Native and decorative flora of the island of St. Klement (Pakleni Archipelago)

The island of St. Klement is the biggest island in the middle-dalmatian group of Pakleni archipelago, which lies southwest from the island of Hvar. It is built mostly from Cretaceous limestone and dolomite, therefore the typical morphology of terrain is karst one. According to the climate classification by Koepen the island of St. Klement belongs to the Mediterranean climate with warm to hot, dry summers and cool, wet winters (Csa). The research of the native and decorative flora of the island of St. Klement was carried out during 2007, 2008 and 2009. The total flora is comprised nowdays of 590 taxa from 346 genera and 102 families. Field research confirmed finding 93 taxa and reported 432 new taxa, whereof 168 belonging to native and 264 to decorative flora. The most abundant families in the native flora are Fabaceae (11, 66%), Poaceae (10, 74%) and Asteraceae (5, 83%), while the most abundant ones in the decorative flora are Arecaceae (19, 32%), Agavaceae (16, 67%), Cactaceae (7, 26%) and Zamiaceae (5, 30%). The most abundant life forms in the native flora are therophytes (42, 33%), hemicryptophytes (23, 93%) and geophytes (12, 27%). Dominant plants in the total flora are cultivated and adventive plants (45, 93%), but if only native species are taken into account, the most dominant becomes the Mediterranean chorological element (57, 36%). The decorative flora originates mostly from Mexico (16, 67%), South Africa (14, 39%) and South America (8, 71%). The research recorded 7 endemic taxa, 29 taxa noted in the Red Book of Vascular Flora of Croatia and 38 taxa from IUCN Red list. Moreover, 66 native and 27 foreign wild taxa are protected according to the 2005 Nature Protection Act. For the purpose of comparing the richness of species from the power function model (Arrhenius equation) z-value, as well a alpha-indices of diversity were calculated.
