    Opis:
    The aim of the study was to evaluate the utility as well as visual and functional characteristics of intensively exploited football pitch, with consideration of the impact of used pratotechnics. In the assessment of the football turf fundamental traits according to the COBORU methodology, in the tested multi-year period the best results were obtained during the spring measurements. Overall aspect of turf as well as sodding level was defined as a good to very good. Turf color was natural between light green, and bluish, however the color of turf on the playing field, was not monochromatic. The turfgrass was characterized by a very low susceptibility to diseases. The range of the grasses root system of in different parts of the field remained at a low level. The grass tillering proceeded best during the spring.

    Opis:
    River valleys are areas of transition between aquatic and terrestrial communities, with complex biological structure. As ecotones they have high biodiversity as a result of the occurrence of species with different requirements according to soil moisture. They create ecological corridors, allowing migration of the organisms in human disturbed landscape. With these migration routes, species of foreign origin which spread to a new area also benefit. Numerous alien species are considered as invasive, and described as a threat to biodiversity due to strong competitive abilities. To describe the relationships between a number of invasive species, biodiversity and size of a river, the vegetation of 750 m fragments of the Odra and Dobra river valleys on the area of the Wrocław city were analysed. The comparison of plant communities in the valley of a large, managed river (Odra) and its small tributary (Dobra) was carried out. The plant assemblages, occurring in study areas, determined the habitat conditions on the basis of Ellenberg’s indicator values (EIV’s), as well as Shannon-Wiener biodiversity index was defined. The designed sites differed according to Shannon-Wiener biodiversity index, as well as soil properties: moisture, reaction, and fertility. In the study side of the Odra river ruderal and scrub species were dominated, whereas in case of study site of the Dobra river – meadows and ruderal species. The invasive plant species occurring in the Odra valley are: Symphoricarpos albus, Solidago gigantea, S. canadensis, Robinia pseudoacacia, Clematis vitalba, Quercus rubra, Reynoutria japonica, Parthenocissus inserta and Echinocystis lobata, and in the Dobra valley: Solidago gigantea, S. canadensis. The analysis of correlation between Shannon-Wiener biodiversity index and share of invasive species revealed statistically significant influence of occurrence of invasive species on biodiversity of plant communities in case of the Odra river.

    Opis:
    The paper presents the first syntaxonomic classification for juniper wood communities in Tajikistan with some remarks on their environmental gradients. A total of 119 relevés were sampled between 2015 and 2021 using the seven-degree Braun-Blanquet cover-abundance scale. They were classified by a modified TWINSPAN method. Diagnostic species were identified using phi coefficient as a fidelity measure. Detrended Correspondence Analysis (DCA) was used to determine relationships between samples, vegetation units and major gradients in species composition. Plant communities have been divided into two main groups. The first one is a west Irano-Turanian wood of Juniperus polycarpos var. seravschanica of the Pamir-Alai mountane belt. It occurs in two variants depending mainly on the aspect and precipitation. The second juniper wood type in Tajikistan is a stand of Juniperus pseudosabina. It prefers the northern slopes and north-eastern ranges of the Pamir-Alai and slightly lower elevations. Both juniper wood types are highly distinct in terms of species composition, especially in the moss layer, and have therefore been assigned to different classes: Pino-Juniperetea (Juniperetum seravschanicae) and Juniperetea pseudosabinae (Carici turkestanicae-Juniperetum pseudosabinae). The main factors determining the species composition of the studied associations are latitude, growing season precipitation, annual range of air temperature and precipitation of coldest quarter. Our study has shown that there are two very distinct vegetation types of the juniper wood groves in Tajikistan, which reflect the main phytogeographical division between the provinces of Turkestan and Central Asia.

    Opis:
    In this paper we present the first syntaxonomic classification for the thermophilous open wood and scrub vegetation in Tajikistan with some remarks on its environmental gradients. Altogether 143 relevés were sampled between 2014–2021 using the seven-degree cover-abundance scale of Braun-Blanquet. They were classified by the modified TWINSPAN method with the use of the four step interval scale with cutoff levels of 0%, 2%, 5% and 10% and total inertia as a measure of cluster heterogeneity. Diagnostic species were identified using the phi coefficient as a fidelity measure. Detrended Correspondence Analysis was used to determine the relation between samples, vegetation units and the major gradients in species composition. Plant communities have been divided into three main groups: (1) dry scrub on screes, (2) mesophilous scrubs in nemoral zone, and (3) open woods. A new class of Pistacietea khinjuki-verae has been proposed for open woods. Further classification of vegetation data resulted in the distinction of four plant communities within two provisional alliances: Roseion kokanicae and Ranunculo tenuilobi-Cotoneasterion hissaricae (communities of Rosa kokanica and R. ecae, associations of Aveno ludovicianae-Rhuidetum coriariae and Calophacetum grandiflorae). Additionally, we established the Pistacion verae alliance for the pistachio groves of Middle Asia with two subassociations: Pistacietum verae typicum and Pistacietum verae cercidetosum griffithii. The main factors determining the species composition of the studied communities are: elevation, temperature, precipitation, slope and aspect. Our research showed that the Pistacia groves are a distinct vegetation typical of the Irano-Turanian area and that further surveys are needed to present a final classification of scrub vegetation of Tajikistan.

    Opis:
    The paper presents research results which aimed at evaluation of the change in the sodding degree and selected strength parameters of sod used with varied intensity; additionally sod was modified through administration of biopreparation. Measurements were taken on two types of sod. The first one was formed from perennial rye grass, the second one from orchard grass. It was proved that the use of the investigated facilities resulted in reduction of sodding, which was related to the sod forming species. No impact of biopreparation use on the sodding degree was proved. Intensive use affected the increase of the value of the analysed strength parameters; at low soil moisture (5.0-5.5%) considerable compaction in the surface layer of soil was reported.
    W pracy przedstawiono wyniki badań, których celem była ocena zmian stopnia zadarnienia oraz wybranych parametrów wytrzymałościowych darni użytkowanej z różną intensywnością, dodatkowo darń modyfikowano poprzez podanie biopreparatu. Pomiary wykonano na dwóch rodzajach darni, z których pierwsza darń utworzona była z życicy trwałej, druga z kupkówki pospolitej. Wykazano, że użytkowanie badanych obiektów skutkowało spadkiem ich zadarnienia, które było ściśle związane z gatunkiem tworzącym darń. Nie wykazano wpływu stosowania biopreparatu na stopień zadarnienia. Intensywne użytkowanie wpływało na zwiększenie wartości analizowanych parametrów wytrzymałościowych, przy niskiej wilgotności gleby (5,0-5,5%) zauważono znaczne zagęszczenie w wierzchniej warstwie gleby.
