A proposal for updating the list of invasive alien plant species in Bosnia and Herzegovina.

An updated inventory of the invasive flora of Bosnia and Herzegovina is presented. The checklist includes 66 taxa (63 species, one subspecies and two hybrids), distributed between 46 genera and 28 families. The most common family is Compositae (20 taxa; 30.30%) and the most diverse genera are Amaranthus (five taxa) and Erigeron, with four taxa. The predominant life forms are therophytes (54.54%) and hemicryptophytes (22.73%). Most invasive alien plant species are native in the Americas (46) and Asia (14). Most taxa in the invasive alien flora of Bosnia and Herzegovina (43 taxa, 65.15%) have been introduced accidentally, 19 taxa (28.79%) have been introduced deliberately, whereas the remaining four taxa (6.06%) have been introduced in both ways: deliberately and accidentally. Five invasive alien taxa of concern to the European Union have been recorded in Bosnia and Herzegovina. [ABSTRACT FROM AUTHOR]
