Risultato della ricerca: Otherpeer review


In spite of the widespread use of the term “fast-growing species” referred to forest tree species used for biomassproduction, there are currently no definite references for defining the aforementioned species. It should be alsoconsidered that the term is used not only in articles and technical papers, but also in texts that are applicativeand/or represent reference standards such as, for example, the measures of Rural Development Plans. A long-established definition by FAO (1967), but with reference to the developing countries, reports: “Fast growing species are considered as those capable of a mean annual increment of at least 10 cubic meters per hectare”. In the meantime, since this definition was published, many other definitions have emerged including “fast growing high yelding” (FGHY), “Short Rotation Forestry” (SRF), “Short Rotation Coppice” (SRC). Naturally, fast growing species indicated for large areas of the planet, for example developing countries, that include wide desert areas and tropical and subtropical areas where the choice and response of usable species is clearly different, resulting in generic and misleading indications.Even for Italy, which has a considerable environmental heterogeneity, the indication of fast growing species is generic, if at least the area of use is not specified. First of all, the Authors made an assessment of the definitions and meanings used up to now in the world to indicate the fast growing species. A nationwide detailed assessment of the works referring to fastgrowing species was then carried out to identify, if indicated, the productivity thresholds. Finally, a detailedassessment was carried out for the Sicilian territory, making an analysis of the literature and unpublished data on the productivity of the different tree species, identifying those that can be considered among the “fast growing species”.Among the investigated species, eucalypts have confirmed to be the most promising trees for the regional context, but there are a number of critical issues that emerged from mistakes often made in the past. There is also the lack of experimentation conducted with modern criteria, and with this the need to deeply revise, in order to establish new afforestation plantings, the planting techniques, the choice of species/clones, etc., adopted in the past afforestations, which had been establish to increase the forest cover of the island.
