Global and Regional IUCN Red List Assessments: 1

In this contribution, the conservation status assessment of six plant species according to IUCN categories and criteria are presented. It includes the assessment at global level of Linaria tonzigii Lona, Allium garganicum Brullo, Pavone, Salmeri & Terrasi, Ferula arrigonii Bocchieri, Orchis patens Desf. subsp. patens and Armeria saviana Selvi and the assessment at regional level (Italy) of Viola jordanii Hanry

A novel insight into the remnants of hygrophilous forests and scrubs of the Po Plain biogeographical transition area (Northern Italy)

Hygrophilous forests and scrubs are ecotonal habitats providing essential ecosystem services, especially in human-modified landscapes; nevertheless, they are among the most threatened habitats worldwide. A sound knowledge of waterside woody vegetation provides a valuable basis for interventions of renaturation of waterbodies. This paper focuses on peculiar communities that occur in riparian and swamp areas of the Po Plain, a broad ecotonal area between the Mediterranean and Temperate regions. The study allowed the description of six new associations. Moreover, it provides a detailed picture of Dioscoreo communis-Populetum nigrae (Populetalia albae) and Amorpho fruticosae-Salicetum albae (Salicetalia purpureae), an overview of Salicetum triandrae (Salicetalia purpureae) at the national and European level, and an update of the alliance Dioscoreo-Ulmion minoris, which is better characterized, classified in Populetalia albae and enlarged to include five associations of elm-oak-rich forests of the Po Plain lowlands and the Karst. Dioscoreo-Ulmion includes, besides Lamio orvalae-Ulmetum minoris, also Polygonato-Quercetum roboris and three new associations: Vinco minoris-Ulmetum minoris and Salvio glutinosae-Quercetum roboris from Po Plain rivers and the karstic lakeshore Rhamno catharticae-Ulmetum minoris. The new arrangement of Dioscoreo-Ulmion results from an analysis of Po Plain elm-rich forests including stands so far attributed to the critical alliance Alnion incanae; the presence of Querco-Ulmetum minoris in Italy is discussed. Two new associations are attributed to Prunetalia spinosae: Salici eleagni-Juniperetum communis and Ulmo minoris-Paliuretum spinae-christi. Stands from the Rivers Isonzo and Tagliamento referred to Veratro nigri-Fraxinetum excelsioris and to the new association Carici albae-Fraxinetum excelsioris represent the outermost expressions of the Ostryo-Tilion ravine forests extending towards the High Plain. A Salix alba swamp forest, Galio palustris-Salicetum albae, is reported for the first time in Italy and attributed to Alnetea glutinosae

La vegetazione dei muri del Friuli-Venezia Giulia (NE Italia) e suo inquadramento nel contesto europeo

WALL VEGETATION OF FRIULI-VENEZIA GIULIA (NE ITALY) IN THE EUROPEAN CONTEXT. Sintaxonomy of the wall vegetation in Friuli-Venezia Giulia was investigated. The phytocoenosis have been included in The order Tortulo-Cymbalarieralia Segal 1969 of the class Asplenietea trichomanis (Br.-BI. in Meier et Br.-BI. 1934) Oberd. 1977. They can not be assigned to the class Cymbalario-Parietarietea diffusae Oberd. in Oberd. et al. 1967 for the lack of typical stenomediterranean species. The releves of the North-Adriatic Karst and South-Eastern Alps were compared to syntetical tables of wall vegetation of Central Europe and Italy

Vascular flora of Friuli-Venezia Giulia. An annotated catalogue and synonymic index

LA FLORA VASCOLARE DEL FRIULI-VENEZIA GIULIA. CATALOGO ANNOTATO E INDICE SINONIMICO. An annotated catalogue and a synonymic index of the vascular flora of Friuli-Venezia Giulia (NE ltaly) are presented. Besides the main list of 3388 infrageneric entities, three appendices are reported, the first one including not yet stabilized neophytes and ephemerophytes, the second one "locally extinct" taxa, and the third one spurious taxa. Pedicularis recutita L. var. trichocalycina Poldini and Veratrum x tonussi Poldini are described as new, and some new combinations are proposed

La vegetazione del litorale sedimentario del Friuli-Venezia Giulia con riferimenti alla regione alto-adriatica

THE VEGETATION OF THE SEDIMENTARY COAST OF FRIULI-VENEZIA GIULIA (NE-lTALY) WITH PARTICULAR REFERENCE TO THE NORTHERN ADRIATIC REGION. This paper is devoted to the study of the psammophilous and halophilous vegetation of the Northern Adriatic Sea (from Sefovlje, Republic of Slovenia, to the mouth of the Po river) and particularly to the definition of a phytosociological scheme for the vegetation of the sedimentary coast of Friuli-Venezia Giulia. Due to its alluvial origin, the study area is geomorphologically homogeneous, being constituted by lagoons bordered by sandy shorelines, and in the Mediterranean basin it is distinctive because of a strong Eurosiberian climatic influence, high tides and wet salted soils. About 900 relevés taken from the literature and 65 unpublished relevés from Friuli-Venezia Giulia were considered. The multivariate analysis of the relevés allowed to reassess the syntaxonomical position of several associations, placed by some Authors into other classes of vegetation. Some problems arised with the halophilous vegetation, as some species, although characteristic of their classes, are present with high frequencies also in other classes. Furthermore, the boundaries between classes are rather vague if only the floristic composition is considered. However, this problem can be overcome by taking into account also structural data (life form and growth form). These syntaxonomical difficulties reflect the peculiar character of a vegetation which seems monotonous, but is on the contrary very heterogeneous, being constituted by a fine scale mosaic. The vegetation of the study area is more similar to that of the western than to that of the Eastern Mediterranean coast, and. has a strong affinity with the vegetation of Atlantic Europe
