Phytogeography of the sandstone areas in the Bohemian Cretaceous Basin (Czech Republic/Germany/Poland)

<p>The natural conditions of the individual sandstone regions of the Bohemian Cretaceous Basin are characterized focusing on flora and vegetation. For this survey, regions are geographically defined using the phytogeographic division of the Czech Republic; the parts of sandstone regions extended to Poland and Germany have been also included. <br>In the description of flora and vegetation, the volcanic patches were intentionally omitted because they are an independent source of biodiversity that barely interacts with the surrounding landscape. The given phytogeographical characteristics (sub-oceanic, sub-montane species, etc.) should be understood in the context of the Central European conditions, rather than absolutely. Plant communities are summarized in the appendix.</p>
