Introduction

This is the fifth 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 reported and 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 Tab. 1. We used the open source QGIS Geographic Information System (QGIS.org 2020) for mapping purposes.

Distribution in Italy of the Habitat 3170*: in black the new cell, in grey the cells officially reported in the 4th Habitat report ex-Art. 17 (period 2013–2018), in white (black outline) the cells later reported for Sardinia region (Gigante et al. 2019a).

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

Phytosociological table : Tab. 2; taxonomic nomenclature according to Bartolucci et al. (2018).

Notes : The habitat is located in the outer belt of Mediterranean temporary ponds and waterlogged soils in patchwork with the vegetation dominated by Pistacia lentiscus and Myrtus communis (Bagella et al. 2009) inside a private biological farm. As already reported in Rivieccio et al. (2020), the area is rich in wetlands, whose persistence is favored by traditional farming practices (Bagella et al. 2016).

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

Phytosociological table : Tab. 3; taxonomic nomenclature according to Portale della Flora d’Italia (2020).

Notes : The vegetation of Alysso-Sedion albi for central Italy is little reported in the phytosociological literature and no Sedum album-dominated coenosis has been framed yet (Venanzoni & Gigante 1999; Di Pietro et al. 2006). The recorded community (Fig. 3) occurs on carbonate rocky outcrops below the “Rocca Albornoz” fortress, near the border of the Natura 2000 SAC IT5210064 “Monteluco di Spoleto”, but outside. The Habitat spreads on the carbonatic rocks over an area of about 600 sqm. In several points it is invaded by the alien invasive Ailanthus altissima (Mill.) Swingle. The present finding occurred during the surveys carried out with the financial contribution of the Life Integrated project “LIFE IMAGINE Umbria - Integrated MAnagement and Grant Investments for the N2000 NEtwork in Umbria”.

#23. Annex I Habitat: 91E0* Alluvial forests with Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae) (Calvia G., Bonari G., Bacchetta G.)

EUNIS 2020 classification system : T14 (formerly: G1.3) Mediterranean and Macaronesian riparian forests (Chytrý et al. 2020).

Biogeographical Region : Mediterranean.

National Habitat Checklist of reference : Manuale Italiano di interpretazione degli habitat della Direttiva 92/43/CEE (Biondi et al. 2009).

Phytosociological reference : Osmundo regalis-Alnetum glutinosae Camarda 1995; Osmundo-Alnion glutinosae (Br.-Bl. et al. 1956) Dierschke et Rivas-Mart. in Rivas-Mart. 1975; Populetalia albae Br.-Bl. ex Tchou 1948; Salici purpureae-Populetea nigrae (Rivas-Mart. et Cantó ex Rivas-Mart. et al. 1991) Rivas-Mart. et Cantó 2002 (Biondi and Blasi 2015).

Cell ID in the EEA reference grid : 10kmE425N196 (Fig. 4).

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

Phytosociological table : Tab. 4; taxonomic nomenclature according to Bartolucci et al. (2018).

Notes : This priority habitat occurs scattered in the island of Sardinia (Bacchetta et al. 2009) and is often represented by the association Osmundo regalis-Alnetum glutinosae Camarda 1995. This is a typical association represented by edapho-hygrophilous meso-woods (10–20 m high) growing along oligotrophic rivers and streams, from the sea level up to 800 m of elevation. They are calcifuge formations linked to moist sandy to gravelly soils in the Mediterranean Oceanic Pluviseasonal bioclimate, with thermotypes ranging from the thermo-Mediterranean to the meso-Mediterranean and ombrotypes from lower subhumid to lower humid (Angius and Bacchetta 2009). It is classified within the W-Mediterranean alliance Osmundo-Alnion glutinosae (Br.-Bl. et al. 1956) Dierschke et Rivas-Mart. in Rivas-Mart. 1975 and the Tyrrhenian sub-alliance Hyperico hircini-Alnenion glutinosae Dierschke 1975 (Angius and Bacchetta 2009; Landi and Angiolini 2010). At the site here reported (Fig. 5), the trees of Alnus glutinosa are only occasionally dominant due to relatively recent wildfires and extreme rain events. For this reason, Osmunda regalis L. is often dominant, forming a dense undergrowth along streambanks and islets.

Natura 2000 Site Code : The stand of Rel. 1 is included in the SAC ITA010005 “Laghetti di Preola e Gorghi Tondi e Sciare di Mazara” and SPA ITA010031 “Laghetti di Preola e Gorghi Tondi, Sciare di Mazara e Pantano Leone”; the stand of Rel. 2 is currently not included in any Natura 2000 Site.

Phytosociological table : Tab. 5; taxonomic nomenclature according to Bartolucci et al. (2018).

Notes : The phytosociological interpretation of Olea europaea L. var. sylvestris (Mill.) Lehr. communities by Gianguzzi and Bazan (2019, 2020) has allowed a correct interpretation and an update of distribution of the Habitat 9320 in Sicily (Gianguzzi et al. 2020). In the Region, botanical and phytosociological research have indeed provided new insights into the status and distribution of habitat and species for the implementation of the 4th Italian Report of Habitats (e.g., Troia et al. 2012; De Castro et al. 2015; Gianguzzi et al. 2013, 2014a, 2014b, 2015, 2016).

Recent surveys have provided two new records of 9320 habitat in Sicily referred to Chamaeropo humilis-Oleetum sylvestris acanthetosum mollis and Ruto chalepensis-Oleetum sylvestris oleetosum sylvestris. The second phytocoenosis represents the first record of a wild olive formation growing on gypsum substrates. Its location outside Natura 2000 network should receive special attention.

#25. Annex I Habitat: 9330 Quercus suber forests (Bazan G., Gianguzzi L.)

EUNIS Classification system : T21 (formerly: G2.1) Mediterranean evergreen Quercus forest (Chytrý et al. 2020).

Biogeographical Region : Mediterranean

National Habitat Checklist of reference : Manuale Italiano di interpretazione degli habitat della Direttiva 92/43/CEE (Biondi et al. 2009).

Phytosociological reference : Genisto aristatae-Quercetum suberis Brullo 1984 pistacietosum lentisci Brullo, Gianguzzi, La Mantia et Siracusa 2008; Erico arboreae-Quercion ilicis Brullo, Di Martino et Marcenò 1977; Quercetalia ilicis Br.-Bl. ex Molinier 1934; Quercetea ilicis Br.-Bl. in Br.-Bl., Roussine et Nègre 1952 (Biondi and Blasi 2015).

Geographic information : Italy, Sicilia, Sciacca, Sovareto, 50 m a.s.l., Coordinates: 37.500410 N, 13.121535 E (Tab. 6, Rel. 1); Coordinates: 37.500605 N, 13.121616 E (Tab. 6, Rel. 2).

Cell ID in the EEA reference grid : 10kmE459N160 (Fig. 7).

Distribution in Italy of the Habitat 9330: in black the new cell, in grey the cells officially reported in the 4th Habitat report ex-Art. 17 (period 2013-2018; Eionet 2019).

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

Phytosociological table : Tab. 6; taxonomic nomenclature according to Bartolucci et al. (2018).

Notes : The Habitat identified is a remnant linear strip of cork oak vegetation, located in xeric conditions of the coastal area of south-west Sicily. The phytocoenosis has been assigned to Genisto aristatae-Quercetum suberis pistacietosum lentisci, which is differentiated from the subassociation typicum by the absence of Genista aristata (Marino et al. 2012) and the frequency of thermophilous species (Brullo et al. 2008).

It is the last vestiges of a Quercus suber forest (Fig. 8) that historically covered this area (Stieler 1880) which is named in Sicilian dialect Suvarito (meaning the cork oak forest). Nowadays, the formation is within a large tourist resort which, indirectly, has contributed protecting it. However, the community should receive special attention as it is located outside the Natura 2000 network sites.
