Distribution and habitat suitability maps for Central European steppe plants

<p>This dataset contains distribution maps for Central European steppe plants and coordinates of species occurrence points used by Div&iacute;&scaron;ek et al. (2022) to calibrate habitat suitability models. These models were projected onto past climates and the resulting habitat suitability maps for 10 periods since the Last Glacial Maximum (LGM) are also included. These maps were further used as input data for simulations of species migration from climatically suitable areas in the LGM to identify those that may have served as a source for colonisation of the species&#39; current ranges. For each species, we present maps of climatically suitable areas during the LGM and mid-Holocene (for the latter period, only areas accessible from the LGM are shown), as well as maps of the &quot;source areas&quot; from which the species may have colonised the regions occupied today.</p>
