Šumarski list br. 3–4, CXXXV (2011), 1-3 cepta large number of endemics and these species contribute to territorial autonomy of these orophilous communities (Brullo & al.2001). The NMS in our study showed that according to species assemblage Seslerio robustae-Pinetum pallasianae association is the most resembling with Junipero sibiricae-Pinetum dalmaticae . TheSeslerio robustae- Pinetum pallasianae association is a pioneer forest with a tree layer formed by a local subspecies of Pinus nigra s.l., P. nigra Arnold subsp. pallasiana (Lamb.) Holmboe.The constant dwarf shrubJuniperus communisL. subsp.nanais dominant in the shrub la yer, while the grass species Sesleria robustais dominant in the ground layer, just as in the Dalmatian pine forests on Biokovo.This vegetation occurs on slopes at altitudes from 1,000 and 1,300 m. It is an open pinewood, primarily occurring on rocky soils (Brullo & al. 2001). It was previously classified to the Quercetalia pubescentis, as wasJunipero sibiricae -Pinetum dalmaticaewhich shows similar conditions on habitats where these associations are found.According to Habitat Classification 2003, forests of Dalmatian pine and Pallas’s pine forests are both classified in the same classification group of Mediterranean pine forests with endemic black pines.These forests are of the montane- Mediterranean level, on dolomitic substrate dominated by pines of the Pinus nigra group. Both Pinus nigra subsp.pallasianaandPinus nigrasubsp.dalmaticaare said to be distributed on the Balkan area (Habitat Classification 2003) and appear morphologically and genetically quite similar (Isajev &al. 2004). Seslerio robustae-Pinetum pallasianae is an association very similar toJunipero sibiricae -Pinetum dalmaticae with regard to ecological and phytogeographical attributes, but also concerning its characteristic species structure. This similarity can be explained by the fact that Biokovo is somewhat similar, in some aspects, to REFERENCES Beck-Mannagetta, G., 1901: Die Vegetationsverhältnisse der illyrischen Länder.

Bogunić,F., E.Muratović,S.C.Brown, S.Šiljak- Yakovlev,2003:Genome size and base composition of five Pinus species from the mountains outside the coastal DinaricAlps.The vegetation similarity and the analogy of the phytocenoses of Biokovo are especially distinct in comparison to mountains in Macedonia and Greece (Lovrić 1987) where the mentioned alliance is found. Because Junipero sibiricae-Pinetum dalmaticae is not climazonal vegetation, but rather a local association found in specific conditions, it is rather hard to classify it only by characteristic species. Characteristic species for such specific and locally distributed associations also have a local character, and are often endemic. Therefore, this association has been difficult to classify into the syntaxonomical systemonly according to the number of characteristic species. Other features, exceeding regional ones, should be included. These specific features are recognised in the Habitat Classification 2004 where Mediterranean endemic pines forest have a separate classification group. Our analysis suggests that the association Domac 1965 described is well defined and differs from other vegetation types with Dalmatian pine that occur in the Dalmatian area. However, based on floristic and ecological elements we consider that the association Junipero sibiricae-Pinetum dalmaticaeshould be classified in the Pino-Juniperetea class, the Juniperetalia haemisphaericaeorder, the Berberido craeticae-Juniperion foetidissimae alliance. It can be expected that such a local vegetation type includes local endemic taxa, such as Pinus nigra subsp. dalmatica regarding the phytogeographical particularity of Biokovo Mountain, andPinus nigrasubsp.pallasiana, of which both give their vegetation type special characteristics. Further more, classifying it intoPino-Junipereteaemphasises the relic character of the Mediterranean forests dominated byPinus nigras.l. which they without a doubt have (Brullo &al. 2001), whereas a classification into any other class would repress this aspect into the background. – Literatura Balkan region.
