural regeneration, testing of pine plantations of pure and mixed composition and the choice of methods for their creation. In terms of health condition, 103–105-year-old artificial pine stands are weakened and their health condition is slightly worse compared to the aged pines of natural origin. The productivity of age-old linden-pine plantations is higher than of pure pine plantations, and the stock of stem wood in plantations created by seed sowing and marketability is higher compared to the plantations created by planting seedlings.

    Opis:
    The weather conditions determine the dynamic forest fire risk. In Poland, the dynamic forest fire risk is calculated using a method elaborated at the Forest Research Institute. The forest fire risk degree (4-level scale) is calculated every day at 9:00 am and at 1:00 pm during the fire season (1.03 till 30.09) for 60 prognostic zones selected on the basis of stand and climatic conditions. 97% of all annual forest fires occur during the fire season. Surface fires are a significant part of the fires (90%) and occur in forest stands where pine is the dominant species. The purpose of the research was to prepare a new method of forecasting forest fire risk, which would enable a more precise method of evaluation of the risk of an outbreak of fire in relation to the existing and forecast meteorological conditions in forests. The results obtained during testing of this method indicate a high accuracy in forecasting fire risk and a satisfactory precision of formulae for calculating moisture content of pine litter. The assumptions of the new method included: – possibility of determining the actual risk of fire for the given area, being the average for all measurement points located on the terrain equally those in which the moisture content measurement of litter has not been performed, – possibility of forecasting the risk of forest fire for the afternoon in the morning hours of the given day, – possibility of forecasting fire risk for the following day, – forecasting moisture content of litter for the afternoon and of the given day and for the following day, – drawing up a method enabling limitation of operational costs of fire prevention system.

    Opis:
    The paper presents the results of an analysis of the influence of soil bulk density in a forest nursery plot on the growth and quality parameters of Scots pine and European beech seedlings. Particular density variants were obtained using a tractor device exerting controlled pressure on the soil, while field examinations were performed on an area of ‘Kłaj’ forest nursery in Niepołomice Forest District. Three series of plots were prepared for each species, applying a unit pressure of the values of 50, 100, 150, 200, 250 kPa, corresponding to the dry bulk density in the range of 1.03-1.19 g cm-3, and control plots without the pressure. Seeds of the examined species were sown on the prepared plots, and after 6 months of growth the seedlings were subjected to biometric analysis determining differentiation in root neck diameter, length of the above-ground part and root system, as well as dry mass of particular parts of the plant. The quality of the seedlings was also determined using the method of Schmidt-Vogt. The results obtained show that the change in dry bulk densitysoil significantly affected most of the growth parameters of theexamined seedlings. Especially high negative correlations were obtained for the length and dry mass of the root system. A significant influence of dry bulk density variant on all growth parameters of Scots pine seedlings, and on some parameters of European beech was demonstrated. An increase in soil bulk density clearly caused also a deterioration of European beech seedlings quality.

    Opis:
    This study examined the effect of fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark and mulching with fresh forest ectohumus on selected growth parameters for two - and three-year-old Scots pine trees and on the incidence of mites (Acari) in the soil. The experiment was carried out in 2009-2010 in the Białe Błota forest nursery (Bydgoszcz Forest District) on proper rusty soil. The entire area of the experiment was irrigated with a stationary sprinkler. Organic fertilisation with compost prepared from hygienised sludge with an addition of pine-tree bark resulted in a significant increase in the plant height and the diameter of the root neck in two-year-old pine trees. The effect of mulching on these parameters was not significant. The synergistic effect of the factors on the plant height and the diameter of the root neck was not significant. Organic fertilisation significantly increased the height of 3-year-old pine trees, whereas it did not have a significant effect on the root neck diameter. Mulching increased the plant height significantly, but no statistical effect on the diameter of the root neck was demonstrated. Although no significant interaction of either experimental factors in their effect on the plant height and the diameter in the root neck was observed, the parameters tended to increase in the experimental option, which included organic fertilisation and mulching. Mulching had a significant effect on the presence of soil mites, especially oribatid mites (Oribatida). Their density increased greatly after the procedure. This growth, as well as an increase in the ratio of Oribatida to Actinedida could be a sign of improvement of the biological balance of the soils under study and their biological activity.

    The paper shows differences in morphological and anatomical features of the Scots pine (Pinus sylvestris L.) growing on former agricultural and forest lands. It was found that at the same age and in the same climatic conditions Scots pines from former agricultural land had larger stem dimensions and needle sizes as compared with the trees growing on forest land. These results lead to an interesting conclusion connected with future afforestation and reforestiation in the Krynki Forest District.

    Forest bed layer developing in a tree stand plays a very important part in functioning of forest ecosystem and is of key importance in soil carbon accumulation. In two different study objects (Niedźwiady and Tuczno), 351 forest bed thickness measurements were taken in 117 pine stands of different age classes, separating them into those growing on forest lands (28 tree stands – 84 measurements) and those on post−agricultural ones (89 tree stands – 27 measurements). The above relationships were analysed, what showed a relation between the thickness of forest bed and the age of tree stand. Forest bed thickness increases together with tree stand age, both on forest and post−agricultural soils.

    Opis:
    The soil accumulates many chemical pollutants including heavy metals. In order to evaluate pollution of the environment the soil samples were taken on four forest stands in the Mogilski forest, in the Niepo³omicka primeval forest, in Skalki Twardowskiego Landscape Park and in the grove in Zawada. At these stations also collected necrotic bark of the common pine (Pinus sylvestris L.), which is a popular tree in Poland. The outer bark of common pine is extremely sensitive biomarkers of environmental pollution. The content of heavy metals in the forest soils at four positions, and the bark of pine forest growing on these soils. Chemical analyses of heavy metals were performed by determining the contents of general forms of lead, cadmium, copper, nickel and zinc using the AAS method. The range of metals content in soils amounted to properly: 0.47–2.32 ppm Cd; 9.98–73.7 ppm Pb; 72.5–224.9 ppm Zn; 6.39–12.17 ppm Ni and 7.69–10.85 ppm. The results indicate that the concentrations of heavy metals do not exceed the standards set out in the Regulation of the Minister of the Environment on soil quality standards and earth quality standards (Polish Journal of Laws DzU 2002 No. 165, item 1359 of 4 October 2002). The content of lead, copper and nickel in the studied soils were higher than in the bark of trees growing in this stations. The concentration of cadmium was varied at different positions. The highest content of Cd was observed both in the soil (2.32 ppm) and in the necrotic pine bark (1.55 ppm) in Skalki Twardowskiego Landscape Park, that is a part of Bielansko Tyniecki Landscape Park.
    Gleba kumuluje wiele zanieczyszczeń chemicznych w tym również metale ciężkie. Dla oceny zanieczyszczenia środowiska pobierano próbki glebowe na czterech stanowiskach leśnych – w Lesie Mogilskim, w Puszczy Niepołomickiej, w ok. 40-letnim zagajniku sosnowym w Parku Skalki Twardowskiego i w zagajniku w Zawadzie. Na tych stanowiskach pobierano również korę martwicową sosny zwyczajnej (Pinus sylvestris L.), która jest popularnym drzewem w Polsce. Kora martwicowa sosny zwyczajnej jest wyjątkowo czułym biowskaźnikiem zanieczyszczenia środowiska. Badano zawartość metali ciężkich w glebie na czterech stanowiskach leśnych i w korze sosen rosnących na tych glebach. Analizy chemiczne dotyczące metali ciężkich przeprowadzono, wyznaczając zawartość ogólnych form ołowiu, kadmu, miedzi, cynku i niklu metodą AAS. Zawartości metali ciężkich w badanych glebach wynosiły odpowiednio: 0,47–2,32 mg/kg Cd; 9,98–73,7 mg/kg Pb; 72,5–224,9 mg/kg Zn; 6,39–15,79 mg/kg Ni i 7,69–10,85 mg/kg. Wyniki badań wskazują, że stężenia metali ciężkich nie przekraczają norm określonych w Rozporządzeniu Ministra Środowiska w sprawie standardów jakości gleby oraz standardów jakości ziemi (DzU 2002, nr 165 poz. 1359 z dn. 4.10.2002). Zawartość ołowiu, miedzi i niklu w glebie na wszystkich stanowiskach była wyższa niż w korze rosnących na tym obszarze drzew. Stężenie kadmu było zróżnicowane na poszczególnych stanowiskach. Najwyższą zawartość Cd odnotowano zarówno w glebie (2,32 mg/kg), jak i w korze martwicowej sosny (1,55 mg/kg) na stanowisku usytuowanym w Parku Skalki Twardowskiego należącym do Bielańsko-Tynieckiego Parku Krajobrazowego w Krakowie.

    Opis:
    The research was aimed at analysing the peculiarities of non-structural carbohydrate metabolism in the needles of Pinus pallasiana D. Don in anti-erosion plantations on the slope and in the thalweg of the Viyskovyi ravine under different forest growth conditions. The ravine is located in the Dnipropetrovsk region and belongs to the southern geographical variant of ravine forests. The studied plants grew at three experimental sites of man-made plantation: in the thalweg (forest growth conditions – mesophilic, fresh, CL2), in the middle part of the slope of the southern exposure (mesoxerophilic, somewhat dry, or semi-arid, CL1) and on the upper part of this slope (xerophilic, arid, CL0–1). Changes in glucose, fructose, reducing sugars, sucrose and starch during the period from May to October were studied. The concentration of osmotically active substances (glucose, sucrose) increases in the months with the most unfavourable hydrothermal parameters, especially in plants of mesoxerophilic and xerophilic forest growth conditions. The dynamics of fructose content revealed two maxima (July and October), when the concentration of glucose tends to increase steadily, with the highest values found in October. During the study period, the level of fructose in the needles under the arid conditions of the upper and middle parts of the slope was much lower than under the fresh conditions of the thalweg. The dynamics curve of the starch content tends to decrease from the maximum values in May to the first minimum in August. It is followed by some increase in the concentration of this polysaccharide that does not reach the previous values. The second minimum is registered in October. Such changes in the level of starch in the needles of plants are observed under all forest growth conditions. The decrease in polysaccharide content is consistent with the increase in glucose and sucrose, especially in August. A more significant increase in the concentration of soluble osmoprotective sugars (glucose, sucrose) in P. pallasiana needles under unfavourable hydrothermal conditions compared to normal moisture conditions indicates the ability of plants to adapt to mesoxerophilic and xerophilic conditions.

    Opis:
    Gleba kumuluje wiele zanieczyszczeń chemicznych, w tym również metale ciężkie. W celu oceny zanieczyszczenia środowiska pobierano próbki glebowe na czterech stanowiskach leśnych - w Lesie Mogilskim, w Puszczy Niepołomickiej, w ok. 40-letnim zagajniku sosnowym w Parku Skałki Twardowskiego i w zagajniku w Zawadzie. Na tych stanowiskach pobierano również korę martwicową sosny zwyczajnej (Pinus sylvestris L.), która jest popularnym drzewem w Polsce. Kora martwicowa sosny zwyczajnej jest wyjątkowo czułym biowskaźnikiem zanieczyszczenia środowiska. Badano zawartość metali ciężkich w glebie na czterech stanowiskach leśnych i w korze sosen rosnących na tych glebach. Analizy chemiczne dotyczące metali ciężkich przeprowadzono, wyznaczając zawartość ogólnych form ołowiu, kadmu, miedzi, cynku i niklu metodą AAS. Zawartości metali ciężkich w badanych glebach wynosiły odpowiednio: 0,47-2,32 ppm s.m. Cd; 9,98-73,7 ppm s.m. Pb; 72,5-224,9 ppm s.m. Zn; 6,39-15,79 ppm s.m. Ni i 7,69-10,85 ppm s.m. Cu. Wyniki badań wskazują, że stężenia metali ciężkich nie przekraczają norm określonych w Rozporządzeniu Ministra Środowiska w sprawie standardów jakości gleby oraz standardów jakości ziemi (DzU 2002, Nr 165, poz. 1359 z dn. 4.10.2002). Zawartość ołowiu, miedzi i niklu w glebie na wszystkich stanowiskach była wyższa niż w korze rosnących na tym obszarze drzew. Stężenie kadmu było zróżnicowane na poszczególnych stanowiskach. Najwyższą zawartość Cd odnotowano zarówno w glebie (2,32 ppm s.m.), jak i w korze martwicowej sosny (1,55 ppm s.m.) na stanowisku usytuowanym w Parku Skałki Twardowskiego należącym do Bielańsko-Tynieckiego Parku Krajobrazowego w Krakowie.
    The soil accumulates many chemical pollutants including heavy metals. In order to evaluate pollution of the environment the soil samples were taken on four forest stands in the Mogilski forest, in the Niepolomicka primeval forest, in Skalki Twardowskiego Landscape Park and in the grove in Zawada. At these stations also collected necrotic bark of the common pine (Pinus sylvestris L.), which is a popular tree in Poland. The outer bark of common pine is extremely sensitive biomarkers of environmental pollution. The content of heavy metals in the forest soils at four positions, and the bark of pine forest growing on these soils. Chemical analyses of heavy metals were performed by determining the contents of general forms of lead, cadmium, copper, nickel and zinc using the AAS method. The range of metals content in soils amounted to properly: 0.47-2.32 ppm d.m. Cd; 9.98-73.7 ppm d.m. Pb; 72.5-224.9 ppm d.m. Zn; 6.39-12.17 ppm d.m. Ni and 7.69-10.85 ppm d.m. Cu. The results indicate that the concentrations of heavy metals do not exceed the standards set out in the Regulation of the Minister of the Environment on soil quality standards and earth quality standards (Polish Journal of Laws DzU 2002 No. 165, item 1359 of 4 October 2002). The content of lead, copper and nickel in the studied soils were higher than in the bark of trees growing in this stations. The concentration of cadmium was varied at different positions. The highest content of Cd was observed both in the soil (2.32 ppm d.m.) and in the necrotic pine bark (1.55 ppm d.m.) in Skalki Twardowskiego Landscape Park, that is a part of Bielansko-Tyniecki Landscape Park.

    Opis:
    This paper presents processing and analysis techniques to apply LiDAR data to estimate tree diameter at breast height (DBH) - a critical variable applied in a large number of forest management tasks. Our analysis focuses on the estimation of DBH using only LiDAR-derived tree height and tree crown dimensions, i.e., variables accessible from aerial observations. The modeling process was performed using 161 white and red pine trees from four 3850 m2 plots in the Foret de l'Aigle located in southwestern Quebec. Segments of the LiDAR data extracted for DBH estimation were obtained using the Individual Tree Crown (ITC) delineation method. Regression models were investigated using height as well as crown dimensions, which increased the precision of the model. This study demonstrates that DBH can be modeled to acceptable accuracy using altimetry data and automated data processing procedures and then be used in high-precision timber volume assessment.

    Opis:
    Ectomycorrhizas of Scots pine (Pinus sylvestris L.) and beech (Fagus sylvatica L.) were sampled in a mature forest ecosystem exposed for more than 40 years to moderate levels of gaseous and dust pollutants. Soil of the forest site was characterised by low pH and accumulation of heavy metals (Pb, Mn, Zn, Cu, Cd, Fe). Mycorrhizal vitality and enzyme activity of the root-surface and soil acid phosphatase (AcPase) were studied at 17 measurement points (0–5 cm soil depth) in relation to the content of inorganic phosphate (Pi) and aluminium ions (Al3+) in the soil. Anatomy of Scots pine and beech mycorrhizas taken from different measurement points was observed. The concentration of essential nutrients (C, N, P, Ca, Mg) and the ratios Ca/Al, Mg/Al and N/P were analysed in fine roots. High concentrations of Al3+ in the soil (40–118 meq kg-1) and low levels of Pi (12–44 mg P2O5 kg-1) were accompanied by high activity of the root-surface AcPase of pine and beech mycorrhizas (25–67 and 33–86 μmol pNP g-1 fresh weight h-1, respectively) and soil AcPase (6.8–22.4 μmol pNP g-1 dry weight h-1). The results indicate that fine tree roots are undoubtedly under stress as evidenced by a disturbance in P uptake and accumulation. However, the high vitality of mycorrhizas and the high Ca/Al ratio in fine roots suggest that the defence mechanisms of mycorrhizas and the rhizosphere are still able to ameliorate the influence of anthropogenic pollution.
    Badania ektomikoryz sosny (Pinus sylvestris L.) i buka( Fagus sylvatica L.) prowadzono na Pogórzu Karpackim w dorosłym drzewostanie, który przez ponad 40 lat znajdował się pod wpływem gazowych i pyłowych zanieczyszczeń powietrza o średnich stężeniach. Gleby badanego ekosystemu leśnego cechowało niskie pH oraz znaczna akumulacja metali ciężkich (Pb, Mn, Zn, Cu, Cd, Fe). Badano zależność między stężeniem nieorganicznego fosforanu w glebie, a aktywnością enzymatyczną kwaśnej fosfatazy mikoryz i gleby. Analizowano także stężenia pierwiastków odżywczych (C, N, P, Ca, Mg) oraz jonów glinu (Al3+) w korzeniach drobnych. Mikoryzy sosny i buka były analizowane pod względem budowy anatomicznej oraz żywotności. Stwierdzono stosunkowo wysokie stężenie jonów Al3+ w glebie (40–118 meq kg-1) i niski poziom nieorganicznego fosforanu (Pi) (12–44 mg P2O5 kg-1). Jednocześnie zarejestrowano wysoką aktywność powierzchniowej kwaśnej fosfatazy mikoryz sosny i buka(odpowiednio, 25–67 i 33–86 μmoli pNP g-1 świeżej masy h-1) oraz kwaśnej fosfatazy gleby (6,8–22,4 μmoli pNP g-1 suchej masy h-1). Stężeniafosforu w korzeniach drobnych (poniżej stężeń uważanych za optymalne) oraz wysoki stosunek N/P pokazują, że pobieranie i akumulację fosforu przez systemy korzeni drobnych sosny i bukajest niedostateczne, mimo wysokiej aktywności kwaśnej fosfatazy. Budowa anatomiczna mikoryz, stosunkowo duży udział żywych mikoryz w systemie korzeni drobnych oraz wysoki stosunek Ca/Al w korzeniach sosny i buka(odpowiednio, 1,79 i 2,38) sugerują, że mechanizmy obronne mikoryz i mikroorganizmów ryzosfery mają zdolność łagodzenia wpływu zanieczyszczeń antropogenicznych.

    Opis:
    Mycorrhizal syntheses of pine seedlings were conducted with Suillus luteus (L.) S.F. Gray, a strain No 14 characterised by high tolerance to Al3+ ions and a strain No 62, sensitive to aluminium. The experiment was performed as a semi-sterile culture in a peat-perlite medium with Al3+ ion concentration of 11 mM. Abundant coralloid and cluster mycorrhizas of S. luteus were formed on roots of the inoculated plants at the beginning of the experiment. Aluminium treatment limited mycorrhizal morphotypes to single and dichotomous and significantly reduced the total number of mycorrhizal tips but had no effect on extramatrical mycelium development in the potting substrate. Al treatment did not affect growth of the above-ground part of the tested plants but significantly reduced root growth of mycorrhizal seedlings. The effect of Al on the internal nutrient status was variable and not very much pronounced. A considerable amount of Al was absorbed by the roots and translocated to the shoots. Mycorrhiza formation with both strains of S. luteus did not prevent Al3+ translocation to the upper parts of the tested seedlings. The results suggest that low pH and high Al availability may harmfully influence mycorrhizal symbiosis of Scots pine (Pinus sylvestris L.) by anega tive effect on fine-root production and fewer short root tips available for colonisation rather than through a direct negative effect of Al3+ ion concentrations on extramatrical mycelium in the soil.
    Syntezę mikoryzową siewek sosny (Pinus sylvestris) z odpornym naglin szczepem Suillus luteus nr 14 i wrażliwym na glin szczepem nr 62 przeprowadzono w warunkach półsterylnych w szklarni. Po nawiązaniu mikoryzy siewki przez 6 miesięcy traktowano roztworem glinu o stężeniu 11 mM przy pH = 3,8. W warunkach kontrolnych (bez glinu) oba szczepy S. luteus tworzyły obfite mikoryzy pojedyncze oraz dichotomicznie i koralowato rozgałęzione. Traktowanie glinem zredukowało morfotypy mikoryzowe do pojedynczych i dichotomicznych oraz znacząco zmniejszyło całkowitą liczbę wierzchołków mikoryzowych na korzeniach siewek, ale nie ograniczyło rozwoju grzybni ekstramatrykalnej. Wwarunkach kontrolnych (bez glinu) rozwój grzybni ekstramatrykalnej, mierzony zawartością ergosterolu w podłożu był podobny w przypadku obu testowanych szczepów. Traktowanie glinem spowodowało pewien wzrost rozwoju grzybni ekstramatrykalnej szczepu tolerancyjnego i nieznaczne zahamowanie wzrostu szczepu wrażliwego. Glin ograniczył znacząco wzrost korzeni, natomiast nie stwierdzono negatywnego wpływu glinu na wzrost części nadziemnych siewek. Siewki traktowane glinem absorbowały w korzeniach znaczne ilości tego metalu, który był także przemieszczany do pędów. Stwierdzono niewielki wpływ glinu na zawartość pierwiastków mineralnych w siewkach. Badania wykazały, że przy zastosowanym wysokim stężeniu glinu szczep Nr 14 wyselekcjonowany w warunkach in vitro jako odporny na glin, nie zahamował przemieszczania jonów Al3+ do części nadziemnych siewek sosny. Wyniki sugerują, że szkodliwe działanie jonów glinu na symbiozę mikoryzową w warunkach niskiego pH polegara czej naogra niczeniu liczby wierzchołków korzeni drobnych, które potencjalnie mogą tworzyć mikoryzy, niż nabezpośrednim wpływie na grzybnię mikoryzową.

    Opis:
    A lichenological inventory was conducted in the pine stands in the south-eastern region of Żerków-Czeszewo Landscape Park. The aim of this study was to recognize the lichen species diversity on the bark of Pinus sylvestris by considering tree age and forest habitat type. In total, 26 species of lichenized fungi were found on the bark of P. sylvestris. The biota comprises common and widespread species in Poland. Tree age positively and significantly influenced the species richness on the bark of P. sylvestris. The suitability of the pine tree age for lichens evident as alpha diversity seemed to be independent from the habitat of the trees. The age of phorophytes strongly affected the presence of Hypocenomyce scalaris. Mixed fresh coniferous forests were characterized by higher beta- and gamma diversity compared to fresh coniferous forests. There was no correlation between the number of species per tree (alpha diversity) and diversification of species composition in relation to the distance between pines. The findings indicate that maintenance of a variety of phorophytes and age-diversified tree stands can prevent impoverishment of the lichen biota in the south-eastern part of Żerków-Czeszewo Landscape Park.

    Opis:
    Celem pracy była ocena zaopatrzenia w składniki pokarmowe sosny zwyczajnej (Pinus sylvestris L.) w I klasie wieku (do 20 lat) rosnącej na wierzchowinie zwałowiska zewnętrznego Kopalni Węgla Brunatnego "Bełchatów" i w lasach gospodarczych w sąsiedztwie zwałowiska. Badania prowadzono na 60 powierzchniach doświadczalnych (10 x 10 m) w chronosekwencji 5-7, 9-11 i 12-14 lat, po 10 powtórzeń dla każdej grupy wieku na zwałowisku i w drzewostanach gospodarczych. Stwierdzono, że w warunkach bełchatowskiego zwałowiska najbardziej deficytowym pierwiastkiem był azot, którego średnia zawartość w igłach wynosiła od 0,8 do 0,9%. Na podstawie wyników pomiaru wysokości sosny i długości igieł ustalono, że dobry wzrost egzemplarzy tego gatunku miał miejsce przy zawartości azotu w jej aparacie asymilacyjnym wynoszącym co najmniej 1,0% N. Zawartości pozostałych ważnych dla drzew biogenów (Ca, Mg, K. P, S) w igłach sosny uznano za wystarczające, przy czym zawartość fosforu w igłach sosny na zwałowisku była wyraźnie niższa w porównaniu do aparatu asymilacyjnego sosny z lasów przyległych do zwałowiska. Proporcje poszczególnych makroelementów zawartych w igłach sosny były korzystne, a średnie zawartości układały się w charakterystyczny dla tego gatunku szereg ilościowy: N > K > Ca > P > Mg. Uzyskane wyniki pokazują, że za wyjątkiem azotu inicjalne gleby zwałowiska zapewniają wprowadzonej w ramach rekultywacji sośnie zwyczajnej większość składników pokarmowych.
    The aim of the work was to assess the Scots pine (Pinus sylvestris L.) nutrient supply in the first age group (of up to 20 years) growing on the top of the external slope in the Bełchatów lignite mine and in managed forests in the vicinity of the dump. The research was conducted on 60 experimental plots (10x10 m) in a chronosequence of 5-7, 9-11 and 12-14 years, with 10 repetitions for each age group on the slope and in managed tree stands. It was found that nitrogen was the most deficient element in the Bełchatów dump. Its average content ranged from 0.8 to 0.9%. Based on the results of pine high and needle length measurements it was established that satisfactory growth of the trees from this species took place when nitrogen content in its assimilation apparatus was at least 1.0% N. The content of other biogenes important for trees (Ca, Mg, K, P, S) was considered satisfactory in pine needles, however the phosphate content in the slope was visibly lower than in the assimilated material of pines from forests in the vicinity of the dump. The proportions of individual macroelements in pine needles were satisfactory and the mean content appeared in quantitative series characteristic for the species: N > K > Ca > P > Mg. The obtained results show that with the exception of nitrogen, the initial soils of the dump provide the majority of nutrients for the Scots pine introduced as part of the reclaim process.

    Opis:
    Two fundamental demographic processes (tree recruitment and mortality) are analyzed for forest stands growing on permanent study plots located in strictly protected Scots pine−dominated, old−growth stands of Kampinos National Park (central Poland). The major implications of the observed demographic trends for the general shape of tree size distributions are determined, as well. During the past ca 30 years, in the stands sampled, there was a pronounced lack of balance between mortality and recruitment processes. Mortality rate was eight times higher than recruitment rate. Eventually, there was a net significant decline in population density, observed for all major tree species, including Scots pine, pedunculate oak, silver and downy birch, and black alder. As mortality processes affected mainly smaller trees, there was also a significant deterioration of the general demographic status of most important tree species. This effect was shown by the change of the overall shape of diameter distributions over the study period: from reverse J−shaped to flat curves running nearly parallel to X−axis. The values of recruitment rates were markedly lower, and the values of mortality rates – significantly higher, than analogous values characterizing comparable forests (e.g., those obtained for the natural stands of Białowieża National Park). Low recruitment rates, as obtained for Kampinos stands, suggest that presently, in the local, Scots pine−dominated, old−growth stands, the general conditions for forest regeneration and for maintaining a long−term demographic stability are unfavorable. Most probably, the regeneration of this type of forest has an episodic, ‘wave−like’ character and corresponds to the ‘catastrophic’ model, according to which the successful regeneration of current dominants (especially Scots pine, silver and downy birch, black alder) must be preceded by a stand−initiating (stand−replacing) disturbance, leading to total or partial, but heavy, destruction of the currently existing stand. At the moment, it would be difficult to predict, however, if and when such a disturbance will affect the stands under investigation. Thus, we predict that in the nearest future at least, the state of overall demographic unbalance will continue or even increase.

    Opis:
    Celem pracy była ocena potencjalnych możliwości produkcji biomasy drzewostanów sosnowych (Pinus sylvestris L.) I klasy wieku (do 20 lat) wzrastających na wierzchowinie zwałowiska zewnętrznego kopalni węgla brunatnego "Bełchatów" oraz możliwości pozyskania z nich w przyszłości energii odnawialnej. Badania prowadzono w 12 - 19-letnich drzewostanach na 8 powierzchniach doświadczalnych (10 x 10 m) w dwóch wariantach troficznych siedlisk (1- na czwartorzędowych piaskach gliniastych i glinach oraz 2- trzeciorzędowych utworach kwaśnych po neutralizacji), po 4 powtórzenia dla wariantu. Jedną powierzchnię kontrolną założono w drzewostanie gospodarczym. Stwierdzono, że siedliska na wierzchowinie zwałowiska wykazują zróżnicowany potencjał dla produkcji biomasy, która może posłużyć jako biopaliwo oraz może brać udział w naturalnym procesie sekwestracji węgla. Biomasa drzewostanów wahała się w przedziale od 8 to 40 Mgxha/-1, a średnio 25 Mgxha/-1 suchej masy. Potencjalne możliwości produkcji energii odnawialnej z biomasy oszacowano na 80 do 400 kJ X 10/6 ha/-1, a średnio 240 kJ x 10/6 ha/-1, co stanowiło średnio około 40% w stosunku do porównywanego siedliska naturalnego. Ilość energii potencjalnie zakumulowanej w drzewostanie na całej powierzchni wierzchowiny (ok. 300 ha) może wynosić już w I klasie wieku drzewostanów od około 24 000 do 120 000 kJ x 10/6 ha/-1, a średnio 72 000 kJ x 10/6 ha/-1. Przy czym uwzględniając dynamiczny przyrost biomasy w wieku około 20 lat może to wynosić ponad 130 000 kJ X l0/6ha/-1. Uzyskane wyniki wskazują na jedną z możliwych form wykorzystania i zagospodarowania rekultywowanych siedlisk pogórniczych dla plantacji drzew i produkcji energii odnawialnej.
    The aim of the work was to quantify the biomass, and potential for renewable energy production, of a stand of Scots Pine (Pinus sylvestris L.), in the first age group (up to 20 years), that grow on the external slope of the "Bełchatów" lignite mine. The results were compared to managed forests in the vicinity of the slope. The research was conducted on 8 experimental plots (10 x 10 meters) in two trophy variants (quaternary loamy sands and tertiary pyrytic strata after neutralization) using 12-19 year old tree stands, with 4 replications for each variant. One control plot was arranged in managed tree stands adjacent to the mine. It was found that post-mining sites, compared natural site, have an average 30% potential for biomass production and carbon sequestration. The range of tree stands' biomass, on the lignite mine slope, was 8 to 40 Mg ha/-1, and average 25 Mg ha/-1 dry biomass. Potential production of renewable energy was estimated to be 80 to 400 kJha/-1 x 10/6, and average 240 kJ x 10/6ha/-1. Total energy potential on the external slope plateau (approximately 300 ha) was 24 000 to 12 000 and average 130 000 kJ x 10/6 ha/-1. The results show the potential to manage post-mining sites, as tree plantations for renewable energy production.

    Opis:
    Provenance trials with forest trees provide valuable information about growth and adaptability of populations often transferred over large geographical and climatic distances. In this study we evaluated growth and survival of 19 Scots pine (Pinus sylvestris L.) populations representing most of the natural range of the species in Europe, growing in a 30-year-old provenance trial in the northeastern Poland. We used cluster analysis to investigate differentiation among those populations in growth and survival. We also used published data on needle morphology and allozyme and DNA marker variation for those same populations to compare groupings of populations based on growth and needle traits and markers. We found significant variation among tested populations in all investigated traits – the largest variation was found for stand volume which integrates information on growth and survival. Variation in growth traits was related to the latitude of population origin with populations from the latitudinal band between 49° N and 54° N showing the best performance. Populations originating from both north and south off of that region showed lower productivity, which for southern provenances resulted from their particularly low survival, reflecting the lack of adaptation to the environment of the research site. Grouping of populations based on growth traits revealed three clusters corresponding to the three latitudinal regions – northern, central and southern. Needle morphological traits were not appropriate as markers of productivity. Clustering of populations based on needle morphology, and especially based on biochemical and molecular markers, did not correspond to the grouping based on growth traits.

    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:
    DNA amplification was investigated in order to determine fungal species present in the Koronevka forest nursery (eastern part of Belarus). For this purpose, needles and roots of Scots pine (Pinus sylvestris L.) seedlings as well as soil collected around roots were examined for ITS1– 5.8S RNA-ITS2 region sequences and compared with GenBank data. DNA analysis of seedlings microflora and soil samples allowed identification of twelve different species of fungi. Among these Cladosporium herbarum Link, Davidiella tassiana Crous and U. Braun, Alternaria alternata Nees and Cryptococcus pinus Vuill. were often found in symptomatic needles. Pathogenic fungal species were detected in 57% of shrunken needles. Examination of DNA extracted from seedling roots revealed occurrence of Wilcoxina mikolae Chin S. Yang and Korf, C. herbarum, and A. alternata. In soil samples there were identified fungi of the same species, with predominance of mycorrhizal fungus W. mikolae (in 100% of samples) and C. pinus (in 20% of samples). The results demonstrated usefulness of molecular markers for the detection and identification of fungi.

    Opis:
    Celem podjętych badań był wstępny monitoring stężeń wybranych metali ciężkich (Cd, Co, Cr, Ni, Pb, Zn) w igłach sosny zwyczajnej (Pinus sylvestris L.) w zależności od miejsca poboru próbek. Do badań wytypowano trzy obszary badawcze (Świeradów Zdrój, Świnoujście, Byszyno), z których pobrano łącznie 14 próbek zbiorczych. Stężenia metali ciężkich oznaczone w próbkach igieł sosny zwyczajnej pochodzących z jednego obszaru badawczego są zbliżone. Świadczyć to może o zdolnościach bioindykacyjnych sosny zwyczajnej. Stężenia poszczególnych metali ciężkich pochodzące z trzech różnych obszarów badawczych wykazują duże różnice w ich stężeniu. Analizy statystyczne wykazały statystyczne istotne różnice (test Tukeya p≤0,05) stężeń wybranych metali ciężkich w próbkach igieł sosny zwyczajnej jedynie z obszaru Świeradowa Zdrój.
    The aim of the research was preliminary monitoring of selected heavy metals (Cd, Co, Cr, Ni, Pb Zn) concentrations in pine needles (Pinus sylvestris L.). Three research areas were selected for the study (Świeradów Zdrój, Świnoujście, Byszyno), from which a total of 14 aggregate samples were collected. Heavy metals concentrations in Scots pine needles samples from one research area were similar. This may indicate the bioindication abilities of Scots pine. Concentrations of individual heavy metals, from three different research areas, showed quite large differences. Statistical significant differences (Tukey›s test p≤0.05) of concentrations of selected heavy metals in samples of pine needles were noted only on the Świeradów Zdrój area.

    Opis:
    The paper discusses conditions and problems concerning natural regeneration of pine in the „Puszcza Białowieska” Promotional Forest Complex. The studies on pine regeneration established from self−seeding were carried out on permanent experimental plots occupied by fresh and fresh mixed coniferous forests site types. A space filling index used in the experiment was to define space occupied by pine regeneration the so−called „height sum”. A significance test of differences in mean values between the abundance and height sum (t−Student's test) was used for each experimental variant within the forests site types. Natural regeneration in the Białowieża Forest occurs infrequently. It can be found mainly in loose pine stands growing in fresh coniferous forest site types. Pine naturally regenerates most successfully in fresh and fresh mixed coniferous forest site types, on fenced clear−cuts with a few reserved trees, with soil prepared in furrows and well−performed tending treatments, as well as in pine stands with stocking 0.4 providing that the same conditions are maintained. The primary condition for successful natural regeneration of pine in the Białowieża Forest is its protection against animals in the form of fencing.

    Opis:
    During the last years an alarming dieback has occurred in 20 to 40 years old first-rotation pine stands (Pinus sylvestris L.) on mine sites, caused by the white rot fungus Heterobasidion annosum (Fr.) Bref. First thinning opens the infection path so that up to now 30 to 89 % of afforestations in different mining areas are affected. Infestation risk increases with rising pH of the top soil (0-30 cm). The mean pH(H2O) of the infestation foci is 6.2, whereas it is below 5.0 in uninfected stands. Common practise of lime amelioration speeds up the infection. Furthermore, soil water availability (PAWC) has a significant impact on the course of disease. The plant available water (0-100 cm soil depth) of dieback gaps is about 80 mm. In contrast, the water storage capacity of unin-fected reference plots falls below 50 mm.
    W ostatnich latach wystąpiło niepokojące zjawisko zamierania 20-40 letnich sosen (Pinus sylvestris L.) pierwszej rotacji na terenach pokopalnianych, spowodowane przez korzeniowca wieloletniego (Heterobasidion annosum (Fr.) Bref.). Pierwsze przerzedzenie otwiera drogę zakażenia tak, że do tej pory objęło ono od 30 do 89% zadrzewień na różnych obszarach pogórniczych. Odnotowano wzrost ryzyka infekcji wraz ze wzrostem odczynu powierzchniowego poziomu gleb (0-30 cm). Średnia pH(H2O) z ognisk zakażenia to 6,2, podczas gdy na powierzchniach niezakażonych wyniosła poniżej 5,0. Powszechną praktyką zahamowania tempa zakażenia jest wapnowanie gleb. Ponadto, na przebieg choroby znaczący wpływ wywiera dostępność wody w glebie (PAWC). Dostępna woda dla roślin (0-100 cm gł.) na obszarach zamierania to ok. 80 mm. W przeciwieństwie, na obszarach nie zainfekowanych zdolność zatrzymywania wody spada poniżej 50 mm.

    Opis:
    To evaluate the geographic variability of Pinus sylvestris populations seven morphological traits of needles of pines from IUFRO 1982 provenance trial have been analyzed. The studied populations originated from northern (>55°N in Russia, Sweden and Latvia), central (55-47°N in Poland, Germany, Belgium, France, Slovakia) andsouthern (<47°N in Hungary, Bosnia, Montenegro andTurkey) European ranges of Scots pine. The analyzedprovenance trial experimental areas were locatedin Kórnik (western Poland) andin Supraśl (north-eastern Poland). The greatest variation was found in needle length and number of stomata rows on the flat and convex side of a needle, whereas number of stomata per 2mmof needle length on flat and convex side of a needle was stable, with minor interpopulational variation. Biometrical analyses revealed a significant population × location interaction anda geographical pattern in interpopulational differentiation in both experimental sites, with the northern andsouthern European Scots pine groups of provenancesdiffering significantly from the group of central origin. The results obtainedare compatible with previous results of studies on provenance variability of the Scots pine from IUFRO 1982. In the light of available data, the influence of the Balkan glacial refugia of Pinus sylvestris on a present genetic diversity of this species in Europe and the reconstruction of Scots pine migration routes after the last glacial period are discussed.

    Opis:
    The problem of determining the dependence of the chainsaw on the density of wood, substantiation of effective options for the number of chainsaws in the assortment and whiplash method of logging is quite relevant. In the Far East of Russia, in particular, in the Amur region, the forest growth conditions are different from the western ones, and therefore, the properties of the wood differ from the generally accepted ones. The article describes forest growth conditions that influence the properties of the wood in areas of the Amur region. Using the method of density determination, the density of larch, pine and birch were studied for first time in the areas of the region. The dependence of the density on humidity, age, species, season of the year and the area of growth was found out. The results of the research showed that under humidity of 70%, the density of larch was 1088.99 kg/m3, it was 919.8 kg/m3 for pine and it was for birch 915.9 kg/m3.

    The aim of the study was to determine whether there is a correlation between breast height diameter, tree height and stem total volume of Scots pines, on the one hand, and volume and proportion of juvenile wood, on the other. The investigations comprised pure pine stands of the IInd, IIIrd, IVth and Vth age classes developed in conditions of fresh mixed coniferous forest. A distinct curvilinear correlation was found between volume and proportion of juvenile wood in tree stems and breast height diameter, height and stem total volume. Because of high values of determination coefficients (R2), which characterised the above-mentioned correlations, it seems appropriate to use these regularities to assess the quality of the timber raw material regarding the proportions of its volume and juvenile wood in stems of Scots pine trees.

    Opis:
    Field research was conducted in selected pine−spruce stands of the Oleśnica Śląska Forest District (SW Poland), where in 2004 intensive mortality of trees infested by I. typographus and I. duplicatus was observed. The results show that most I. typographus beetles hibernated under the bark of sample trees (71.2%). Most I. duplicatus beetles hibernated in forest litter and soil (90.5%). In the litter and soil samples, the largest number of hibernating beetles (of both species) were observed in the close neighborhood of tree stems, within the radius of up to l m (96.2% and 94.0% respectively). The estimated number of beetles hibernating in the forest litter and soil under the canopy of a single sample tree was 383 and 61, respectively. In bark samples I. typographus hibernated only as adult (imago).

    Opis:
    Ectomycorrhizal communities associated with Pinus sylvestris growing on dry coniferous forest habitat after the fire were studied. In order to investigate the fire effect on ectomycorrhizal fungi and changes of soil parameters in the upper (0−15 cm) soil layer three study plots were established: 1 – the control, 2 – fire zone left for artificial renewal (with the economic method of renewal) and 3 – fire zone left for natural renewal. The analysis of mycorrhizae revealed presence of eight mycorrhizal fungi on Scots pine roots and the value of Shannon−Wiener species diversity index H’ equaled to 1.76. The most abundant were mycorrhizae formed by Tomentella feruginea (31.7%) and Hebeloma crustuliniforme (23.3%). The fraction of Paxillus involutus and Rhizopogon sp. mycorrhizae was 16.7% and 13.0%, respectively. The lowest was the number of Thelephora terrestris mycorrhizae (only 1.7%). At the site 2, number of mycorrhizal fungi diminished to five and Shannon−Wiener species diversity index was also lower (1.37). The predominant were mycorrhizae of Cenococcum geophilum (26.7%) and P. involutus (21.7%), whilst the lowest were mycorrhizae of Suillus luteus (1.7%). Although at the third site the number of ectomycorrhizal fungi was the same as on the site 2, the dominance of Thelephora terrestris (66.7%) caused that Shannon−Wiener’s species diversity index was the lowest (1.05). Mycorrhizae of Paxillus involutus and Wilcoxina mikolae were characterised by similar abundance (13.3% and 11.7%, respectively). The lowest number of mycorrhizae was observed for Tomentella sp. (3.3%). Analysis of soil parameters showed an increase of pH on burnt sites in comparison to the control. The soil of burnt sites were also characterised by lower value of C and C/N ratio than the soil on the control treatment. The result showed that ubiquitous mycorrhizal fungi, such as T. terrestis, are able to persist on roots in changed soil environment with low content of nutritions.

    Opis:
    The paper discusses conditions and problems concerning natural regeneration of pine in the „Puszcza Białowieska” Promotional Forest Complex. The studies on pine regeneration established from self−seeding were carried out on permanent experimental plots occupied by fresh and fresh mixed coniferous forests site types. A space filling index used in the experiment was to define space occupied by pine regeneration the so−called „height sum”. A significance test of differences in mean values between the abundance and height sum (t−Student's test) was used for each experimental variant within the forests site types. Natural regeneration in the Białowieża Forest occurs infrequently. It can be found mainly in loose pine stands growing in fresh coniferous forest site types. Pine naturally regenerates most successfully in fresh and fresh mixed coniferous forest site types, on fenced clear−cuts with a few reserved trees, with soil prepared in furrows and well−performed tending treatments, as well as in pine stands with stocking 0.4 providing that the same conditions are maintained. The primary condition for successful natural regeneration of pine in the Białowieża Forest is its protection against animals in the form of fencing.

    Opis:
    Permanently balanced forest economy demands today a resignation from a constant model of the forest stand, which preferred the productive function of the forest, mostly without any consideration to its natural values formed by Mother Nature. Implanting on Polish grounds principles of multifunctional forest districts acknowledged as a breeding object of the whole forest ecosystem, giving in that way the forest economy a proecological dimension. Its a result from a general progress of civilization and achievements in forest science; reaching towards the needs and expectations from the society gaining a general acceptation from different environments. One of the fundamental elements implementing the ecosystem is to rebuild deformed and artificially barred forest phytocenosis. This refers especially to pure pine stands on habitats, in which trophoism potential explains breeding habitats species variety. A good help for the forester in this area can be a natural succesion of good, noble broad−leaved species like for example the oak. Succesion of this species takes on a special meaning in poor habitats, in which it without any special imposes enriches the biocenose with the whole positive outcome accompanying this process; it can also be a valuable clue to the potential fertility in the habitat and the complexity in the forest vegetation community. An important task is to lead the way for the oaks development from succesion to its fullest use as a natural presence in creating the future forest generation. The article below is devoted to this question describing the natural up growth of the oak in pine stands on the coniferous forest habitats in Forest District Różanna and the methods and results in which they are used for breeding.

    Pine stands growing in the littoral zone of Bełdany Lake were established by natural regeneration. On the sites under study pine forms multi−generation stands and regenerates continuously showing two culmination periods in the years 1770−1800 and 1930−1980. Pine population at the age of 200−230 years retains good quality and high vitality. Similarly, younger generation pines that grow under the shelter of the canopy even for 100 years retain the attributes of normal growth after being exposed.

    Opis:
    The aim of this study was to evaluate the practical feasibility of two forest regeneration methods using Scots pine Pinus sylvestris L. To this end, comparative experiments were established in the Złotoryja and Legnica Forest Districts. The site in Złotoryja had been clear cut, while the experimental plot in Legnica was established at a location damaged by wind in 2009 and cleared from wind throws and wind-broken trees before the experiment. Four different dates for sowing and two for planting were chosen in order to investigate the potential forest regeneration with respect to time. Both experiments were established according to the same design: a complete random block design with five replication blocks. To each plot we applied approximately 53 g (1.2 kg/ha) of seeds and planted 230 seedlings (10 200 seedlings/ha). In 2017, the height of the pine trees was recorded and their increment in height was measured in 2016 as well as 2017. A preliminary analysis of results was conducted using ANOVA for multiple experiments in order to identify significant differences and to then combine variables to form homogeneous groups to which the Duncan multiple range test could be applied. For growth traits, the ANOVA showed significant differences between experimental sights as well as a significant interaction of factors with the experimental site. In terms of planting, April was the most advantageous resulting in the greatest tree height in both forest districts, while in the Legnica Forest District the saplings planted in April also showed the greatest annual increments. Among the sowing dates, the most advantageous was the winter sowing, while the April sowing date produced the least desirable results. In conclusion, both sowing and planting are effective methods to establish pine cultures in coniferous forest. Furthermore, both methods may be performed at the currently recommended spring date, but they may also be postponed to summer and winter dates provided favorable weather conditions prevail.

Jednocześnie porównanie składników odżywczych wykazało nieznaczny wzrost zawartości azotu ogółem, w szczególności w obiektach z łubinem oraz nieznaczny spadek zawartości przyswajalnych form fosforu. Większą zawartość azotu amonowego i azotanowego stwierdzono w glebie obiektów z sosną i łubinem. Zawartość potasu i magnezu niepodlegała wyraźnym zmianom. Nie stwierdzono wyraźnych zmian zawartości mikroskładników w glebie porównywanych obiektów po zakończeniu wegetacji roślin.
    The research carried out on long-standing lupine and a common pine showed that the cultivation of these plants causes a slight lowering of soil acidity on the studied objects. At the same time the comparison of nutritional components revealed a slight increase of total nitrogen content especially in soil with long-standing lupine, and a slightly decreased content of available forms of phosphorus. The larger content of ammonia and nitrate nitrogen was observed in soil of objects soil of after common pine and lupine. The contents of potassium and magnesium were not clearly changed. The clear changes of micro-component content were not noted in soil of compared objects after ending of those plants’ vegetation.

Research results have shown that the proportion of heartwood in pruned pine stems was higher than in non−pruned ones. This was particularly noticeable after 24 years from the treatment while after 51 years this regularity was less distinct.

    Opis:
    The effects of pine and oak forest litter on mycorrhizal status of 2−year−old Pinus sylvestris L. seedlings grown in a bare−root nursery was investigated. The research was carried out in the nursery of Vilnius University Botanical Garden in Lithuania. Ectomycorrhizal communities were assessed by a combination of morphological and molecular techniques. Statistical analysis revealed significant effect of litter treatment on some growth parameters of seedlings: seedling height, needle dry weight and total seedling weight. The survival rate of seedlings was significantly highest for oak litter, intermediate for pine litter, and lowest for control soil. Pine seedlings were colonized by indigenous ecto− and ectendomycorrhizal symbionts. Seven mycorrhizal species (Suillus luteus, S. variegatus, Wilcoxina mikolae, Tuber sp., Tomentella sp., Cenococcum geophilum, Amphinema byssoides) were distinguished on the roots of pine seedlings as well as one ectomycorrhizal symbiont not identified to species level. In total, 6 mycorrhizal types were found in control soil, 5 in pine litter, and 8 in oak litter. Suilloid (S. luteus and S. variegatus) and Wilcoxina mycorrhizae were dominant on tested seedlings, irrespective of litter addition. Seedlings grown in untreated nursery soil were 34% colonized by W. mikolae, while suilloid mycorrhizae were dominant after litter treatment (81% in pine litter and 63% in oak litter). We may conclude that suilloid mycorrhizae are better adapted to the conditions related to litter addition than W. mikolae.

    Opis:
    Activity of soil dehydrogenase (DHA) was measured in the mineral soil in a forest stand of 15 to 16-year-old Scots pine (Pinus sylvestris L.) from geographically diverse populations, as an indicator of biological activity of soil microorganisms, in a provenance experiment in Poland. The pine populations originated from six European countries (Sweden, Russia, Latvia, Poland, Germany, France) and differed widely in aboveground biomass and productivity. Soil DHA during two growing seasons showed pronounced seasonal variability, which was significantly related to the fine root concentration of nonstructural carbohydrates. Higher DHA was found in soil under canopies of the central and southern European populations than in those from more northern parts of the Scots pine range. Significant positive correlation between soil DHA and aboveground tree biomass suggest that these patterns most likely resulted from differences in carbon dynamics and productivity among populations.

    Opis:
    The study was conducted in the Bydgoszcz Forest (Cierpiszewo Forest District) in the area of the lowest precipitation in Poland. In 4 plots (3 of rotary tiller and 1 – the comparative one – of plough soil preparation) measurement of Scots pines (Pinus sylvestris L.) and dry biomass of ground vegetation as well as soil investigations were performed. The best height and radial increment of pines were stated in the comparative plot (the soil cultivated by a plough) in spite of the distinct lowest of all plots soil moisture and nutrient stocks occurring there. The differences in plant growth can be explained by much more effective reduction of competition of ground vegetation in young plantations by a mouldboard plough than by a tiller. The results can also be explained by occurrence of unfavourable water conditions in rows prepared by a tiller during dry periods. The soil material in the rows is enriched in organic matter that results in increasing water repellence when it is dried. Rotary tiller should be recommended for soil preparation in the study area but on condition of successful ground vegetation removal from young pine plantations in some first years after planting.

    Opis:
    Celem pracy było określenie zdrowotności wybranych drzewostanów sosnowych Nadleśnictwa Szczecinek. Obserwacje zostały przeprowadzone w 2014r. na 15 stałych powierzchniach badawczych, zlokalizowanych na dwóch typach siedliskowych lasu (BMśw oraz LMśw) na gruntach leśnych oraz porolnych, reprezentujących klasy wieku od II do VI. Ocena stopnia uszkodzenia koron drzew została przeprowadzona na podstawie metody bioindykacyjnej opierającej się na trzech kryteriach: defoliacji, liczby roczników igieł oraz stopniu prześwietlenia korony. Analiza stanu zdrowotnego wykazała, iż 72,2% drzewostanów objętych badaniami było uszkodzonych w stopniu słabym, gdyż zostały zakwalifikowane do 0 i I stopnia uszkodzeń. Silnego oraz całkowitego stopnia uszkodzeń nie wykazano. Średni ubytek aparatu asymilacyjnego wyniósł 19,56%. Drzewostany wyrosłe na gruntach leśnych charakteryzowały się niższą średnią defoliacją korony drzew (18,19%), natomiast ubytek aparatu asymilacyjnego na gruntach uprzednio użytkowanych rolniczo wyniósł 20,82%.
    The aim of the study was to determine the health condition of selected Scots pine stands in Szczecinek forest district. Observations were carried out in 2014 on 15 permanent research plots, located on two types of forest habitat (BMśw and LMśw) on forest land and former farmlands, representing the age class II to VI. The evaluation of the damage to the crowns has been carried out on the basis of the bioindication method, which is based on three criteria: defoliation, the number of needle age–groups and type of tree crown attenuation. The analysis of health condition showed that 72.2% of the researched stands were damaged to the lesser extent, s they were qualified to the 0 and I degree of damage. The strong and total degree of damage has not been found. The average loss of assimilation apparatus was 19.56%. The stands growing on the forest land are characterized by a lower average defoliation of tree crowns (18.19%), while the loss of assimilation apparatus on land previously used for agriculture amounted to 20.82%.

    Opis:
    The aim of the study was to determine the rate of mineralization of needles in a pine stand in relation to site and to microbiological conditions occurring on dune slopes of contrasting aspects. The research was conducted in the old−growth pine forest overgrowing a latitudinally located dune in the Bydgoska Forest (N Poland). On contrasting dune slopes (northern and southern) rate of mineralization of pine needles was investigated in the 2−years experiment (2012−2014) with the litterbag method. Besides, following investigations were conducted in the middle part of both slopes: 1. dynamics of soil moisture and soil temperature were measured at a depth of 3 cm for 18 days during the 2013 growing season (interval of 2 weeks was applied) and 2. populations of bacteria and fungi were determined for all subhorizons of organic soil horizon (Ol, Of, Oh) as well as for a mineral horizon (AEs) of both soils. Weight loss of needles was found to be higher on northern than on a southern slope what was consequently stated for all 4 terms of taking measurements (6, 12, 18 and 24 months after placement of litterbags). The discrepancy has increased with time and after 2 years it equaled 14.7% when the loss was 61.1% for northern and 46.4% for a southern slope. It could be surprising that such differences were found in spite a sunny slope was characterized by stated in a study higher soil temperature. It should have a stimulating effect on mineralization of organic material; however a soil located on a southern slope was also found as much drier. Thus, the periodic deficiency of soil moisture was indicated as a limiting factor for occurrence of both bacteria and fungi on a southern slope due to the numbers of both groups of microorganisms were much lower on the slope than on a northern aspect. Conditioned by more favourable site parameters, higher number of microbial population occurring on a shadow slope could explain higher rate of mineralization of needles stated for the slope aspect. The moisture factor can be of especially high significance for microbial occurrence and activity and thus for litter decomposition just in dry inland dune ecosystems. It was concluded that in relatively monotonous pine forests overgrowing dry and poor in nutrients soils of inland dunes the slope aspect is an agent significantly differentiating both site and soil microbial conditions.

    Opis:
    There are no doubts that among numerous and very active insect species connected with scotch pine (Pinus sylvestris L.) very important role plays pine moth (Dendrolimus pini L.). In 2003 to „the battlefield” (Bydgoska Primaeval Forest – 2101,62 ha) with this pest air−borne equipment was designated PZL M−18 Dromader aircraft (in agricultural version equipped with 10 atomizers type AU 5000 Micronair). In tree crowns during 4 operation flights (total time 8 h 59 min.) ultra low volume (0,15 dm3 · ha−1) of insecticide Nomolt 150 SC (teflubenzuron) was introduced. Obtained effectiveness (96,0−99,5%) is the best indication of the position of this preparation in the whole arsenal of zoocides used in the forest stands control.

    Opis:
    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:
    Paper presents analysis of differences in conventional wood density of Scots pine measured at breast height regarding the geographical location of stands, forest habitat type, stand age and associated parameters such as density in the mid−length of the stem, density in the upper end of the stem and diameter at breast height. To investigate the impact of these factors, an analysis of covariance was used in accordance with two models specifically developed for this purpose. We found dependence of conventional wood density on the type of forest habitat and geographical location of the stand. The highest density was detected in dry coniferous forests, while the smallest in fresh mixed coniferous forests. Scots pine wood from Zielona Góra Forest (western Poland) characterised with the highest density, while from the Knyszyn Primeval Forest (eastern Poland)− with the lowest.
