Sažetak
Alien, especially invasive alien species (IAS) 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, some species pose a great problem to public health, e.g. the allergenic plant Ambrosia artemisifolia L. Therefore, first efforts on the national level on IAS actions in Croatia have started in 2006, and within them we carried out researches of alien plants of the city of Zagreb. Field-work on inventarisation of plants was carried out in 2007, 2008 and 2009 on five areas across the city (located linear, from the east to the west city border), with about similar surfaces (5 km2). Plants were determined, data was incorporated in the Flora Croatica Database (http://hirc.botanic.hr) and analysed (taxonomically and according to life forms, residence status, origin, invasive status and similarity of localities). A total of 38 alien plants were found on the localities investigated. Taxonomical analysis showed up that those plants belong to 19 families, of which the family Asteraceae (with 14 plants ) is predominated. According to the life form analysis most of the plants are therophytes (42%), while also hemicriptophytes (24%), phanerophytes (18%), geophytes (13%) and chamaephytes (3%) are present. According to the residence status, ten alien plants are archaeophytes and 28 neophytes. Analysis of neophytes showed up that 67% of them originated from Americas, 29% from Asia and 4% from Africa. Most of the neophytes (25 of them) are invasive alien species. Results of the statistical analysis showed up the biggest similarity index for two loacalities at the city border and confirmed our hypothesis that more alien and invasive plants are present at the city border than within the center. All of our data was incorporated within the special part of the Flora Croatica Database (http://hirc.botanic.hr/fcd/InvazivneVrste/), available for public access, with automatic generation of distribution maps of alien plants and could be used by local and national authorities for further actions against IAS.
