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…
The use of species in plantations: renaturalisation and reforestation in Sicily
2017
Afforestation and reforestation activities in Sicily have been widespread in the last century, in order to increase the forest cover that was seriously reduced in the former centuries. Notwithstanding this, Sicily is still characterized by only the 12% of the regional surface covered by woods and forest. The reforestation in the last century was carried out using conifers and eucalypts, just in order to ensure a quick protection of slopes and pastureland, coping diffuse erosion events, and those intervention had a remarkable success. Nowadays, the target of enlarging the forest areas in the island is still compulsive, but the use of species, considering the actual knowledge and nature consc…
I patriarchi verdi dei Monti Sicani
2016
Gli alberi vetusti costituiscono un segno della capacità e plasticità di adattamento di alcune specie ma sono anche spesso frutto del caso o di una considerazione particolare da parte di alcune comunità locali rispetto ad alcune piante. Sui Monti Sicani, situati nel settore centro-occidentale della Sicilia, si rileva la presenza di numerosi alberi monumentali, la cui conservazione è stata assicurata, nonostante le trasformazioni del paesaggio avvenute nel corso di un lunghissimo periodo, dalla positiva influenza delle conoscenze, tradizioni e buone pratiche delle popolazioni locali (De Gregorio, 2008). Tuttavia, ad eccezione del censimento dei grandi alberi di Sicilia (Schicchi e Raimondo, …

Resilienza delle foreste Mediterranee ai cambiamenti climatici - Guida al progetto [Resilience of Mediterranean forests to climate change – Project g…
2017
The overall objective of the project LIFE11+ ENV/IT/000215 RESILFORMED – Resilience of Mediterranean forests to climate change is to preserve the forest systems from the risks due to climate change, through naturalization processes, increased biodiversity and improved responsiveness, in the recovery process, coming from destabilizing events. The specific objective is to implement a regional forest policy able to increase resilience capacity of Sicilian forests, improving their ecosystem capacity and fostering the biodiversity preservation. The project has proposed to pursue five concrete results: 1) drafting guidelines for effective Mediterranean forest management with respect to climate ch…
Attacks of Rhynchophorus ferrugineus on natural specimens of dwarf fan palm Chamaerops humilis in Sicily.
2012
The red palm weevil Rhynchophorus ferrugineus was recently introduced into Europe where it has destroyed many Phoenix canariensis palms. This weevil attacks different species of palms in different countries, mainly cultivated date palms (Phoenix dactylifera) in Egypt and cultivated Canary palms (Phoenix canariensis) in Europe. In Europe, sporadic attacks of the weevil to native dwarf fan palm (Chamaerops humilis) have been reported. The current paper reports attacks of R. ferrugineus on dwarf fan palms in natural environments of Sicily. This insect represents an important threat to dwarf palms and to the complex ecosystem where they live.
The agricultural heritage of Lampedusa (Pelagie Archipelago, South Italy) and its key role for cultivar and wildlife conservation
2011
As occurred on many other little Mediterranean islands, agricultural activity at Lampedusa (Strait of Sicily) underwent a very strong decline in terms of surface area during the second half of the last century. In particular, cereal crops have ceased and horticulture is disappearing, while vineyards still occupy a reduced area but are quickly vanishing and currently survive thanks to a small number of old farmers. Here are presented the results of a research carried out by interviewing seven farmers in order to study not only the techniques and the germplasm used in local viticulture, but also the final use of grapes and an evaluation on the connection between traditional farming and agro-e…
