Bauer, Norbert: Open sandy grasslands of the Bakony region

it was not so earlier - on the fairly dry lime sandy steppes, e.g. the pasture of "Mennydörgő-hegy", "Közlegelő", which were more remote from forests and were grazed moderately. The reason for this can be found in the microclimate, which is drier and more extreme than in the areas not covered with forests, in the presence of grove-like forests of Pinus sylvestris and in the unfavourable water regime of the sandy soil barely covered with vegetation. The Atlantic climatic effects cannot reFig. 3. Principal component analysis of the samples (based on presence-absence matrix).
