Forest Sharing® as an Innovative Facility for Sustainable Forest Management of Fragmented Forest Properties: First Results of Its Implementation
2023
The forestry sector in Italy and throughout Europe is going through a critical period due to ongoing natural and anthropological processes, such as climate change and the abandonment of rural areas. These processes lead to a constant fragmentation of properties in small forest parcels, with direct impacts on management capacity. In this framework, new sustainable forest management methods are being tested and are shown to be good practices to oppose the decline of forest ecosystems. Their innovative aspects concern the introduction of a form of shared and circular economy, where management is built on the process, rather than on the product. Their technical activities are based on precision…

Advanced earth observation approach for multiscale forest ecosystem services modeling and mapping (MIMOSE)
2014
In the last decade ecosystem services (ES) have been proposed as a method for quantifying the multifunctional role of forest ecosystems. Their spatial distribution on large areas is frequently limited by the lack of information, because field data collection with traditional methods requires much effort in terms of time and cost. In this contribution we propose a methodology (namely, MultIscale Mapping Of ecoSystem servicEs - MIMOSE) based on the integration of remotely sensed images and field observation to produce a wall-to-wall geodatabase of forest parcels accompanied with several information useful as a basis for future trade-off analysis of different ES. Here, we present the applicat…
The effects of post-pasture woody plant colonization on soil and aboveground litter carbon and nitrogen along a bioclimatic transect.
2013
Abstract: We investigated the effects of woody plant colonization of abandoned pastures on soil and litter organic carbon (C) stocks and nitrogen (N) content along a bioclimatic transect in a semi-arid environment (Sicily, Italy). Soil samples were taken in three successional stages (grazed pasture, shrubland, forest) within each of three bioclimates (supramediterranean - “supra”, mesomediterranean - “meso”, thermomediterranean - “thermo”). Organic C and N in litter and soil (0-10 cm and 10-30 cm depth) were determined, as well as soil bulk density. Especially at 0-10 cm depth, changes in C and N contents along successional stages differed among bioclimates. Soil organic carbon (SOC) stock …
Gli effetti dei trattamenti selvicolturali sulla dinamica delle cenosi fungine
2008
Gli ecosistemi forestali della Sicilia sono caratterizzati da un elevato livello di diversità. In particolare i funghi lignicoli, patogeni e saprofiti, sono numericamente ben rappresentati ed esprimono una diversità funzionale colonizzando varie tipologie di materiale legnoso. Per le ricerche effettuate all’interno degli ecosistemi forestali, naturali ed artificiali, si è fatto riferimento alla metodologia adottata a livello nazionale dal Gruppo di Interesse Scientifico per la Micologia della Società Botanica Italiana. In questo contributo la diversità dei funghi lignicoli viene messa in relazione con la forma di governo e di gestione selvicolturale. Viene inoltre sottolineata l’influenza d…
A casual alien plant new to Mediterranean Europe: Ceiba speciosa (Malvaceae) in the suburban area of Palermo (NW Sicily, Italy)
2014
The abiotic and biotic characteristics of the first sites where floss silk tree behaves as a casual alien plant in the Mediterranean Europe are described. The species was probably first planted in botanical gardens of southern France few decades before mid XIX century. It was introduced in Palermo in 1896, a city which appears to match very well its climatic requirements. According to the available information on its biology and ecology in both its original and secondary range, the floss silk tree should not become an invasive alien plant in the Mediterranean. Nevertheless, several gaps need to be filled in order to increase our understanding of future trends of Ceiba speciosa in southern E…
The green granary of the Empire? Insights into olive agroforestry in Sicily (Italy) from the Roman past and the present
2023
Groves with ancient olive trees (Olea europaea L.) could be considered remnants of old agroforestry systems. Anything but static, these agro-ecosystems have undergone drastic transformational processes in Mediterranean countries, where abandonment or intensification have been observed far more than continuity, expansion or renaissance, leading to environmental degradation of rural areas. Starting from this assumption and inspired by historical ecology and historical geography, we consider centuries-old olive trees as living archives of human-nature interactions and are thus proxies of past agroforestry. Our aim is to better understand what has driven dynamics of change and persistence, happ…
Riconoscere e interpretare i paesaggi dei sistemi arborei tradizionali: i casi studio della maremma laziale e del monte Etna
2014
Starting from the Sixteen’s of the past century it occurred in Italy, although with differences among the plane areas and the marginal hill or mountain ones, a deep transformation in the physiognomy of arboriculture following new architecture and new management criteria developed for an industrialized agriculture. Indeed, some traditional agricultural landscapes have maintained their functional and structural complexity. The present study refers to an interdisciplinary methodology developed for identifying and mapping the traditional landscapes through an approach based on multitemporal analysis of land use maps, visualization of land use persistences and evaluation of their representativen…
Diversità paesaggistica e multifunzionalità dei sistemi agro-forestali dell’Etna
2010
Il paesaggio dell’Etna è un complesso di paesaggi ricchi e diversissimi grazie alla estrema variazione di quote ed esposizioni che da sempre condizionano attività umane e crescita degli organismi; il cono vulcanico etneo rappresenta il principale rilievo e contemporaneamente la formazione geologica più giovane dell’Isola. Tra la fascia basale, maggiormente soggetta ad intesificazioni colturali e quella montana a carattere forestale domina la fascia pedemontana caratterizzata da un’importante valenza paesaggistica e biologica. Allo scopo di prevenire la degradazione o peggio ancora la perdita di questi particolari agroecosistemi è necessario colmare le lacune conoscitive sulla classificazion…
New tree monitoring systems: from Industry 4.0 to Nature 4.0
2019
This is the accepted version of the article "New tree monitoring systems: from Industry 4.0 to Nature 4.0" published as final paper in Annals of Silvicultural Research Volume 43, Issue 2, 2019, Pages 84-88, http://dx.doi.org/10.12899/asr-1847 Abstract - Recently, Internet of Things (IoT) technologies have grown rapidly and represent now a unique opportunity to improve our environmental monitoring capabilities at extremely low costs. IoT is a new system of thinking in which objects, animals or people are equipped with unique identifiers and transfer data to a network without requiring human-to-human or human-to-computer interaction. IoT has evolved from the convergence of wirele…
