During 2017, the indigenous flora of the Bregana settlement in northwestern Croatia was studied. The floristic data available for this area, covering 2.8 km², are sparse, and this study recorded a total of 232 taxa of vascular flora from 178 genera and 75 families. The most common plants belong to the family Asteraceae s.l. (14.4%), Lamiaceae (7.5%), Fabaceae (7.5%), Ranunculaceae (5.1%), Rosaceae (4.6%) and Poaceae (4.6%). The ratio of floristic elements places the study area in the Euro-Siberian/North American region, in the zone of the Central European deciduous forests, with the presence of numerous southern, thermophilic elements, while the species of the Illyrian-Balkan elements indicate a long continuity of those forests, and gives a local distinctiveness to the flora. The presence of Mediterranean, Eastern European and Eastern European/Pontian elements indicates the long-lasting anthropogenic influences. In the spectrum of life forms, the hemicryptophytes are dominant (53%), followed by the phanerophytes and geophytes (15.1%) and therophytes (11.6%). In terms of the IUCN categories of threat, one species is classified as endangered, one as vulnerable, six as near threatened and two as least concern. A total of 29 alien species were also identified, and of these ten are considered invasive. |
