The distribution of alien species Geranium sibiricum in Slovakia

The paper presents data on the distribution and spread of the alien vascular plant species Geranium sibiricum in Slovakia. Greater attention should be given to the existing data on its chorology and habitat preferences in the country. Some pertinent records are dispersed in various local literature sources and herbaria. In Slovakia, this alien species was recorded for the first time in 1924, but the significant increase in localities started after 1980. G. sibiricum has been found in 67 localities scattered irregularly throughout the Pannonian and Carpathian phytogeographical regions. It has been noted in a wide range of anthropogenic habitats at low to middle elevations. Recently, it has spread mainly in urban areas in eastern Slovakia and along railway tracks in northern and western Slovakia.
