    Opis:
    The available phytosociological literature were reviewed and compared with 12 original relevés made on representative of habitats of fir trees in the study area. Only in the eastern part of the Sudety Mts. silver-fir is still important forest tree. It is found most frequently in potential sites of acidophilic beech forest, which vegetation is now strongly transformed because of planting them with spruce. Typical, mainly acidophilic beech forest takes second place (in respect of frequent occurrence). Oak-hornbeam forest take third position.

    Opis:
    Knowledge of the vegetation and the monitoring of its changes in preserved areas is an essential part of effective conservation policy and management. The aim of this study was to assess the effectiveness of traditional methods of conservation of silver fir forests. The study analyses the changes in the structure and species composition of a temperate forest excluded from the commercial silvicultural management for 50 years, and since then protected as a nature reserve. The study is based on a comparative analysis of phytosociological reléves made on permanent plots in 1961, 1982, 1994 and 2011. PCA and ecological indicator values were analyzed, as well as characteristic species based on an indicator value (IndVal) index. Results revealed significant and dynamic changes in the forest structure and composition. The mixed coniferous-broadleaved forest with Abies alba and diverse ground flora, considered in the 1960s as valuable and worthy of conservation, was found to have been anthropogenically transformed and unstable. Significant reduction in the human impact was followed by spontaneous regeneration of oak–hornbeam forest. However, the directional process of changes in vegetation was modified by such silvicultural treatments as selective cutting of trees and gap creation, all intended for silver fir maintenance. The results show that Carpinus betulus effectively outcompeted Pinus sylvestris, Picea abies, Quercus robur and A. alba. Changes in the forest overstory and understory caused temporal changes in the habitat conditions reflected in changes in the ground vegetation composition. The proportion of light-demanding and oligotrophic species significantly decreased, while the contribution of species with a wide ecological amplitude, i.e. more shade-tolerant and nutrient-demanding – increased. The share of A. alba was reduced. Species defined in this study as most valuable, should be actively protected, or selection of conservation targets should be re-evaluated.

    Opis:
    Data from floristic publications, forest management records, comprehensive questionnaires and original field research were used to assess the silver fir resources in the Sudety Mts. Fir trees older than 50 years were recorded in over 2000 localities but the mean number of individuals per locality was only about 15. The generally low number of fir trees and their considerable dispersion are the major causes of the poor reproduction of the studied species in the Sudety Mts. In that region, silver fir should receive special treatment and, if possible, excluded from logging plans. Current and projected activities concerned with fir protection are described briefly.

    Opis:
    The study presents the structure and floristic composition of mixed fir forest at the northern range limit of European silver fir (Abies alba) in Poland. Phytosociological data were collected in the forest reserve “Murowaniec”,which was established to protect mixed forest ecosystems with a large contribution of fir trees. Changes in floristic composition of these coniferous forests in the last 40 years were discussed. Protective measures are suggested in this paper, aiming at conservation of the forest ecosystems of the reserve.

    Opis:
    Hericium flagellum (Scop.) Pers. is considered a rare, wood-decaying fungus that occurs on coniferous trees, predominantly on silver fir (Abies alba). In this paper, a new locality of H. flagellum in Wielkopolska Voivodship is presented, along with the macro- and micromorphological features of the collected specimens. Basidiomata of H. flagellum were found in November 2016 and 2017 in the “Olbina” nature reserve (ATPOL Dc-97, Kalisz Forest District), located in a continental mixed coniferous forest close to the northern border of the natural range of silver fir. In 2016, H. flagellum was found growing in the hollow of an old stump of silver fir, and in the following year, this fungus was recorded on a fallen log of silver fir. The implications for conservation are briefly presented. Prospects of further development of the basidiomata of H. flagellum in the “Olbina” reserve are also discussed.

    Opis:
    Numerous examples of silver fir stands growing outside its geographical range in northern Poland suggest that this species could be used in a greater extend in creation of managed forest stands. Climatic conditions could potentially constrain the use of this species in some parts of country. The objective of this work was to determine the potential climatic range of Abies alba in Poland. The bioclimatic envelope models were used to identify areas in which selected climatic variables show the same range of variability as observed within natural range of this species. Climatic data with 10' spatial resolution were used. The outcome of the analysis depends to large extent on the demarcation of natural range (in which the variability of tolerable climatic conditions is assessed). The model basing on the climatic conditions in whole natural range of silver fir in Europe suggest that almost whole area of Poland is suitable to fir, but models basing only of climatic conditions in Polish part of its natural range are much more conservative. In the last case the difference in extent between natural range and potential climatic range was smaller. As genetic variability of Polish fir populations is rather low, they are supposed to have constrained adaptative abilities. Forest managers should not focus on planting silver fir outside its natural range, but they rather should consider reintroduction of fir in parts of natural range from where it retreated in 20th century.

    Opis:
    The silver fir (Abies alba Mill.) in the area of Wał Trzebnicki is at the northern limit of its distribution in western Poland. This study was performed in three nature reserves with protected silver fir populations. The stands in these reserves were mixed, with complex spatial structure and abundant tree regeneration. The proportion of fir in stands was around 16% of DBHS, the age of trees reached around 130 years. The silver fir occurs mainly in the sapling stage, whereas the number of seedlings was very low. The results of this study show the influence of forest floor vegetation as well as litter type on the emergence of fir seedlings. The seedlings density was compared with the results of other studies from different geographical areas and stands type in Poland.

    Opis:
    Mitochondrial DNA marker was applied to 10 populations of silver fir from Poland and one from Belarusia. These populations were located within and beyond the natural range of silver fir. The marker exhibited two highly conserved alleles (first – 230 bp and second – 150 bp) based on an insertion−deletion of 80 bp in the fourth intron of the mitochondrial nad5 gene. The geographical distribution of the maternally inherited mitochondrial variation is known to support the existence of at least two refugia with two recolonizing maternal lineages remaining largely separated throughout the range. Our results provide that in all studied populations the first allele was discovered. Therefore we postulate that the silver fir migrate to Poland from the refugium in western Europe (probably from central Italy).

    Opis:
    The paper provides information concerning the growth of pine, spruce, oak, beech and fir stands based on the research conducted by the European Forest Institute in a number of the European countries and in Poland. Noteworthy i.a. is the increase in volume increment of spruce and pine in some stands in Germany up to 250% of the values given in the yield tables. Since the early fifties of the past century beech and sessile oak in Bavaria have exhibited an increase in the height growth and volume increment. Their values markedly exceed those provided in the tables. Fir, similar to spruce, pine and beech shows the reduction in the increment and dieback in the regions under heavy industrial pollution. However in other regions under the impact of air pollution the response of pure and multispecies stands with the share of fir was positive. In Poland, a rapid decline in the dbh increment in three tree species (fir, spruce, pine) in the seventies was greater than in the sixties. In 1981−1989, fir showed a favourable growth in diameter; this positive tendency was noticed in the whole range of fir distribution in Poland, though the increment did not return to the level before its decline. The pine increment regenerated after 1990. The poorest increment was found in spruce in the eighties following its collapse in the seventies (Żywiecki and Śląski Beskid).
