Sažetak
The eastern Adriatic coast, besides the Greek coast, is one of the most diverse in the Mediterranean area. There are 1151 islands, islets and reefs, and 80 additional reefs periodically appear above the sea level, depending on tides. During the Pleistocene the Adriatic basin was strongly influenced by the Ice Ages. The recession and elevation of the sea level significantly influenced the coast lines, causing various levels of islands isolation and different encirclement for endemism development. For approximately 250 islands the flora is well known, but for the rest, the data are mostly incomplete or the flora is barely known. SAR extrapolation (Species-Area Relationships) shows that for the whole area of all Croatian islands (approximately 3300 km2) up to 2600 species were expected. Same models shows for whole Mediterranean area along the east Adriatic coast (approximately 17.250 km2) the number of species come up to more than 4000 taxa. From this total number of endemic taxa inside Croatian Mediterranean area are distributed 244 endemic taxa (66%), and the proportion of these endemics per island varies from 0% up to 28.6%. To define the area of particular botanical values, the Important Plant Area (IPA) concept is used. Using IPA criteria the total of 94 IPAs were identified in Croatia with total area of 9543 km2, i.e., 17% of the whole state territory. The land area cover only 0.022 km2 (island Jabuka), and the largest even 2013 km2 (Velebit mountain), while 75% of IPAs have area up to 100 km2. The 66% of IPAs in Croatia is placed in the Mediterranean area defined in wider sense (i.e. including mountains chains in very close vicinity). In the majority of IPAs (60%) the biodiversity threats and negative trends are observed. Straight appliance of the National Ecological Network and Natura 2000 network in preparation, together with regular application of related legislation could protrude possibility of preservation.
