The paper deals with the examination results of flora and vegetation of the Melekeska and Shukralinka valleys within Naberezhnye Chelny. The most common plant associations are identified, they are Bromopsetum variograminosum, B. varioherbosum, Festicetum variograminosum, Calamagrostetum epigeiosum; Phragmitetum australis associations are identified in the flooded areas. Anthropogenically altered areas with a high mosaicity of listed above associations communities and ephemeral weeds are widely represented. The volume and structure are shown in the areas flora. This area is subjected to constant anthropogenic load. Taxonomic and geographic analyses of flora as well as a range of vital forms and ecological types are submitted. 120 plant species from 94 genera and 40 families have been identified. The position of the leading families is like that in regional flora, Asteraceae, Poaceae, and Fabaceae are leading. Perennial polycarpic grasses especially long-rhizome (21,7%) and tap-root (15,0%) dominate among biomorphs (69,2%). Species with wide ranges are of paramount importance, they are Euro-West Asian (30,9%), Eurasian (27,5%), Holarctic (11,7%) and the percentage of alien species is 8,5%. Ruderal (36,7%), meadow (17,5%) and humid meadow (11,7%) species are leading in the ecological-coenotic spectrum. The adventive flora is represented by 16 species and it is briefly analyzed. Valley floras of some other Middle Volga rivers have been compared.

Food Value

Meadows and pastures are important resource of livestock feeds in mountain regions and all plant species on them don?t have same value as livestock feeds. From aspect of food value for livestock all species fundamentally can distribute as useful and harmful plants. In paper are represent two plant associations of Stara Planina Mountain Festucetum vallesiacae and Agrostietum vulgarae. In this associations, besides useful plants, are defined, harmful plant species, there present in associations and all of it in aim of ascertainment measures for their removal or reduction from sward. Group of harmful plants is segmented on three subcategory: bed and worthless plants, harmful and poorly poisons and very poisons plants. Association Festucetum vallesiacae count 75 plant species and of that, category bed and worthless plants belong 26 plants or 34.7 g kg-1, category harmful and poorly poisons belong 8 or 10.6 g kg-1, while category very poisons plants default. Association Agrostietum vulgare count 47 plant species and of that category bed and worthless plants belong 17 or 36.17 g kg-1, category harmful and poorly poisons just one plant or 2.13 g kg-1 and category very poisons plants default too.

<p>The species composition of vegetation associated with the Carpathian fens primarily depends on the type of water present and the hydrological feeding of the soils that occur there. These, in turn, shape the fertility of the fens. Those with typically formed <em>Carici-Agrostietum caninae</em> and <em>Valeriano-Caricetum flavae</em> fundamentally differ in the properties of their soils and feeding waters. These include differences in mineral content, pH, CaCO<sub>3</sub> levels, degree of peat decomposition, electrical conductivity and oxygenation of the waters that feed the fens. <em>Carici-Agrostietum caninae</em> is a homogenous plant association adapted to extreme habitat conditions. It is characterized by a very narrow range of essential soil and feeding water parameters. <em>Valeriano-Caricetum flavae</em> is a highly diverse association. Considerable diversity both in terms of plant species and vegetation structure reflects very wide ranges in the properties of soil and feeding water. Vegetation patches of transitory character were also identified. These contained plant species characteristic of both associations. The character of the vegetation depends mainly on fen soil pH and the degree of mineralization of the feeding waters. It is only these parameters that allow intermediate patches to be clearly distinguished. The degree of peat decomposition, mineral content and water oxygenation all differ for <em>Carici-Agrostietum caninae</em> and <em>Valeriano-Caricetum flavae</em>, whereas the values for intermediate patches display a range of parameters typical of both investigated associations. Consequently, vegetation present in these patches reflects to a greater or lesser extent one of the two analyzed plant associations.</p>

During the vegetation seasons in years 2004-2005 the health state of rush plant species from <em>Phragmition</em> and <em>Magnocaricion</em> alliances around the Lake Glinno was investigated. From 13 plant species with disease symptoms 94 species of fungi and FLO were isolated. The highest mycological biodiversity was stated in <em>Phragmitetum australis</em> (24 species) and <em>Thelypteridi-Phragmitetum</em> (27 species) plant associations. The host species in which the biggest number of fungi and FLO species was observed were: <em>Phragmites australis</em> (37 species) and <em>Carex acutiformis</em> (25 species). The highest mycological similarity based on the Jaccard-Sörensen coefficient occurred between <em>Caricetum acutiformis</em> and <em>Glycerietum maximae</em> plant associations (50%) whereas the lowest value of the coefficient represented <em>Glycerietum maximae</em> and <em>Phalaridetum arundinaceae</em> associations (7%).

Abstract The strictly protected Hacquetia epipactis, which natural range has its north-eastern limit in the area of the Cieszyńskie Foothills, is one of the most interesting rarities of Polish flora. For one and a half centuries H. epipactis was popular with scientists resulting in a relatively high number of papers addressing this plant. Usually, however, the characteristics of sites where H. epipactis occurs have been overlooked by the researchers. The aim of this work was to fill this gap, at least partly, by determining plant associations that are preferred by this species. Based on previous phytosociological records and by implementing numerical classification methods, it was found that the Hacquetio-Fraxinetum excelsioris Marinček 1990, which is divided into two subassociations (typicum and allietosum with other variants), is the main association in which this plant species occurs. In isolated sites, mostly outside the Cieszyńskie Foothills, it also appears in fragments of Galio sylvatici-Carpinetum betuli Oberd. 1957 and Tilio cordatae-Carpinetum betuli Tracz. 1962 associations.

This paper presents floristic characterization of xerothermic plant associations and analysis of changes of flora within Broczówka steppe reserve. The floristic research was carried out in 2004-2009. Numerous species that were noted here almost 30 years ago were not found in the present study, the size of other populations decreased. Nevertheless, many plant species occurring in the reserve are rare, endangered or protected. Six major plant associations, impoverished form of two ones and one plant community are distinguished in the whole area of the reserve. Occurrence of two plant associations was not confirmed.
