History of studies and biogeographic peculiarities of islands Prvić, Grgur and Goli

Prvić, Goli and St. Grgur are the most stormy and the largest uninhabited Adriatic islads. Recently they were geologically studied, but their biology was almost unknown. The richest flora of 351 species (16 endemics) is in Prvić, and 307 in Goli, 193 in St. Grgur, but only 2 - 14 halophytes in adjacent islets. From 1967 we have studied 114 permanent marked stations in Prvić, 42 in St. Grgur, 21 in Goli from 1974, and 8 in minute islets with halophytes only. In their zoning predominates the evergreen eumediterranean, but the upper ridge of Prvić (363m) is supramediterranean with Ostrya, Festucion illyricae and Seslerio-Caricetum, in the southern side of Goli is the thermomediterranean Oleo-Pistacietum, and in south of St. Grgur Myrto-Pistacietum. The halophytes in stormy aerosaline cliffs reach up to the peaks of Prvić and Goli, and the calcified reefs of Lithophyllum sp.plur. are in northern shore of St.Grgur and in northeastern cape of Goli.
