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 study was to investigate variability of chemical features of upper horizons in forest soils as well as confirmation of collecting the mixed sample that is supposed to describe the soil conditions more effectively. The lowest variability (ca 10%) was observed for pH in H2O and KCl as well as C/N ratio. The highest coefficient of variance exceeded 100% (Ca content). For almost all analysed chemical parameters, the results obtained for mixed sample (average of 5 samples systematically distributed within the study area) are in ±1 standard deviation range from the average of 25 individual samples.

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.

Opis:: 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.
