Abstract

Maintaining alkaline grasslands in good condition, preserving their yield and diversity is important not only for nature conservation, but also for farming. In our study, we compared the impact of increased number of animals (year 2017) and the low number of animals (year 2015, initial state) and the grazing exclusion on the vegetation of wet alkaline marshes and drier alkaline meadows in the Hortobágy National Park. During the tests, a total of 40 permanent plots were sampled in grasslands grazed by extensive cattle (Hungarian Grey) and mixed genotype intensive cattle, as well as in control (ungrazed) grasslands. We have shown that grazing has a significant effect on species richness. The largest number of species was found in the grazed areas in the 3rd year, the smallest in the control. The undergrasses and legumes cover significantly increased on the intensively grazed grasslands. Grazing had a different effect on each grassland type. On the drier grasslands greater number of species were found, compared to the wet grasslands. Furthermore, it was found that grazing with extensive beef cattle is suitable for the management of dry and wet alkaline habitats. The intensive cattle supports lower species richness in the wet grasslands than the Hungarian grey, but it is suitable for managing dry alkaline grasslands.
