CROATIAN BOTANICAL STANDARDS FOR IAS PREVENTION AND MONITORING

Alien invasive plants are considered one of the greatest threats to flora biodiversity and its conservation everywhere. As a result of this global problem the number of studies dealing with plant invasions is increasing, which is also causing increased confusion about terminology used. As we started with national project about invasive Croatian flora at the beginning of 2006, we prepared a proposal for national standard and criteria, as well as terminology, for both autochthonous and allochthonous flora treatment. This proposal includes regular terminology globally accepted in most botanical communities, but it is particularly harmonized with European standards for alien flora treatment. Special attention was paid to defining the criteria for status of plant species potentially invasive in Croatia, such as origin, residence and invasion status. Croatian botanical community has for centuries collected diverse botanical data (distribution, taxonomy, vegetation, biology, etc.) and in recent times Flora Croatica Database (http://hirc.botanic.hr/fcd/search.aspx) was developed as a taxonomic frame for all floristic researches and mapping standards. As the most of historical data for invasive species are available or will be very soon, thanks to mentioned Database and its possibilities, we produced preliminary list of invasive alien plant species in Croatia, as well as first distribution maps for some of them. This invasive alien plant species inventory is our first step in preparation for prevention, as well as monitoring of IAS already present in flora of Croatia.
