Floristic researches of the island of Pašman, Croatia

The island of Pašman belongs to the archipelago of Zadar in northern Dalmatia. From 2010 to 2012 the vascular flora of the island of Pašman has been studied. It have been recorded 745 species and 629 of them occurs naturally or are spontaneously spread from culture (556 species and 73 subspecies of 366 genera and 94 families). The rest of 116 species occurs only in cultures. From 745 species, 27 were previously recorded, while 718 are stated for the first time in these studies. The most abundant families are Fabaceae (12.72%), Poaceae (11.13%), Asteraceae (6.84%) and Cichoriaceae (6.04%). In the spectrum of life forms the most abundant are Therophytes (45.47%) followed by Hemikryptophytes (25.12%) as expected. The analysis of floral elements shows the highest share of Mediterranean plants (41.02%). There is a significant number of Southern European plants (17.33%) and widespread plants (15.74%). In the Mediterranean floral element the most common are the general Mediterranean plants (26.71%), but particularly important are the Illyrian-Adriatic plants (16 species, 2.55%). In the flora of the island of Pašman 15 species are red listed. Lathyrus ochrus is critically endangered, five of them are endangered: Carex extensa, Delphinium peregrinum, Glaucium flavum, Hibiscus trionum and Ophrys apifera, and nine of them have the status of vulnerable species. Of special value is rich orchid flora, which mainly found on open and sun-exposed habitats such as rocky grasslands and pastures, sparse garrigues and maintained olive orchards. The results show that the island of Pašman has a rich and diverse flora which can be interpreted as a result of its specific phytogeographic position and long-term, but extensive human impact.
