    Opis:
    This study provides original data on the impact of human activity on vegetation under the specific conditions of the Kastanozem from the Kostanay region (northern Kazakhstan). Radical changes in land use are provoking deposition in vegetation. The question remains whether natural vegetation will return or whether a different type of vegetation will be created under the specific conditions of the Kastanozems soils. The evaluation of vegetation took place in the fields that were abandoned in different time horizons. Height, cover, biomass weight and species composition of vegetation were monitored. The vegetation of abandoned fields is characterized by low species diversity. Succession runs from annual species to a stage where perennial dicotyledonous species with a deep root system dominate. Spontaneous vegetation leaves a sufficient amount of biomass on the soil surface, which assumes that the land will be protected from undesirable phenomena such as erosion and desertification processes.

    Opis:
    A floristic inventory of segetal flora was carried out in abandoned fields and adjacent crop fields on rendzina soils in the Zamość region in the year 2010. This study found a total of 130 weed species belonging to 30 botanical families. The following families were represented most frequently: Asteraceae, Fabaceae, Poaceae, Lamiaceae, Scrophulariaceae, and Brassicaceae. In the segetal flora, apophytes are dominant (55% of the total flora), with the highest number of meadow and xerothermic grassland species among them. Archeophytes (38%) predominate in the group of anthropophytes. The species characterized by the highest constancy classes and reaching the highest cover indices posed the greatest threat to crops in the study area. The following weeds are most frequently found in fallow fields: Consolida regalis, Cichorium intybus, and Sinapis arvensis, while Papaver rhoeas is the greatest threat to cereal crops grown on rendzina soils.
    We florze segetalnej gleb rędzinowych Zamojszczyzny zanotowano łącznie 130 gatunków chwastów, należących do 30 rodzin botanicznych. Do najczęściej reprezentowanych rodzin należały: Asteraceae, Fabaceae, Poaceae, Lamiaceae, Scrophulariaceae i Brassicaceae. We florze segetalnej przeważają apofity (55% ogółu flory), wśród których najwięcej jest gatunków łąkowych i muraw kserotermicznych. W grupie antropofitów dominują archeofity (38%). Największe zagrożenie dla upraw badanego terenu stanowiły gatunki charakteryzujące się najwyższymi stopniami stałości i osiągające najwyższe współczynniki pokrycia. Najczęściej występującymi chwastami na odłogach są Taraxacum officinale, Daucus carota, Melilotus officinalis, Elymus repens, Campanula rapunculoides, Papaver rhoeas, Consolida regalis, Medicago lupulina, Matricaria maritima subsp. inodora. Uprawom zbóż na rędzinach najbardziej zagrażały: Papaver rhoeas, Consolida regalis, Convolvulus arvensis, Galium aparine. Zarówno w uprawach zbóż jak i na odłogach najczęściej występuje Papaver rhoeas.

    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:
    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:
    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.
