The Influence of Grazing on Floristic Composition and Structure of Grassland

Nada Hulina ; Hrvatska

Abstract

As part of research into grassland exploitation system, an investigation testing-ground in Medvednica (30 km north of Zagreb) has been used for determining the influence of rotational grazing of sheep on
botanical composition of grassland.
The rational pasture-ground is located in a beech and fir forest zone (Fagetum croaticum abietetosum Ht) at the altitude of 610—665 m above the sea level. It has been established on a grass-plot which, systematically and typologically, belongs to ass. Arrhenatheretum medioeuropaeum. In addition to rotational grazing, the grass-plot has been regularly fertilized.
After the first year of exploitation, in the floristic composition of the grass-plot there wore already determined all the features of an intensive pasture-ground of Lolio-Cynosuretum Tx. 37 type (characteristic species of ass. Lolio-Cynosuretum and alliance Cynosurion, along with species of classes Plantaginetea, Chenopodietea and Artemisietea).
During the fourth year and later, the plot was subject to heavier grazing, which was reflected in the floristic composition of the pasture- ground. After the sixth year of exploitation, the pasture-ground acquired the features of an extensive pasture-ground, in which indicators of the habitat acidification formed a prominent group of plants, and the dominant species of grasses was Festuca rubra.
