Abstract

Invasive plant species are alien, intentionally or unintentionally introduced plants into the territory of the Republic of Croatia. According to International Union for Conservation of Nature, they are the second main cause of native species endangerment and they negatively affect biodiversity. About 614 nonnative species have been registered in Croatia, of which 70 are invasive. Along the Sava River, east of Slavonski Brod, there are 1500 ha of floodplain area, of which about 280 ha is the typical Slavonian floodplain pasture Gajna. The Brod Ecological Society submitted a request, and Gajna received on 14/9/1990 the status of a significant landscape by the decision of the Municipal Assembly of Slavonski Brod. The rich and diverse flora of this area also includes allochthonous invasive plants. The aim of the paper was to analyse invasive flora during the vegetation season of 2019, by determining the ways of their spread and suggesting the possibilities of their control. Identified invasive species were: common ragweed, false indigo bush, common milkweed, horseweed, daisy fleabane, Persian speedwell, and common cocklebur. By taruping and grazing by Podolian cattle, it was possible to control false indigo bush. This weed was, a significant problem until a few years ago. Nowadays natural flora has begun to grow and develop – which was not possible until then. Currently, common cocklebur is widespread, with easily dispersible fruits over Gajna. Since this is an alluvial pasture, seeds could be easily spread further by water.
