LE SPECIE E LE FITOCENOSI FORESTALI NEL PAESAGGIO VEGETALE DEI MONTI SICANI (Entroterra della Sicilia centro-occidentale)

The relictual woodlands with Laurus nobilis L. of Sicily (Italy): phytosociological, phytogeographical, ecological and distributional considerations

Distribution, ecology and conservation survey on theCeltis tournefortiisubsp.aetnensis(Celtidaceae: Cannabaceae) populations in Sicily

Results of research on the Celtis tournefortii subsp. aetnensis (Celtidaceae-Cannabaceae) populations in Sicily, based on the monitoring of the various nuclei distributed in the territory, are presented. In particular, two new important unpublished stations located in the southern part of the Sicani Mountains, widespread over an area of approximately 75 hectares, are reported. It is highlighted that the species, besides the lava flows of the western slope of Mount Etna (Catania province), is tied to conoids present in five other disjointed sub-ranges, often with fragmentary and relictual stations: (1) Nebrodi Mountains inland (Cesarò territory, Messina province); (2) Madonie Mountains inlan…

Contribution to the phytosociological characterization of the forest vegetation of the Sicani Mountains (inland of north-western Sicily).

The results of a phytosociological survey on the main forest vegetation aspects of the Sicani Mountains (inland of north-western Sicily), in turn included in the homonymous Regional Park recently established, are presented. This expansive territory (43,687 hectares), located between the Agrigento and Palermo provinces, is mainly composed by carbonate and silico-carbonate formations of the Sicani Units, whose highest peaks are represented by Mount Cammarata (1578 m a.s.l.), Mount delle Rose (1436 m), Pizzo Cangialoso (1420 m) and Mount Pernice (1393 m). Under the bioclimatic aspect, the area falls within the thermo- and supramediterranean belts, with ombrotype ranging from upper dry (annual …
