Le potenzialità del rimboschimento sono inquadrate in una prospettiva multifunzionale e sinergica che comprende le ricadute ambientali di questa attività anche in termini di assorbimento del carbonio atmosferico e potenziamento della biodiversità, oltre che di conservazione del suolo e recupero e riqualificazione di paesaggi degradati. L’obiettivo è delineare una strategia di lotta alla desertificazione applicabile a livello regionale, nel quadro degli strumenti programmatici e di governo del territorio rurale e fornire orientamenti tecnici per la progettazione dei rimboschimenti su terreni degradati 2008-12-31T23:00:00Z http://hdl.handle.net/2067/1902 Title: Deadwood in forest stands close to old-growthness under Mediterranean conditions in the Italian Peninsula Authors: Corona, Piermaria; Lombardi, Fabio; Chirici, Gherardo; Marchetti, Marco; Tognetti, Roberto; Lasserre, Bruno; Barbati, Anna; Ferrari, Barbara; Di Paolo, Silvia; Giuliarelli, Diego; Iovino, Francesco; Nicolaci, Antonino; Bianchi, Livio; Maltoni, Alberto; Travaglini, Davide Abstract: Considering that indicators of old-growth features can vary across the European ecoregions, this paper provides some results to identify the distinctive traits of old-growth forests in the Mediterranean ecoregion. Deadwood occurrence as indicator of naturalness is investigated in some remote forest areas that have developed in absence of anthropogenic disturbance over the past few decades. Eleven study sites across the Italian peninsula were elected and records of deadwood were carried out in 1-ha size plots. Deadwood volume, deadwood types and decay stages were inventoried in the selected sites. The amounts of deadwood indicate a large variability among the investigated forest stands: the total volume ranged between 2 and 143 m3ha-1, with an average of 60 m3ha-1. Lying deadwood is the most abundant component of deadwood in the investigated forests, due to the natural mortality occurring in the stands in relation to the processes established in the last decades. On the contrary, stumps are the less represented type of deadwood in almost all the study areas. All the decay classes are present in each study site. The amount of deadwood in Southern Europe, even if lower than that reported for North and Central European countries, could have a different meaning due to the faster decay occurring in Mediterranean forest ecosystems. For this reason, old-growth features and the characteristics of each indicator should be framed and referred to well-defined climatic and biogeographic contexts. Distinctively, under the conditions here investigated, three main deadwood features prove to characterize forest stands close to old-growthness: a ratio of dead to living wood not lower than 10%; lying deadwood much more abundant than the standing one; large range of deadwood size and decay classes across all the deadwood components. 2009-12-31T23:00:00Z http://hdl.handle.net/2067/1904 Title: The application of the ecosystem approach through sustainable forest management: an Italian case study. Authors: Barbati, Anna; Corona, Piermaria; Portoghesi, Luigi; Iovino, Francesco; Marchetti, Marco; Menguzzato, Giuliano Abstract: During the last decades adapting silvicultural systems to a changed society, increasingly aware of the multifunctional role of forests, was a much debated issue in Italy. Stemming from this discussion is the systemic silviculture concept, an adaptive forest management tool aimed at cultivating the forest as a self-organizing system and focusing on sustaining its functional efficiency as the best way to enhance forest multi-functionality. This concept has much connection with the Ecosystem Approach defined by the Convention on Biological Diversity as a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way. In the following a case study is presented where the principles of systemic silviculture are implemented in the management of private and common forest properties in the Serre mountains of the Calabria Region (Italy); relationships with the Ecosystem Approach principles are analyzed in order to evaluate to what extent systemic silviculture can be regarded as a means to bring the EA to the implementation level. 2009-12-31T23:00:00Z http://hdl.handle.net/2067/2213 Title: Stand structure attributes in potential Old-Growth Forests in the Apennines, Italy Authors: Calamini, Gianfranco; Maltoni, Alberto; Travaglini, Davide; Iovino, Francesco; Nicolaci, Antonino; Menguzzato, Giuliano; Corona, Piermaria; Ferrari, Barbara; Di Santo, Daniele; Chirici, Gherardo; Lombardi, Fabio Abstract: The aim of this paper is to provide early feedback on stand structure attributes in Italian Apennines forests that could be considered Old Growth Forests in the Mediterranean Eco-Region. Few data are nowadays available relating to this Region. 10 forest reserves across the Apennines were selected and a census of trees and structural parameters was conducted in permanent plots (0.16-1.0 ha), one plot for each selected forest stand. Dimensional and structural characters indicate a large variability among the investigated forest stands. The considered parameters are compared with those reported for other European countries. Old growth features and characteristics of each indicator should be revised and referred to the particular climatic and biogeographic context. The chosen forest study sites are to be considered old if related to common Apennine stands but, in some cases, their development stage is not so close to “truly” Old Growth Forest. Permanent plots allow future investigations on dynamic processes leading to real Old Growth Mediterranean Forests in Italian Apennines. 2010-12-31T23:00:00Z
