In the last 60 years the development of the vegetation became evident along some portions of the Grand Cone. This process is facilitated by the upslope expansion of the Genista aetnensis (Biv.) DC., a plant endemic of the Mt. Etna (Sicily) and of Eastern Sardinia, which has been imported to Mt. Vesuvio in 1906 as part of a reforestation program of the Vesuvius slopes. Vesuvio National Park, within the MED project For Climadapt, is conducting a multidisciplinary research program aiming at evaluating the effect of the G. aetnensis invasion of the Vesuvius Grand Cone, both at landscape and ecosystem level, also in light of current and predicted climatic changes. An intensive field investigation has been designed to explore the eco-hydrological conditions facilitating the expansion of the G. aetnensis. Plant species and soils have been collected both underneath and outside the cover of G. aetnensis canopies to gather relevant information about the interaction of the G. aetnensis with the other species as well as to explore the small scale spatial gradients of soil fertility induced by the G. aetnensis. Two permanent stations have been installed to monitor the differences in soil water content, soil temperature and air temperature between inside and outside the canopy cover. The collected data evidence that G. aetnensis tends to create an island of fertility by increasing the organic matter content in the soil and improving the soil water retention properties. Moreover, the G. aetnensis mitigates the daily soil temperature excursions, reducing the exposure of seeds to extremely high temperature values, particularly during the growing season, and the direct soil evaporation loss. These results suggest that the invasion of G. aetnensis can promote alternative successional trajectories that may dramatically affects vegetation dynamics. Further studies are needed to identity specific management practices that can limit the spread and impact of this species.

Wildfire promotes the invasion of Robinia pseudoacacia in the unmanaged Mediterranean Castanea sativa coppice forests / Luigi Saulino in Frontiers in forests and global change, 6 (2023) 

Public Citation [article]  inFrontiers in forests and global change > 6 (2023) . - 1177551 Titre : Wildfire promotes the invasion of Robinia pseudoacacia in the unmanaged Mediterranean Castanea sativa coppice forests Type de document : Imprimé Auteurs : Luigi Saulino ; Angelo Rita ; Adriano Stinca ; Greta Liuzzi ; Roberto Silvestro ; S. Rossi ; Antonio Saracino Année de publication : 2023 Article en page(s) : 1177551 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : In the Mediterranean region of southern Europe, Castanea sativa Mill. (Castanea) coppice stands are being invaded by non-native pioneer tree species due to recurrent coppicing and wildfire disturbances. There is a need to control the spread of non-native tree species in Castanea coppices due to their pivotal socio-economic role, however, to facilitate this, further research into invasive strategies and their interactions with disturbances is required. The non-native Robinia pseudoacacia L. (Robinia) has widely colonized the overaged and unmanaged Castanea coppice forests in Vesuvius National Park, which were disturbed by the low-severity fires in the summer of 2017. Here, we aimed to assess the functional traits conferring a competitive advantage to the Robinia over Castanea and the changes in spatial stand patterns driven by wildfire disturbance. To achieve this we assessed the spatial stem patterns, regeneration strategies, and conducted field-assessments and remote sensing of the spring leaf phenology of both Castanea and Robinia in five 300–600 m2 plots. After the 2017 wildfire, root suckers constituted 72% (±12) of the Robinia vegetative living sprouts and occurred up to a distance of 10 m from the adult parent trees under the canopy of the Castanea trees. NDVI-based estimates at the start of the growing season (sos) in Castanea occurred over a 7 day period, from DOY 118–124, increasing at a rate (rsp) of 0.10–0.16, in agreement with the field-based assessment of spring leaf phenology. In Robinia, the sos estimated at DOY 109 from the NDVI seasonal trajectory disagreed with the field-based observations, which started later than Castanea, after approximately DOY 133. Here, the high percentage cover (∼90%) of the understory species influenced NDVI-based estimates of Robinia leaf spring phenology. The results suggest that low-severity wildfires increased the invasiveness of Robinia, and that vegetative regeneration strategies, rather than earlier spring phenology, conferred a competitive advantage in the fire-disturbed Castanea coppice stands. The results thus suggest that appropriate management of invasive Robinia trees to conserve the continuous canopy cover of Castanea stands should guide nature-based solutions to control the spread of non-native tree species.
