CUT MOWING AND GRAZING EFFECTS WITH GREY CATTLE ON PLANT SPECIES COMPOSITION IN CASE OF PANNON WET GRASSLANDS

Examined area can be found at Balaton Uplands National Park (Hungary). 5 sample areas were examined in Badacsonytordemic: 1: 32 hectare under-grazed pasture, 2: 38 hectare overgrazed pasture, 3: 34 hectare hayfield, 4: trampled area, 5: beaten track. Livestock population was 118 in the monitored pastures. Sampling was executed along five 52m long circular transects, within 5cm x 5cm interlocking quadrates. Based on the data we can state that the curve of the drinking area was the highest of species-area examinations however weed appeared because of degradation which provided more species. According to species-area examinations overgrazed areas were richer in species then other examined areas. Based on diversity data drinking area considered degraded, while meadow and overgrazed areas was considered as proper state. Diversity of meadow was larger, but dominance of economically useful species was smaller. The amount of less valuable species - Carex hirta - increased.
