Abstract


The Northern Greece’s mountain pastures correspond at least to three phytosociological orders, the Daphno-Festucetalia which is proper to the Greek mountain, and two others that spread in Europe, the Festuco-Brometalia and the Nardetalia strictae, both found in lower altitude than in Greece. We used the relevés from Thrace, Macedonia and Thessaly from the previous 6 years’ national Conservation Status Assessment of the Natura 2000 network database, that last in 2015, to find the correspondence between the habitat types as they are codified in the Natura 2000 network, the phytosociological order and environmental variables quoted in the relevés. We have selected the relevés with less than 10% trees (417 relevés) and applied frequential analysis to establish clusters of Vegetation Groups (VG) and Relevés Groups (RG), using the same matrice Species x Relevés. We presented then the links betweeen each VG and each RG in a general table with the VG in column and the RG in lines where the RG are defined by their class values (altitude, geology, soil granulometry, rock cover and shrub cover). This could lead us to associate each VG to a phytosociological order and a Natura 2000 habitat type. The results showed for our sample an altitude around 1500m as a limit between, downwards, the Festuco-Brometalia and, upwards, the Daphno-Festucetalia and the Nardetalia. The results showed also the link between the Daphno-Festucetalia and limestone. For the Festuco-Brometalia the substrate is mainly basic, but it is frequently of tertiary deposits and alluvions.
