Abstract

The flora of Stupnik and its surroundings (northwest Croatia).

Abstract

Stupnik is located in northwest Croatia, 10 km southwest of the city of Zagreb, and the researched area includes villages of Gornji Stupnik and Donji Stupnik, as well as smaller parts of the villages Kalinovica and Lučko. The area was floristically researched in the period from 2002 to 2005 during vegetation seasons. A total of 454 taxa of vascular plants from 81 families were found. Of the identified taxa, the most belonged to Poaceae (8.4%), Asteraceae (7.5%), Fabaceae (5.9%), Lamiaceae (5.8%) and Rosaceae (4.7%). In the life form spectrum hemicryptophytes were dominant (225 taxa; 49.6%), therophytes were also numerous (109 taxa; 24.0%), followed by phanerophytes (50 taxa; 10.9%), geophytes (45 taxa; 10.0%), chamaephytes (14 taxa; 3.1%), and hydrophytes (11 taxa; 2.4%). Phytogeographical analysis showed that Euro-Asiatic geoelement (148 taxa; 32.5%) was predominant, followed by cosmopolites (126 taxa; 27.7%), the European (52 taxa; 11.5%), South-European (41 taxa; 9.0%), Circum-Holartic geoelement (33 taxa; 7.3%) and Central-European geoelement (19 taxa; 4.2%). The Mediterranean geoelement encompassed 9 taxa (2.0%), the East European-Pontic four taxa (0.9%), the Atlantic two taxa (0.4%), as well as the Southeast European (0.4%) geoelement. The Illyrian-Balkan geoelement was represented by only one species (0.2%). Neophytes were represented with 17 taxa (3.7%) and most of them are invasive alien species. Four species (Lilium martagon, Alopecurus geniculatus, Carex vesicaria and Glyceria fluitans) belong to VU category according to the Red Book.
