Opis:
The study analysed short−term rhythm of radial increments of spruces from different elevations and their climate drivers. Two Norway spruce stands were chosen at the lower and upper montane forest belt in Roztoka Valley (DR) (1000−1050 m asl, 49°13 N, 20°04 E) and in Hala Gąsienicowa (HG) (1500−1550 m asl, 49°13 N, 20°04 E). 20 trees were sampled and one increment core was taken per tree. The sampled trees were dominant or co−dominant individuals without visible damage. To remove the age trend, the tree−ring widths values were standardized to annual sensitivity indices. Principal components analysis, bootstrapped correlation and pointer years analysis were used to classify sensitivity of investigated series and identify the climate factors, which determined annual variability of the radial increments. Pointer years were also determined by using interval trend method. The first principal component (PC1) accounts for 39% of the variance among all tree−ring series. The second component (PC2) accounts for 15% of the variance among the tree−ring series and divides the series into two groups. This grouping seems to express the lower and higher locations of the sites. The sensitivity series of spruces from both sites had different as well as similar features. These differences resulted from different tree's reaction to temperature in early spring and precipitation in spring and summer. The similarity of increment reactions of spruce from both sites was caused by their similar sensitivity to sunshine duration and precipitation in January, temperature in June and July, sunshine duration in June. Cluster analysis confirmed the impact of the climatic factors on differences of increment reactions of spruces. A number of the pointer years was higher at site located in the upper montane forest belt. Their chronology also consisted a stronger climatic signal. The climatic sensitivity which was specificity for a given climatic belt was recorded into individual tree series. For that reason, the tree−ring width series of trees are useful in the estimate of a climate−increment relationship. They can also be used to dividing dendroclimatic belts.

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 effect of the snow cover on the survival of beech seeds from the time seeds fell onto the ground until the appearance of seedlings was investigated during two seasons at the study sites in the Babiogórski National Park and in the Ojcowski National Park. The obtained results show that snow cover has influence on the shaping of a spatial pattern of seed survival, and on the appearance of germinated seedlings. However, no decisive influence of snow cover was shown on the appearance of seedlings. The drying of the germinated seeds is the main cause of their mortality.

Opis:
The aim of this study was to i) determine similarities and differences in the increment reaction of silver firs growing at different elevation, ii) identify climatic factors, which caused these response, and iii) determine dendroclimatic zones and identify a site, where a tree grew on the basis of tree−ring widths series. Studied stands were located in the Ustroń Forest District at the elevation of: 500−550 m a.s.l. (foothill zone, 18°59‵ E, 49°43‵ N) and 800−850 m a.s.l. (lower montane forest zone, 18°58‵ E, 49°43‵ N). In each stand 20 dominant firs were selected and one increment core per tree was taken. Tree−ring widths (fig. 1) were transformed into annual sensitivity index (fig. 2). Principal component analysis was used to reduce a number of original variables and classify the tree−ring series. Response function analysis was used to determine climate−radial increment relationships. The standardized series of firs on both sites were different in terms of the climate influence (fig. 3). The analysed trees responded differently to solar and thermal conditions in previous autumn and current summer as well as to pluvial conditions at the beginning of winter and in the second half of summer. The investigated firs had also common increment characteristics. The trees from both sites responded similarly to thermal, solar and pluvial conditions in February, solar and pluvial conditions in May and temperature in winter and summer (fig. 4). Climatic signal of each elevation zone was recorded by each tree and depended on the climatic conditions in given area. On the basis of standardized tree−ring series, dendroclimatic regionalization can be created and the stand, where a tree grew, can be identified.

Opis:
The paper compares the properties of Norway spruce (Picea abies (L.) Karst.) wood from stands growing in the lower and upper subalpine forest zone in terms of the tree−ring width, the share of latewood and the wood density. The investigation concerned material originating from plots established within the boundaries of the south−western incidence of spruce in Poland. Plots were located in the Sudety Mts. and in the Carpathians (tab. 1). On each plot fifteen Norway spruces were chosen and increment cores were sampled using the Pressler borer. The surface of the cores was smoothed and the tree−ring width was measured. The latewood zones were determined and the share of latewood was calculated. Then, the cores were divided into 2 cm sections, for which the relative wood density was determined. Tree−rings were wider in trees growing in the lower when compared with those from the upper subalpine forest zone (tab. 2). Weak negative correlation was revealed between the elevation and the tree−ring width (r=–0.308). The latewood share was slightly higher in trees from the upper than those from the lower subalpine forest zone (tab. 2). However, no statistically significant correlation between the latewood share and elevation was recorded. The wood density was slightly lower in trees from the lower than those from the upper subalpine forest zone (tab. 2), but the difference was not statistically significant. The correlation between the wood density and the elevation turned out to be insignificant.

Opis:
The aim of this paper is to present the properties of soils and topography conditions of Norway spruce forests growing on the limestone (Polysticho−Piceetum) in the upper part of the lower montane zone. The study was conducted in the Tatra Mts. (southern Poland) on six study plots reflecting the living conditions of spruce forest on limestone. On each plot the topography conditions were described, soil pits were dug and samples for laboratory analysis were collected. The following characteristics were determined in the soil samples: pH, the content of C and N, particle size, the content of Ca, Mg, Na and K, exchangeable acidity, aluminum content and hydrolityc acidity. For each study plot the stand characteristics were measured (diameter at breast height and height). The Soil Trophic Index for mountain areas (SIGg) was calculated on the basis of <0.02 mm fraction content, the sum of exchangeable base cations, soil acidity and the total content of N and C organic in the humus−mineral horizon. Polysticho−Piceetum stands in the upper part of the lower zone between 1000 and 1200 m above sea level developed in the unique geomorphological and geological conditions. They covered very shallow weathered fragments of limestone or steep slopes with fine−grained scree of carbonate rocks. Rendzic Hyperskeletic Leptosols (Humic) and Calcaric Lithic Leptosol are soils typical for analysed spruce stands. Character of site was reflected in the SIGg values that ranged between 15 and 20. The moder−mull and tangel−mor humus type was found on the majority of the investigated plots. Low fertility of soil was confirmed by the site index of analysed stands (IVth and Vth class).
