This paper presents the results of grassland biodiversity evaluation of Ivančinské lúky - Meadows which belongs to the Ramsar locality Turiec Wetlands. During growing periods in 2005 and 2006 a botanical analyses of meadow was performed at 19 representative sites. Altogether 107 vascular plant species were identified at the analysed meadows though individual sites have lower number of species (7-16). Shanons index of meadows diversity and index of evenness ranged from 1.08 to 2.58 and from 0.56 to 0.95 respectively. The lowest number of species was observed in meadows of the western part (7-11 species) and the highest in the meadows of eastern part of the municipality (14-16 species). Diversification of plant communities along gradients of numerous environmental factors (light intensity, sunlight regime of plants, requirements for soil nitrogen, soil moisture and pH, altitude, inclination, soil depth) was analysed by methods of direct gradient analysis (CCA) The diversity of meadows was significantly influenced by soil nitrogen and soil moisture. The paper suggests appropriate systems of meadow management focused on conservation and protection of biodiversity.
