Evaluating test fields planted with different sowing methods and surrounding revegetated areas above the timberline
Abstract
General: In the past patches of erosion above the timberline were revegetated mainly by the bitumen straw seeding method. This highly effective method is complex and expensive, so that practical alternatives are required. Methodology: In 1996-1999, 10 to 24 test lots were prepared in the Meran 2000 erosion area and Pfannhorn (South Tyrol), which are now investigated for their effectiveness and potential applications. Preliminary results show that mulch seeding with hay or straw as a protective cover greatly encourages the growth of grass and herbs and offers excellent protection against erosion already in the early stages. At windy spots, adhesives or jute meshes are required to improve cohesion of the mulch layer. Vegetation analyses investigate the canopy density and combination of species in a fenced area to study the consequences of temporary grazing by cattle, looking in particular at differences between grazed and ungrazed pastures. These investigations are carried out in the erosion area of the Tanaserberg in South Tyrol. Objective: Investigating the effectiveness of revegetation methodsInvestigating the change in vegetation by grazing.
