This paper evaluates the influence of the use of methods of Molinia meadows in eastern Poland on changes in its biodiversity and species composition. Research was carried out in 2006-10 on Molinia meadows near Uściwierz lake, located in the Pojezierze Łęczyńsko-Włodawskie (Lake District). The studied complex was classified to [Selino carvifoliae-Molinietum] meadows. Meadows were used in a specific method: 1. 1-cut meadow (June), 2. 1-cut meadow (June) + grazing (August), 3. abandoned meadow (since 2000). The above-mentioned methods of use caused the transformation of the typical structure of Selino-Molinietum meadow. I observed the initial succession of forest associations with a large share of Salix rosmarinifolia and Betula pubescens on unused meadow. The highest share of the characteristic species of the Selino-Molinietum association was characterized by abandoned meadow.

Long-lived clonal plants provide an optimal place for the natural storage of seeds as a ‘non-soil seed bank’. We tested the hypothesis that the size and species diversity of a non-soil seed bank deposited within the clonal plant Carex cespitosa depends mainly on the plant's size. To verify this hypothesis, an experiment was conducted on an unmown meadow in the Białowieża National Park. The emerging seedlings of different species originating from C. cespitosa tussocks of different size (large and small) were observed under greenhouse conditions for four years. The size of a non-soil seed bank was evaluated based on the number of seedlings. Significant differences in the seedling number were found between large and small sedge tussocks (Mann-Whitney test Z = 3.96, P < 0.001). However, the number of recorded species was independent of tussock size. Both types of tussocks were dominated by meadow, forest and swamp species (in decreasing order). Some of these species are no longer present in the studied area, or their occurrence is limited to small groups at the meadow's edges. A non-soil seed bank within the tussock cores of C. cespitosamay be, similar to a soil seed bank, a tool for studying the changes occurring in plant communities.

This paper presents the process and results of the implementation of the irrigation system on meadows in Tanzania. The irrigation system was im- plemented in 2010 and 2012 as an element of two development projects co-financed by Ministry of Foreign Affairs of the Republic of Poland un- der the Polish Development Programme. During the first phase ( 2010) the earth water reservoir and the canal carrying water on a meadow were built and the irrigation system based on Amirite sprinklers was installed . In 2012, the concrete water tanks were built , and two hose reel irrigators were bought and put in action . The i mplementation of the irrigation system allowed for a significant increase in the production of hay. In the analyzed time period (from 2008 to 2012) the increase in yields of hay from 34.7 tons to 237.3 tons was noticed. The resulting implementation of the irrigation project increase hay production should be considered valuable, especially under the conditions of advancing climate change and its potential impact on the reduction of agricultural production in Tanzania.

The vascular flora in the “Łąki w Komborni” Natura 2000 site comprises 219 species representing 44 families and 147 genera. Species from the families Asteraceae, Poaceae, Lamiaceae, Fabaceae, Rosaceae, Polygonaceae, Cyperaceae, Apiaceae, and Ranunculaceae were found to dominate. A geographical and historical analysis of species confirmed the clear dominance of apophytes (84%) over anthropophytes (16%) as well as perennials (69%) over short-lived (23%) species. The biological spectrum was dominated by hemicryptophytes (54%) and therophytes (19%), compared with other life forms. In terms of synecology, the flora was mainly represented by species from the classes Molinio-Arrhenatheretea, Stellarietea mediae, Artemisietea vulgaris and Phragmitetea. The “Łąki w Komborni” site is a habitat for 82 (37%) medicinal species and 155 (70%) forage species for bees. Noteworthy is the occurrence of protected species, e.g. Gladiolus imbricatus, Trollius europaeus, Centhaurium erythraea, Dactylorhiza majalis, Platanthera bifolia and Primula elatior.

The effect of modified pratotechnology on herbage production of meadow sward was observed since 2001. Treatments were: mown once (1C) and twice a year with biomass removal — fertilized (2C + N) and unfertilized (2C), mulched twice (2M) and once a year (1M) and non- used plots (0). The yields of aboveground phytomass in 2001 and 2002 were highest on fertilized twice mown treatment {8.7 and 10.4 t DM/ha resp.), on unfertilized twice mown treatment (7.7 and 8.8 t DM/ha resp,). With lower management intensity herbage yield decreased, except in the non-use treatment (6.2 t DM/ha in 2002). The enhancement of yield from nitrogen released from mulch was not found. Vertical stratification of green mass is affected by botanical composition and different treatments.

In the present study soil-water coefficients ksi were determined and evaluation of the influence of soil sucking pressure on the actual yield was carried out. Relations between these coefficients and soil sucking pressure in the root zone are used for the calculation of actual evapotranspiration or actual yield neglecting evaluation of the influence of evapotranspiration on yield.

The phytosociological database as a tool for synthetic and comprehensive study of semi-natural meadows in the Polish part of the Carpathians is presented. It has been developed in the Institute of Nature Conservation of the Polish Academy of Sciences since 2007. All accessible phytosociological relevés were digitalized and stored in a TURBOVEG database. As of January 2013, 4620 relevés have been collected in the database, chiefly from mesic meadows of Arrhenatherion alliance (76%) and mat-grass swards of Nardo-Callunetea class (18%). They were recorded between 1923 and 2012 at an altitude range of 195–2000 m above sea level. For improving territorial coverage of the region by vegetation sampling, since 2009 an extensive field survey has been carried out to collect data from previously unexplored areas and record the actual stage of semi-natural grasslands. As a result 1146 recent unpublished relevés were collected. The statistics of available resources, discussion on the data quality and the application prospects of the database are outlined. The database “Grasslands in the Polish Carpathians” is an intrinsic part of the research on the diversity of vegetation in the Polish Carpathian grasslands, as well as a record of the changes it undergoes.
