SYNTAXONOMY AND SYNECOLOGY OF THERMOPHILOUS MEDITERRANEAN PINES Pinus halepensis Mill. AND Pinus brutia Te n. IN GREECE

摘要

Pinus halepensis Mill, and Pmus brutia T e n. are among the most important constituents of forests vegetation around the Mediterranean basin. This paper presents a syntaxonomic overview of P. halepensis and P. brutia dominated vegetation formation in the Mediterranean zone of Greece (Quercetea ilicis), based on the classification of 162 releves from 21 (8 continental and 14 insular) mountainous areas throughout Greece. Three associations and seven sub-associations are described and presented in a synoptic constancy table. Pistacio-Pinetum halepensis De Marco, Veri, C a n e v a 1984 is the most widespread and is found in the entire continental Greece and most islands. It is further subdivided into 2 sub-associations. Junipero phoeniceae-Pinetum brutiae A k -man, Kurt, Demiryurek, Quezel, Kurt, Evren and Kucukoduk 1993, on the other hand, is geographically confined on the eastern parts of Greece. It is further sub-divided into 5 sub-associations. Rhamno lycioidis-Pinetum brutiae nova is found only in Crete and it is further subdivided into 3 sub-associations. The sub-associations are reflecting primarily local peculiarities in the disturbance regime and the influence of local floristic elements.
