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/2067/2140 Title: Pianificazione ecologica dei sistemi forestali Authors: Corona, Piermaria; Barbati, Anna; Ferrari, Barbara; Portoghesi, Luigi Abstract: Questo testo didattico, focalizzato su piani e programmi deputati al governo delle superfici forestali a diversi livelli di scala nel nostro Paese, è orientato a presentare e discutere il ruolo degli strumenti di pianificazione forestale all’interno del più ampio scenario di strategie e norme per il governo del territorio intessuto dai piani di matrice urbanistico-territoriale e ambientale e dagli strumenti di valutazione ambientale integrata. Chiave di lettura della trattazione è l’applicazione di un approccio ecologico nelle varie fasi del processo di pianificazione. Esso si traduce nel ricorso a strumenti di indagine e di procedure valutative funzionali a: (i) mettere in luce opportunità e limiti da considerare nella gestione dei territori forestali al fine di garantire la durevolezza e riproducibilità dei beni e servizi da essi erogati, dalla scala locale a quella di paesaggio; ciò tenuto anche conto della varietà di regimi di protezione delle aree forestali applicati nel nostro Paese; (ii) garantire la sostenibilità ecologica delle trasformazioni territoriali e, dunque, anche la salvaguardia dei sistemi forestali, mediante strumenti specifici di valutazione e di tutela ambientale integrata. In relazione a ciò uno dei principali obiettivi didattici (e questo rappresenta una novità, almeno con riferimento al panorama della letteratura di settore in Italia) è il tentativo di integrare in un quadro organico e di lettura non eccessivamente specialistica i vari aspetti ecologici, normativo-procedurali e tecnico-gestionali coinvolti. 2010-12-31T23:00:00Z http://hdl.handle.net/2067/2153 Title: Risorse forestali e rischio di desertifcazione in Italia.

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/2067/1903 Title: Support of multispectral very high solution remotely sensed imagery for old-growth beech forest detection. Authors: Di Paolo, Silvia; Giuliarelli, Diego; Ferrari, Barbara; Barbati, Anna; Corona, Piermaria Abstract: In the Mediterranean basin human activity has modified landscapes for millennia,nevertheless there are few remote forest areas relatively untouched long enough from direct anthropogenic disturbance to develop old-growth attributes. The aim of this note is to assess the potential of QuickBird (QB) satellite multispectral imagery for detecting old-growth forest stands, considering as case study a Mediterranean beech forest in central Italy. The segmentation-based analysis of QB image proved to be a promising tool to detect scaledependent pattern of forest structural heterogeneity. Values of remotely sensed attributes are compared in old-growth and not-old-growth stands: the statistical analysis showed that oldgrowthness is associated to the variability of multispectral reflectance from the image objects (polygons). Green band variability, notably, expressed by Ratio_band_2 has proven to be helpful for predicting old-growthness. 2009-12-31T23:00:00Z http://hdl.handle.net/2067/1905 Title: Proposta metodologica per l'inventario su vasta scala fuori foresta. Authors: Corona, Piermaria; Chiriacò, Maria Vincenza; Ferrari, Barbara; Salvati, Riccardo; Marchetti, Marco; Lasserre, Bruno Abstract: Methodological proposal for large-scale inventory of trees outside forests Trees outside forests (TOF) are all those forest trees or group of trees scattered within rural and urbanized areas and not classified under forest. The importance of TOF is known as a source of energy for domestic use, soil and wind protection, biodiversity conservation, atmospheric CO2 sequestration, etc. The aim of this note is to outline a survey methodology to assess TOF on large territories, exploiting the first phase of the large-scale multiphase forest inventories. The protocol was tested in various landscapes in Italy, for a total inventoried land of 3533 km2. In the test areas TOF proved to stock 12,1 Mg C km-2, on average. 2008-12-31T23:00:00Z http://hdl.handle.net/2067/2111 Title: Monitoring and assessing old-growth forest stands by plot sampling Authors: Corona, Piermaria; Blasi, Carlo; Chirici, Gherardo; Facioni, Laura; Fattorini, Lorenzo; Ferrari, Barbara Abstract: Forest inventories are evolving towards multipurpose resource surveys, broadening their scope by including additional topics such as biodiversity issues. Surprisingly, few quantitative surveys have been devoted to old-growth forests, even if they constitute the most acknowledged forest biodiversity icons. In this framework, the use of probabilistic sampling may provide an effective as well as rigorous support for monitoring and assessing old-growth forests. To this purpose, the present paper proposes a two-phase sampling scheme. In the first phase, a coarse survey of few floristic and stand structural attributes is carried out by means of small plots systematically placed on the study area. Subsequently, in the second phase, a fine assessment of a large number of ecological attributes is performed on a subset of enlarged plots selected among the first-phase ones by means of simple random sampling without replacement. The proposed sampling scheme is implemented for monitoring and assessing the old forests of Cilento National Park (southern Italy). Results and comments are provided as an exemplicative case study.

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
