The climate changes primarily affect the botanical composition of grassland that is subsequently determined by production of above-ground phytomass which is used like feed for the ruminants. In our field experiment we assessed the impact of climate changes on grass ecosystem during the long-term period （23 years）. We obtained a picture of the preceding development of botanical composition in this stand, due to the assumption that expected climate changes are going to disturb the botanical composition of grassland especially in the grass biome. From the obtained results follows the significant change in botanical composition in grass-herbaceous vegetation with the low share of legumes. It is not possible to confirm strict relation between precipitation during vegetation season and the share of individual botanical group. Analysis of long-term development of the botanical composition of monitored grassland influenced by different pratotechnical interventions demonstrated the significant flexibility this plant community in the times of changing climatic conditions.展开更多
