Opis:
Exceedingly violent winds can result in windbreak and in windthrow. It has happened in summer of 2002 in Pisz Forest District (north part of Poland). Strong wind damaged about 30 000 hectares of pine forest. In most situations, damaging wind resulted in windthrow rather than windbreak. In total 30 plots were selected for the studies, 15 plots in Pisz forest (damaged by wind) and 15 control plots in Maskulińskie District Forest (not damaged by wind). There were distinguished 5 age variants of stands, all of them in three recapitulations. The five age classes of stands were: I class (20−30 years old), II class (30−40 y.), III class (40−50 y.), IV class (50−70 y.) and V class (above 70 years old). In total 4 000 carabids individuals belonging to 46 species were caught during studies. The wards analy− sis showed substantial diference of carabid assemblages occurring in damaged and non damaged forest. In damaged forest, small zoophages, hemizoophages, an open area or eurtyopic species, xerophilus species were frequently observed. Substantial differences in mean individual biomass of assemblages occurring in damaged and non damaged forest were also observed.

Opis:
Owing to the unpredictability of changes in a habitat, a silvicultural aim should be treated as a "vision" of the future stand and adjusted in the course of its development. To meet the rational principles of stand conversion, it is necessary to fully use the natural processes occurring in forest ecosystems. More attention should be given to the species of early succession stages, which are better adapted to the changing habitat conditions, and richer species composition should be ensured to disperse silvicultural risks.

Opis:
The analyses of 4 permanent study plots located in the Białowieża forest (NE Poland, at 52º43´ N, 23º50´ E) were carried out 4 times, first time in 1973 or 1974 and next in 1985, 1998, 2008. The paper presents the results of a long–term study on natural forest dynamics in two forest communities: raised-bog pine forest of the association Ledo-Sphagnetum magellanici Sukopp 1959 em. Neuhäusl 1969 and transitional bogs represented by the boreal spruce forest Sphagno girgensohnii-Piceetum Polak. 1962. On each measurement date the DBH of all trees were recognized. At the same time, stems of shrub species as well as tree species with the height lower than 1.3 m were counted within the experimental areas. During the study period the structure of stands changed significantly. The major change observed on raised bog sites was an increase in numbers of Betula spp., Picea abies (L.) H. Karst. and Quercus robur L. After 34th-year of observations the boreal spruce forest stand partly passed the terminal phase and regenerated. New species occurred in the stands, especially in their lower layer, are typical for oak-lime-hornbeam forest, such as e.g. Carpinus betulus L., Q. robur, Acer platanoides L. Rapid development of Corylus avellana L. was also observed. During last decades, the decrease in the number of Pinus sylvestris L. trees has been observed. The results of analyses of stand data in four research periods show that the wetland habitat of the Białowieża forest has been a subject to the processes of succession conditioned by environmental changes such as desiccation through lowering of the water table as well as climatic changes entailing inter alia an increase of the air temperature and a decrease of precipitation.

Opis:
The purpose of this study was to determine the spatial structure of vegetation on the repository of the mine “Fryderyk” in Tarnowskie Góry. Tested area was located in the Upper Silesian Industrial Region (a large industrial region in Poland). It was a unique refuge habitat – Natura2000; PLH240008. The main aspect of this elaboration was to investigate the possible use of geotechniques and generally available geodata for mapping LULC changes and determining the spatial structure of vegetation. The presented study focuses on the analysis of a spatial structure of vegetation in the research area. This exploration was based on aerial images and orthophotomaps from 1947, 1998, 2003, 2009, 2011 and airborne laser scanning data (2011, ISOK project). Forest succession changes which occurred between 1947 and 2011 were analysed. The selected features of vegetation overgrowing spoil heap “Fryderyk” was determined. The results demonstrated a gradual succession of greenery on soil heap. In 1947, 84% of this area was covered by low vegetation. Tree expansion was proceeding in the westerly and northwest direction. In 2011 this canopy layer covered almost 50% of the research area. Parameters such as height of vegetation, crowns length and cover density were calculated by an airborne laser scanning data. These analyses indicated significant diversity in vertical and horizontal structures of vegetation. The study presents some capacities to use airborne laser scanning for an impartial evaluation of the structure of vegetation.
Celem badań była ocena struktury przestrzennej roślinności porastającej zwałowisko odpadów kopalni ”Fryderyk” w Tarnowskich Górach, położone na północnym skraju Górnośląskiego Okręgu Przemysłowego. Teren, na którym znajduje się zwałowisko należy do sieci Natura 2000 (PLH 240008). Głównym aspektem poruszanym w opracowaniu było określenie możliwości wykorzystania ogólnie dostępnych geodanych dla opracowywania map pokrycia i użytkowania terenu zwałowiska oraz określenia struktury roślinności na tym obszarze. Analizowane materiały to zdjęcia i ortofotomapy lotnicze z lat: 1947, 1998, 2003, 2009, 2011 oraz dane z lotniczego skanowania laserowego (z projektu ISOK, 2011). Efektem opracowania było określenie charakterystyki przestrzennej roślinności na zwałowisku kopalni ”Fryderyk”. Analizy wykazały stopniową ekspansję roślinności na powierzchni hałdy. W 1947 roku 84% powierzchni terenu badań pokryta była przez roślinność niską a w roku 2011 roślinność wysoka zajmowała już około 50% obszaru zwałowiska. Analizy wykazały znaczne zróżnicowanie w poziomej i pionowej strukturze roślinności. W opracowaniu przedstawiono możliwości wykorzystania danych z lotniczego skanowania laserowego dla obiektywnej oceny struktury roślinności.

Opis:
The secondary succession pattern observed on an arable field abandoned since 1974 in Tilio-Carpinetum habitat is described and disscussed. Results obtained during 36 years of study confirm that succession on an abandoned field leads from a typical segetal community to the formation of a juvenile treestand composed of pioneer species. Our study supports the view that succession is a process which is largely dependent on the initial conditions and surrounding vegetation. The results indicate that some species can modify the course of this process, accelerating or slowing it down. Limitations of the method and prognosis of future vegetation development are also discussed.

Opis:
The paper presents the studies involving analysis of changes in shape of parcels of arable land under the influence of forest succession. The object of the research is the village Grębosze located in Świętokrzyskie voivodeship. The study material will cover all arable land existing in the studied village. The source of data were numerical registry maps from 1998 and 2013. The basic element of research, enabling comparison of changes in the efficiency of the production process are continuous parts of the parcels covered by one form of use. In the course of the output data processing and determination of the necessary technical parameters for the tested surface elements, the specialized tools and statistics were used. The studies were related to the evaluation of formation of these surface structures on the basis of their shape meter in the form of the so-called costs of cultivation. The obtained results make it possible to tell, to what extent the changes resulting from the consequences of the secondary forest succession influence the process of cultivation of neighbouring arable land.
W pracy przedstawione zostały badania obejmujące analizę zmian ukształtowania parcel na gruntach ornych pod wpływem sukcesji leśnej. Obiektem badań jest sołectwo Grębosze położone w województwie świętokrzyskim. Materiał badawczy obejmie wszystkie grunty orne występujące w badanej wsi. Źródłem danych były numeryczne mapy ewidencyjne z lat 1998 i 2013. Podstawowym elementem badań, umożliwiającym porównanie zmian efektywności procesu produkcyjnego są ciągłe części działek ewidencyjnych objęte jedną formą użytkowania. W procesie przetworzenia danych wyjściowych oraz określenia niezbędnych parametrów technicznych badanych elementów powierzchniowych zastosowano specjalistyczne narzędzia informatyczne i statystyczne. Szczegółowe badania dotyczą oceny ukształtowania wspomnianych struktur powierzchniowych na bazie miernika ich ukształtowania w postaci tzw. kosztów uprawowych. Uzyskany wynik umożliwia stwierdzenie, w jakim stopniu zmiany wynikające z następstw wtórnej sukcesji leśnej wpływają na proces uprawy sąsiednich gruntów ornych.

Opis:
In Central Europe, deforestation led to a reduction of forest area by almost 80%, compared to the original area, by the beginning of the 20th century. At this point in time, a period of intensive reforestation began in an effort to restore forest areas. This process of reforestation, especially on post-agricultural land, continues to this day. This article examines reforestation and natural regeneration on former farmland and the factors that influence the current state as well as the future growth of the forest. Ancient and contemporary views on the functioning of stands on post-agricultural land created by both, natural and forced succession (i.e. afforestation), are recalled. In Poland, this issue primarily concerns managed state forests, which cover an area of over 2 million hectares. We discuss the differences in the development of these stands resulting from the history of agricultural cultivation, the type of afforestation, the influence of environmental factors as well as biotic threats to their development. Furthermore, the need to change the silviculture-, protection- and endowment-based approach to forest management in stands on post-agricultural land is highlighted.

Opis:
T he paper deals with the succession of basidiomycete macrofungi on abandoned farmland. T T he research was carried out in the unique complex of old fields of different age located on the southwest edge of the Białowieża old-growth forest (NE Poland). T T hese lands undergo spontaneous secondary succession leading to formation of a continental fresh pine forest. Regular observations of basidiomata in 16 permanent plots (11 plots of 1000 m2, 5 plots of 400 m2) representing initial, optimal and terminal stage of vegetation development from psammophilous grassland to a pine forest with 100-year-old tree stand were conducted for three years. Soil and vegetation analyses were also carried out as well as quantitative examination of ectomycorrhizae in root samples. T he series yielded 300 species of macromycetes (including 6 collective taxa) found in permanent plots plus 18 species outside the plots. T T he species composition, spatial distribution of sporocarps, and quantitative structure of fungal communities changed along the successional gradient. Increasing diversity of fungi resulted from persistence of species typical of open areas and species associated with younger trees, as well as accumulation of species associated with older trees and more developed stands. Some species typical of younger phases were replaced with species arriving later in the chronosequence. Species usually occurred long before and after attaining maximum abundance and frequency. Species associated with certain periods of vegetation development could be distinguished, as well as species accompanying the phytocoenoses regardless of their developmental stage. Patterns in structural changes of the fungal community, e.g., in number of species, abundance, frequency and production of carpophores, could also be recognised. T T hey were different in ectomycorrhizal and in saprotrophic fungi. T T he occurrence of the former was influenced mainly by the presence of symbiotic trees and their age, stand structure and soil properties, while occurrence of the latter was affected by microclimatic factors and by diversity of accessible substrates. Changes in fungal communities were consistent with vegetation changes, but were also specific to this group of organisms.

Opis:
The role of image classification based on multi-source, multi-temporal and multi-resolution remote sensed data is on the rise in the environmental studies due to the availability of new satellite sensors, easier access to aerial orthoimages and the automation of image analysis algorithms. The remote sensing technology provides accurate information on the spatial and temporal distribution of land use and land cover (LULC) classes. The presented study focuses on LULC change dynamics (especially secondary forest succession) that occurred between 1974 and 2010 in the Błędów Desert (an area of approx. 1210 ha; a unique refuge habitat – NATURA 2000; South Poland). The methods included: photointerpretation and on screen digitalization of KH-9 CORONA (1974), aerial orthoimages (2009) and satellite images (LANDSAT 7 ETM+, 1999 and BlackBridge – RapidEye, 2010) and GIS spatial analyses. The results of the study have confirmed the high dynamic of the overgrowth process of the Błędów Desert by secondary forest and shrub vegetation. The bare soils covered 19.3% of the desert area in 1974, the initial vegetation and bush correspondingly 23.1% and 30.5%. In the years 2009/2010 the mentioned classes contained: the bare soils approx. 1.1%, the initial vegetation– 8.7% and bush – 15.8%. The performed classifications and GIS analyses confirmed a continuous increase in the area covered by forests, from 11.6% (KH-9) up to 24.2%, about 25 years later (LANDSAT 7) and in the following 11 years, has shown an increase up to 35.7% (RapidEye 2010).

Opis:
In July, 1992, fire swept through the Jelonka Reserve (52o35'33"N; 23o22'10"E). Litter, herbs layer and juniper shrubs were razed and the tree trunks of Pinus sylvestris and Populus tremula damaged, which resulted in their death the following year. Five research plots of 25 m2 each were established in the post-fire area. The species present there and their degrees of coverage were listed on the Londo scale between 1993 and 2002. The calculation of average degrees of coverage for individual populations allowed for the establishing of a chronological pattern of post-fire succession. The following findings have been made: 1) the primary function in colonization belongs to species of guerilla strategy of growth whose dormant buds survived fire underground (Holcus mollis, Calluna vulgaris and Populus tremula) or phalanx strategy of growth (Corynephoms canescens); 2) the dominants of the initial succession stage are perennial grasses, not therophytes; 3) the spatial pattern of succession is influenced by the occurrence of H. mollis or C. canescens in a particular location; 4) the initial stage terminates with the occurrence and further growth of C. vulgaris clumps; the post-fire succession in the Jelonka Reserve attained a brushwood stage faster in comparison to secondary succession, formerly triggered by the cessation of cultivation on arable land.

Opis:
Białowieża Forest (BF) is widely known for its outstanding natural values. The debate about the management/protection model, able to maintain all relevant values of BF on a sustainable basis, has a very long history. Currently, the main role in this debate is played by groups and organizations claiming that the major threat for the biological richness of BF is related to local forest management. In this paper, an attempt is made to verify this thesis. The extensive literature research reveals that vascular plants are one of the most threatened (and best documented) groups of organisms occurring in BF. It was found, for example, that in case of Serratulo−Pinetum (one of the most important woodland community type occurring in BF) the floristic diversity declines at the rate 0.6 species per year. However, similar situation concerns many other groups of species (e.g. lichens) as well. The recession of many species does not take place in the managed part of the BF only. This problem concerns also the areas which, since a long time already, have been subjected to the strict protection, like the ‘Strict Reserve' of the Białowieża National Park (comprising ca. 7% of the BF, under strict protection since ca. 100 years). Several factors and agents responsible for the general deterioration of natural values of BF were identified. Among other things, many authors underline the negative impacts of natural, successional processes taking part in areas which were ‘liberated' from the direct human impacts. Such processes are a direct cause of loss among many herbaceous species, particularly helio− and termophilous plants. Another important reasons for decreasing trends in many important elements of the local biodiversity are: strong reduction of open and semi−open areas (disappearance of the so called ‘cultural landscapes'), climate change, air pollution, deer overabundance, compositional impoverishment of many tree stands, invasive species of plants and animals. In conclusion, there are many factors responsible for decreasing diversity of BF and most of them have nothing to do with the local forest management. To preserve possibly high levels of the natural values of BF for future generations, a wise and complex conservation strategy is needed. As many other similar examples from different places over the world clearly show, the core element of such a strategy should be the principle of active management approach and not the out of action principle of ‘doing nothing'.

Opis:
Number of carabid beetles, length of C. violaceus elytra and MIB of all carabids were studied subsequent to pitfall−trapping in 14 beech stands of increasing age (1−165 years) in Western Germany. The beech stands seemed to offer fairly constant feeding conditions for C. violaceus (and relatively small decrease in rather low level of degradation in the plantation). In total, 5,536 carabid individuals were trapped, which revealed significant increase of MIB (from 156.88 to 733.63 mg) following the logistic growth function. Due to incomplete degradation of the stands (on 'rich' soil and after using specific beech−harvesting techniques), there is a high baseline MIB at t=0 and an early onset of regenerative succession. The curve's gradient is steep and MIB reaches final value of about 650 mg in timber stands. Such high value may be explained by the good quality of loam soils in the area under study. In conclusion, logistic MIB function was calculated that describes regenerative beech succession on 'rich' soil and may help foresters to identify areas of disturbed succession.

Opis:
Ectomycorrhizal (ECM) fungi and their symbiotic associations with forest trees are among major drivers of key ecosystem functions such as carbon and nitrogen cycling, plant nutrient and water uptake from soil, plant-plant facilitation/competition and diversity regulation via common mycorrhizal networks. Through their functional traits and interactions with both abiotic and biotic environment, they also significantly affect the process of open land colonization by trees as well as vegetation succession coupled with soil and ecosystem development. Here we review the role of ECM fungi in the early primary and secondary succession following major anthropogenic disturbances. Based on the examples of mine spoils and post-agricultural lands, we demonstrate key ecosystem services provided by ECM fungi in the processes of forest restoration. We point out ecological mechanisms and adaptations which underpin ECM fungal community successional interactions, particularly life histories, dispersal, spatial structure, host preferences, and sensitivity to environmental filters. We emphasize the need of better understanding the role of ECM fungi in the forest restoration practice as it seems crucial for afforestation success and biodiversity rehabilitation. Thus, ectomycorrhizal traits should be a prime consideration in afforestation and carbon sequestration polices, sustainable forest management and biodiversity conservation practices.
