Follow-up of the cover value of grassland plants with different light demand in different types of grassland
17-21Views:376Changes in the cover value of grassland species over a four-year period were investigated in terms of light requirements for grassland species under different management regimes (mowing, mulching, meadow management, overgrazing). The highest cover values of light-demanding grassland plants (Trifolium sp., Achillea sp., Plantago sp.), which are ecologically and economically valuable and typical for extensive grassland with a soil condition of Solonyec, managed by the MATE Research Institute Karcag, were measured under mowing and meadow utilization. The lowest cover values of light-demanding butterfly-flowering species were found in treatments covered with leafy phytomass and overgrazed with sheep. In the overgrazing treatment, we observed invasive emergence of the light-hungry Hordeum murinum, a potential threat to sheep welfare.

Botanical survey of a permanent buffalo pasture
23-29Views:385A botanical survey of a buffalo pasture of Dunaszeg was carried out on 14 May 2024. The study area was a French buffalo meadow (Arrhenatheretum). The results of the cenological survey were evaluated according to Borhidi's Social Behaviour Types and ecological indicator values (water demand, nitrogen demand, light demand), and the degree of degradation of the area was determined. The dominant plant species in the area was French perennial (Arrhenatherum elatius), classified as a disturbance-tolerant species with 36.09% cover. The degree of degradation of the area is close to 1 (DF: 0.99), indicating the degradation of the area due to the constant grazing every day of the year for the 3rd year. In the study area, reducing grazing pressure and occasionally introducing natural seed dispersal into the grassland management technology could be a solution to regenerating the vegetation.
