Šumarski list br. 3–4, CXXXV (2011), 1-3 maticaesubassociation.This is the only cluster syntaxonomically classified into the grassland order and class. In cluster 4 there are 8 relevés, three made by Domac 1965 on the Pelješac peninsula and five taken by Horvatić 1958 on the island of Hvar. Seven relevés are classified asGenisto-Ericetum verticillatae pinetosum dalmaticae, taken at 500-800 m, and only one relevé asErico-Rosmarinetum pinetosum dalmaticae, taken at 300 m. Cluster 5 comprises sixteen relevés made byTrinajstić 1986 and 1990 on the Pelješac peninsula and on the islands of Hvar and Brač, and one relevé made by Domac 1965 on the Pelješac peninsula. The sixteen relevés in this cluster were taken and classified byTrinajstić as Erico manipuliflorae-Pinetum dalmaticae. The relevé taken by Domac was classified asGenisto- Ericetum verticillatae pinetosum dalmaticae. Cluster 6 includes relevés taken and classified byTrinajstić 1986 and 1990 on the islands of Brač and Korčula. He classified them asQuerco ilicis-Pinetum dalmaticae. The results of the indicator species analysis are shown inTable 1. Two species have the maximal possible indicator value (IV=100) for cluster 7 from the cluster analysis, Juniperus communis L. ssp. nana Syme andSesleria robustaSchott,Nyman&Kotschy. Junipero Table 1.

Associations are clearly divided into three groups.They are divided biogeographically, as the western, central and eastern group of their Mediterranean distribution of Pinus nigra s.l. (Van Haverbeke 2009). On NMS scatterplot the associations are grouped the same way. Group 1consists of associations from Dalmatia and Greece and as such makes the eastern biogeographical group. In this group there are also, and very close ordinated together, Ju nipero sibiricae-Pinetum dalmaticae and Seslerio robustae-Pinetum pallasianae. Association Seslerio robustae-Pinetum pallasianaeBarbéro & Quézel 1976 corr. Bergmeier 1990 was included by Bergmeier1990, and following Horvat’s 1959 concept, into alliance Orno-Ericion Horvatić 1959 and Erico- Pinetea class. In contrast, Brullo & al. 2001 considers that Seslerio robustae-Pinetum pallasianae association should be classified into west Mediterranean classPinoJunipereteaRivas- Martínez1964. Group 2 consists of associations from Iberian peninsula and as such makes the western Mediterranean group. Group 3 makes the central Mediterranean group with associations from Sicily and Corsica. |
