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 conservationally valuable steppe landscape of the Seewinkler Puszta with its to be able to preserve characteristic birdlife and salt vegetation, in 1987 the traditional pasture use in the area of the Neusiedlersee-Seewinkel National Park again recorded. The new grazing was created by a long-standing vegetation ecology. Monitoring accompanied. This study summarises the results of the 19952011 observation period based on uni- and multivariate analyses. Previously monodominant, conservationally problematic species, such as Quecke (Elymus) repens) or land-riding grass (Calamagrostis epigejos) lost heavily in cover in the Test surfaces. Biodiversity indices showed only in the area of semi-dry grass and former vineyard fallows have significant differences. Feared negative effects the grazing on the coating vegetation could not be confirmed that Grazing seems to encourage the establishment of halophytes. ACTA ZooBot Austria 150/151, 2014, 41-62
