    Opis:
    The paper presents the inventory of place names (toponyms) connected to European beech (Fagus sylvatica L.). This tree species reaches its eastern distribution limit in Poland and covers around 5.9% of forest area in the country. Due to the fact that its occurrence depends mostly on climatic conditions it is present on the west, north and south, but not in the central and eastern part of Poland. The aim of this study was to compare, using geographic information system (GIS) tools, spatial distribution of toponyms derived from the core ‘buk’ (i.e. beech in Polish) with present occurrence of this tree known from botanical studies, and its natural limits described in the literature. Thanks to National Register of Geographical Names 1314 topographic objects names derived from beech were determined and classified into several groups of origin. Around 38% of phyto−toponyms are names of settlements or their parts. The results of spatial analysis of this objects show great similarity with present day distribution of this species in Poland. As much as 75% of them are located within the area presently covered with Fagus sylvatica (according to European Forest Genetic Resources Program) and around 92% within its range limit. Some regions where the density of phyto−toponyms is quite high and which nowadays are covered by other species than beech were also delimited (e.g. Dalkowskie Hills or Bytów Lakeland). This results suggest that European beech may be the natural representative of local dendroflora, but due to the changes in land cover it was replaced by other species. This hypothesis seems to be confirmed by palaeoecological studies. Huge similarity of distribution of toponyms derived from beech and distribution of this tree known from the literature shows that this method have a great potential as a reliable, simple and cheap proxy in studies on the spatial range of the species.

    Opis:
    The paper reviews the current knowledge about the genetic variation, glacial and postglacial history of Polish populations of silver fir (Abies alba Mill.). This species occurs in the mountainous forests of central and southern Europe, from the Pyrenees up to the Balkans, where it is important from both ecological and economical points of view. The current knowledge about glacial and postglacial history of fir has been obtained from palynological and genetic studies. During the last ice age A. alba survived in the refugia in southern Europe, the central Apennines, the south of the Balkan Peninsula and the Central Massif in France. Two other refugia remained isolated – one in Calabria in the south of the Apennines and one in the Pyrenees. Furthermore the most likely routes of postglacial recolonization of silver fir as well as the introgression zone between them have been identified. In Poland, silver fir reaches the north−eastern border of its natural range. Several earlier studies based on isozymes and DNA markers (mitochondrial and chloroplast) have reported that the Polish populations of fir are characterized by lower levels of genetic variation within populations and higher genetic differentiation between them than other coniferous species. Fir probably migrated to Poland from two glacial refugia located in the Balkan and Apennines Peninsula. Notwithstanding, a recent study on Polish silver fir populations carried out with mtDNA marker, strictly maternally inherited, indicated that the species migrated to the Polish territory from the refugium in western Europe. However, this study did not take into account the possibility of participation of pollen pool of Balkan origin in the formation of the Polish populations of fir. Until now, there have been only a few reports concerning the gene pool of fir in Poland. Therefore, it is necessary to supplement the knowledge about its genetic variation. In the course of several episodes of silver fir decline during the past century, its populations have decreased in size and currently are scattered throughout the entire European range. Reliable information on the distribution of genetic variation is a prere−quisite for proper management of forest genetic resources in a short−term and long−term perspective. The recognition of the existing genetic diversity is also the preliminary phase in development of an effective strategy for conservation of forest tree species gene pools.

    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:
    A monitoring network was set up in 2002 in order to define the distribution range of Ips duplicatus in mountain Norway spruce stands in southern Poland. Borregard pipe traps baited with synthetic pheromone Duplodor (Chemipan, Poland) were installed on 70 locations situated above 600 m a.s.l. in Carpathians and Sudeten. The occurrence of I. duplicatus was confirmed in 17 locations in the western part of Carpathians, including those located around 1000 m a.s.l., while no beetles were caught in the eastern Carpathians nor in the Sudeten. The distribution range in Polish mountains is adjacent to those in northern Slovakia and northern Moravia (Czech republic).

    Opis:
    Presented research investigates the possibility of applying the newest, free available satellite images Sentinel−2 for the automation of land use/cover (LULC) mapping in reclaimed areas, mainly in the aspect of monitoring forested areas. The study was performed for the former sulphur mines: ‘Machów’ (871.7 ha of the dump area after the opencast strip mine) and ‘Jeziórko’ (216.5 ha of the afforested area after the borehole exploitation). These areas are characterized by a diverse terrain structure and vegetation cover as the result of reclamation. The applied directions of reclamation were agro−forestry for the Sulphur Mine ‘Machów’ and forestry for the Sulphur Mine ‘Jeziórko’. We verified whether processing of Sentinel−2 data allows for reliable LULC classification – mainly identification forested areas in relation to the LULC mapping prepared by manual vectorization of orthophotomaps. Obtained classification results for Sentinel−2 data were also compared to the results of Landsat 8 images processing. The results of Sentinel−2 images classification showed correct graphical representation of the LULC classes, especially forested areas, in the relation to the results of applied on−screen vectorization of aerial orthophotomaps – better than results of the Landsat 8 images processing. The area of the mail class ‘Forests’ as a result of classification Sentinel−2 and Landsat 8 images compared to the results of manual on−screen vectorization of the orthophomaps shows differences: 5.4% – Sentinel−2, 12.8% – Landsat 8 for Sulphur Mine ‘Machów’ and 1.8% – Sentinel−2, 8.8% – Landsat 8 for Sulphur Mine ‘Jeziórko’. Research indicates the possibility of automation of LULC classification using Sentinel−2 images. It could be very useful for LULC changes monitoring in reclaimed areas, mainly in the aspect of forested areas mapping as a result of way of reclamation.
