It has been updated by incorporating new data collected over the last decade and reassessing the current status of taxa based on improved taxonomic and ecological knowledge. All changes in taxon listing from the 2012 version are documented and explained in an appendix. Based on comprehensive data sources, including the recently developed Pladias database of the Czech flora and vegetation and the Archaeobotanical Database of the Czech Republic, we list 1576 taxa alien to this country, with information on their taxonomic position, life form, geographic origin, residence time status (archaeophyte or neophyte), invasion status (casual, naturalized or invasive), date of the first and last field record, grid-cell occupancy, pathway of introduction into the country, habitat affiliation and impact assessment. This edition includes 122 more taxa than the 2012 edition; 157 taxa were added and 35 were removed; 17 taxa were reclassified as native, eight were removed due to lack of evidence, records of six taxa were assessed as doubtful, and four are not taxonomically justified. The alien flora is recruited from 630 genera and 122 families and comprises 385 archaeophytes and 1191 neophytes; most taxa are casual (1084, i.e. 68.8% of the total number), 417 taxa are naturalized (26.4%), and 75 are invasive (4.8%). The proportion of invasive taxa is almost ...
