The experiment of the LFZ Raumberg-Gumpenstein in Styria from 2001 to 2013 directly shows the differences between the four experimental conditions “Use of grassland by suckling cows”, “Use of grassland by sheep”, “Mechanical maintenance by mulching” and “Abandonment of grassland”, concerning conservation of cultural landscape. The experimental site Buchau is situated between Admont and St. Gallen in Styria and lies 870 m above sea level. The suckling cows are rared on 10,80 hectares and the stocking capacity is about 1,13 livestock units (LU) per hectare. Studying the comparison of the cycling of nutrients and nitrate leaching, the Lysimeter experiment at the LFZ Raumberg-Gumpenstein from 2001 to 2009 gives useful information. From this experiment there are data for conditions without keeping animals. In regard to biodiversity within the experiment, the change in species variety was analysed on a 50-m area after nine years. Additionally, the animal performances of 67 bovine animals were collected within the Buchau-Experiment. The thesis shows, that suckling cow husbandry is important for the conservation of cultural landscape as well as the cycling of nutrients, nitrate leaching and conservation of biodiversity.
