    Opis:
    The paper provides some guidelines on the choice of the target species compositions for plantations that would replace monocultural spruce stands growing on the sites of the Silesian Beskid Mts. Part of the guidelines relates to the rules governing the sequence in which the monocultures will be converted into mixed stands. It is suggested that those rules should be combined with the principles of the establishment of progenyplantations. The seed stands of the Istebna spruce are experimentally divided into four categories according to their abilityto perform the function of a seed stand. The following features of the stands are analysed: vitality, density, stage of regeneration, protective and cultural functions. The paper contains also an outline of the methods of species conversion and the relevant references.

    Opis:
    In the experiment eight populations of Picea abies were chosen at 100 m intervals between 500 m and 1200 m altitude a.s.l.. In each population wood core samples were collected from 14–19 trees (126 cores total), and measured using a Corim Maxi device. At four of the eight sites (every 200 m in elevation between 500 m and 1100 m a.s.l.), the diversity of ground vegetation was evaluated, and temperature was recorded at every 100 m of altitude. The highest average radial increment of spruce occurred between the altitudes 800–1000 m a.s.l., which is probably the optimum for spruce. The larger increment indices observed at higher altitudes may signify a high growth potential of spruce. It may also suggest a recent upward shift of the optimum growth zone for this tree species. In 15 phytosociological records, the presence of 148 plant species forming plant associations: Dentario glandulosae- Fagetum typicum (sub-mountainous and mountainous form) and Abieti-Piceetum, and community Abies alba-Rubus hirtus, was documented. No relationship was found between ground vegetation species diversity (expressed by Shannon-Wiener index) and levels of stand diversity. The vegetation species diversity varied with the elevation above sea level: the highest plant diversity was found at 500 m a.s.l., and decreased with increasing altitude. The potential increase in air temperatures may result in changes to the altitudinal range of many plant species including trees, and consequently in an upward shift of the boundaries of plant zones; in this case the sub-mountainous and lower mountainous forest zone. In this region, the optimal zone for Norway spruce may be restricted to the highest elevations.

    Opis:
    The study presents the results of investigation on reaction of beech (Fagus sylvatica L.) leaves observed next year after planting seedlings in different positions in a young spruce stand located in upper mountain conditions. The methods of chemical analyses and assessments of chlorophyll fluorescence were applied with the aim to evaluate a course of leaf adaptation. In the young spruce stand located in the Karkonoše Mts, bare root beech seedlings after cultivation in full light were planted into three main positions to spruce trees (under the crown, within crown perimeter and in stand gaps). Next year after planting, the total biomass, leaf nutrient content and chlorophyll fluorescence parameters were evaluated. The beech trees planted under spruce (Picea sp.) crowns had significantly lower specific leaf mass and the mean leaf area was decreasing from shade to sun. Differences in nutrient contents were not significant between the treatments. We found significantly higher values of minimal (F0) and the maximum fluorescence (Fm) as well as of the maximum quantum yield of PSII photochemistry (Fv/Fm) in the leaves of beeches growing under the spruce crown. Significant differences among treatments were found also in the courses of the values of maximum fluorescence yield Y(II) and nonphotochemical quenching (NPQ). Our study indicated that bud forming processes are only partially responsible for physiological properties of beech leaves evaluated next year after planting. Photosynthetic performance is also influenced by actual growing conditions. A great part of acclimation occurs already in the first year after planting (change of the light conditions). We speculate that this phase of gradual acclimation of the assimilation apparatus can be one of the reasons of physiological weakening of the plant after planting to different light environment.

    Opis:
    The health condition of spruce stands in the Moravian-Silesian Beskids is affected by several predisposition factors, the most important of which is the allochthonous character of spruce grown on improper sites. When exposed to a low supply of nutrients and intensive mechanical damage mainly by game, the trees are susceptible to rot infestations, climatic agents and mechanical destruction by snow, hard rime and wind. At present, air pollution does not show any significant impact on the spruce stands; it rather acts as a less important predisposition factor on mountain peaks. The physiological condition of trees is not impaired to the extent which would facilitate infestation with phytophagous or cambioxylophagous insects.

    Opis:
    The objective of the research was to analyse the level of fungal infection of spruce wood in the mature and overmature stands and determine the age of their technical maturity. Trees from seven stands aged 49−137 were examined. Age was found to have a statistically significant effect on the level of infection of trees caused by wood−rotting fungi. A high infection level was also detected in the bark−stripped spruces of the lower storeys of multi−storeyed stands. The obtained results enabled determination of the age at which spruces are considered mature (technical maturity) for felling at 80−90 years.

    Opis:
    Actual status of mountain forests especialy, of Norway spruce (Picea abies Karst. (L)) stands is a result of combined action between forest management measures and biotic and abiotic risk factors. In this context, tree growth dynamics is a result of multifactor interaction (competition, disturbance, management practice, climate etc.). Wind damage affect the stand structure and normal ecosystem functions including the relationship between individual tree growth and competition processes. Though, it is recorded a diminishing of productive capacity for affected stands as well as a significant diameter increment for remaining standing trees. The correlation between tree growth (cumulate basal area increment in the last 10 years) and competition (Hegyi and Schutz competition indices) was analysed in stands with different windfall intensity. No relationship between tree growth and competition was observed in highly affected stands. Schutz competition index explains better individual tree growth comparing with Hegyi index in low or no-affected stand by windthrow. The variability of the basal area increment (lnΔɡ10), explained by competition indices, is rather low (<2%) in the stand that had been highly affected by windfall, regardless of the selected competition index. Thus, significant reduction of the stand density related to number of trees (low density), as a consequence of high intensity windfalls, crown competition has a very small influence on the basal area increment comparing with situations met in low (high density) and moderate (medium density) affected stands.

    Opis:
    The incidence and severity of butt rot were assessed in 12 selected Norway spruce seed stands in the Beskidy Mountains, Poland. A semi-invasive technique of sonic tomography was used for the assessment of rot damage. Stands of different age classes (100–120, 130–150, 160–170 years old) and distinct regions of provenance (Istebna and Orawa) were investigated. Hierarchical analysis of variance was used to determine effects of stand age and stand provenance on butt rot occurrence at a stand level. High incidence of butt rot was noted in all of the studied seed stands (47% to 87% of diagnosed tree samples). Stand age had a significant effect on percentage share of ‘damaged wood’ on the tomogram. The extent of rot damage was rising with stand age, and the largest was observed in the age category 160–170 years. Spruce stands of Istebna provenance were generally more damaged by butt rot than those of Orawa provenance, however, the latter have been growing in forest sites more suitable for spruce in terms of fertility and altitude. Hierarchical analysis of variance did not show a statistically significant relationship between the region of provenance and average share of ‘damaged wood’ on the tomogram. Presented results indicate that for stands growing in similar conditions vulnerability to butt rot is determined by stand age. Further research is needed to separate impact of stand provenance identified with specific genetic constitution of a population from the effect of environmental conditions typical of a given region of provenance.

    The aim of the study was evaluation of knots in wood of 150-year-old Norway spruce [Picea abies (L.) Karst.] in stands situated at the altitude of 1450– 1740 m above sea level in the Dolomites in Italian section of the Alps. In selected stands, spruce trees were cut down and their length, stem thickness, height to the crown base and stem diameters at every 1 m along the length of merchantable bole were measured. The diameter of knots was measured and they were classified according to their healthiness and the degree of their tightness with the surrounding wood. The relative knot diameters were calculated and the relative height of their location on stem was determined. In total on sample trees there were analysed 1070 knots, of which sound knots (close to 75%) and tight (more than 60%) prevailed. Sound and tight knots had largest diameters, relative diameters and relative heights of location on merchantable boles. The smallest diameters and relative diameters were indicated by rotten and not tight knots that were located at the lowest merchantable bole parts.

    Opis:
    Ectomycorrhizal communities structure of Norway spruce (Picea abies L. (Karst.) was studied in four mature forest stands: Brenna, Salmopol, Zwierzyniec and Mirachowo. Morphological classification was used to distinguish the major mycorrhizal types associated with spruce in different forest types. Three of the foreststands were located within the natural geographical range of Norway spruce (Brenna, Salmopol, Zwierzyniec) and one (Mirachowo) was located in so-called “spruce-less zone”. The sites differed in terms of environmental pollution. The mountain sites (Brenna, Salmopol) were characterized by relatively high levels of air pollution. The upland forest stand (Zwierzyniec), located in the southeastern part of Poland, was affected by a moderate pollution. The lowland stand in northern Poland (Mirachowo) was free from direct impact of anthropogenic pollution. The level of mycorrhizal colonization was 100% at all the study sites. Thirty-seven mycorrhizal morphotypes were distinguished in total. The number of ectomycorrhizal morphotypes varied between sites from 12 in Salmopol to 28 in Zwierzyniec. From one to three dominant morphotypes were found at the study site. Site-specific morhotypes were also observed. The frequency of mycorrhizal morphotypes differed between the forest stands.

    The study deals with long-term dynamics of snags and fallen dead wood from 1970 to 2010 in an unmanaged forest ecosystem dominated by European beech in the Bažinky area, Krkonoše National Park (Czech Republic). The volume of dead wood was estimated from 1970 separately for fallen dead wood (logs) and standing dead wood (snags and stumps). Total dead wood volume on permanent research plot (PRP) 6 increased from 41.9 to 241.6 m3 ha–1 and on PRP 7 from 27.7 to 170.0 m3 ha–1. During 40 year case study the mean total volume of fallen dead wood was 193.3 m3 ha–1 (± 29.8 S.E.) and 96.2 m3 ha–1 (± 19.4 S.E.) and the mean total volume of standing dead wood was 17.4 m3 ha–1 (± 3.4 S.E.) and 12.6 m3 ha–1(± 1.4 S.E.) on PRP 6 and PRP 7, respectively. Comparing tree species, the mean volume of fallen dead wood was significantly higher for Norway spruce than for beech in the decomposition class 1 (F(1, 14) = 5.7, P = 0.03) and significantly higher for beech in the decomposition classes 4 (F(1, 14) = 20.4, P < 0.001) and 5 (F(1, 14) = 25.5, P < 0.001). Dead wood was distributed from randomly to aggregated spatial pattern. Despite the rapid decay of beech wood, the amounts of deadwood are likely to increase further during the next decades with continuing disintegration of the forest stand.

    Opis:
    The study analyses the transfer of F-, Cl-, NO3-, SO42-, Na+, K+, Ca2+, Mg2+, Fe2+, Mn2+ and Zn2+ from bulkprecipitation to throughfall, soil surface flow, vertical flow and intercover flow of water (gravity lysimeters at 20 cm soil depth) in spruce stands of different age classes (1st, 2nd, 5th, 6th), and the amount of these ions flowing out from the Potok Dupniański catchment in the Silesian Beskid Mts. The results cover the year 2000. The concentration and amount of SO4 2- in throughfall systematically increased and the pH value decreased with the age of the stands and with successive elements of the ecosystem. The NH4+ ion was probably absorbed in the canopy, which caused a washout of K+, Mn2+, F- and SO42- in the vegetation season in older stands. In the winter season, Fe2+, Mn2+, Na+ and K+ were washed out from the youngest stands (1st age class), whereas F-, NO3 -, SO42--, K+, Ca2+, Mg2+, Mn2+ and Fe2+ – from older canopies. Decomposition of the organic matter caused a rise in water acidity and an increase in the concentrations of all the analysed ions; their leaching, however, was low (under 1%). Water from intercover flow contributed to an increase in the amount of water and the concentration and amount of ions and to a further decrease in water reaction at a soil depth of 20 cm. All the anions and cations flowed away with water penetrating vertically and horizontally. Considerable amounts of ions, especially SO42-, Na+, K+, Ca2+ and Mg2+, were carried beyond the reach of the main mass of the root system and then out of the catchment, which may adversely affect the development and health of spruce stands.

    Opis:
    The experimental plots were located in the middle forest zone (900– 950 m) on two nappes of the flysch Carpathians: Magura (the Ujsoły Forest District) and Silesian (the Wisła Forest District) in the spruce stands of age class 21– 40 years. Serpentinite was introduced in the autumn of 2008 on all plots while other fertilizers (N, P, NP and NPK) in the spring of 2009. Based on the chemical composition of soil solutions collected in lysimeters placed at the depth of 20 cm in the autumn 2008 and the spring and autumn 2009, ecochemical parameters were calculated: acid neutralization capacity (ANCaq), alkalinity (ALK), the degree of soil acidity (Ma%), acidic cations (Ma), saturation of the exchangeable complex of the soil solid phase (Mb) with alkalis, saturation with alkalis (BS), molar relations Ca/Al, Mb/Al, BC/Al. After the winter, soil solutions became acidic, especially in the Wisła Forest District. The saturation of the studied soils demonstrates moderate flexibility of soils in the Wisła Forest District in relation to acid load, and high flexibility of the Ujsoły soils. The opposite trend was observed for the degree of acidity of soils. Acid neutralization capacity and alkalinity of the waters showed significant variations in soil pH even in the case of small variations in the composition of the solution, if they were caused by the inflow of the anions of NO3 - and SO4 2-. After application of the fertilizers, an increase of Mg, Ca and Mb was noted in the soil solution, determined in the overlaying highly acidic organic horizons trough the ion-exchange buffering mechanism of highly protonated functional groups with high buffering capacity. Highly improved content of Mg in a soil, and in some cases – also the content of N, P and K, present potential improvement of forest growth capacity without the hazard of adverse side-effects of liming. Aluminum stress in the spruce is unlikely, while trees in the control plots in the Wisła Forest District may already be sensitive.

    Opis:
    The effects of drought stress, stress by increased nitrogen depositions and the combined effect of the two stress factors on the growth of Norway spruce Picea abies (L.) Karst. were studied in two stands. The drought stress was induced by reducing atmospheric precipitations by 60% and the increased nitrogen depositions were simulated by repeated applications of ammonium sulphate at a rate corresponding to 100 kg N ha–1 year–1. All stress factors under study affected the height increment of the above-ground part, the length and colour of needles, and the biomass, vertical distribution, functionality and mycorrhizal infection of fine roots. The root system responded to the simulated stresses right from the the very first year of their action, exhibiting a greater damage than the above-ground part of the plant. Drought acted as a stress factor stronger than the nitrogen depositions themselves. The strongest impact was recorded in the simultaneous influence of the stress factors.

    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.

    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:
    This paper addresses the question of whether or not and to which extent two common tree species mixtures (Norway spruce – European beech; sessile and pedunculate oak – European beech) vary in volume growth from their monocultures. To this end, the results from selected long−term experimental plots located in Germany, Poland and Switzerland, with many of them under survey since the 1890's, were employed. We found than on average both type of mixtures exceeded volume growth in pure stands by almost 30%. The analysis at the species level showed than only a Norway spruce response to mixture was neutral on average, while other tree species were benefitted by mixture. An empirical derived model for mixed stand of oak and European beech disclosed that the interaction can range from facilitation and overyielding on poor sites, through the neutral response under mesotrophic conditions, up to underyielding on fertile sites triggered by competition.

    Opis:
    The objective of this research was to describe the horizontal distribution of trees in the managed Norway spruce stands located in the Sławno Forest District. The knowledge of that stand feature may be useful for the forest management in natural as well as in artificial stands. This paper presents the analysis of the spatial pattern of trees belonging to the different diameter classes in two separate stands. Majority of the living trees in both stands characterised with random spatial distribution. Trees with small (≤20 cm) dbh were localised in groups the most often.

    Opis:
    Stand characteristics were analysed for the occurrence of regrowth with a species matching the dominant species of a stand. The analysis covered: stand age, stocking, degree of shelter (the sum of stocking plus the percentage of the shrub layer cover), dbh basal area, type and the dominant species of the vegetation cover. The obtained results were considered as preliminary criteria of the maturity age for regeneration.

    Opis:
    The paper presents temporal relationships between the breakdown of tree stand in the subalpine spruce forest and the regeneration of rowan (Sorbus aucuparia L) as well as the rate of height growth of rowan stems. Rowans growing in a large gap recruited mostly from the seedling and sapling bank established under the living spruce stand before its breakdown. The rate of stem height growth was five times higher after the gap formation than under spruce stand. In spite of considerable age differences of rowans the variability in their final height after over 20 years of rapid growth was small.

    Opis:
    The purpose of the strictly protected area of the Białowieża National Park (BNP) established in early 1900s, was to protect a compact block of the Białowieża forest from any direct human influence and activity. Its founders considered it a “laboratory of nature.” In 1936, five rectangular plots with a total area of ca. 15.5 ha (ca. 0.3% of the BNP) were set up for regular monitoring of stand development with regards to the initial state and variability of soil conditions. During the first 76 years of the project, a steady increase in the proportion of hornbeam and lime tree at the expense of shade-intolerant species was observed. This trend has been interpreted by the researchers involved in the monitoring of the permanent BNP plots to constitute a biodiversity-threatening development caused by preservation efforts. Such an interpretation has been widely incorporated in the public debate by political authorities and the forestry sector. In this critical article I challenge the major arguments presented by the key expert in silviculture, prof. B. Brzeziecki. My criticism is directed at the methodological approach as well as at the data interpretation.

    Opis:
    Major results of the 45−year−long study on the dynamics of strictly protected forest stands, using 3 permanent study plots, 25×100 m each, located on a former narrow strip clear cut established in the beginning of the 20th century on the northern slopes of the Mt. Łysica (the Świętokrzyskie Mountains, Central Poland) are presented. The general development of forest stands is analysed, including change of overall density, tree mortality rate (general and by species), dynamics of basal area and average tree diameter, competitive ability as well as changing role of particular species (mainly European beech, silver fir, sycamore and Norway spruce) in formation of the general stand structure. The results of the study are compared with other investigations of similar type.
