New and validated syntaxa for the checklist of Italian vegetation

Abstract

We drew up a checklist of the Italian vegetation (http://www.prodromo-vegetazione-italia.org/), up to the syntaxonomical rank of alliance. During the compilation of this checklist, we observed that some syntaxa were invalidly published. For this reason, in this article we validated some syntaxa names and, at the same time, described new syntaxa of different hierarchical levels. Therefore, 10 new orders, 1 new suborder, 18 new alliances, 3 new suballiances and 5 new associations are described here. These new syntaxa belong to the following classes: Adiantetea capilli-veneris, Parietarietea judaicae, Thlaspietea rotundifolii, Artemisietea vulgaris, Stellarietea mediae, Galio aparines-Urticetea dioicae, Mulgedio alpini-Aconitetea variegati, Trifolio medii-Geranietea sanguinei, Festuco-Seslerietea, Salicetea herbaceae, Festuco valesiacae-Brometea erecti, Molinio-Arrhenatheretea, Cisto cretici-Micromerietea julianae, Rhamno catharticae-Prunetea spinosae, Salici purpureae-Populetea nigrae, Salicetea purpureae, Quercetea ilicis and Querco roboris-Fagetea sylvaticae

A test on Ellenberg indicator values in the Mediterranean evergreen woods (Quercetea ilicis)

“…Another result worth of discussion is related to the cluster 2, which groups the relevés of Pistacio lentisciPinetum halepensis: until recent times, this association was framed into the alliance Oleo sylvestris-Ceratonion siliquae; according to our results, its floristic settlement differs enough to propose its inclusion into the alliance Pistacio lentisci-Pinion halepensis Biondi, Blasi, Galdenzi, Pesaresi & Vagge 2014. This last alliance has been recently described to group the vegetation dominated by Pinus halepensis, found on steep coastal slopes throughout the Mediterranean region (Biondi et al 2014a). Further and broader investigations would be desirable to evaluate whether this recently described alliance deserves the recognition of an autonomous order, described as Pinetalia halepensis Biondi, Blasi, Galdenzi, Pesaresi & Vagge 2014, which seems inconsistent with our results.…”

“…In the previous studies, the community Carici remotaeFraxinetum oxycarpae was classified into different alliances: Alno-Ulmion, Alno-Quercion roboris, Alnion incanae, Carici remotae-Fraxinion oxycarpae, Populion albae [5,9,10,18,29,31,37]. Our research shows a high coincidence with the alliance Carici remotae-Fraxinion oxycarpae, as it is defined in the syntaxonomic overview of the vegetation of Italy [9,18].…”

“…The surface of the plots was 400 m², inclination 0˚, and the terrain altitude ranged between 10 and 18 m. The plant nomenclature is aligned with the Flora Croatica Database [16], and mosses with Atherton et al [17]. Syntaxonomic nomenclature of higher units mostly follows the overviews by Biondi et al [18] for Fraxinus angustifolia stands, and Košir et al [19] for mixed hardwood stands. The local syntaxa from previous studies are presented in their original form, whereby a part of the syntaxa is described according to ICPN [20], and a part of them followed the multidimensional distribution of vegetation units [21].…”
