Invasive alien plants in Croatia - Case study in the City of Zagreb (Croatia)

Invasive species are nowadays recognized as the second most important cause of biodiversity loss, just after direct habitat destruction. Besides from the conservation point of view, invasive alien plants have a strong negative environmental and economic impact. In addition to that, some species pose a great problem to public health (e. g. allergenic plant Ambrosia artemisifolia L.). According to «Inventory & Monitoring Protocol – Invasive Alien Plants» (IMAP Programme) we started with preliminary plant IAS actions in Croatia and prepared (first Survey Level): a) national criteria and standards for terminology and categories for alien flora (harmonized with European as well as global standards for alien flora treatment) and b) preliminary list of invasive alien plants for Croatia. This should be a good basis in preparation of all next actions against IAS in Croatia, e.g. monitoring and prevention. As there is no ogranised efforts in IAS monitoring on a national level, we have started with case studies of invasive alien plants throughout particular parts of Croatia, both continental and mediterranean. Here we will present preliminary plant IAS inventory for the the biggest and capital city of Croatia – city of Zagreb (continental part of Croatia). For those plants data are incorporated within the special part of the Flora Croatica Database (http://hirc.botanic.hr/fcd/InvazivneVrste/Sear ch.aspx) and are available as standard taxon sheet for each taxon with automatic generation of distribution maps. Here we will represent the most important and/or most widely distributed taxa. Such monitoring is actually a part of the second Survey Level (Reconnaissance) recommended by IMAP Programme and could be used by local and national Authorities for further actions against IAS.
