    Opis:
    The paper presents the analysis of relations between diameter increment and climatic factors in silver fir stands in the Zagnańsk Forest District (central Poland). Despite growth rate similar to the observed in other parts of Poland, firs form the Świętokrzyskie Mountains show different climatic driving forces of the increment process. Temperature in March, late summer and September as well as precipitation in May and summer in the year of tree−ring formation, and in August of the previous year turned to be the most important factors that shape diameter increment of analysed trees.

    Opis:
    The paper presents an analysis of height growth phases of silver fir from the Świętokrzyskie Mountains. Basing on bilateral relations between average and current height increments, age of their culmination and duration of main (juvenile and sprouting) phases was determined. Empirical data consisted of 61 sample trees that were subjected to the stem analysis. Juvenile stage of fir height growth lasts 30 years, while sprouting phase is quite long as it lasts 45 years on average. Mean age when analyzed trees reach the culmination of current and average height increment equals 50 and 70 years respectively. Course of height growth of fir resembles this of beech, which can be explained by shade tolerance of these species.

    Opis:
    The study assesses the damage to silver fir from the canopy layer in the stands of the Świętokrzyskie Mountains (central Poland) using three methods. The suitability of these methods was also analysed by calculating the correlation between increment of the diameter at breast height (DBH) and the level of damage. In total we investigated 240 trees. The first analysed method involves tree defoliation. The mean defoliation of sample accounts for 47.8%, while majority of the trees were found to be within 2nd damage class (fig. 1). Absolute and relative DBH increment does not correlate with tree defoliation strongly (tab.). The next method is based on the assessment of the average tree damage index W that takes into account defoliation, top condition and vitality. In general, analysed trees were found to have reduced height growth and both branching in the top (fig. 2) and central (fig. 3) section of the crown. Inclusion of the secondary crown in the assessment of tree damage resulted in an increase in the vitality of the whole crown (fig. 3). The assessment of damage based on index W showed that largest proportion of trees was within moderate damage and the value of the damage index was lower than in method based exclusively on defoliation. The last method (morphological−incremental) combines the method based on damage index W with DBH increment (index Wz, formula 3). In the period 1971−1985, most of the fir trees reacted negatively to the environment changes (growth reduction), while the proportion of trees with positive responses decreased. In the period 1976−2000, the proportion of trees with negative response decreased, while the proportion of firs with positive and neutral responses increased (fig. 5). The period 2001−2015 faced the dominance of trees showing neutral growth responses, the proportion of trees with positive responses was fairly high, while the proportion of trees with negative responses was the smallest. The highest value of the correlation coefficient (r=–0.661) was found for the correlation between the relative 10−years DBH growth and damage index Wz2(tab.). Of the three discussed damage assessment methods, this method is therefore considered the most accurate.

    Opis:
    Preliminary studies on frost−hardiness of the current year shoots of silver fir were conducted between the autumn of 1999 and the spring of 2000 on the 20−25 year old saplings, collected in 13 sample plots distributed throughout the Świętokrzyski National Park.The diffusion of electrolytes from shoots and needles kept in a freezer at the temperature of −33°C was analysed using the Dexter's (1932) method. The highest degree of frost−hardiness of shoots and needles was found in February. In spring the resistance to low temperatures declined faster in shoots than in needles.The investigations showed significant differences in the frost−hardiness of young silver firs from different sample plots.

    Opis:
    In Poland, the majority of silver fir stands is characterised by a single−layer stand structure. The current silvicultural activities aim at obtaining multilayer stands, which requires a clearer definition of the structure, and more precisely, a better knowledge of the pattern of diameters at breast height (DBH) distribution. The aim of the research was to develop a pattern of DBH distribution of trees in a multilayer silver fir stand in the Świętokrzyskie Mountains (central Poland) using the BDq method, through the mathematical determination of function parameters, including the productive capacity of the habitat. The application of this pattern will allow the selection of the management methods aimed to obtain and then maintain model stands with a different layer structure. The research was based on the empirical material collected in 56 stands that were characterized by both a single− and a multi−layered structure. They grew in coniferous forest habitats, mostly in the upland mixed coniferous forest, upland mixed deciduous forest and upland deciduous forest or mountain forest. One big (up to 1 ha) or 3−5 smaller (0.04 ha) sample plots were established in each stand in which diameters at breast height of all trees and heights of usually 25 trees, selected from the entire range of diameters, were measured. These were used to determine the height growth curve equation coefficients and then the height of each tree. For each stand the basal area was calculated and a graph for DBH distribution was prepared. Site index was established using the original empirical equation. In order to develop a model for multilayer fir stands, individual parameters of the equation 5, such as the basal area (B), the target diameter at breast height (D) and the coefficient q were to be determined using the BDq method. Taking into consideration only stands with one−tailed DBH, individual parameters of the function were found to be associated with site index. Empirical equations were developed for the determination of B and D, and, based on the DBH distribution graphs, coefficient q associated with site index was also calculated (tab.). The developed DBH distribution pattern is a mathematical description of the target fir stand. When the value of stand parameters approaches those of the model stand, it should be managed using the shelterwood cutting system, which results from the spatial variation in the stand height structure, and consequently from the need for different silvicultural treatments in different stand fragments.

    Opis:
    The paper presents the dendrochronological analysis of silver firs (Abies alba Mill.) growing in the canopy layer of the forest stands. We searched for the similarities in the rhythm of radial growth of studied trees and we analysed the response of these stands to the increment disturbances related to the occurrence of adverse climatic factors and the pressure from industrial pollution. The research material was collected in 30 pure and uneven−aged silver fir stands located in the Świetokrzyskie Mountains (central Poland). We investigated the effect of age of the stands and the conditions for their growth (location, forest habitat type) on an average tree−ring width. In order to detect similarities in the rhythm of radial growth of the surveyed stands, we grouped the raw chronologies by the means of the cluster analysis, using Ward's agglomeration procedure with 1−r distance (r – Pearson correlation coefficient). We assessed the incremental response of the investigated stands to the disturbances (situations of significantly reduced radial growth) using indicators of resistance, recovery and resilience proposed by Lloret et al. [2011]. We also studied the influence of the stand age and the forest habitat type on the response of analysed for stands to the detected disturbances. The shortest chronology consisted of 94 tree−rings, while the longest one of 137. Average length of the obtained silver fir chronologies was 119 years. Older fir stands characterised with narrower rings (r=–0.451, p=0.012). Neither the location, nor the forest habitat type are the factors determining the similarity of the rhythm of radial growth of silver firs from the Świętokrzyskie Mountains (p=0.243 and p=0.967 respectively). The extreme climatic conditions responsible for the majority of the short−term (one−year−long) incremental depressions are the factor of regional importance, which affects the growth of investigated trees. Older stands characterized with better possibilities of increment recovery after the disturbance than younger stands (p<0.001), which may be a result of the production of secondary crowns. No consistent differences in the indices of resistance and resilience were found among analysed stands.

    The objective of the study was to evaluate the health condition (defoliation) and vitality of Polish larch, fir, beech, pine and two native oak species growing on Chełmowa Góra in the Świętokrzyski National Park. Sample trees were selected using a survey sampling, simple random sampling without replacement (lpbz) and two−stage sampling (with lpbz on both stages) (l2s: I−lpbz, II−lpbz) were employed. The spatial distribution of the fractions of trees in defoliation and vitality classes in the stand allowed to categorize the examined species with regard to their health condition (from ‘best’ to ‘worst’) in the following order: Polish larch, beech, pine, oaks and fir (in the case of defoliation) and Polish larch, beech, pine, fir and oaks (for vitality). The estimation errors for the fractions of trees in defoliation and vitality classes ranged from 0.013 to 0.076.
