Sažetak
Flora and vegetation of the three small islets: Gospin Škoj (surface area 1.57 ha ; perimeter 527 m ; max. altitude 15 m a.s.l.), Srednjak (1.04 ha ; 374 m ; 8 m a.s.l.) and Goljak (3.31 ha ; 686 m ; 8 m a.s.l.) were intensively studied in 2014 and 2015. This study presents the flora and the vegetation of these islets for the first time, as well as a comparison with islets of a similar size on the eastern Adriatic Sea. Floristic surveys were conducted using the standard method described by Nikolić et al. (1998). Vegetation was studied in accordance with the principles of the Braun-Blanquet approach (Braun-Blanquet 1964). The islets are located in the vicinity of the village of Sreser within the Special Marine Reserve Mali Ston Bay and Malo More, enclosed by the mainland and the Pelješac peninsula in south Croatia. The islets’ coasts are low and rocky. Sea depths around the islets are 2-13 m. Phytogeographically, the islets belong to the steno-Mediterranean vegetation zone of the Oleo sylvestris-Ceratonion siliquae alliance. The floristic data have been used in order to analyze life-form and chorological spectra and to assess species-area relationship, the occurrence of islet specialists and the risk of alien plants invasion. The islets showed a relatively low variety of plant taxa and plant communities. Benthic cormophyte communities in the eulittoral and infralittoral zones are represented by the Nanozosteretum noltii Harmsen 1936 (Zosteretea marinae) and Cymodocetum nodosae Braun-Blanquet 1952 (Halodulo wrigthii-Thalassietea testudinum) associations. The halophytic vegetation of the coastal rocks belongs to the association Limonietum anfracti Ilijanić & S. Hećimović 1982 (Crithmo maritimi-Staticetea). On the islet of Goljak, the Myrto communis-Pistacietum lentisci (Molinier 1954) Rivas-Martínez 1975 association mostly forms the strip between halophytic vegetation and the islet’s central area covered by ca. 2.5 m high macchia with Erica arborea. The Oleo sylvestris-Pistacietum lentisci Braun-Blanquet 1931 association and macchia with Erica arborea cover the most surface areas of the Gospin Škoj and Goljak islets, respectively. Due to the presence of a large population of European rabbit, the ground layer of the dense impenetrable macchia with Erica arborea is extremely poor in species.
