New data on the distribution of the Annex I Habitats 3160, 7210* and 9320 are reported in this contribution. In detail, 24 new occurrences in Natura 2000 Sites are presented and 42 new cells in the EEA 10 km x 10 km Reference grid are added. The new data refer to Italy and in particular to the Administrative Regions Lombardy, Sardinia, and Sicily.

 3160 7210* 9320 biodiversity conservation 92/43/EEC Directive Italy vegetation Introduction

This is the third standardized contribution reporting records of new occurrences of Annex I Habitats in Europe. The data here presented have been compared to the results of the 4th Report ex-Art. 17 on Annex I Habitat Monitoring in Europe, delivered in 2019 and available on the Eionet Central Data Repository (Eionet, 2019). As usual, the related phytosociological relevés here reported will be archived in the Italian database "VegItaly" (Gigante et al. 2014; Landucci et al. 2012).

 Habitats Records

The single records including details and descriptions of the newly recorded habitats are hereafter listed. As standard reference for official sources and formats, the indications in Gigante et al. (2019) have been followed. A synthetic overview of the newly recorded occurrences is provided in Table 1. The maps have been created by using the open source QGIS Geographic Information System (QGIS.org 2020).

Phytosociological table: Table 2; taxonomic nomenclature according to Bartolucci et al. (2018) and Aleffi et al. (2015).

Notes: Relict Utricularia minor L. populations have been recently recorded for the "La Piuda", an extensive alkaline fen habitat (~115 ha) located few kilometres northwest the city of Mantua, in the central sector of the Po plain. Here, a series of small dystrophic pools (<5 m2) are scattered within a series of peat meadows dominated by Molinia caerulea (L.) Moench and Cladium mariscus (L.) Pohl (Biondi et al. 2009; Brusa et al. 2017). These species create a complex vegetation mosaic interspersed by dense pioneer stands of Rhynchospora alba (L.) Vahl. The system results largely fed by groundwater seepage and apparently it is hydrologically disconnected by the nearby Mincio River. Indeed, the water quality of the ponds is not compliant with the physical and chemical status of surface water bodies of the Po plain (Bolpagni et al. 2016). The reactive soluble phosphorous, for example, turned out to be always lower than the analytical detection limit (5 µg L-1, Bolpagni R., unpublished data). These peculiar chemical features offer the basal conditions for the maintenance of the U. minor communities and peatland mosses, mainly represented by Sphagnum contortum Schultz and Campylium stellatum (Hedw.) Lange & C.E.O. Jensen. Further, the local water oligotrophy guarantees the presence of species and vegetation of exceptional biogeographical value in the context of the Po plain, at an altitude of only 20 m a.s.l. The present report expands and reinforces the presence of the habitat 3160 in the Continental region in Italy, that was considered, so far, only marginal.

Phytosociological table: Table 3; taxonomic nomenclature according to Portale della Flora d’Italia (2019).

Notes: This new station was detected basing on the data concerning Cladium mariscus (L.) Pohl distribution reported in the online floristic database "Wikiplantbase" (Peruzzi et al. 2017). This is the second reported site of occurrence of this priority habitat for Sardinia Region, being the first one at Platamona lagoon (Gigante et al. 2019). The station is very close to the sea and in contact with psammophilous vegetation.

Phytosociological table: Tab. S1, S2, S3, S4, S5, S6 in Gianguzzi and Bazan (2019a). The online database “The Plant List” (2013) and the Euro+Med Plantbase (Euro+Med, 2006-2019) were used for taxa nomenclature.

Notes: Recent studies have paid attention to the forest communities dominated by Olea europaea L. var. sylvestris (Mill.) Lehr. in Sicily (Gianguzzi & Bazan, 2019a) and the Mediterranean area (Gianguzzi & Bazan, 2019b), highlighting some inconsistencies in the correct interpretation and distribution of habitat 9320. In fact, as shown by the map in Fig. 3, the data collected for the IV Report (Eionet, 2019) still showed clear gaps in the distribution of this habitat in Sicily and in the southern part of the Italian Peninsula. These gaps were partly attributable to the significant destruction of oleaster forest formations – especially in the coastal belt – largely replaced by agricultural systems and urbanized areas, and only surviving in limited and fragmentary forest patches. Olea europaea var. sylvestris is a typical element of maquis dominated by Pistacia lentiscus as well as by Euphorbia dendroides (see, e.g., Molinier 1954; Trinajstic 1973, 1984)]. The abandonment of agricultural use and the reduction of human disturbances (on scrublands) lead over time to the gradual development of oleaster-dominated forest formations (Gianguzzi et al. 2016). Recent phytosociological surveys carried out on a large scale in Sicily (Gianguzzi & Bazan, 2019a, 2019b), have highlighted a more widespread presence of habitat 9320 than expected, although in punctual and small areas. These forest formations – and therefore the habitat 9320 – show a large-scale distributive potential, in line with what has been highlighted in other areas of the Mediterranean (Fig. 3). Considering their peculiarity, a more precise location of the representative sites and mature consortia would be necessary to promote their conservation and to limit their further floristic and phytocenotic biodiversity loss and structural deterioration.
