摘要: The Central European flora is an important source pool of plant species introduced to many regions throughout theworld. In this study, we identified a total 759 plant species the Central that are currently recognized as alien species in Australia. We explored temporal patterns of introduction these Australia relation to method introduction, growth form, naturalization status and taxonomy. Across all species, substantially larger numbers of species were between 1840 and 1880 well as between 1980 the present, with small peak of introductions within 1930s. These reflect early immigration Australia, recent improvements fast and efficient transportation around globe, emigration away from difficult conditions brought about by lead up to the Second World War respectively. found majority of had deliberate (69%) rather than accidental (31%) introductions most have not naturalized (66% casual species, 34% species).
