Effects of traditional forest management on carbon storage in a Mediterranean holm oak (Quercus ilex L.) coppice
2018
Abstract: In the last decade, there has been increased interest in measuring and modeling storage in the five forest carbon pools: the aboveground and belowground biomass (living biomass), the deadwood and litter (dead biomass), and the soil (soil organic matter). In this paper, we examined carbon storage in a holm oak coppice stand in the Madonie Mountains in Sicily (Italy), which is a typical case of managed coppice stands. Today, traditional coppice practices are only applied to a small number of forested areas in Sicily, such as the selected site, because of the decline in demand for wood and charcoal. The dendrometric parameters of the stands were recorded, and silvicultural indices we…
Mapping traditional cultural landscapes in the Mediterranean area using a combined multidisciplinary approach: Method and application to Mount Etna (…
2011
Traditional cultural landscapes (TCLs) are prominent in Mediterranean countries. The abundance of this landscape type, however, is not reflected by broad-scale inventories and mapping tools. The aim of this paper is to highlight the need for a multidisciplinary approach to landscape analysis, with special reference to the Mediterranean area. We propose an integrated method that combines deductive and inductive processes to define and map TCLs in a study area (Mount Etna, Sicily, Italy). We also develop a procedure to characterize the primary components of these landscapes as a reference to be used in cultural-landscape descriptions. For mapping purposes, three different scales of analysis w…
Resilience of Mediterranean Forests to Climate Change
2017
In the Mediterranean region, forests play a key role in the welfare of urban and rural peoples, by providing highly appreciated marketed goods as well as high value but nonmarket services. Anthropogenic climate change entails a significant impact on Mediterranean forests, such as the reduced species diversity, high density, pest, and diseases. In this chapter, we present the achievements of the project LIFE ResilForMed (Resilience of Mediterranean Forests to climate change), as Sicilian responds on adaptation and mitigation to climate change: (i) map of Sensitivity Forest Areas to desertification of the Sicilian region; (ii) list of bird indicators showing sensitivity to desertification in …
Comparing different methods to determine soil physical quality in a mediterranean forest and pasture land
2016
Soil physical quality (SPQ) can be assessed by different experimental methodologies and criteria and the optimal/critical values or ranges for SPQ indicators are still approximate. Sampling soils with minimal anthropic pressures should allow improvements in SPQ assessment. Different experimental methodologies and criteria were applied to sample a Mediterranean oak forest (Quercus ilex L.) and pasture land, in Sicily, with a varying degree of anthropic disturbance. Soil water retention was determined in the laboratory and the field, using the BEST (Beerkan Estimation of Soil Transfer parameters) procedure of soil hydraulic characterization. Capacity-based indicators, the S index, and locatio…
La complessità del paesaggio agrario del “giardino mediterraneo” a partire dalla tavola di Alesa
2014
The Mediterranean is characterized by landscapes as result from long and complex historical processes in a varied environment. An identification and clarification of the role of the “Mediterranean Garden” (MG) in the Traditional Mediterranean Landscape (TML) is necessary. The MG is often associated with numerous different agricultural landscapes, due to the long historical process that has led to their identification. This paper identifies the characteristics of the MG’s landscape, starting from a historical overview of Sicily. What emerges is the structural, compositional and functional character of these traditional landscapes and systems, which is complex, multipurpose and often with mix…
Restoration practices in Mediterranean habitats using native woody species
2017
Since the beginning of the XXI century, Legambiente (a national environmental association), supported by the University of Palermo, has launched several naturalization projects within three Sicilian nature reserves: 1)Isola di Lampedusa (Agrigento Province); 2)Macalube di Aragona (Agrigento Province); 3)Lago Sfondato (Caltanissetta Province). Interventions were carried out on bare lands and degraded sites where natural vegetation cover was almost completely disappeared. The main aim was to restore native habitats following the principles of ecological restoration. Accordingly, differently from the classical approach, consisting in the use of preparatory species, usually Pines, native shrubs…
Soil microbial diversity has an impact on plant diversity and safeguard

Diversity of microbial plant symbionts has an impact on plant diversity. Examples are given for Mediterranean species.
Sviluppo di modelli innovativi per il monitoraggio multiscala degli indicatori di servizi ecosistemici nelle foreste Mediterranee (Progetto MIMOSE).
2013
Gli ecosistemi, attraverso le loro funzioni, forniscono un ampio range di beni e servizi, che risultano fondamentali per il benessere dell’uomo. Questi vengono complessivamente definiti Servizi Ecosistemici (SE). I SE possono essere intesi come un flusso di valori verso la società, quale risultato dello stato e della quantità del capitale naturale disponibile. Il mantenimento degli stocks del capitale naturale può permettere di prevedere i flussi futuri dei SE, assicurando quindi il benessere dell’uomo per le generazioni future. Il progetto FIRB 2012 MIMOSE è finalizzato allo sviluppo di un approccio multiscala innovativo e all’implementazione di strumenti previsionali volti al monitoraggio…
Dinamiche dell’uso e delle coperture del suolo dell’ultimo mezzo secolo nel paesaggio forestale siciliano.
2014
Il lavoro è stato realizzato nell’ambito dell’Azione 3 del progetto LIFE11 ENV IT 215 “RESILienza al cambiamento climatico nelle FOReste MEDiterranee”. In particolare, è stato implementato un sistema di monitoraggio attraverso indagini diacroniche sui principali contesti territoriali pre-forestali e forestali della Sicilia. L’analisi è stata condotta a livello di paesaggio in sei distretti forestali, rappresentativi delle principali categorie forestali della regione, quali i Sicani, le Madonie, i Nebrodi, l’Etna, l’area del Calatino (Sicilia SO) e l’isola di Pantelleria. L’analisi condotta ha come obiettivo il cambiamento dell’uso e delle coperture del suolo avvenuti nel corso dell’ultimo s…
