Abstract

New Italian data on the distribution of the Annex I Habitats are reported in this contribution. Specifically, 9 new occurrences in Natura 2000 sites are presented and 34 new cells are added in the EEA 10 km × 10 km reference grid. The new data refer to the Italian administrative regions of Abruzzo, Apulia, Calabria, Latium, Lombardy, Marche, Sardinia, Sicily, Tuscany and Umbria.

Keywords

Introduction

This is the 10th contribution reporting records of new occurrences of Annex I Habitats in Europe. By comparing the results of the 4th Report ex-Art. 17 of Annex I Habitat Monitoring in Europe (Eionet 2019), these cell occurrences are newly recorded for Italy. The related phytosociological relevés of each contribution are going to be archived in the Italian database “VegItaly” (Gigante et al. 2012; Landucci et al. 2012).

Habitats records

Following the standard format of Gigante et al. (2019a), all species data, site data and descriptions of the new habitat records are hereafter provided. We report a synthetic overview in Table 1, offering a summary of the novelties. We used the open source QGIS Geographic Information System (QGIS.org 2020) for mapping purposes. Relevés and figures are provided as Suppl. materials 1, 2.

#102. Annex I Habitat: 1430 Halo-nitrophilous scrubs (Pegano-Salsoletea) (Morabito A, Musarella CM, Spampinato G)

EUNIS Classification system: S6625 – Sicilian halo-nitrophilous scrub (EEA 2021).

Biogeographical Region: Mediterranean

National Habitat Checklist of reference: Italian Interpretation Manual of the Directive 92/43/EEC Habitats (Biondi et al. 2009).

Phytosociological reference: Atriplici halimi-Artemisietum arborescentis Biondi 1988 (1–19) Artemision arborescentis Géhu et al. 1986, Salsolo-Peganetalia Br.-Bl. and O. de Bolòs 1954, Pegano-Salsoletea Br.-Bl. and O. de Bolòs 1954 (Biondi and Blasi 2015)

Geographic information: Italy, Calabria, Vibo Valentia, Ricadi, S. Domenica, 33 m a.s.l., Coordinates: 38.665712°N, 15.862635°E (Suppl. material 1: table S1, Rel. 1).

Cells ID in the EEA reference grid: 10kmE483N175 (Suppl. material 2: fig. S1).

Natura 2000 Site Code: SAC IT9340091 “Zona costiera fra Briatico and Nicotera”

Phytosociological table: Suppl. material 1: table S1; nomenclature and taxa delimitation according to Portal to the Flora of Italy (2024).

Notes: This habitat is characterized by nanophanerophyte shrub vegetation and often by succulent halo-nirophilous chamaephytes, typically found on arid soils, generally salty, in areas with a particularly hot and arid Mediterranean bioclimate of a dry or semi-arid Mediterranean thermal type. This is the first record of 1430 habitat on the Tyrrhenian coast of the Calabria region (Suppl. material 2: fig. S1). Unfortunately, in the Mediterranean region, urbanization and coastalization have had a great impact on this vegetation (Brullo et al. 2013).

#103. Annex I Habitat: 3140 Hard oligo-mesotrophic waters with benthic vegetation of Chara spp. (Mei G, Stinca A)

EUNIS Classification system: C1 – Surface standing waters (EEA 2019)

Cell ID in the EEA reference grid: 10kmE451N226 (Suppl. material 2: fig. S2)

Natura 2000 Site Code: currently not included in any Natura 2000 Site.

Phytosociological table: Suppl. material 1: table S2; nomenclature and taxa delimitation according to Portal to the Flora of Italy (2024).

Notes: The surveys concern the vegetation observed in some water bodies of the Torrente Carpina, characterized by submerged meadows consisting almost exclusively of Chara vulgaris, where, however, vascular species of aquatic and river environments and filamentous algae are also present, albeit sporadically. The surveys conducted in the two pools where the vegetation under examination was better represented, outline aspects typical of communities of freshwater bodies of various sizes and depths that can form in peri-fluvial and lacustrine environments with shallow, calcareous waters, from mesotrophic to slightly eutrophic, both permanent and temporary, colonized precisely by species of Charophyceae that give rise to submerged meadows.

Very widespread in Sardinia, these minor wetlands, even when inserted in a semi-natural territorial matrix, host valuable hydrophytic communities and are of great conservation interest.

#107. Annex I Habitat: 3150 Natural euthrophic lakes with Magnopotamion or Hydrocharition-type vegetation (Gianguzzi L)

EUNIS Classification system: C1 – Surface standing waters (EEA 2019)

Biogeographical Region: Mediterranean

National Habitat Checklist of reference: Italian Interpretation Manual of the Directive 92/43/EEC Habitats (Biondi et al. 2009).

Phytosociological reference: Potamogetonetum perfoliati Miljan 1933, Potamogetonion Libbert 1931, Potamogetonetalia Koch 1926, Potamogetonetea Klika in Klika and V. Novàk 1941 (Brullo et al. 1994; Mucina et al. 2016).

Cell ID in the EEA reference grid: 10kmE471N167 (Suppl. material 2: fig. S4).

Natura 2000 Site Code: currently not included in any Natura 2000 Site, located on the outer edge of the SPA ITA030043 “Monti Nebrodi”.

Phytosociological table: Suppl. material 1: table S6; taxonomic nomenclature according to Portal to the Flora of Italy (2024).

Notes: The habitat concerns a small pond located in the coastal belt of the Nebrodi Mountains, at about 115 m a.s.l. (Suppl. material 2: fig. S5). The biotope had already been identified by Brullo et al. (1994), who noted aspects of a swamp community with Typha dominguensis (referred to the association Typhetum dominguensis) and hygrophilous vegetation with Potamogeton perfoliatus (referred to the association Potamogetonetum perfoliati). Recent monitoring has confirmed the presence of the habitat, with additional late-spring hygrophytic facies featuring Potamogeton polygonifolius. It is situated on the margin of a monophytic community with Cyperus papyrus (cl. Phragmito-Magnocaricetea Klika in Klika et Novak 1941), among other rare species in Sicily (even if of probable anthropogenic introduction). This further note confirms the phytogeographic interest of the humid environments of Sicily and its various habitats, often found in residual and fragmentary locations, both in the Nebrodi Mts. (De Castro et al. 2008; 2015; Troia et al. 2017), and across other areas of the island (Caldarella et al. 2009, 2013, 2021; Gianguzzi et al. 2013; Gianguzzi and La Mantia 2004, 2008).

Phytosociological table: tables 4 and 10 in Tomaselli et al. (2020); taxonomic nomenclature according to Pignatti (2017–2019).

Notes: Temporary ponds are a type of biologically important habitat that has specialized vegetation dominated mainly by therophytes (Brullo et al. 2022). However, it may also be associated with dwarf geophytes and hemicryptophytes (Brullo et al. 2023). The Isoeto-Nanojuncetea class in Apulia was recently studied by Tomaselli et al. (2020). They reported several new associations which were later validated by Tomaselli et al. (2022), in accordance with the 4th edition of the International Code of Phytosociological Nomenclature (Theurillat et al. 2021). These new records are based on the phytosociological research carried out by Tomaselli et al. (2020).

#109. Annex I Habitat: 3170* Mediterranean Temporary Ponds (Di Pietro R, Minutillo F)

Geographic information: Italy, Lazio, Valle San Vito, Via Limatella, 70 m a.s.l., Coordinates: 41.373151°N, 13.337569°E (Suppl. material 1: table S7, Rel. 1)

Cells ID in the EEA reference grid: 10kmE460N203 (Suppl. material 2: fig. S6)

Natura 2000 Site Code: SAC IT6040006 “Sughereta di San Vito”

Phytosociological table: Suppl. material 1: table S7; taxonomic nomenclature according to Bartolucci et al. (2018) and later updates.

Notes: Temporary ponds habitats are characterized by ephemeral communities normally developed within patches of few square meters size. The new reports here described regard a SAC of the Lazio administrative region, the “Sughereta di San Vito”, that, in turns, is included in the Ausoni-Lago di Fondi Regional Park. It is a large natural forest area developed on the Terra rossa substrates, which is characterized by the dominance of Quercus suber with an understorey mainly composed of Erica arborea and Cistus salvifolius, together with several other Mediterranean maquis species such as Pistacia lentiscus, Rhamnus alaternus, Phillyrea latifolia, Myrtus communis. At present, the Quercus suber forest of the San Vito valley is to be considered the largest cork oak wood of the whole Peninsular Italy and it is almost completely assigned to Habitat 9330. However, where the forest canopy is not completely closed, such as where limestone outcrops emerge or along the numerous paths that cross the forest and which were used until a few years ago for the exploitation of cork, communities other than forest ones can be found. In fact, especially within depressed and flat areas subject to temporary flooding during the rainy periods, we found small size patches of meso-hygrophilous mixed therophytic-hemycryptophytic communities characterized by the presence of Isoetes diuraei and other species which often characterize temporary ponds such as Juncus bufonius, Serapias lingua, and Ranunculus sardous. These communities are strongly at risk at present. In fact, the colonization of the open areas from the Mediterranean scrub species together with the generalized decrease in rainfalls that have been occurring over the last two decades, are progressively reducing the environments suitable for the development of temporary ponds. Accordingly, these environments to be invaded by perennial grasses and sedges, such in particular Carex flacca and Poa trivialis, or by other perennial species such as Oenanthe pimpinelloides. This new report, together with others published recently (Rivieccio et al. 2022), is making the coastal sector of southern Lazio emerge as one of the most prolific for the development of the communities belonging to Habitat 3170 in Italy. To note that no species of the genus Isoetes have currently been reported either for the SAC area or for the Ausoni mountains floristic list (see Lucchese and Lattanzi 2000) (Suppl. material 2: fig. S7).

Notes: The Salicetum apenninae plant community refers to Salix apennina and S. purpurea pioneer willow woods that develop near water sources and within watersheds in mountain and sub-mountain sectors of the Central Apennines. Usually, these communities have a limited extension and a high-shrub growth that rarely exceeds 5 m in height. Salicetum apenninae association in the study area is present in the pioneer aspect of this community. Locally, due to the presence of the differential species Eupatorium cannabinum and Campanula trachelium, the subassociation eupatorietosum cannabini appears, indicating conditions of water stagnation and accumulation of organic matter.

Notes: The relevés have been carried out in the calcareous outcrops of the area, characterised by open xerothermophile pioneer communities. Interestingly, the sampling area is formed by a locally rare grey calcarenitic outcrop. The surrounding areas of the cell are characterised by other types of geological outcrops, i.e. scaglia, jasper, shales, volcanic sediments and pliocenic clays. All investigated relevés are similar in geomorphological features, being on grey calcarenitic limestone type with elevated slopes and scarce soil. The reported presence of EU Habitat 6110* is to be considered extremely localised for this investigated area within the cell 10kmE445N220.

Natura 2000 Site Code: currently not included in any Natura 2000 Site

Phytosociological table: Suppl. material 1: table S12; taxonomic nomenclature according to Bartolucci et al. (2018) and later updates.

Notes: Perennial hygrophilous and nitrophilous vegetation with megaforbs that can be included in habitat 6430 (new habitat for the Puglia Region). In particular, the communities investigated belong to the subtype: 37.7 – Wet and nitrophilous tall herb edge communities, along water courses and woodland borders. This vegetation types are found in areas where the stream current loses its speed leading to the deposit of a large part of the biomass transported. These environmental conditions favor the entrance in the community of slightly nitrophilous species. The syntaxonomic reference at the rank of association could be the Phalarido-Petasitetum hybridi due to the clear dominance of Petasites hybridus (Suppl. material 2: fig. S16), although this reference is to be considered absolutely preliminary. Also, at the ranks of alliance and order the possible reference is not univocal. The Phalarido-Petasitetum hybridi shows similarities for both the Convolvuletalia sepium Tx. ex Moor 1958 and the Galio-Alliaretalia Oberd. in Gors and T. Muller 1969. On the basis of Mucina et al. (2016) the reference class should be Epilobietea angustifoliae whereas, according to Biondi et al. (2009), it should be more properly assigned to the Filipendulo ulmariae-Convolvuletea sepium Géhu and Géhu-Franck 1987 or to the Galio aparines-Urticetea dioicae Passarge ex Kopecký 1969.

Natura 2000 Site Code: currently not included in any Natura 2000 Site.

Phytosociological table: Suppl. material 1: table S13; taxonomic nomenclature according to Portal to the Flora of Italy (2024).

Notes: These species-rich, mesic semi-natural grasslands (Suppl. material 2: fig. S18) are managed as both pastures and hay meadows, which is a traditional management strategy of central Apennines. Extensive sheep grazing is present from late summer to early spring. Grazing is then stopped by the end of March to let the plants grow, and hay harvesting is carried out usually by the end of June. Despite not being the most typical aspect of habitat 6510 (Arrhenatherion elatioris), such pastures-meadows are still considered examples of such habitat. In fact, they represent the typical lowland hay meadows occurring in the biogeographic context of the Italian Peninsula, where the Arrhenatherion elatioris vegetation is missing and other alliances, such as Salvio-Dacylidion and Ranunculion velutini, are considered appropriate syntaxonomic references for habitat 6510 (Biondi et al. 2009). Consistently, habitat 6510 is very rich in species and complex, so that target species for monitoring purposes should be identified regionally (Angelini et al. 2016). In the discovery area, such grasslands are still very common and inserted into a type 2 High Nature Value agricultural landscape, i.e., farmland dominated by low intensity agriculture or a mosaic of semi-natural and cultivated land and small scale features (Fanfarillo et al. 2017a,b). Nearby, some aspects of the habitat 6510 were also recorded in traditionally managed olive groves (Fanfarillo et al. 2019).

Notes: This is the fourth contribution regarding habitat 7210* in the Sardinia region, with the first records reported at Platamona, Li Cossi, and Sant’Imbenia coastal areas (Gigante et al. 2019b; Gianguzzi et al. 2020; Morabito et al. 2023). The reported presence of Cladium mariscus in the Nuoro province is credited to Desfayes (2008), to whom we are grateful for providing precise coordinates. The habitat here appears highly fragmented and impacted by extensive coastal usage. Small and large nuclei of C. mariscus dominant, with Desfayes (2008) suggesting a large one with an extension of around 500 m2, are spaced perpendicular all along the Lido, indicating a historically larger distribution. The presence of invasive alien species, areas being used as landfills, and a noticeable progressive phenomenon of burial, also attributed to the litter of pine and eucalyptus planted nearby, highlight the strong human impact on these valuable plant communities.

Notes: Recent studies in phytosociology have focused on the oleaster vegetation of Sicily, accompanied by distributional analyses that have updated information on habitat 9320 (Bazan et al. 2021; Rivieccio et al. 2023). Additional research in geobotany that examines both the flora and plant communities in central Sicily (Gianguzzi et al. 2014a, 2014b, 2016) has uncovered an additional notable instance of this habitat in Agrigento province. This formation has been phytosociologically referred to the association Ruto chalepensis-Oleetum sylvestris subass. oleetosum sylvestris (Suppl. material 2: fig. S25). Historically, oleasters were commonly utilized as rootstocks for olive trees in agricultural settings. Changes in agricultural practices (Bazan et al. 2020) and the neglect of ancient olive orchards, some of which are several hundred years old (Schicchi et al. 2021), have facilitated the resurgence of oleaster populations.

Geographic information: Italy, Sicily, Altofonte, near Cozzo Maglio, 250 m a.s.l., Coordinates: 38.054277°N, 13.297671°E (Suppl. material 1: table S18, Rel. 1); Italy, Sicilia, Altofonte, near Cozzo Maglio, 280 m a.s.l., Coordinates: 38.054458°N, 13.298639°E (Suppl. material 1: table S18, Rel. 2).

Cell ID in the EEA reference grid: 10kmE461N167 (Suppl. material 2: fig. S26).

Natura 2000 Site Code: currently not included in any Natura 2000 Site.

Phytosociological table: Suppl. material 1: table S18; taxonomic nomenclature according to Portal to the Flora of Italy (2024).

Notes: The habitat consists of small forest clusters of Quercus suber, located on isolated quartzarenitic outcrops in the Palermo Mts., in areas largely dominated by carbonate substrates (limestone, dolomite, etc.). From a syntaxonomic perspective, they are referred to the association Genisto aristatae-Quercetum suberis subass. pistacietosum lentisci (Brullo et al. 2008; Suppl. material 2: fig. S27), widespread in the northern sector of Sicily on loosely coherent siliceous substrates (quartzarenites, as well as sands, flysch, etc.), in markedly xeric conditions. It is reported for the elevations of the Trapanese [Zingaro Nature Reserve, Bosco Scorace, Mt. Inici, Bosco Calatafimi (Bazan et al. 2021; Rivieccio et al. 2022)], Palermo area [Misilmeri, Mt. Cani (Caldarella et al. 2009), Bosco Ficuzza, Bosco Granza], Madonie Mts. Nebrodi Mts., and Peloritani Mts. (Gianguzzi et al. 2016). These clusters are particularly threatened, due to their rarity in the territory but also because of frequent fires affecting the area (Capotorti et al. 2020).
