The vegetation of the islet of Badija (south Croatia), with some notes on its flora

Abstract

The vegetation and flora of the south Croatian islet of Badija (0.97 km 2 ), located in the Korčula archipelago, were studied in 2014 and 2015. From a total of 52 phytosociological relevés, 12 floristically and ecologically distinctive vegetation communities were identified and described (eight associations, one subassociation and three stands) within nine vegetation classes. Among them, Teucrio capitatiMarrubietum incani Jasprica et Milović 2016 is described and proposed as a new association, belonging to the Stellarietea mediae class. Altogether, nine NATURA 2000 habitat types were recognized. Regarding the flora, 27 new vascular plant taxa (26 species and one subspecies) were recorded for the islet. Therefore the entire recorded flora of the islet of Badija now consists of 409 vascular plant taxa. Of the newly recorded taxa, four are considered to be invasive. One taxon is strictly protected by law. The Red List categories Least Concern (LC) and Data Deficient (DD) are assigned to one species in each. Vegetacija i flora južnojadranskog otočića Badije (0,97 km 2 ), smještenog u korčulanskom arhipelagu, istraživani su 2014. i 2015. Na temelju 52 fitocenološke snimke određeno je i opisano 12 floristički i ekološki različitih vegetacijskih zajednica (osam asocijacija, jedna subasocijacija i tri sastojine) u okviru devet vegetacijskih razreda. Među njima, asocijacija Teucrio capitati-Marrubietum incani Jasprica et Milović 2016 opisana je i predložena kao nova za znanost, a pripada vegetacijskom razredu Stellarietea mediae. Uvtrđeno je devet NATURA 2000 stanišnih tipova. Determinirano je 27 novih svojti (26 vrste i jedna podvrsta) vaskularnih biljaka za otočić, pa je ukupan broj svojti sada 409. Među novim svojtama, četiri su invazivne, jedna je zakonski strogo zaštićena. Po jedna svojta pripada kategorijama najmanje zabrinjavajućih (LC) i nedovoljno poznatim biljkama (DD).Ključne riječi: fitocenologija, novi sintakson, vaskularne biljke, novi nalazi, Direktiva 92/43/EEZ, istočni Jadran, Sredozemlje INTRODUCTIONFloristic investigations on the island of Korčula have a 160 year tradition (de Visiani, 1842(de Visiani, , 1847(de Visiani, , 1852(de Visiani, , 1872(de Visiani, -1881, while a detailed historical overview of research into the flora of the island has been presented by Trinajstić (1995Trinajstić ( , 2000. According to Jeričević et al. (2014), the total recorded number of plant taxa (species and infraspecific taxa) on the island of Korčula, including neighbouring islets, is 1063. Regarding the vegetation, some studies within the phytosociological scope recognised several plant associations of the three main groups of communities on the island: forest, halophytic and ruderal vegetation (cf. Trinajstić, 1973(cf. Trinajstić, , 1979(cf. Trinajstić, , 1985(cf. Trinajstić, , 1986. However, the level of knowledge on the vegetation of the island of Korčula is minimal, and the current state of the diversity in plant communities in practice remains to be determined.Similarly, the vegetation of all islets in...

Flora of the islets near Pakoštane (Dalmatia, Croatia)

“…flora (Pandža, 2002;Jasprica & Ruščić, 2013;Skelin et al, 2014), indicative of the dry Mediterranean climate. Life form spectra in the flora of the investigated islets do not significantly differ from those recorded for other Dalmatian uninhabited islets (Milović, 2004a;Bogdanović&Mitić, 2003;Jasprica et al, 2006;Pandža et al, 2011;Skelin et al, 2014). …”

Botanical Analysis of the Baroque Art on the Eastern Adriatic Coast, South Croatia

“…Various floras were used to determine the plants according to their diagnostic elements and their ecological and biogeographical aspects (for details, see Jasprica and Milović [31], Milović et al [32], and Jasprica et al [33], as well as references therein). Matthioli [34,35] was also consulted for iconographic analysis.…”

“…Today, the Pelješac peninsula is one of the Important Plant Areas (IPAs) in Croatia and has a high structural diversity of vegetation [25,26]). On the peninsula, there are sites rich in endemic flora [27], while the larger part of the peninsula is covered by the NATURA 2000 network of protected areas in Croatia [28,29].…”
