Ševčíková, Silvie
The main goal of this thesis was to analyze the composition of weed vegetation on the railway. Selected sections of railway lines were Brno Main railway station and its ancillary operations. Observations were made on five different sites, on the embankment, on tracks, in the no used track, on places between rails and buildings. Vegetation was evaluated by using vegetation of fytocenological plots. At each station were carried out three plots. The first evaluation was in July and the second one in September 2013. Monitoring were statistically processed by analysis DCA and CCA. On the selected section of the railway was sighted a total of 49 kinds of plants. The highest ground cover species were Ailanthus altissima, Achlea millefolium, Arctium tomentosum, Arrhenatherum elatius, Digitaria sanguinalis, Echium vulgare, Equisetum arvense, Parthenocissus inserta, Sambucus nigra and Viola arvensis.

The aim of the thesis was to evaluate the species composition of vegetation on the selected section of railway. Selected sections of the railway track near the railway station Brno main railway station and its auxiliary operations. Observations were made at five different sites, on the embankment in the track, the track standstill, between the rails and buildings. Vegetation was evaluated by using vegetation of fytocenological plots. At each station were carried out three plots. The evaluation was three years in the years 2013, 2014 and 2015. All reviews are carried out in the month of July. Following were statistically processed analysis DCA and CCA. On a selected section of the railway was over three years found a total of 51 species of plants. The most frequently occurring species at sites Ailanthus altissima, Arrhenatherum elatius, Digitaria sanguinalis, Echium vulgare, Equisetum arvense, Parthenocissus quiquefilia, Sambucus nigra.
