Effects of grazing in the conservation zone of the Neusiedlersee-Seewinkel National Park - A statistical analysis of vegetation data from permanent area monitoring

Around the nature conservation valuable steppe landscape of the Seewinkler Puszta with its To preserve the characteristic birdlife and salt vegetation, in 1987 the traditional pasture use in the area of the National Park Neusiedlersee-Seewinkel again recorded. The new grazing was carried out by a long-standing vegetation ecological Monitoring is accompanied. The present study summarizes the results of the Observation period 1995-2011 based on univariate and multivariate analyses. Previously monodominant, nature conservation-problematic species, such as Quecke (Elymus repens) or land-grass (Calamagrostis epigejos) lost much of its cover in the Sample areas. Biodiversity indices showed only in the area of semi-arid grasslands and Significant differences between former vineyards. Feared negative effects grazing on the varnish vegetation could not be confirmed, which Grazing seems more likely to promote the establishment of halophytes. Acta ZooBot Austria 150/151, 2014, 41-62
