The paper presents the floristic changes in species composition of meadow sward after five years when the meadows were desisted from management (cutting). The meadows are situated on hydrogenic soils in proglacial stream Valley of Vistula River and they belong to landscape reservation "Ursynów Slope". In 1998 before the first cut vegetation patches were separated according to floristic aspects. Then samples of vegetation (from 1 m² ) were taken from cach patch; number of samples depended on floristic diversity and ranged from 1 to 4. Floristic types were determined basing on the dominant species with the share above 30% of mass. In 2003 the samples of vegetation were taken from the same places and using the same methods like in 1998. The floristic changes in species composition of meadow sward after desistance from management for five years resulted in: decrcasing in the total number of species - from 78 (1998) to 66 (2003); disappeared mainly the species from dicotyledons (8 species), among them very low species and ephemeral weeds, decrcasing in the number of floristic types - from 16 (1998) to 9 (2003), increasing in the sward of poor quality grasses such as Deschampsia caespitosa and Holcus lanatus. Those species became dominant in three of floristic types and their share exceeds more than 30% in the majority of meadow sward, increasing in the share of high grass species and decreasing in the share of low grass species, the great increase in the share of sedges, rushes and horsetails in 2003, the great decrease in the share of dicotylcdons (weeds and herbs) in cach floristic type, invasion and expansion of weeds of areable lands, later development of trees and shrubs and increasing in the share of forest species in the meadow sward. Preservation of existing biodiversity is possible only in case of introduction of active preservation using extensive form of management.

In the 50-ty years was performed the regulation of the Łabuńka river and detailed ameliorations in the swampy valley poorly available for agriculture. The majority of meadows was ploved and sown by standard mixtures, prevailed by Alopecurus pratensis for more humid soils and Arrhenatherum elatius for drier ones. During 60-ty years the effects of and amelioration were estimated. Found was that in only several years after an amelioration the swamps processes start to dislodge peat processes, whereas the species composition of meadows undergoes disadvantageous changes in undesirable direction for agriculture. More general data regarding to plant cover of meadows from that period and composition of sown mixtures stated the start point for actual study of meadows complexes. An aim of the phytosociological researches, concluded in years 1987-1988 and again in 1997 was paying an attention on the transformations on the plant cover of meadows in many years after finishing of an amelioration. In general the succession progresses from the Molinio-Arrhenatheretea communities introduced to the meadows during their after amelioration cultivation to the communities of Phragmitetea and Scheuchzerio-Caricetea fuscae classes. Contemporary meadow communities were differentiated by the humidity of habitats, fertilization or its lack and utilization or its abandonment.

Floristic and ornithological studies were carried out primarily in years 2002 and 2003 in the region of southern Wielkopolska within the confines of the Przygodzice Fish Pond complex. The complex covers the area of several hundred hectares of which a considerable part is taken up by fishponds, while the remaining area is occupied by forests and grass communities - both meadows and rushes. The Przygodzice Fish Ponds constitute a well-known and important ornitho-fauna shelter of European importance. The goal of the investigations was to ascertain the role of meadow communities and their plant cover in the quantitative and qualitative development of both breeding and migrant birds of the discussed region. The analysis of the list of bird species identified in the entire complex of the Przygodzice Fish Ponds in the years 1998-2001, which was prepared on the basis of our own research as well as studies conducted by other authors revealed that 61% of the entire ornitho-fauna of this area is closely linked, at various stages of their biology, with grass communities, mainly with meadows, and 35% of these birds are breeding species native of these communities. Detailed quantitative investigations on the bird populations were carried out within the framework of this study on two 70 ha arcas, marked off from two meadow complexes differing with regard to the intensity of their utilisalion and plant cover. The breeding ornitho-fauna of the examined complexes turned out quite similar with regard to the number of species but differed regarding their quality. Such bird species as: Crex crex, Gallinago gallinago, Saxicola torquata, Locustella naevia, Emberiza schoeniclus preferred meadows of distinctly mosaic plant cover dominated by rush plants and such grasses as: Phalaris arundinacea, Phragmites australis or Glyceria maxima, which had not been utilised for several years or utilised irregularly with neglected drainage ditches. On the other hand, such species as: Coturnix coturnix, Vanellus vanellus, Tringa totanus or Saxicola rubetra nested exclusively or in large quantities on meadows, which were utilised regularly with sward where pasture grasses prevailed. These meadows also turned out to be more attractive for migrating birds. The unqueslionable ornithological value of the Przygodzice Fish Pond complex depends, to a considerable extent, on the presence within its confines of meadows of various degrees of utilisalion and diversified plant cover. Their reduced utilisation, even to total abandonment, may lead to the quantitative and quatitative impoverishment of the ornitho-fauna of this region.

The studies were carried out in 1990-2001 in central Poland on a natural moderately wet meadow site. The objects were two fenologically different meadow mixtures: mid-late and late. The aim or the study was to evaluate the changes of botanical composition of these mixtures in yields during 12-year ulilization. The annual yields of mixtures were rather similar but differed significantly in the years of utilization. It was affected by meteorological conditions. The share of grass species and their cultivars in the mixtures differed from the structure established at sowing. It was determined first of all by competition between components of mixtures and the weather conditions. The most persistent and aggressive component of investigated meadow mixtures was Dactylis glomerata epecially cultivar 'Nera'. Poa pratensis cultivar 'Beata' and Festuca rubra cultivar 'Brudzyńska' were less persistant components than Dactylis glomerata. Cultivars of Lolium perenne maintained in sward for three years but cultivars of Festuca pratensis and Phleum. Pratense only for two years of ulilisation. Trifolium pratense cultivar 'Parka' appeared to be unstable and retreated after two years from the sward.
