Il manuale si colloca nell’ambito dei progetti LIFE17 NAT/IT/000565 CALLIOPE (Coastal dune hAbitats, subLittoraL sandbanks, marine reefs: cOnservation, Protection, and thrEats Mitigation) e LIFE16 NAT/IT/000589 REDUNE - (REstoration of DUNE habitats in Natura 2000 sites of the Veneto coast) e come capitalizzazione delle azioni del progetto LIFE10 NAT/IT/000262 MAESTRALE (Azioni MirAtE al ripriSTino e alla conservazione degli habitat dunali e RetrodunAli in moLisE), tutti cofinanziati dal Programma LIFE, strumento dell'Unione Europea per la salvaguardia dell'ambiente che sostiene azioni a favore della natura negli Stati membri. I progetti propongono il ripristino/recupero di ambienti dunali mediante produzione e impianto di essenze vegetali locali, prodotte a partire da semi raccolti in campo da popolazioni vegetali adeguate dal punto di vista genetico, fisiologico e sanitario, al fine di tutelare e valorizzare la biodiversità delle aree costiere. Il manuale rappresenta una sintesi delle esperienze di produzione vivaistica delle principali specie dunali propagate all’interno dei progetti LIFE CALLIOPE, LIFE REDUNE e LIFE MAESTRALE con lo scopo di fornire informazioni tecnico-pratiche per una produzione efficiente e facilmente replicabile anche in altri contesti e progetti di ripristino/recupero ambientale, in cui è di fondamentale importanza disporre di materiale nativo caratterizzato da una elevata variabilità genetica. Questa, infatti, garantisce una migliore adattabilità, consentendo di massimizzare le probabilità di successo dell’intervento, e contribuisce alla creazione di habitat stabili con elevato valore naturalistico. Il manuale è rivolto a tecnici delle banche del germoplasma, vivaisti e addetti ai lavori in ambito istituzionale e le indicazioni fornite riguardano la fase di raccolta dei semi, la loro conservazione fino al momento del loro utilizzo e i successivi trattamenti in grado di massimizzare la germinazione e la produzione di nuove piante, nel rispetto delle procedure e degli standard nazionali e internazionali (ENSCONET, http://ensconet.maich.gr/Download.htm; Royal Botanic Gardens Kew 2021, https://data.kew.org/sid/).

: Italy is one of the European countries most affected by biological invasions. In this study, we focused on the impact of Acacia saligna, an Australian invasive plant species, on the coastal ecosystem’s ecology and biodiversity along the sandy coasts of Molise (southern Italy). We analyzed data from 61 vegetation plots recorded in coastal pine forest and Mediterranean scrub habitats of Molise throughout the preparatory actions of the “LIFE Maestrale” project (NAT/IT/000262). In order to study the ecological impact of Acacia saligna comparing invaded and non-invaded areas, we first assigned the Ellenberg’s indicator values to each plant species, which were then used to relate the presence of Acacia saligna with ecological characteristics of sites through a generalized linear model (GLM). Our results showed a significant positive relationship between the presence of Acacia saligna and high levels of soil nutrients and, on the contrary, a negative relationship with the presence of mesophilic species, which are typical of the community interest habitats of pine forest (2270*). The use of ecological indicators is effective to pinpoint the ecological effects of biological invasions, as well as to evaluate habitat conservation state and to identify vulnerable native species.

... Seeds were collected from the greatest possible number of individuals, within the limits of numerical consistency of populations (ENSCONET, 2009). Dune species, except in a few cases (e.g., Convolvulus soldanella), do not require special nursery treatments to break seed dormancy, but special attention must be paid to the choice of sowing period (which for most species is the autumn equinox (September); de Francesco et al., 2021). Individual plants were grown from seed, raised in pots and planted out in the field once they have reached the mature stage, i.e., at the age of one or two years. ...

... Selvi & Bigazzi (Farris et al., 2013) typical of fixed coastal dunes with herbaceous vegetation (grey dunes -HD 2130*) and invades coastal dunes with Juniperus spp (HD 2250*) Acunto et al., 2017). Through nitrogenfixation, A. saligna thickets promote the establishment of ruderal and nitrophilous species, simplifying and homogenising native plant communities (Caruso, 2012;Calabrese et al., 2017). ...

... On the contrary, in MBS the NH 4 + -N content had not recovered and N tot was slightly (not significantly) lower than in control, in the meantime nitrate N content, as well as N mineralization and nitrification, increased suggesting that MBS soil was losing N. The N loss probably did not occur in MBSA due to intense post-fire colonization by A. saligna, which can naturally fix N, so reducing the loss by leaching and could N-enrich the soil thanks to its symbiotic N-fixing bacteria (Slingsby et al., 2017;Yelenik et al., 2007). However, it has to be underlined that this apparent positive effect on soil N conservation by the invasive A. saligna could favor the establishment of nitro-ruderal species potentially leading to negative effects on native species, as recently found in similar habitat by Calabrese et al. (2017) and Lazzaro et al. (2020). The fire passage and subsequent vegetation colonization can change the intensity of seasonal fluctuations in soil climate conditions which are the main factor influencing microbial activity related to the nitrogen cycle in the Mediterranean area (Rutigliano et al., 2009). ...
