Map of sample sites in the Czech Republic. Phytogeographic regions, reflecting the climatic conditions, are indicated by three shades of grey. Thermophyticum includes warm areas with a thermophilous flora and vegetation. Mesophyticum harbours flora and vegetation typical of the central European temperate zone. Oreophyticum is a cold region with mountain flora and vegetation corresponding to forests of the boreal zone, with smaller areas above the timberline similar to habitats in the arctic zone (see Kaplan 2012).
