Sažetak
The aim of our research was to test the susceptibility of maintained urban areas to the spread of invasive alien plants. A case study was conducted in the small town of Dugo Selo in Zagreb County, where weed maintenance and removal measures are regularly implemented. Field researches were carried out during 2012 and 2016, during which 54 plots (250x250 m2) were explored on an area of about 3.38 km2. We recorded a total of 34 (in 2012), and 36 (in 2016) invasive plants, respectively. All observed invasive plants belong to 18 families, of which the most represented are Asteraceae (13 taxa). The most invasive taxa originate from the Americas (65.45%), and the spectrum of life forms is dominated by therophytes (60.18%). Majority of invasive plants show competitive - ruderal (44.00%) and competitive (37.45%) life strategies, and 42.36% of them apply a strategy of more propagation methods. Most invasive plants have been recorded in the habitat: residential houses in a row with back gardens, individual houses (29, 33%). During the repeated research in 2016, the increase in the number of invasive plants does not seem large, but it is worrying that a significant increase in the number of their findings was observed on all plots (increase from 343 findings in 2012 to 550 in 2016). This is especially true for the most common, unintentionally introduced weeds Ambrosia artemisiifolia, Conyza canadensis and Erigeron annuus, which is a cause for concern due to their huge potential for expansion into new areas. All this indicates the need for even more intensive and organized monitoring and management of invasive alien plants in urban areas, in particular weeds, in order to prevent their spread, especially to native areas.
