Which are Southern Italy’s fastest growing tree species? Lessons from the past for future perspectives, with a special focus on Sicily
2020
Fast growing tree species can generate high wood production in a short time frame. However, maximum productivity is dependent on environmental and management conditions as well as intrinsic plant traits. Within this framework, our research was into tree species with the highest Mean Annual Increments (MAIs) in southern Italy, particularly in Sicily. Eucalyptus spp., Acacia saligna (Labill.) H. L. Wendl., Ailanthus altissima Mill. (Swingle), Pinus halepensis Mill. (including Pinus brutia Ten.), Pinus canariensis C.Sm. and Pinus radiata D. Don. were identified. In particularly suitable conditions, the MAI of eucalypt coppices ranged from 8 to 12 m3 ha-1, and from 13 to 19 m3 ha-1, in Eucalypt…
Le principali specie arboree esotiche invasive e le categorie forestali più vulnerabili alla loro invasione nel territorio italiano
2022
In Italia, come in gran parte d’Europa, sono state introdotte numerose specie arboree esotiche che, in alcuni casi, si sono diffuse al di fuori delle aree di impianto e si sono naturalizzate, causando impatti alla biodiversità e al paesaggio. Studi recenti hanno definito la distribuzione degli alberi esotici invasivi in diversi habitat naturali e semi-naturali a scala nazionale. Sarebbe però utile soffermarsi sulla loro distribuzione tra categorie forestali, unità di classificazione dei boschi utili alla loro gestione. In questo lavoro sono state identificate le categorie forestali attualmente o potenzialmente più soggette all’invasione da parte delle specie arboree esotiche invasive, con l…
Plant landscape and phytodiversity in the archeological area of Segesta (NW Sicily)
2018
In the system of Sicilian archaeological parks, the area of Segesta - an ancient city of western Sicily referring to the Carthaginian eparchy, - represents, together with Selinunte, Erice and Mothia, another integrated hotspot of biodiversity and archeaology. The current plant landscape is strongly influenced by a millenary anthropic transformation. There are no residual expressions of the original plant covering that, with reference to the environmental potential of the area, can be traced back to the evergreen Mediterranean forest dominated by Quercus ilex, presently only sporadically occurring in the area of the ruins, together with other species related to associations and upper syntaxa…
