    Opis:
    The ‘National Forest Policy' (PLP), adopted by the Council of Ministers in 1997, is the main document setting out directions of forestry development in Poland. It defines goals and priorities of forest policy, describes organizational, economic and legal conditions of its implementation and specifies expected results. While the natural, social, economic, institutional and legal environ− ment has significantly changed over the last 20 years, the PLP has not been revised and updated, also in terms of Poland's international commitments resulting from the MCPFE (currently Forest Europe) process. The aim of the paper is to analyse directions of forest policy development under the Forest Europe after 1997, i.e. when the PLP came into force, and to indicate needs to update the issues contained in this document. The study focuses on goals and priorities of the MCPFE defined in resolutions and decisions adopted on conferences held from 1998 (Lisbon) to 2015 (Madrid). Overall 15 main directions on forest policy development were identified (tab. 2). They were then compared with the priorities defined in the PLP to identify issues to be updated in the context of the European forest policy change. The study shows that many of the priorities of European forest policy has not been reflected in the PLP (tab. 2). These include, among others, adapting forests to climate change and enhancing their mitigation potential, enhancing economic contribution of the sustainable forest management (SFM) into rural development, enhancing the role of the SFM in a green economy, securing participation of all stakeholders in forest−related decision−making process, improving communication in forestry and developing cross−sectoral cooperation of forestry. Many of the forest−related issues have been, however, included in numerous strategic documents of environmental protection, biodiversity conservation, rural development, economic development or energy policies after 1997. In that way many goals and priorities defined under the Forest Europe are very dispersed in Polish policy documents of different forest−related sectors and it raises reasonable concern that some inconsistencies and contradictions between them may occur. It may also indicate that the forest sector is getting more and more marginalized in socioeconomic and political space, as forest policy goals are defined and achieved within other areas. We therefore recommend to continue efforts to adopt the National Forest Programme and launch a participatory, holistic, inter−sectoral and iterative process of forest policy planning, implementation, monitoring and evaluation.

    Opis:
    The main interest of the FOREST EUROPE (formerly known as the Ministerial Conference on the Protection of Forests in Europe, MCPFE) was to introduce the principles of sustainable forest management in Europe. Topics that linked forestry with the global conventions and agreements were addressed at ministerial conferences. These topics were called priorities. A comparison of ministers speeches from the subsequent conferences with content of the international agreements and documents allowed the selection of 24 priorities (tab.) that appeared 627 times at the conference proceedings. Priorities appearing at the MCPFE process were analysed with the aim of identifying trends of their occurrences. Cluster analysis allowed to categorise different conferences according to their similarities in terms of the emerging priorities (fig. 1). The most closely related were the conferences held in 1998 and 2003 as well as the one held in 2007 and 2011. The conference held in 1990 differed the most from others. The same technique was used to explore similarities and to categorise priority groups. Five most interconnected priority groups were selected (fig. 2). As no permanent linkages between different priorities existed, it was difficult to establish priority groups that were discussed during the following conferences. It was possible, however, to distinguish priority groups that were similar in terms of their appearance, duration or disappearance during the subsequent ministerial summits. Some thematic priorities seemed to be important for individual countries in the longer term than period between the conferences, and those continued to appearing at the ministers speeches during the subsequent summits. The application of statistical methods based on the cluster analysis allows for an appropriate analysis of the MCPFE process.

    Opis:
    The objective of this study was to estimate the edge effect on the species richness in agriculturally maintained forest-grassland boundaries of coniferous forest and to determine how species respond to a forest edge. We hypothesised that species number, cover of herbs and mosses is higher in the edge, and species penetrates from nearby grasslands into forest interior. The study was conducted in the Southwestern Lithuania. The edge effect on overall herbaceous species composition of coniferous forests was evaluated by Canonical Correspondence Analysis. The species richness of herbs and mosses in the coniferous forest was highest in the forest edge and declined towards interior. The highest decrease in the number of species occurred within 0 to 5 m to the edge. The highest cover of herbs and mosses was in the forest edge and decreased towards the forest interior. CCA biplot showed a good correlation of overall species composition and the distance to the forest edge. Distribution of species along edge to interior gradient depended on the species response to different ecological factors. Ellenberg value of light was higher in the edge. Ellenberg value of nitrogen was higher in the forest interior.

    Opis:
    The paper deals with the dynamics of structure, diversity and growth of natural pine stands without direct human impact during the ten-year period in Nature Reserve (NR) Kostelecké bory, Czech Republic. The objective was to determine the main characteristics of the spontaneous development of Scots pine (Pinus sylvestris L.) forest stands in relation to their naturalness, ecological stability and adaptation to climate change and air pollution stress. Horizontal and vertical structure and species diversity of the tree layer, dead wood and natural regeneration of each permanent research plot (PRP) were evaluated (n = 6, 50 × 50 m /0.25 ha/, Northern Bohemia, 410–425 m above sea level). The average ring series of PRPs were correlated with the climatic data (precip- itation, temperature) according to individual years from the Doksy climatic station, and the air pollution data (SO2 in 1988–2015, NOX and AOT40F – ozone exposure in 1992–2015) from Radimovice station. In 2016, the stand volume increased by 26.0% to 136 m3 ha−1 (108 m3 ha−1 in 2006) and the volume of dead wood increase by 127.2% to 27 m3 ha−1 (12 m3 ha−1 in 2006). The horizontal structure of tree layer and natural regeneration was predominantly aggregated to random. More distinct changes in biodiversity and structural characteristics occurred in the natural regeneration (21.5%) compared to tree layer (2.8%). The precipitation had a significantly higher effect on radial growth compared to temperature. The lack of pre- cipitation in growing season and high temperature in previous autumn and winter were limiting factors for growth. Climatic factors had significant effect on diameter increment in July of the current year (P < 0.01) and June of the current and previous year (P < 0.05). Radial growth was negatively correlated with SO2 con- centrations (P < 0.01) and ozone exposure (P < 0.05). NOX concentrations had low effect on radial growth. The natural stand dynamics had positive effect on biodiversity and functional integrity of natural pine eco- systems.

    Opis:
    In this study, we examine the pattern of occurrence of Impatiens parviflora in Central European oak forests over time and its ecological requirements within these types of communities. Research was based on phytosociological data collected in 3776 relevés. A modified TWINSPAN algorithm were used to distinguish the groups of oak forests. The ecological preferences of the I. parviflora and studied communities as well as differences between invaded and non-invaded vegetation plots were analyzed using mean weighted Ellenberg indicator values (EIVs). Finally, both the temporal pattern of I. parviflora participation and changes in its coverage in the studied communities were analyzed. Our study confirmed a high adaptability of this species with respect to temperature, moisture, soil reaction and nutrients and determined its broad ecological optimum in oak forests. However, it also revealed both a greater sensitivity of some communities within Central European oak forests to the invasion of I. parviflora and differences in habitat conditions between invaded and non-invaded vegetation plots. This suggests that the habitat niche of I. parviflora within oak forests is not accidental. The analysis of temporal changes in the frequency of I. parviflora confirmed a 20% increase in relevés over the last 50 years. However, we did not identify any statistically significant rise in the coverage of I. parviflora in oak forests specifically during the studied period.

    Opis:
    The paper provides a detailed characterisation of Norway spruce stands in the Ukrainian Carpathians. The majority of natural spruce stands in Ukraine occur in Polesie, while artificial regeneration is spread all over the country. The most densely forested part of Ukraine is the Carpathian region with 41.1% of forest-covered area (2.1 million ha). Spruce-dominated stands occupy about 700 thousand hectares (30%) of the forested area of the state forest fund in the Ukrainian Carpathians, and another 10% of the mixed forests contain 10 to 30% of spruce. Besides pure spruce stands, there are beech-spruce, beech-fir-spruce, and cedar-spruce stands. The most productive stands (750-900m3 stem wood per ha) grow in the middle and lower parts of slopes at 1100-1200 m a.s.l. which have favourable soil and climate conditions. Since the second half of the 20th century, spruce stands in the substantial part of the Ukrainian Carpathians have declined under the influence of complex anthropogenic and natural factors. Although the present condition of most spruce forests in this region remains satisfactory, the degradation processes and the ban imposed in 2006 on planting spruce on non-spruce forest sites (in state forests) may decrease their area in the longer term.

    Opis:
    Forest communities dominated by noble broad-leaved trees (maple, lime and ash) in Europe are of elevated scientific and conservation interest for the European Union. In this paper, we first present a synthesis of the maple and ash forests in peninsular Italy. By classifying these forests, we distinguish seven main groups for the territory, which only broadly match the syntaxa proposed in the literature. The variability of the Apennine data is then analysed floristically and phytogeographically (using chorological components) in a central-southern European context, using numerical classification, INSPAN, and direct ordination of several synoptic tables. These analyses allow us to identify six different groups of European Acer-Fraxinus communities. Canonical Variates Analysis (CVA) of the geographical components confirms the existence of distinct phytogeographical groups. In particular, we highlight the clear distinction between central European (including the Alps) and southern European coenoses. Among the latter there was a clear floristic and chorological distinction between Balkan and Apennine groups. These results reflect the biogeographical subdivisions of Europe, but do not support the syntaxonomical schemes proposed by other authors, which are based only on floristic-ecological information or (recently) use a smaller data set of Italian relevés. This study also shows that syntaxonomical schemes above the association level should pay more attention to phytogeographical aspects rather than focus on floristic-ecological information alone, in order to propose models that are of value on a geographical scale.

    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:
    Three populations of Norway spruce from ecologically extreme environments in Slovenia and Bosnia and Herzegovina were examined for genetic polymorphism. The spruces there grow in specific forest communities (Sphagno-Piceetum) which represent the remnants of the post-glacial vegetation. The aim of the study was to search for similarities in the genetic variation among populations adapted to such conditions. In total, 10 isoenzyme systems involving 16 gene loci were analysed. The results showed differences in genetic differentiation at loci Got-B, Skdh-A and 6-Pgdh-C between the two Slovenian populations and the Bosnian population, but also indicated an interestingly close relationship between the Slovenian population Pohorje and the Bosnian population Nišići.

    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.

    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:
    Two provenance experiments with Norway spruce in Slovakia were used to reveal trends in the behaviour of provenances after their transfer. Regressions between the average height and survival of provenances and the differences between the geographic and selected climatic characteristics of the place of origin and provenance plots were significant for most of the characteristics tested. Data from the experiment with Polish and Slovak provenances from 1972 indicated that transfer into warmer regions with a longer vegetation period results in improved height growth and survival, with the exception of survival at initial stages. The experiment from 1964 with a broader altitudinal range of provenance plots, but with unadjusted latest measurements at individual plots available, revealed the best height growth of Slovak Norway spruce provenances after their transfer to sites with the mean annual temperature approximately 1°C higher and with the vegetation period 12 days longer than at places of origin. Transfer into lower altitudes, a warmer climate and a longer vegetation period improved survival. In both experiments, transfer to areas with increased rainfall had a negative effect on growth, which is probably associated with the fact that provenances are not able to exploit additional precipitation for the growth in areas with a colder climate and a shorter vegetation period.

    Opis:
    The quality assessment of spruce seeds consists mainly in determining their germination capacity, including germination rate (speed), but also purity and weight. Internationally recognised methods are listed in the ISTA Rules for Seed Testing which also specify test conditions. Some countries such as Poland use modified methods. Apart from providing information about the purity of a species, purity testing can also identify the proportion of winged seeds in each seed lot. Germination tests yield data on the maximum germination potential of a seed lot which are used to compare the quality of different lots and to establish the field sowing values. This paper presents the methods used for assessing the quality of Norway spruce seeds, and discusses their advantages and disadvantages and the problems that need further investigation.

    Opis:
    In the last decades, clone testing has become an important component of the long-term breeding and seed orchards for Norway spruce in Sweden. For more than three decades, considerable resources have been spent on testing clones intended for clonal forestry, but the Swedish forestry never saw it worth to pay the added cost involved in the added gain. The efforts, however, resulted in many clone trials and developments in the technique for clone production and propagation. Theoretically, clone testing is faster and cheaper than progeny testing and more reliable than selecting individuals forwards. Nowadays, the main line in long-term breeding is to make crosses between the best trees and test-cloned full-sibs as a recruitment population for long-term breeding and seed orchards. Since controlled crosses are a bottleneck for long-term breeding, a possibility is to rely on wind pollination (Breeding Without Breeding; BWB) in trials for testing clones. The seed parent is known, and that the pollen parent is a desirable genotype can be checked by molecular markers. BWB has the potential to eliminate the waiting time between selection and recombination, which is particularly important in a late and irregularly flowering species such as Norway spruce. Clone testing ensures that the breeding values are known from the same tests as those used for BWB. Another option for BWB is to place in seed orchards a few ramets of clones belonging to the breeding population, but normally not deserving such a use, with the hope that their presence will make it possible to rely on wind pollination to recombine the whole breeding population.

    Opis:
    The abundant flowering, observed in 2004 in a model outbreeding seed orchard established in Kórnik, Poland, promoted crossing between clones of five geographically distant populations of Norway spruce. The clones were selected from a group of ca. 1100 provenances participating in the international IUFRO 1964/68 experiment and performing best in terms of growth traits and adaptability. In the seed orchard, 91.3% of clones and 64.1% of grafts produced female and/or male strobili. Statistically significant differences between the clones were only found in the number of mature cones produced. The mean number of mature cones in individual clones was also significantly correlated with the latitude of the place of origin of maternal populations (r = 0.88, p = 0.047). The nearly equal percentages of clones representing each of the five populations in the outbreeding seed orchard (from 23.2 to 17.5%) resulted finally in the highly unequal production of full seeds by each population (from 62.9 to 0.7%). These data provide evidence to suggest that the level of genetic diversity in the progeny, expected from the number of growing clones, diverges from the level resulting from the contribution of clones to the full seed production which is an effective measure of the genetic composition of progeny. To avoid this divergence, an outbreeding seed orchard could be established with unequal proportions of clones from different provenances, considering the knowledge of their flowering phenology, and individual variation in flowering and cone production.

    Opis:
    At present, Norway spruce stands occupy 22% of the total forest area in Lithuania. Most of them are located in the northeastern highland (Žemaitija) and the central part of the country. 25% of the spruce-dominated stands are pure, the rest are mixed. Natural calamities like storms, droughts, and pests cause substantial damage and occur quite frequently. About 40 thousand ha of stands are cut after each storm. The mean wood yield of the spruce stands is 304 m3 ha-1, and the current annual increment is 6.2 m3 ha-1. The climatic conditions of Lithuania are variable enough to cause differentiation of habitats. For Norway spruce, 6 provenance regions have been established. The national gene conservation programme is based on (a) in situ genetic reserves, seed collection stands, and selected genotypes, and (b) ex situ clonal archives, seed orchards, experimental plantations, and gene bank collections. The present-day breeding of Norway spruce comprises family tests of populations for individual and population selection, and plans for inter-population hybrids. A strategy for Norway spruce breeding has been approved for the years 2004-2013. There is a genetically diverse material for future breeding: long-distance provenance tests, and population and family tests. Assessments of two provenance tests (aged 9 and 17 years) in central Lithuania revealed superior performance of central and northeastern Polish provenances: superior height, good stem quality, and late bud-burst in spring. This may be attributed to the favourable effect of transfer: avoidance of spring frosts (late bud-burst and good stem quality), and utilisation of the later part of the growing period for growth (late bud-set and superior height). Norway spruce is a climax species with different domestic and Darwinian fitness. Therefore, we suggest that the domestic fitness of local genotypes may be improved by introducing a few Polish clones in Lithuanian breeding populations.

    Opis:
    Over 50 populations of Norway spruce from Bavaria were analysed at 23 isozyme gene loci. The mean genetic distances between these populations were quite small. A geographical grouping could not be observed, and discrimination between provenances from high and low altitudes was not identifiable using this marker type, either. The only difference between spruce populations from South Bavaria and those from Northeast Bavaria is in the presence of some distinct rare alleles. The highest values for the genetic diversity were detected for spruce stands in Northeast Bavaria (Frankonian Forest). Using STS markers, further genes of the nuclear genome of Picea abies can be dealt with. The genetic differences found on the basis of ten STS markers between different Picea abies seed lots and/or seedling populations are generally 2-3 times greater than those found by means of isozyme gene markers. DNA markers turned out to be an appropriate and substantial addition or even more a suitable alternative to isozyme markers for analysing genetic variation and testing provenance identity. Their advantages consist in a markedly wider variation as well as in the enlarged genome segments investigated.

    Opis:
    Due to the deterioration in the health condition of Norway spruce on the IPTNS-IUFRO 1964/68 observation plots in Krynica (Poland), there was an urgent need to determine the cause of the decline in order to design preventive measures. For this purpose, a health inventory was carried out in the years 2002 and 2003. This included an assessment of the condition of crowns in 144 trees and a thorough examination of 29 felled trees. It was found that individual trees or groups of trees have declined in some blocks of the experiment. The tops of some trees were dying and the crowns were getting transparent. The discolouration (turning brown) of needles was quite common and even green needles were shed. Some of the roots showed symptoms of necrosis and died. Seven taxa of pathogens were isolated from the diseased roots and trunk parts of spruces, among them Phytophthora citrophthora, Fusarium avenaceum, F. solani and Trichoderma. The number of diseased trees was related to provenance. The provenances Babenhausen (Germany), Frantiskovy Lazne (Czech Republic), Traunstein 1/4 D, 6 A, B, 7 A (Germany), Wundsiedel-Weissenstadt (Germany), Mestwinowo (Poland), and Magland (France) proved to be more susceptible than others to fungal pathogen attack.

    Opis:
    In connection with the decline of spruce stands on the Krynica plots of IPTNS-IUFRO 1964/68, observed in the last decade and attributed to the so-called spiral disease, an attempt was made to determine whether the current health condition of trees is influenced by genotype (provenance). As shown by preliminary observations, the spruces differed in the degree of survival depending on provenance. The inventories of died or broken trees to be removed during the sanitary cutting, made in the years 2000, 2003, 2004 and 2008, yielded also information about the number of spruces that remained in the blocks of the experiment for each provenance and provenance region by Krutzsch (1968). Analysis of variance showed that genotype (provenance) has a statistically significant effect on the survival of trees. In the years 1999-2008, spruces from region 21 (Bohemian Forest) displayed the poorest survival rate in the conditions of the Beskid Sądecki Mts., while those from region 80 (Eastern Siberia) survived best.

    Opis:
    This paper presents the newly suggested long-term breeding strategy for Norway spruce in Lithuania to share with the optimisation approach, which may be useful in synchronising the long-term breeding and gene conservation plans in neighbouring regions. The breeding programme in Lithuania is at a stage where the long-term plans need to be developed. Our strategy is to proceed with a closed-nucleus breeding population which is structured into subpopulations according to adaptation zones (4-5 subpopulations). The size of each subpopulation is 50 unrelated and progeny-tested individuals. The breeding cycle consists of double- pair mating and a balanced within-family selection forward. The candidates will be clone-tested. Advanced genotypes will be selected into an advanced nucleus; an isolated foreign breeding population is planned. Positive assortative mating is used for deployment. An experimental "shuttle-breeding" strategy may be tested: selection with avery high intensity, controlled crosses, nursery tests for vigour and growth rhythm, cloning by hedges into short-rotation clonal plantations.

    In the present study we analysed the mitochondrial intraspecific variation in natural populations of Norway spruce. We used the second intron of the nad1 gene, which contains two polymorphic short tandem repeats. Due to the maternal inheritance of mitochondrial DNA in Norway spruce, the spatial distribution of haplotype DNA allows insights into seed dispersal and artificial seed transfer. A total of 504 trees distributed all over Austria were genotyped, and 9 different haplotypes could be found. A geographical map of the haplotype variation pattern of Picea abies is presented.

    Opis:
    The natural stands of Norway spruce in Poland are split between the southern and the northeastern parts of the country. Two so-called "spruceless" zones separate the northern spruce locations from those in the south, one "spruceless" zone is situated in Central Poland, and the other one in the Beskid Mts. Mitochondrial (STS) and nuclear (SSR) markers were used to perform the genetic identification of Norway spruce. Four different variants of haplotypes, "a", "b", "c" and "d", were found to occur in the nad1 locus of STS markers. Populations from the northern range of Picea abies distribution in Poland harboured exclusively haplotypes "c" and "d", except for the Białowieża population which had haplotypes "a" and "c". Populations from the "spruceless" zones contained four types of haplotypes whilst those from southern Poland were mostly composed of haplotype "a". High mean gene diversity was observed for both STS and SSR markers (HT = 0.529, and HT = 0.851, respectively). The total genetic differentiation of Norway spruce populations was very low (FST= 0.088). Two main groups of populations were distinguished in the dendrogram defined by Nei's genetic distances based on microsatellite markers. The distribution of the genotypes was scattered and did not show any connection with the spatial distribution of P. abies in Poland. Only the mtDNA markers were able to differentiate the northern populations of Norway spruce from the southern ones, proving the historical separation between the Baltico-Nordic and the Hercyno-Carpathian ranges of P. abies in Poland. By contrast, the microsatellite data suggested an overlap between the genotypes due to the human manipulation of Norway spruce stands in the past.

    Opis:
    Ecochemical indexes such as soil buffer reaction (pH), acid neutralising capacity (ANCaq), alkalinity (ALK), soil acidity (Ma%), basic cation saturation (BS), and molar ratios Ca:Al and BC:Al were used to study the sustainability of Norway spruce of Istebna provenance in stands differing in age class. The data were obtained from the research conducted in the Dupniański Stream catchment in the Silesian Beskid Mts. (Poland). The acid neutralising capacity, alkalinity, and soil acidity were found to depend on the age of spruce stands. The increased acidification of deposits was due to the presence of sulphate and nitrate ions which were washed out from the surface of plants. Passing through the canopy caused a decrease in the acid neutralising capacity, alkalinity, and base cation saturation, and an increase in the soil acidity, with the values being dependent on stand age. The soil acid reaction shifted to the range of the aluminium and iron bufferness, but the Ca:Al and BC:Al ratios were still above the level when aluminium stress is probable. The washout of the basic cations beyond the spruce root system, and the low levels of exchangeable Mg2+ and Ca2+, basic cation saturation of soil water, and effective base saturation of soil may affect the vitality and health of spruce stands in the future. To maintain the sustainability of Norway spruce stands of Istebna provenance in the Dupniański Stream catchment it is necessary to increase the retention of basic elements, especially Mg2+ and Ca2+, by means of stand conversion or fertilisation.

    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 paper examines the development of the root system (both skeletal and fine roots) in 19-year-old Norway spruce (Picea abies (L.) Karst.) of two provenances (from altitudes 320 m and 1100 m), growing on two plots (540 m a.s.l., lowland, modal Cambisol; 820 m a.s.l., slope, ranker podzol), by comparing 34 parameters. The results show that the root system emergence is not affected by provenance but rather by site, namely by soil type and terrain slope. At an altitude of 540 m, both provenances produced an anchoring root system of circular floor projection with a rooting depth of 80 cm, while at an altitude of 820 m they had an elliptical superficial root system with a rooting depth of 45 cm. At the higher-situated plot, the provenance from an altitude of 1100 m showed a higher biomass, vitality, and specific length of fine roots.

    Opis:
    The work outlines the directions in the past and present research into the variability of Norway spruce in Poland, and presents the results of provenance experiments concerning the genetic and breeding value of provenances tested in the Polish range of spruce distribution. The Istebna race proved to have a good value, however, so far only the progeny of single stands have been tested. It is thus necessary to determine the range of distribution for this race. The altitude of the location of mother stands significantly correlates with the genetic and breeding value of their progeny cultivated at different altitudes. This suggests that the altitude and exposure of plantations to be established in mountain forest belts should be specified for individual provenances (altitudinal zoning). New inventory provenance tests should be run under varied site conditions to assess both the genetic value and plasticity range of the provenances. In view of the biotic and abiotic threats facing spruce, there is a need to work out detailed programmes designed to preserve its genetic resources in gene banks and in vivo archives.

    Opis:
    Trees4Future is an Integrative European Research Infrastructure project that aims to integrate, develop and improve major Forest Genetics and Forestry Research Infrastructures. It will provide the wider European forestry research community with easy and comprehensive access to currently scattered sources of information (including genetic databanks, forest modelling tools and wood technology labs) and associated expertise. This will help forestry researchers and the European forestry sector to respond, in a sustainable manner, to increasing demands for wood products and services in the context of genetic adaptation and changing climatic conditions. It will create a new and better linked Research Infrastructure that will optimize the short- and long-term exploitation of forest resources by increasing knowledge of, for example, the adaptation of forests to climate change, and the tree characteristics suitable for a tailor-made wood supply.

    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 main objective of this study was to demonstrate a relationship between the direction and effectiveness of impact of particular tree species on soil properties and the initial site fertility. The studies were conducted on two neighbouring experimental plots with different forest site types (fresh mixed coniferous forest – BMśw and fresh mixed deciduous forest – LMśw). The analysed species Norway spruce (Picea abies L. Karst.), European larch (Larix deciduas Mill.), Douglas fir (Pseudotsuga menziesii Franco) and penduculate oak (Quercus robur L.) were planted in three replications on 400 m2 plots. It was stated that: 1) the humification processes ongoing under the canopy of the analysed tree species are, to a large degree, determined by the type of forest site; 2) under the same tree species the content of calcium and nitrogen in the nitrate form was found to by markedly lower in the BMśw forest site; 3) in the BMśw forest site, the pH and electrolytic conductivity of the soil under the majority of the analysed tree species were lower; 4) the degrading impact of coniferous species on soil was noticeably stronger on the poorer BMśw forest site.
