I rimboschimenti di cedro dell’Atlante [Cedrus atlantica (Endl.) Manetti ex Carrière] in Sicilia
2012
Il cedro dell’Atlante [Cedrus atlantica (ENDL.) MANETTI EX CARRIÈRE], introdotto in Europa come pianta ornamentale, ha trovato largo impiego nei rimboschimenti in Francia, Spagna e Portogallo, mentre in Italia la sua diffusione è stata più recente e a oggi interessa oltre 2600 ettari, dimostrando ottime potenzialità, senza comportamenti invasivi. In Sicilia, benché poco diffusa, la specie sembra avere potenzialità di adattamento e di produzione interessanti. Il presente lavoro prende in considerazione 7 popolamenti di cedro dell'Atlante dislocati in ambiti diversi rappresentativi delle condizioni ambientali locali, compatibili con le esigenze ecologiche della specie, tra questi un rimboschi…
Les reboisements en cèdre de l’Atlas en Sicile
2013
Atlas cedar plantations in Sicily Atlas cedar (Cedrus atlantica) has been widely diffused in reforestation in Europe, particularly in France. In Italy, the Atlas cedar covers about 2600 ha. This paper examines 7 cedar plantations in Sicily, in the various typical condition of the island, evaluating their dendrometric characters in order to estimate productivity and growth capacity. The results show that this specie is both highly suitable for wood production, and has a landscape restoration role in difficult ecological conditions such as the Mediterranean mountain environment is. The stands production is comparable with the better results reported for the French plantations. Some cultivatio…
New Data on Native and Alien Vascular Flora of Sicily (Italy): New Findings and Updates
2023
In this paper, based on fieldwork and herbaria surveys, new data concerning the presence of 32 native and alien vascular species for Sicily (Italy) are provided. Among the native species, the occurrence of the following taxa is reported for the first time or confirmed after many decades of non-observation: Aira multiculmis, Arum maculatum, Carex flacca subsp. flacca, Mentha longifolia, Oxybasis chenopodioides, Najas minor and Xiphion junceum. Furthermore, we document the presence of three native species (Cornus mas, Juncus foliosus and Limonium avei) that, despite being repeatedly observed in Sicily and reported in the literature, are inexplicably omitted by the most recent authoritative ch…
