Sažetak
Research of invasive flora of the cities of Dugo selo and Samobor was conducted during the vegetation seasons of 2012 and 2016 on plots measuring 250x250 m2. Altogether, 54 plots were surveyed in Dugo Selo and 109 in Samobor. The comparative analysis of the spatial distribution of invasive taxa during the study period showed that in Dugo Selo the number of new IAS findings has risen by 60, 35%, and in Samobor by 90, 01%. The increase of invasive plants was more expressed in urban parts of the cities, and less in the suburban-rural areas. The largest increase in frequency of occurrence was shown by the species Erigeron annuus (L.) Pers. s.l., Conyza canadensis (L.) Cronquist and Ambrosia artemisiifolia L.: E. annuus has spread in Samobor from 147 locations (within 85 surveyed plots) to 241 locations (within 96 plots), and in Dugo Selo from 44 (28 plots) to 66 locations (94 plots) ; C. canadensis in Samobor expanded from 111 sites (71 plots) to 198 (87 plots), and in Dugo Selo from 29 locations (21 plots) to 60 (54 plots) ; A. artemisiifolia in Samobor expanded from 65 (48 plots) to 134 locations (70 plots), and in Dugo Selo from 26 (25 plots) to 47 locations (33 plots). This was the first organised research of invasive flora in Dugo Selo and Samobor, which has pointed to the need for more intensive monitoring and control of IAS spread in order to mitigate their negative impact in the towns of the Zagreb County.
