    Opis:
    The aim of the study was to determine the influence of organic fertilization and mulching on the seedling vigour of European larch (Larix decidua Mill.) and occurrence of soil mites (Acari) in forest- and post-arable soils. Two different nursery experiments were carried out in the vegetation period of the year 2005 on light soils at two sylvan-natural regions of Poland. The first trial was conducted at Białe Błota near Bydgoszcz – on a brown podzolic soil. The second experiment – at Lipnik near Stargard Szczeciński – on an acid brown soil. The higher was the rainfall amount during the vegetation period, the lower was the seasonal irrigation rate supplied to European larch seedlings. Because of this the seasonal irrigation water rate applied at Białe Błota was higher than that at Lipnik. European larch seedlings grown on the forest soil were characterized by the increased height and the fresh mass than those cultivated on the post-arable ground. Seedlings grown in the forest soil on treatments mulched with litter were characterized by the increased height and the fresh mass of above-ground parts as compared to those cultivated on control plots (without mulching). Mulching with litter increased the number of mites, especially oribatid mites, as well as their species diversity. It can be recognized as the result of the positive influence of the mulching on the biological properties of the studied soils.

    Opis:
    Mountain forests are facing substantial changes. The need to adapt forest management to climate change is overlaid by the consequences of demographic changes that alter the form of land use profoundly. The European policy is aware of the challenges and supports mountain regions by the Regulation for Rural Developments and other strategies. Regional efforts of the Forest Authorities account for the changing ownership structure in order to ensure sustainable forest management and the provision of the dependent ecosystem services.

    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 this paper is to present a characteristic of loess permanent gullies, which form the branched erosion system, with the total length of almost 7.8 km, dissecting an erosion-denudation dry valley. Only 20%of the gully system catchment is cultivated as the result of steep slopes and considerable height differences up to 100 m. 80%of the catchment is covered by fir coniferous forest and Carpathian beech forest, and gully development is the result of intensive forest exploitation. Five types of gullies have been selected on the basis of the runoff directions, which are determined by the following: original relief, runoff concentration from fields, runoff concentration from fallplaces, skidding and course of forest roads used to carry a timber.

    Opis:
    The forest is becoming an important factor in maintaining the climate balance. Forest has a great influence on the regulation of global warming. In addition, forest plantations became the basis for conservation and recreation of biological diversity of flora and fauna. In connection with the aggravation of the ecological situation and the deepening of economic contradictions, the forest as a complex of resources for national security takes on special significance. The article examines the factors of changing the quantitative and qualitative characteristics of forest resources. The institutional problems of forest use and protection are considered. The analysis of joint management of forest resources in transboundary regions of Ukraine and Poland is given. Great attention is paid to assessing the assimilation potential of forest resources. The possibility of rational use of transegrain forests with the participation of international organizations is substantiated. The necessity of improving the ecological and legal relations between the European Union and Ukraine is substantiated.

    Na podstawie pomiarów uzyskanych ze stacji meteorologicznej LZD Siemianice średnia z wielolecia 1975÷2006 roczna suma opadów atmosferycznych na badanym obszarze jest równa 560 mm (tabela 2). W półroczu zimowym w badanym wieloleciu średnia suma opadów wynosi 210 mm. Wartość średniej sumy opadów w półroczu letnim w danym wieloleciu jest równa 350 mm. Maksymalna zmierzona roczna suma opadów wyniosła 958 mm, natomiast najniższa jest równa 434 mm. W omawianym wieloleciu średnia roczna temperatura na analizowanym obszarze wynosi 9,0°C. Średnia z wielolecia temperatura powietrza w półroczu zimowym jest równa 2,4°C, natomiast w letnim 15,5°C. Najniższa temperatura w wieloleciu w półroczu zimowym wyniosła -0,4°C, a najwyższa 4,6°C, natomiast najwyższa temperatura w wieloleciu w półroczu letnim wyniosła 17,1°C a najniższa 13,6°C.
    The research of water resource evaluation were carried out at three small forest catchment located at Wielkopolska region. G and G-8 catchments are located at Siemianice Forest Experimental Farm in southern part of Wielkopolska region. Hutka catchment is located at Zielonka Primeval Forest in central part of the region. The maximum water flow in analyzed G, G-8 ditches and Hutka water-course always appeared in winter half-years. Meanwhile water flow in analyzed watercourses were always significantly lower in summer half-years and periodically they disappeared. It was also indicated that increase of groundwater levels is strongly connected with water retention in winter half-years. Meanwhile decrease of groundwater levels and water content in soil caused by higher evaporation were observed in summer half-years which had significant role in water balances of these catchments. The research carried out in a different habitat conditions indicated the smallest changes of groundwater and total retention in swamp habitats: mainly in ash-alder swamp forest and moist broadleaved forest. Higher differentiation of water retention changes and groundwater levels was observed in moist mixed broadleaved forest, moist mixed coniferous forest, as well as in fresh mixed broadleaved forest and fresh mixed coniferous forest. It suggests the possibility of better usage of their retention capability. Optimum water level sustaining in forest habitat soils allows better usage of retain water was also indicated in the research, which is in accordance with forest needs and environmental protection requirements.

    Opis:
    This study concerned 26 forest stands with Douglas fir situated in Lower Silesia, Great Poland, Pomerania, Warmia and Masuria. Each stand was represented by 24 trees. From each tree an increment core was taken by Pressler’s borer. The principal components analysis showed that the first three principal components accounted for 73% of the variation of chronologies in total. The first principal component was the most convergent with the mean air temperature curve for January–March, the second with the total precipitation for June–August, and the third with the mean temperature for June–August. The first principal component always integrated the chronologies and decided on a similar rhythm of changes in the tree-ring widths. The annual variation of tree-ring widths was also affected by precipitation in summer (June–August), but this differentiated the chronologies. This was reflected by the dispersion of chronologies in respect to the eigenvectors of the second principal component. The third principal component also differentiated the chronologies. Separate groups were formed by the most eastern and the most western localities of the territory under investigations. Thus the Douglas fir growth reactions were mainly affected by the thermal and pluvial conditions of summer and, to a lesser, degree by the thermal conditions of winter. On the basis of these results it was possible to distinguish the dendroclimatically homogeneous regions in western and northern Poland.

    Opis:
    The calamity windstorm in November 2004 caused dramatic changes of land cover in the Tatra Mountains. The bora have destroyed then more than 12,000 ha of forest and principally affected the habitat structure in the Tatra National Park. The aim of this contribution is to quantify changes in forest fragmentation in 2000 and 2006. We present forest fragmentation maps related to the years 2000 and 2006. The CORINE Land Cover data layers CLC 2000 and CLC 2006 converted to raster format were used as the input data in the process of forest fragmentation assessment. Forest pixels were classified according to fragmentation indices measured within the surrounding landscape as the forest core, forest patch, forest edge, and perforated forest. Decrease of the compact forest areas (forest core) by about 9% was recorded. On the other side, increased percentage of disrupted forest areas was observed. Decrease of the area of the CLC forest classes (classes 311, 312 and 313) on land cover maps from 2000 and 2006 was connected with an increased number of transitional woodland/shrubs polygons (CLC class 324). These results suggest a temporary fragmentation with possible forest regeneration. On the other hand, forest destruction in the National Park facilitated the development of travel and tourism (new hotels, ski parks, etc.). An increased number of construction sites (CLC class 133) indicate that an urban sprawl associated with a permanent forest fragmentation can be also expected in the future.

    Opis:
    The study investigates the intra-population variability of the growth and quality traits of Norway spruce populations from Bliżyn and Zwierzyniec Lubelski. The two populations are included in the IUFRO 1972 experiment and exhibit a high growth dynamics and a narrow crown form. The research was carried out on the experimental plot established in 1996 in Chrosno (Kutno Forest District) using 8228 two-year-old seedlings planted in a single-tree plot design at a spacing of 1.5 × 1.5 m. The seedlings represent 191 open-pollinated families, among them 93 families of Norway spruce from the Bliżyn region and 98 families from the Zwierzyniec Lubelski region. The height, height increment and DBH of trees were measured periodically, and some quality traits were assessed. The last results come from the measurements done on the trees aged 10 years. It was found that the differences between the two populations of Norway spruce are statistically nonsignificant but both of them show wide within-population variability. This suggests that they have the potential to flexibly respond to future changes in the growth conditions or to seed transfer to other seed zones. Survival in the environmental conditions of the experiment was independent of family.

    This paper analyses wave attenuation in coastal mangrove forests in Vietnam. Data from 32 mangrove plots of six species located in 2 coastal regions are used for this study. In each plot, mangrove forest structures and wave height at different cross-shore distances are measured. Wave height closely relates to cross- shore distances. 92 exponential regression equations are highly significant with R2 >0.95 and P val. <0.001. Wave height reduction depends on initial wave height, cross-shore distances, and mangrove forest structures. This relationship is used to define minimum mangrove band width for coastal protection from waves in Vietnam.

    Opis:
    The following research on plant litterfall mass, dynamics, structure and chemistry was conducted from 2012 to 2014, on a 40- to 86-year-old stand of black alder (Alnus glutinosa) growing in a headwater area of the upper part of the valley of the Kamienna Creek (Middle Pomerania). Litterfall was collected every month with 20 circular traps, dried untill constant weight, divided into fractions, weighed and analyzed. The annual amount of litterfall deposited on soil during the study period ranged from 3482.5 to 4106.9 kg·ha-1, showing a dynamics pattern typical of temperate decidous forests. Leaves constituted the major fraction of litter with share of between 78.0 and 81.6% in its total mass. The contribution (in %) of twigs was 4.9-5.6, flowers 2.8-8.3, fruits 0.2-0.9 and other components 7.6-9.2. The relatively stable environmental conditions of headwater areas and the absence of disrupting factors during the study period were reflected in the low temporal variability of litterfall mass, dynamics and chemical composition of its individual fractions. The average annual pH of litterfall was 4.33-4.57. In general, litter was relatively rich in nitrogen and calcium but poor in phosphorus, potassium and magnesium. The content of Fe, Al and Mn was characteristic for these elements and low when compared to the other macroelements. The low contents of Cu and Zn confirm limited anthropogenic contamination of the investigated ecosystem with these metals. The annual return of the elements to the soil formed a series C>N>Ca>K>Mg>P>Mn>Fe>Al>Zn>Sr>Cu. A relatively large influx to the soil was noticed for nitrogen and calcium. Meanwhile, it was low for potassium, magnesium and phosphorus.

    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:
    This study investigates the effect of climate variability on the phenotype, leaf litter decomposition intensity and seedling spread of alien red oak (Quercus rubra L.). Twenty-eight red oak forest stands located in Lithuania were evaluated. Indirect climate change indicators such as continentality were used in the analysis. Simulation of climate warming was achieved using an agro sheet cover. According to the results, the morphological traits of red oak stems in the maritime regions (warmer winters) do not differ significantly from those of red oaks stems in the continental areas of Lithuania (colder winters, more frequent spring frosts). Red oak leaf litter under an agro sheet cover (warmer conditions) decomposes at almost the same intensity as without the cover (natural conditions). The red oak seedlings spread 100 m or more irrespective of continentality. These results showed indirectly that climate change will not affect red oak stem quality or microorganism activity in the process of leaf litter decomposition. Red oak will thus remain as an invasive species, threatening composition change in native forests.

    Opis:
    The author investigated a 0-3 cm layer of two forest brown soils: brown acid and brown leached. These forest soils were under handsome beech trees (Fagus sp.) between 100 and 120 years old. The author compared the chemical properties of the soils. The soil existing near the tree trunk (1 m2 of surface, strongly washed by rain water polluted by chemical substances) and the soil existing under the tree umbrella (40 m2 of surface in the area of the tree-tops, washed poorly by rain water). This comparison showed changes in these properties, dependent upon the degree of atmospheric contamination. It was found that, at the same level of atmospheric contamination, higher changes of properties were found in brown leached soil than in brown acid soil. Less acidified soils (with alkaline or neutral pH reaction) are more suitable in these researches. The investigations of the forest soil layer 0-3 cm (12 soil profiles) showed that changes in their chemical properties in relation to tree trunk-tree umbrella can be the basis of assessment of the degree of atmospheric contamination.

    Opis:
    Concentration and profile distribution of heavy metals was investigated as contamination indicators of the forest soils formed from glacial deposits of the South Podlasie Lowland. The study was carried out on thirteen soil profiles situated a hundred meters from the road. The highest content of heavy metals was found in the organic horizons of the investigated soils. The mean content of Mn, Zn, Cu, Pb, Ni, Cr in the investigated soils were: 556.7, 72.9,15.5, 63.5,13.8, 16.5 mg/kg d.m. of the soil, respectively. In the mineral-organic and mineral horizons of the investigated soils heavy metals were present in quantities which were close to natural. The podzol soils, podzols and rusty soils developed from sands contain less heavy metals than the soils lessivés, black earth and deluvial soil. The Mn, Zn, Cu, Pb distribution in the soil profiles is influenced by the soil forming processes. The distribution index of the examined metals distribution in the genetic horizons testify to it.

    Opis:
    Gap regeneration in a European beech (Fagus sylvatica L.) forest reserve was analyzed in relation to within-gap resource heterogeneity and ground vegetation competition. The study was carried out in two one-hectare permanent research plots (PRP) which included five smaller research plots (RP) encompassing two large gaps (500–700 m2), two small gaps (300–400 m2), and location under canopy. The coverage of woody regeneration, ground vegetation, dead wood, seedling density in eight height classes, characteristics of dominant trees of the beech regeneration, and the total thickness of holorganic horizons were measured. Soil moisture and light conditions were also assessed in selected sample plots. The relative direct and diffuse light was estimated by hemispherical photography. Small gaps showed both the highest cover of tree regeneration and the highest density of individuals per hectare. Slightly less regeneration was recorded in large gaps, while under closed canopy, regeneration densities were 5–10 times lower than in small gaps. Beech regeneration cover and the size (diameter and height) of dominant beech seedlings were positively related to relative diffuse light and negatively related to ground vegetation cover. The latter was positively related to diffuse light and soil moisture content. A pronounced statistically significant contrast in the cover and size of beech regeneration in relation to micro-site conditions (diffuse light, cover of graminoids) was only confirmed between sample plots located below canopy cover and those within gaps. Graminoids, in particular Calamagrostis epigejos L., occurred mainly in the large gap centre and along the southernmost edge of the large gap, increasing competition for resources here. The cumulative cover of ground vegetation and regeneration was relatively low (9–56%) compared with more mesic natural beech forests. The indicated negative influence of direct light at the northern gap edge suggests that extension of gaps on comparable sites in managed forest should not proceed in this direction.

    Opis:
    In fall 2018 and 2019, we assessed colonization by fungi on Douglas fir trees [Pseudotsuga menziesii (Mirb.) Franco], white pine (Pinus strobus L.), and red cedar (Thuja plicata D. Don.) on selected experimental plots of the former Prussian Experimental Station, where nonnative tree species were introduced from North America over a century ago. The presence of sporocarps on trunks, root collars, and stumps as well as the litter layer in the soil within a radius of 0.5 m around the trunk of the tree was determined. Additionally, the volume of dead wood on the forest floor of the entire plot was assessed. We recorded numerous fungi on trees and stumps as well as in the litter and soil. For the 31 plots in 12 forest districts, we determined 745 sporocarps of 48 taxa, with 335/19 on the wood of P. menziesii trees and stumps, 377/15 on P. strobus, and 33/6 on T. plicata trees. The highest share of trees with various trunk damage levels was found for T. plicata (70.3%) and the lowest for P. menziesii (6.2%). Among the root parasitic fungi, Heterobasidion sp. and Armillaria sp. were found, especially on the collars and stumps of T. plicata and P. strobus; we did not find basidiomata of both pathogens on P. menziesii. The volume of dead wood within the P. menziesii plots averaged 7.1 m3/ha, whereas in T. plicata plots, it was 56.3 m3/ha. We identified 10 taxa that have not been reported in association with P. strobus for Poland (Cylindrobasidium laeve, Dacrymyces sp., Exidia pithya, E. saccharina, Gymnopilus pnetrans, Leptoporus mollis, Mycena sanguinolenta, Tapinella panuoides, Trametes versicolor, and Xylaria hypoxylon) and three taxa (Exidia pithya, Leptoporus mollis, Serpula himantioides) associated with T. plicata.

    Opis:
    In 2005, in the administrative district (powiat) of Garwolin (the Province of Mazowsze), the samples of forest, cropland and fallow land soils were collected from three depths: 0-3 cm, 3-7 cm, 7-12 cm. The litter from the sampling sites located in forests was also collected for studies. In the samples, the contents of isotopes 137Cs and 40K were measured. The highest amount of 137Cs was measured in litter and the upper layer of forest soils; the content of the isotope decreased in deeper layers of the soil. Forest soils were the richest in 137Cs; fallow and cropland soils contained less of this isotope. The content of 40K in forest and fallow land soils did not depend on the depth from which the samples were collected. The highest amount of 40K isotope was found in arable soil, the lowest - in forest soils. The content of 137C in the soils decreased as the soil reaction increased but rose at higher organic carbon content. The content of 40K isotope correlated negatively with the soil reaction and with the content of sand fraction but it correlated positively with the content of clay fraction.
    W 2005 r., w glebach powiatu Garwolin (woj. mazowieckie) z trzech poziomów: 0-3 cm, 3-7 cm i 7-12 cm pobierano do badań próbki gleb leśnych oraz nieużytkowanych i użytkowanych rolniczo jako pola uprawne. Dodatkowo w punktach poboru gleb leśnych pobrano do badań ściółkę leśną. W próbkach oznaczono zawartość izotopów 137Cs i 40K. Największą zawartość 137Cs zmierzono w ściółce i powierzchniowej warstwie gleb leśnych, w głąb gleby zawartość izotopu się zmniejszała. Najbardziej wzbogacone w 137Cs były gleby leśne, gleby nieużytkowane rolniczo i pola uprawne zawierały mniejsze ilości tego izotopu. W wierzchnich warstwach gleb leśnych i nieużytków zawartość 40K nie zależała od głębokości poboru prób, natomiast była zależna od sposobu użytkowania gleby. Największe ilości izotopu 40K zmierzono w badanej warstwie gleb ornych, najmniejsze w glebach leśnych. Zawartość 137Cs w badanych glebach zmniejszała się wraz z ze wzrostem odczynu gleby i wzrastała wraz z zawartością węgla organicznego. Zawartość potasu-40 była skorelowana ujemnie z odczynem gleby i zawartością frakcji piasku oraz dodatnio z zawartością frakcji iłu.

    Opis:
    The aim of undertaken research was recognition the reasons of dying out the common juniper Juniperus communis L. ssp. communis population in the forest nature reserve “Jałowce” (Pomerania). Applied methods of dendrochronological analysis let to determine the age of juniper-stand in the reserve and describe the influence of climatic conditions on its growth. Obtained results testify to Juniperus communis chronology with signature WIE collected from 17 individual sequences which numbered 102 tree ring width and represented a time span 1903 to 2004. Such results described the juniper-stand in the reserve as ageing population with the oldest specimen at age 98 years. However, the last several years were characterised by the lack of strong growth depressions typical for earlier time periods with tree ring width ranged 0.7–1.0 mm (themean annual tree ring width amounted to 0.85 mm), but the visible symptoms of degeneration and dying out of protected common juniper population intensified probably because of its age.

    Opis:
    The study of tree-hole breeding mosquitoes was carried out in the tropical rainforest of Imo State Nigeria (two rural areas and two forest reserves in some parts of Orlu Senatorial Zone) between May – October 2002. Using standard entomological procedures, two macrohabitats (natural tree-holes and bamboo traps) and two microhabitats (leaf axils of cocoyams/pineapples and leaf axils of plantain/banana) were sampled for various mosquito species. Mosquitoes were recovered from all the various biotypes sampled. Types of mosquitoes species encountered, their relative abundance, as well as genera varied signifi cantly during the study (p<0.05). Four genera of mosquitoes: Aedes, Culex, Anopheles and Toxorhynchites were recovered while 16 species of mosquitoes encountered include: Aedes aegypti, Ae. africanus, Ae. simpsoni, Ae. albopictus, Ae. stokesi, Ae. taylori, Ae. apicoargenteus, Culex quinquefasciatus, Cx. nebulosus, Cx. trigripes, Cx. decens, Anopheles gambiae, An. funiestus, An. coustani and Toxorhynchites viridibasis. Most of the mosquitoes showed oviposition preferences for one or more habitats. The presence of Ae. africanus, Ae. simpsoni and Ae. aegypti indicate that the study areas were at risk of yellow fever epidemic. The presence of Anopheles and Culex species ensured endemicity of malaria and fi lariasis, while the recovery of Ae. albopictus in this region suggests a possible outbreak of dengue fever in future if not properly controlled.

    Opis:
    Roztocze - the picturesque region abounding with unique landforms and pre-Quaternary rock outcrops, is characterized by high geodiversity. Silicified wood fragments are the specific peculiarities of this area and its unique geological heritage. The petrified wood became the geoturistic symbol of this region. Numerous historical buildings and monuments, such as churches, roadside crosses and thumbs (mainly from the 18-19th centuries), made of local rocks, are the remnants of history of three societies: Polish (Roman-Catholic), Ukrainian (Greek-Catholic) and Jewish, which coexisted in the Roztocze region until the Second World War. These traditions and remnants constitute the diverse cultural heritage of this area. Extraordinary geodiversity, natural and cultural values as well as social circumstances gave rise to the establishment of the Stone Forest Geopark in Roztocze, promoting the geological heritage, with special regard to the petrified wood. High scientific and educational values of more than 150 geosites recorded in this region create the advantageous perspectives ofgeotourism development as well as comprehensive ecological education. Eight geotouristic trails are planned in the Geopark. The expansion of the Geopark onto the Ukrainian part of Roztocze seems to be possible in the future. The transboundary Geopark, fulfilling its statutory objectives, will be able to join the European Geopark Network.

    Opis:
    The aim of this paper was to assess differentiation in the total content of Cu, Zn and Mn under the influence of water erosion. The present author investigated parent material, eroded soils and delluvial sediments of a small arable-forest catchment of the moraine zone in West Pomerania. The average content of heavy metals in the parent rock (boulder light loam) were assumed as geochemical backgrounds of Cu, Zn and Mn. It was found out that erosion process caused differentiation in heavy metals. Zinc was the most mobile in this transportation; Mn was not sensitive to it. Delluvial sediments from arable (drainage) depressions had a clearly lower content of Cu and Zn than the parent material. It was also noted that Cu and Zn content in the forest area was lower than in the arable area of a similar relief and soil composition. Mn content was always higher in the arable soils. Soil-forming processes influenced differentiation of heavy metals in the vertical soil profile. The humus and Bt horizons (accumulation of silicate clay) were enriched with heavy metals. A decrease of heavy metal content was noticed in the eluvial horizon (Eet - outwash of silicate clay). The humus horizon of the investigated soil had, a natural (not increased) content of Cu, Zn and Mn.

    Opis:
    The Sauerland region of southern Westphalia has the most economic stands of Norway spruce in the state of Northrhine-Westphalia (Germany). As shown by historical research and genetic analysis, the seeds for these stands were imported from Thuringia around the year 1880. Therefore, the two states are collaborating closely to secure the genetic variety of the spruce and develop new sources of seed supply. The survival of the Hochsauerland Norway spruce is now under threat: these stands have already been harvested or are due for harvesting shortly, in addition, many of the older stands were destroyed by the gale "Kyrill" in 2007, and only a few stands have remained. Since its foundation, the Forest Gene Bank of Northrhine-Westphalia has taken the following measures to preserve the gene pool of the Hochsauerland spruce and conserve it in the long term: storage of seed from 100 representative trees in all the most valuable stands of spruce (since 1985); establishment of seed orchards; and establishment of replacement stands. Thanks to those measures, the genetic information of the Norway spruce stands of Thuringian origin has been secured, and substantial stocks of seed are available for reforestation.

    Opis:
    The juvenile height growth of Norway spruce (Picea abies (L.) Karst.) was studied in 1095 spruce provenances included in the IUFRO inventory provenance test of 1964/68. Trees growing on the experimental site established in Krynica in the Beskid Sądecki Mts. (Carpathians) were measured at ca. 3-year intervals in the period 1969-1988, from the age of 6 years (i.e. 2 years of planting) to 25 years. The variability of tree height in this spruce population was assessed on the basis of the means expressed in units of standard deviation, calculated for each provenance and each geographical region of Krutzsch in successive years of measurement. Using the standardised units made it possible to characterise the dynamics of spruce growth in provenances from 95 geographical regions representing the whole European range of the species. The effects of geographical region, tree age and their interaction on the variability of height growth within this range were estimated using multi-way analysis of variance with replicated measurements. The regions showing similar spruce growth trends were grouped by using hierarchical cluster analysis. The results on the juvenile dynamics of height growth showed that spruce provenances from various geographical regions of Krutzsch differ significantly in their genetic reactivity. Based on this, several groups of regions were identified: (1) regions with average or weak but stable spruce growth characterised by no significant effects of age or genotype × age interaction in the whole measuring period, or regions with height growth improving with age; (2) regions of spruce provenances constituting a selection elite, with very good height growth in the whole measuring period or in its later part, characterised by no G × A interaction; (3) regions with varied genetic reactivity of height growth dynamics in the juvenile period, and regions of Scandinavian populations with poorest height growth in the whole measuring period. The studies proved that spruce provenances from the regions of Štiavnické Pohorie, Low Tatras (Slovakia), Masurian Lakeland, Augustów Lakeland, Podlasie, Silesian Beskid Mts., Beskid Żywiecki Mts. (Poland), Jutland (Denmark), Bihor Mts., Transylvania, and Eastern Carpathians (Romania) have a high selection value.

    Opis:
    The aim of the studies was to check the usefulness of ITS1/2 rDNA and 18S rDNA regions in the molecular investigation of forest soil microbiota structure. Soil studied, originated from a 1−year−old plantation and a 40−year old stand of Scots pine located in Bierzwnik and Międzychów forest districts located 200 km apart. The hypothesis assumed that both approaches lead to the discovery of abundant microbiota communities with different structures and with rare common species. The environmental DNA was extracted with a Power Soil ® DNA Isolation Kit from two soil samples in each site. The ITS1/2 rDNA was amplified with specific primers ITS1 and ewfitsrev 1, and 18S rDNA with universal primers NS1 and NS2. PCR products were cloned into pGEM−T Easy. Inserts were primarily selected in blue/white screening on a X−gal medium. Representative clones were further selected in two separate RFLP analyses with HhaI and BsuRI restriction enzymes. Representative clones purified and sequenced using the Sanger Method in the DNA Research Centre (Poznań). Each sequence was identified to the lowest taxonomic rank. Ninety to 233 clones with DNA of 5−44 taxa including 3−37 taxa of fungi were obtained from 4 samples of soil. After application of ITS1/2 rDNA and 18S rDNA, the fungal DNA was detected respectively in 89,60−100,00% and 11,77−64,8% clones and the number of fungal species detected was respectively 12−37 and 3−19. Fungi were represented by four orders: Chytridiomycota, Zygomycota, Ascomycota and Basidiomycota. Both primers also amplified also DNA of other organisms (mostly from Animalia and Protista Kingdom) represented by 0−9 taxa. If compared, the application of forest soil microbiota structure with ITS1/2 rDNA and 18S rDNA led to detect a lower abundance of fungi and a bigger abundance of other organisms. Considering the higher number of clones and taxa recognized, the region of ITS1/2 rDNA was more effective in the studies of the soil microbiota structure. The region of 18S rDNA was efficient in local detection of Chytridiomycota and Zygomycota and of rare species of fungi from Ascomycota and Basidiomycota. Despite the deficiency of NCBI database the use of the 18S rDNA region in studies on fungal community the region should be included in molecular studies of fungal diversity. It is concluded that studies on the biodiversity of soil microorganisms need the application of a few independent methods of detection and identification.
