Investigating the revegetated areas above the treeline in South Tyrol/ Italy: the possibility of danger by grazing

15 to 25 years ago in South Tyrol the eroded areas Meran 2000 (municipality of Hafling) and Tanasenberg (municipality of Laas) were revegetated, both of them are former pastoral properties. Mostly bitumen straw seeding was chosen using a mixture of alpine area species. Some of these revegetated areas were temporarily opened to grazing, while 5 to 7 plots (4*4 meters) per area were kept fenced to prevent grazing. The aim of this study is to analyse changes of both the soil and vegetation that are effected by the grazing, by comparing grazed with ungrazed areas.
