Opis:
The study analysed the causes of the annual variation of tree−ring widths of silver fir and white fir. The partial populations of both fir species has been growing for over 100 years in Rzepin (western Poland) in a fresh broadleaved forest site. We assumed that the year−to−year changes of the size of radial increment presents sensitivity of trees to local climate factor. The period from 1931 to 2015 was analysed. We found that the silver and white firs had high homogeneity of radial growth responses and sensitivity to year−to−year changes of weather conditions. Warm November of the previous year, short winter and high air temperature in August had positive influence on the size of their radial increment. Moreover, precipitation in February, April and July of the year of tree−ring formation contributed to wider tree−ring. The white fir was highly resistant to winter frost in contrast to the silver fir. In addition, this fir species preferred cold springs. Furthermore, the silver fir suffered from overabundant precipitation in August. The climate conditions of western lowland part of Poland were not a limiting factor for growth of both species because the studied populations achieved the highest site index class.

Opis:
Height-diameter models define the general relationship between the tree height and diameter at each growth stage of the forest stand. This paper presents generalized height-diameter models for mixed-species forest stands consisting of Norway spruce (Picea abies Karst.), Silver fir (Abies alba L.), and European beech (Fagus sylvatica L.) from Slovakia. The models were derived using two growth functions from the exponential family: the two-parameter Michailoff and three-parameter Korf functions. Generalized height-diameter functions must normally be constrained to pass through the mean stand diameter and height, and then the final growth model has only one or two parameters to be estimated. These “free” parameters are then expressed over the quadratic mean diameter, height and stand age and the final mathematical form of the model is obtained. The study material included 50 long-term experimental plots located in the Western Carpathians. The plots were established 40–50 years ago and have been repeatedly measured at 5 to 10-year intervals. The dataset includes 7,950 height measurements of spruce, 21,661 of fir and 5,794 of beech. As many as 9 regression models were derived for each species. Although the “goodness of fit” of all models showed that they were generally well suited for the data, the best results were obtained for silver fir. The coefficient of determination ranged from 0.946 to 0.948, RMSE (m) was in the interval 1.94–1.97 and the bias (m) was –0.031 to 0.063. Although slightly imprecise parameter estimation was established for spruce, the estimations of the regression parameters obtained for beech were quite less precise. The coefficient of determination for beech was 0.854–0.860, RMSE (m) 2.67–2.72, and the bias (m) ranged from –0.144 to –0.056. The majority of models using Korf’s formula produced slightly better estimations than Michailoff’s, and it proved immaterial which estimated parameter was fixed and which parameters were free.

Opis:
The aim of the study was to evaluate the sensitivity of silver fir (Abies alba Mill.) from the Rudnik Forest District on the selected meteorological elements and to develop a chronology of local tree-ring width and the annual sensitivity. Based on the analysis, the site chronology of silver fir was developed and the strength of the relationship between the climate components and the width of annual rings was calculated. In addition, we examined the degree of homogeneity of short-term incremental response, rated the representativeness of the chronology and climate signal strength. Having analysed the indicator years, namely 1932–2013, we concluded that the growth of firs was positively influenced mainly by air temperature in winter, and to a lesser extent, by precipitation in spring and summer. The main factors that limit its growth are cold winters, cool and low rainfall summers, and rainy springs.

Opis:
The research was conducted in beech−fir and beech stands in the territory of the Babiogórski and Ojcowski national parks. The obtained results showed that the density of seedlings after the autumn seed fall was small. The seed fraction from which seedlings emerged did not exceed 8%. In the Babiogórski National Park, no spatial relationship was found between seed and seedling abundance. However, such relationship was found in beech and sycamore in the Ojcowski National Park during one season. This was associated with a lower density of seed predating rodents in the forests around Ojców than on the Babia Góra and the specificity of the environmental providing a wide variety of living conditions for small mammals.

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 occurrence of silver fir (Abies alba Mill.) outside its natural distribution limits in the Baltic and Wielkopolsko−Pomorska Natual−Forest Regions depends mainly on anthropogenic factors and climatic conditions: annual precipitation sum and air temperature amplitudes. Dispersed stations in north−western and western Poland may indicate the expansion of its natural range possibly as a result of current climatic changes. The condition of mature stands and natural regeneration in the examined sites were good. For efficient silvicultural management of fir outside its natural range it is advisable to apply the cutting system with longer regeneration period and effectively protect the existing natural regeneration.

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.
