The effect of different management on plant diversity and biomass production of grass stands
 JÍLKOVÁ, Lucie
The aim of this study is to assess the effect of different management practises on submontane meadow plant diversity, species richness and biomass production. The experiment was carried out in the submontane region Šumava (Kaplicko, Velký Chuchelec, Údolí Velenovského potoka). There were applied four types of management {--} continual grazing, mulching, fallow (Velký Chuchelec) and mowing (Údolí Velenovského potoka). Plant diverzity and hay production has been observing for three years. Obtained data were used for calculation Simpson and Hill index diverzity, value of fodder quality and nutritive and water regime (condition) of site. Values were used for statistical computing (ANOVA, Fischer LSD test). The plant species diverzity and biomass production are significantly affected by grassland management (treatment). Mulching and fallow lead to lower species richness and increases the coverage of grasses. Hay production is higher on mulching and fallow stands and on mowed stands than on continuously grazed stands. Mowing leads to higher species richness. Is necessary to conserve this status by mowing or the better way is to intesify contemporary management.
