Abstract

Herbarium collections are the most reliable source of historical data available with respect to alien plants. A review of the ZA and ZAHO herbarium collections revealed the presence of as many as 1,152 specimens of invasive alien plant species (IAS), belonging to 70 plant taxa. The extent of sampling invasive taxa was not constant over time; a high 67% of the collection has been collected since the Second World War, with the collection peaking between 1900 and 1920, between 1960 and 1970 and in the years after 2010. Herbarium records of 17 taxa revealed that they first appeared in Croatia much earlier than was known from the literature so far. In order to enhance its public availability, the collection of IAS studied has been digitised and published in the virtual herbarium.
