The geological and phytoclimatic heterogeneity of the island and the wide ecological amplitude of the holm-oak, result in a large phytocoenotic diversity of the Sardinian holm-oak woods. These are referred to five associations: Pyro amygdaliformis-Quercetum ilicis, Prasio majoris-Quercetum ilicis ass. nova, Galio scabri-Quercetum ilicis, Saniculo europaeae-Quercetum ilicis ass. nova and Aceri monspessulani-Quercetum ilicis. From the phytogeographic point of view, in the subhumid-humid, meso-supramediterranean bioclimatic belts of Sardinia the presence of the association Galio scabri-Quercetum ilicis is found to be remarkable. As far as the cork-oak woods are concerned, the associations Galio scabri-Quercetum suberis and Violo dehnhardtii-Quercetum suberis ass. nova are here reported. The Sardinian-Corsican holm-oak and cork-oak woods define the western limit of the European central-Mediterranean alliance Fraxino orni-Quercion ilicis of which in Sardinia there are many characteristic and differential entities. In the Sardinian-Corsican holm-oak woods, however, there are endemic entities (Arum pictum ssp. pictum, Helleborus lividus ssp. corsicus, Digitalis purpurea var. gyspergerae, Quercus ichnusaePaeonia morisii) and other western-centred entities with little or no spread on the Italian peninsula (Galium scabrum, Clematis cirrhosa and Teucrium scorodonia). These entities allow the proposal that within the alliance Fraxino orni-Quercion ilicis can be recognised the new Sardinian-Corsican suballiance Clematido cirrhosae-Quercenion ilicisPrasio majoris-Quercetum ilicis ass. nova), which is endemic to the Sardinian and Corsican sectors of the Italo-Tyrrhenian Province. Consequently, the suballiance Fraxino orni-Quercenion ilicis, which is the typical of the alliance Fraxino orni-Quercion ilicis, has also been proposed.

Syntaxonomical revision of Quercetalia pubescenti-petraeae in the Italian Peninsula / C. Blasi in Fitosociologia, vol 41 n° 1 (2004)

Blasi, Auteur ; Romeo Di Pietro, Auteur ; L.

(suball.: Teucrio-Quercenion cerridis suball. nov., Ptilostemo-Quercenion cerridis); Pino-Quercion congestae (suball.: Pino-Quercenion congestaeQuercenion virgilianae suball. nov.) and Erythronio-Quercion petraeae. The Quercion pubescenti-petraeae is a sintaxon with a sub-continental character and within the Italian Peninsula it is restricted to Ligurian-Piedmontese Apennine in the form of the sub-alliance Buxo-Quercenion pubescentis. Carpinion orientalis is a sintaxon with oceanic/suboceanic features, which is widely distributed along the entire Italian Peninsula. It occurs mainly on limestone substrates forming woodlands which can be potential vegetation types and also woods of secondary origin and evolution. The Teucrio-Quercion cerridis is an alliance which is widely distributed within central and southern Italy, where it finds its coenological optimum on acid, subacid or neutral substrates such as volcanic outcrops, flysch, sandstones or clayey-arenaceous sediments. In this alliance are included both thermophilous Quercus cerris and Quercus petraea woodlands of Tuscany, Umbria and northern Latium, together with Quercus cerris and Quercus frainetto woodlands of southern Italy. The alliance Pino-Quercion congestae is restricted to Sicily and southern Calabria, and includes Quercus virgilianaQ. dalechampii hilly woodlands, and also sub-montane and lower-montane Quercus congesta woods. Finally, Erythronio-Quercion petraeae behaves as a typical mesophilous and microthermic alliance which exhibits clear biogeographical similarities with towards the central-european woodlands. This alliance is restricted to the northern Apennines where it is in geo-serial contact with Carpinion betuli, Quercion robori-petraeae and Fagion woodlands.
