|Summary: In 2001, a series of floristic and vegetational researches were made in a wider area of Šibenik. Thus, the study from the phytosociological and syntaxonomical point of view of the vegetation on the Oštrica peninsula, situated in the south-east from Šibenik, was performed (cf. Fig.1). The entire peninsula is built of cretaceous limestones, and through the centuries it was cultivated partly by the man who made terraces retained by the walls of removed stones. The soil covering the terraces and pockets between stone blocks is mostly red soil. The climate is of Mediterranean type with mild winters and hot summers. The average temperature in January is 6.8 oC and in July 25 oC, the average minimum being -1.3 oC. The total amount of precipitation is about 770 mm/m2, and the largest amounts of rain fall in autumn and winter (cf. Prgin 1994; Jurković 1995).A total of 20 vegetational relevés was made in macchia which covers almost the entire peninsula. The relevés were made in the way to represent an as large surface area as possible, so with 20 relevés most of the peninsula surface area is represented optimally. The border part by the sea (halophytic vegetation), the very small grassland areas and the Aleppo Pine stands have not been researched because of their unsufficient differentiation. The relevés were made and analyzed using the classical Braun-Blanquet´s method (cf. Braun-Blanquet 1964). All records were subjected to two numerical methods of analysis - the cluster analysis and the multidimensional scaling (Sharma 1996; McGarigal et al. 2000). The numerical analysis was made using the SYN-TAX 2000 program package (Podani 2001).|
By the syntaxonomical research of the Oštrice peninsula forest vegetation two clearly differentiated associations were determinated - Pistacio lentisci-Juniperetum phoeniceae Trinajstić 1987 and Fraxino orni-Quercetum ilicis H-ić (1956) 1958. In addition to these two clearly noticeable associations, which form the largest part of the peninsula vegetational cover, the transitions corresponding more or less to one association or the other were noticed, too (cf. Tab. 1; Fig. 2 and 3).
The association Pistacio lentisci-Juniperetum phoeniceae is the initial forest association characterized by a relatively small number of species (10-20; cf. Rauš 1981; Trinajstić 1987, 1995, 2000; Pandža 1995, 1998) although by the latest research a much higher number of species was determined (56) of which 15 were new for the association (cf. Jasprica et al. 2000; Kovačić et al. 2001). On the Oštrica peninsula, 25 species were determined in this association, that corresponds more with the earlier researches. To this association the relevés under numbers 14-20 belong, while those under numbers 1, 2, 3 and 6 (A, Tab. 1, Fig. 3) are very similar to this association but with a reduced number of the differential species Pistacia lentiscus and Juniperus phoenicea and a considerably larger share of the species Quercus ilex. It is, therefore, clearly visible that the succession takes place in the direction toward the association Fraxino orni-Quercetum ilicis. This is supported also by the relevés under numbers 7, 9, 10 and 12 (B, Tab. 1, Fig. 3), which are very similar to the association Fraxino orni-Quercetum ilicis with an even larger share of the Q. ilex and a considerably smaller share of the association Pistacio lentisci-Juniperetum phoeniceae. By further increase of the share of the Q. ilex and the occurrence of the Fraxinus ornus (the relevés no. 5, 8, 11, 13), it is formed a climazonal vegetation with the association Fraxino orni-Quercetum ilicis, which presents the terminal development phase of the Oštrica peninsula forest vegetation. The only exception is the relevé under number 4 (C, Tab. 1, Fig. 3), which by all analysis methods differs significantly from other relevé and is characterized by a very frequent occurrence of the Ephedra campylopoda and Prasium majus, which are differential species of the alliance Oleo-Ceratonion. To this link belongs the association Pistacio lentisci-Juniperetum phoeniceae, but other differential species of this alliance are missing. This alliance does not belong to the association Fraxino orni-Quercetum ilicis either, because the share of the Q. ilex is very small while the Faxinus ornus is not present at all. During the succession, this relevé very likely will become closer to the climazonal association Fraxino orni-Querceum ilicis, but in that the share of the Ephedra campylopoda and Prasium majus will decrease with the canopy thickening and the increase of the share of the Q. ilex (cf. Tab. 1; Fig. 2 and 3).
The Oštrica peninsula configuration being such that here, potentially, the association Fraxino orni-Querceum ilicis can be developed almost over the whole peninsula, it is assumed to have been developed here from the association Pistacio lentisci-Juniperetum phoeniceae. Presumably, after the anthropogenetic impact (grazing, burning, vineyards) has ceased here, at the beginning the association Pistacio lentisci-Juniperetum phoeniceae has formed which then by fast sucession processes on the deeper soil and in more protected expositions developed into the association Fraxino orni-Querceum ilicis. Similar succession processes take place in the south Adriatic area, too (cf. Trinajstić 2000; Jasprica et al. 2000; Kovačić et al. 2001), but there different combinations of species are involved.
