    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 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.

    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:
    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 concentrations of Cu, Mn, Ni and Zn in the soil and litterfall, as well as influx of the elements to the soils with litterfall were studied in a mixed beech-pine-spruce stand in northern Poland during the years 2007–2009. Annual influx of litterfall to the soil amounted from 3.234 to 4.871 t/ha. Beech, pine and spruce litterfall contributed in total litterfall in 50.8−70.1%, 11.4−11.9% and 1.6−24.0% respectively. The following average annual concentrations of heavy metals in total litterfall during the 3-year study period were noticed: 2469.3–3469.2 mg Mn/kg, 153.6–160.8 mg/kg Zn, 8.0–14.3 mg Ni/kg and 5.0–6.8 mg Cu/kg. In general, the concentrations of Mn and Cu were higher in beech litterfall in comparison to pine and spruce. The contents of Zn and Ni in beech, pine and spruce litterfall were comparable. Annual influx of metals to the soil with litterfall was: 10341.6–14422.4 g/ha Mn, 460.3–748.1 g/ha Zn, 37.4–66.6 g/ha Ni and 20.2–31.8 g/ha Cu. The fluxes were higher for Mn, Zn and Ni, and comparable for Cu in relation to those observed in other beech, pine, spruce and mixed stands in northern Europe.
    W latach 2007–2009, w drzewostanie bukowo-sosnowo-świerkowym zlokalizowanym na obszarze Polski Północnej, prowadzono badania zawartości Cu, Mn, Ni i Zn w glebie i opadzie roślinnym oraz dopływu tych składników do gleby z opadem. Roczna produkcja opadu roślinnego w okresie badań wynosiła od 3.234 do 4.871 t/ha. W całkowitej jego masie udział opadu buka wynosił 50.8−70.1%, sosny 11.4−11.9%, a świerka 1.6−24.0%. Średnie ważone roczne stężenia badanych metali w opadzie roślinnym mieściły się w przedziale: 2469.3–3469.2 mg Mn/kg, 153.6–160.8 mg Zn/kg, 8.0–14.3 mg Ni/kg i 5.0–6.8 mg Cu/kg. Na ogół wyższe stężenia Mn i Cu obserwowano w opadzie buka w porównaniu z opadem sosny i świerka, a zawartość Zn i Ni była porównywalna. Roczny dopływ metali do gleby z opadem roślinnym wynosił: 10341.6–14422.4 g Mn/ha, 460.3–748.1 g Zn/ha, 37.4–66.6 g Ni/ha i 20.2–31.8 g Cu/ha. Na tle danych uzyskanych przez innych autorów w drzewostanach bukowych, sosnowych, świerkowych i mieszanych występujących w Europie Północnej, odnotowany w badanym drzewostanie dopływ Mn, Zn i Ni był większy, a Cu porównywalny.

    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:
    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 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.

    The radiation exchange drives the plant ecosystems energy balance and provides the energy for photosynthesis, transpiration and plant growth. The investigation on net radiation and its component during vegetation season in relation to the clearness index and sun elevation in a cultivated 31-year-old mountain spruce [Picea abies (L.) Karst.] stand is presented. Downward short-wave radiation – Sd (incident on the spruce stand was the main part of the short-wave radiation balance during the whole growing season (April–October) 2008. The Sd a mount i s seasonally variable factor determined by the duration of solar shine and the atmosphere transmissivity. Obtained value of net radiation (Rn) and downward short-wave radiation (Sd) ratio amounts to 0.61 on average during the growing season 2008 documenting the importance of the downward short-wave radiation in the net radiation of investigated spruce stand.

    The paper presents nearly 30−year changes in the structure of a 160 ha subalpine spruce stand in the Tatra National Park that has been subjected to strict protection during last 50 years. In 1973 a regular network of 65 small 0.05 ha circular plots was established over the whole area. In 2002 diameter and height of trees were remeasured in 61 plots. Similar changes were recorded nearly in the whole forest area. The density of trees decreased and the stand volume increased considerably on most plots. At the same time the variability among plots in trees' number and volume decreased and in 2002 the stand became more homogenous in terms of both characteristics. The obtained results were compared to the suggestion of Korpeľ that subalpine spruce stands reach the equilibrium between decay and growth processes on the area of 70 ha. The investigated forest was far from such equilibrium in spite of its area being more than two times bigger than that suggested by Korpeľ.

    Opis:
    The study on the structure of Norway spruce old−growth stands of original provenience in upper mountain zone was carried out in a nature reserve ‘Śnieżnik Kłodzki', located in the Lądek Zdrój Forest District (SW Poland). The fieldwork was conducted in three spruce stands located at the altitude of 1,215 and 1,235 m a.s.l. The breast height diameters (dbh) of living trees were characterized. The aim of this study is to characterize the structure of dbh of trees in spruce stands of subalpine forest. Implementation of the objective will be associated with the characteristics of empirical distributions dbh and an indication of theoretical distributions of continuous random variable best approximating the structure of dbh. The comparison of empirical dbh distributions with 36 theoretical distributions were carried out, but goodness−of−fit tests proven statistically significant compatibility with seventeen of them: beta (4−parameter), Cauchy, exponential power, folded normal, gamma (3−parameter), generalized logistic, Laplace, logistic, loglogistic, loglogistic (3−parameter), lognormal (3−parameter), noncentral chi−square, normal, smallest extreme value, triangular, Weibull and Weibull (3−parameter). The dbh distributions in upper mountain spruce stands are the best fitted with logistic distribution, and subsequently loglogistic (3−parameter), generalized logistic and Weibull (3−parameter) distributions. That four distributions can be used in individual tree growth models while generating structure dbh of trees in the stand. The knowledge of dbh structure in protected stands could be helpful in shaping spruce stand structure in planned silvicultural treatments, and shows the need for silvicultural treatments in upper mountain spruce stands.

    Opis:
    The aim of the study has been to assess the influence of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies) admixture in European beech (Fagus sylvatica) stand on some properties of organic and humic horizons of Dystric Arenosols and the intensity of biological turnover. The studies were conducted in northern Poland in Łysomice Forest Subdistrict (Forest District Leśny Dwór, Regional Directorate of State Forest Szczecinek). Significant differences in some properties of examined soil horizons were noticed between the stands. About 3-times higher stocks of organic matter in ectohumus were found in beech-pine and about 2-times in beech-spruce in relation to pure beech stand. Higher stocks of soil organic matter recorded in beech-pine and beech-spruce stands may result from the influx of coniferous litter and reduction of the intensity of biological turnover. The stocks of organic matter in A horizons were slightly higher in beech stand. Lower values of pH in O and A horizons were found in mixed stand in relation to pure beech. The concentration of nitrogen was comparable in both stands. It can be assumed that spatial variability of the stocks of nitrogen was strongly related to spatial diversity of soil organic matter stocks.

    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.

    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 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:
    A study was carried out to compare the annual ring width, latewood share and density of spruce wood from the north eastern a nd south w estern ranges of Norway spruce. Twelve trial plots were located in the north eastern range, while within the south w estern range eight trial plots were established in the Sudeten Mountains and twelve trial plots in the Carpathian Mountains. On ev ery trial plot fifteen spruce trees were chosen, from which increment cores were sampled using a Pressler borer. Next, the increment cores had their surfaces smoothed and measurements were made of the width of annual rings, latewood zones and the share of latewood. Then the cores were divided into 2 cm sections, for which the relative wood density was determined. The analyses indicate that annual rings were wider in trees growing within the north eastern range than in those from the south western range an d the Kruskal Wallis test showed the differences to be statistically significant. T he latewood share followed an opposite pattern: t he wood from the Mazury region had a higher proportion of latewood than the wood from the mountainous areas and the statist ical test again indicated that the differences were significant. The analys i s of wood density showed slight differences between the density of wood from the north eastern and south western ranges, but in this case the Kruskal Wallis test showed the differe nces to be statistically insignificant.

    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:
    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 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:
    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 aim of the study was to determine the influence of stand density index on the tree−ring width, latewood proportion and wood density for Norway spruce. Study sites were located as follows: 12 within the north−eastern species range in Poland, 7 in the south−western range, in the Sudety Mts., and 9 in the Carpathians (southern range). Clustering stands according to their stand density index, 10 data groups were established: stand density index values from 0.3 to 1.2. The study plots were 100×100 m squares. On each plot 15 trees were chosen and increment cores were sampled using the Pressler borer. The smoothed cores served for measuring the width of annual rings, latewood zones and the share of latewood as well as for determination of relative wood density. The performed analyses indicate that mean tree−ring width was the highest in trees from stands with density index from 0.3 to 0.8 (with the exception of 0.7), whereas the it was gradually decreasing in stands with index higher than 0.9. The statistically significant differences between the analyzed stands were observed (p<0.0001). The analysis of the influence of stand density index and the width of annual rings revealed significant, negative weak correlation (r=–0.242, p<0.001). In turn, the latewood proportion was the highest in trees from stands characterised by the highest stand density index and the lowest in trees from stands with the lowest one. The differences between analyzed groups of stands were statistically significant (p<0.0001), as well as the correlation which was significant, positive and weak (r=0.269, p<0.001). Wood density was the highest in trees from stands with the highest stand density index (1.1 – 363 kg/m3 i 1.2 – 365 kg/m3) as well as in those from stands characterised by 0.7 density index (369 kg/m3). Significant differences were observed (p<0.0001) only between stand density index 0.3−0.7 and 0.7−0.8. Significant correlation was not observed.

    The forests of the Silesian Beskid Mts have a specific composition with a marked dominance of Norway spruce. Although spruce stands are seriously threatened, some of them, such as those of Istebna race, show excellent genetic value. The work stresses the need for the conversion of spruce stands in the Silesian Beskid range on the basis of population genetics and describes the principles of such conversion.

    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.

    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.

    The aim of the present research conducted in the Beskid Śląski was to search for an appropriate, alternative to classic way to regenerate the forest at high mountain altitudes. An attempt was made, therefore, at regeneration of these areas using the group method that imitates the natural formation of spruce biogroups in the forest. It was concluded that the choice of place for planting should entail the time of snow cover disappearance as well as the differentiation of microsites, kind of protection and plant cover. The assessment performed favours the biogroup method of setting up spruce cultures in higher mountain altitudes, especially in areas close to the mountain top.

    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.

    The objective of this study was to determine the influence of the age of parent tree stand on selected physical properties of Norway spruce seeds to improve the efficiency of seed separation processes. Seeds were harvested in a forest complex located in the seed zone No. 202, in the municipality of Kruklanki in the Borki Forest District (N Poland) during mast years (1999, 2004, 2007 and 2012). The experimental material comprised of Norway spruce seeds from three differently aged tree stands (86, 119 and 129 years old in the first harvest year). The following measurements were performed for each seed: terminal velocity – with a pneumatic classifier; length and width – with a laboratory microscope; thickness – with a thickness gauge; angle of external friction – on an inclined plane, in two positions on a steel friction plate, and mass – with a laboratory scale. The results were used to calculate the arithmetic and geometric mean diameters, aspect ratio, sphericity index and density of seeds. The values of the analyzed properties were compared with ANOVA for factorial designs and linear correlation analysis. The results of the study indicate that Norway spruce seeds obtained from cones harvested in 2012 are characterized by the highest thickness and, consequently, by the highest values of the aspect ratio and sphericity index. The age of parent trees significantly influences the majority of physical properties of seeds. However, the patterns of observed changes are difficult to interpret due to the impact of weather conditions and the genetic potential of parent trees, which perform differently in response to changing climate and geomorphological conditions. Over the analyzed 13−year period a gradual increase was noted in the width, geometric mean diameter, aspect ratio and sphericity index of seeds, whereas the length and density of seeds decreased. Therefore, Norway spruce seeds should be separated mostly with the use of mesh screens with longitudinal openings, pneumatic separators and graders. The use of those devices, separately or in combination, for sorting Norway spruce seeds into mass fractions could contribute to more uniform seedling emergence when every seed fraction is sown separately.

    The research focused on the effect of environmental factors on the stability of mountain spruce forests in the Beskidy Zachodnie. Stand stability was evaluated on the basis of slenderness, relative crown length and intensity of volume increment. The performed analyses show that stands growing at higher elevations are more stable. This is related, among other things, to worse environmental conditions resulting in the lower slenderness value and higher relative crown length.

    Opis:
    The aim of this study was to characterise the aboveground litterfall in a 110−year−old beech stand with admixture of pine and spruce based on a 3−year measurement series. The studies were conducted in 2007−2009 in the Leśny Dwór Forest District (NW Poland). The input of litterfall during the study period amounted from 3.234 to 4.871 t/ha/year. Beech, pine and spruce contributed in the total litterfall mass in 50.8−70.1%, 11.4−11.9% and 1.6−24.0% respectively. Beech leaves were the main component of litterfall, accounting for 39.6−52.4%. In the masting year for beech (2009), seed coats and beech seeds had also a significant share in the mass of litterfall. The bark beetle outbreak, which occurred during the study period, influenced the dynamics and properties of spruce needle fall. In the outbreak year (2008), a several fold increase in the mass of needle fall, mainly green needles, from spruce trees was observed. The beech leaf fall compared with other components of the stand was rich in phosphorus, potassium and calcium, and moderately rich in nitrogen, had the lowest C:N and C:P ratios and the highest pH value. The needle fall of pine and spruce was much less rich in nutrients and strongly acidic. It also showed a broad range of C:N and C:P values.

    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:
    One of the most important objective of the active nature protection in national parks situated in Polish mountains is the restoration of mixed stands replaced by Norway spruce monocultures. Seven spruce stands situated in the Tatra National Park were measured in 1983−1986 and in 2001. The density of all stands decreased whereas the basal area and volume increased. In some of them the changes were considerable. The contribution of Fagus sylvatica and Abies alba, two most important tree species in natural mountain forests, changed only slightly and even decreased in three stands. Intensity of elimination of trees was related to their thickness – thin trees were removed from stands more often. Due to this way of thinning the variation of tree thickness diminished in all spruce stands. The densities of Fagus sylvatica and Acer pseudoplatanus saplings increased in all stands as a result of former planting. However, they are still to low for effective restoration of mixed stands. It can be concluded that mainly sanitary cuttings have been used recently in all stands. This line of management is not deliberately focused on the restoration of mixed stands and the diversification of their structure. It results in aging of dense spruce stands and increases the risk of future large−area disturbances due to strong winds and insect outbreaks.

    Opis:
    The study aimed at analyzing the oak population structure was performed on the 29−hectare plot representing stands dominated by spruce in the strict reserve of the Białowieża National Park. It revealed that oaks represent two distinct cohorts: the old, emerged in the late 1800s, and the new that is being established in the area subject to mass decline of spruce. We suggest that the first regeneration wave was the result of ceasing the frequent ground fire regime that prevented the regeneration of trees except for pine. The current wave has been prompted by a set of changes in the habitat quality, following the breakdown of dense spruce−dominated stands. These changes, such as access to sunlight, accelerated decomposition of spruce litter, local exposure of mineral soil, and protective structures of lying spruce logs, provide regeneration advantage to oak and other intolerant species.

    Opis:
    The dynamics of decline of Norway spruce forests in the Beskid Śląski Mts. (S Poland) in a 2007−2016 period was analysed based on data from the State Forests Information System. For that purpose we used modified growth model and wind damage risk model. The harvested timber volume (salvage cuts) exceeded the allowable harvest modeled with the stand growth model by 270% in years 2007−2010 (earlier period) and by 89% in the 2011−2016 (later period) period. The highest volume exceed (503 and 307% for earlier and later period respectively) was recorded for the Wisła Forest District. For the deadwood, the harvested volume exceeded the modeled one by 45% (162 in earlier, and 59% in later period). In the Węgierska Górka Forest District the harvested volume amounted to 287% of the modeled one (438 in earlier, and 70% in later period). The largest amount of wind−broken and wind−fallen trees was found in Wisła. Their volume amounted to 48% of the modeled volume (59 in earlier, and 40% in later period). The highest exceed occurred in Węgierska Górka (89 and 70% in the later period respectively). The species composition in the analysed region changed significantly as the share of spruce decreased and share of beech and fir increased (tab. 1). Changes in the aeral fraction of stands in age classes in the Bielsko and Ustroń forest districts were insignificant (tab. 2). For Węgierska Górka, share of stands in age class <20 years increased from 11 to 40%, while the older stands fraction decreased. Major changes occurred in Węgierska Górka and Wisła as far as structure of the stands in the risk damage factor classes is concerned. Fraction for the risk factor classes I and II increased, while for class VI decreased (tab. 3, fig. 4). The highest dynamics of the wind threat measure was recorded especially in Węgierska Górka, where its value decreased from 42 in 2009 to 19 in 2016 (fig. 5). The biggest changes are likely to occur in Wisła in the next years due to the very high fraction of spruce. A significant damage caused by wind may also be expected in Ustroń, where the threat measure is high.

    Opis:
    The paper presents the effect of artificial regeneration of stands with pine on a clear−cut area on the species composition of Calamagrostio−Piceetum association of reed−bed – spruce mixed coniferous stands frequently occurring in the Wigry National Park. The studies were carried out in two groups of pine stands: the old−growth stand at the age of 130−150 years, possibly established by way of natural regeneration and young−growth stands established by planting pine on clear−cut areas. Using traditional methods of phytosociological analysis no significant qualitative differences were found between the herbaceous vegetation of the both stands.

    Opis:
    One of the tree species appearing after a decline of Norway spruce Picea abies (L.) H. Karst. in the Silesian Beskid Mountains is Silver Birch Betula pendula Roth. Therefore our study was aimed at evaluating this birch regeneration and the dynamics of changes resulting from experimental cutting. Measurements and inventories of trees were conducted on research plots located in a ten-year old birch regeneration site with either no cutting, partial cutting (50%) or clear cutting (100%) of birch. We observed an introduction of biocenotic species (rowan, willow, aspen) as well as the target species (spruce, fir, beech) under the birch canopy. Fir and beech were also planted, because of their slow natural regeneration. The clear cut treatment caused a great number of sprouts growing from birch stumps, reaching a height of about 2 m over 3 years, resulting in competition with the regeneration of other species. Partial cutting did not cause such a drastic amount of sprouting. Furthermore, we found that only the spruce height increment is significantly less under a birch canopy compared to open space. The obtained results indicate a necessity to adjust the density and species composition of regenerating tree species under a birch canopy, avoiding complete removal of the first generation birch cover and the need to moderately thin out birch.

    Opis:
    In the natural stands of the lower−montane zone in the 'Łopuszna Valley' Reserve (Gorczański National Park) consisting of beech, fir and spruce, a specific phenomenon was observed, which in other natural forests of the Western Carpathians occurred only occasionally. In the years 1981−2011, along with the increase in the proportion of beech in stands and in regeneration, which is now common issue in the forests of Central Europe, an increase or stability in the proportion of fir in stands and an increase in the proportion of fir in the undergrowth was reported. At the same time, the number of spruces in stands clearly decreased, while in the regeneration they occurred sporadically. Reduction in the proportion of spruce leads to a change in the species composition of multi−species stands i.e. from stands with co−dominant beech, fir and spruce to stands with dominant beech or co−dominant beech and fir. In managed forests, it is necessary to maintain the prevalence of all tree species for their productivity, which requires the application of the best silvicultural practices (regeneration and tending).

    Opis:
    The aim of this research was to find out what changes occurred between 1999-2009 in Oszast reserve in the volume, species composition and diameter at breast height (dbh) distribution of the forest stand, and the number and height of regeneration. The objective was to determine what would be condition of these managed lower montane multispecies forest stands (Swiss irregular shelterwood method or selection cuttings) and what role spruce would play in them if they have not been replaced by spruce monocultures. The research was conducted on three permanent circular sample plots (s.p.), each had size of 1/3 ha. Over 10 years, standing volume of the forest stand increased on s.p. 1 (from around 562 m3 ha-1 to 649 m3 ha-1) and s.p. 3. (from 653 m3 ha-1 to 660 m3 ha-1), while decreased on s.p. 2. (from 421 m3 ha-1 to 378 m3 ha-1). The species composition, defined on the basis of volume share (averaged for the three s.p. jointly), did not undergo consistent changes. However, the relative dominance of beech over spruce was determined based on tree numbers. The average spruce mortality (averaged from three s.p.) did not exceed 10% and was slightly higher than that of beech (6%), and lower than fir mortality (15%). Nevertheless, spruce did not show any symptoms of dieback. The reasons behind its mortality were fallen trees and windbreaks. In regeneration, on the whole, beech or sycamore predominated, and the proportion of spruce and fir was small. In the future spruce and fir may even decrease further by competitive ability of dynamically regenerating beech. Abandonment of forest management to promote greater diversity of species, may favour the formation of beech monocultures, or forest stands dominated by beech, everywhere that beech is already present or will be introduced. The maintenance of stable, multispecies forest stands, with co-dominant fir, beech and spruce of native origin, requires natural or artificial regeneration of spruce and fir, manipulated to restore fir up to about 30%, and reduce spruce down to about 40%. This would be possible through the use of the Swiss irregular shelterwood method and selection system, and by continuous tending of regeneration.

    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.

    Opis:
    The study was conducted in the Polish (Roztoczanski National Park) and Ukrainian (Rava-Rus'ka Landscape Reserve and Yavorivskyi National Park) parts of the Roztocze region. In each of these locations three research areas were established in Scots pine (Pinus sylvestris L.) stands under similar ecological conditions. The purpose of this study was to carry out a survey of possible scenarios for pine stand dynamics in the Polish and Ukrainian parts of Roztocze using the FORKOME model. A control scenario was compared with four other climate change scenarios (warm dry and warm humid; cold dry and cold humid) for a period of covering the next 100 years. Using the control scenario, the FORKOME model predicted that for the next 100 years pine stands will dominate in terms of biomass and number of trees. The warm-dry and warm-humid climate scenarios resulted in slightly reduced biomass of pine stands. However pine would still maintain its dominance, although with a noticeable increase in beech and fir biomass. Nevertheless, in term of the number of trees during the second half of the simulation, it is beech and fir that dominate stand 1 in Roztoczanski National Park. Under the climate cooling scenario (cold dry and cold humid), the biomass of pine and spruce would increase during the next 100 years. Pine trees that would dominate in terms of their numbers, although the number of spruce individuals also tends to increase. The results presented in the paper indicate that the FORKOME model is very useful when investigating different climate changes scenarios in the Roztocze region.
