IoT monitoring of urban tree ecosystem services: Possibilities and challenges
2020
Urban green infrastructure plays an increasingly significant role in sustainable urban development planning as it provides important regulating and cultural ecosystem services. Monitoring of such dynamic and complex systems requires technological solutions which provide easy data collection, processing, and utilization at affordable costs. To meet these challenges a pilot study was conducted using a network of wireless, low cost, and multiparameter monitoring devices, which operate using Internet of Things (IoT) technology, to provide real-time monitoring of regulatory ecosystem services in the form of meaningful indicators for both human health and environmental policies. The pilot study w…
Study of energetic properties of different tree organs in six Olea europaea L. cultivars
2021
AbstractPruning is an important horticultural practice for the management of olive orchards (Olea europaea L.) that generates a considerable amount of residues every year. Olive orchards are increasingly expanding beyond the Mediterranean Basin to new growing Countries (Australia, California, Argentina, Chile and Uruguay) and this will certainly lead to larger availability of pruning material. Currently, the interest in use of olive tree pruning residues for energy purposes is increasing but unfortunately, the information on the differences among organs of the tree, in terms of calorific value and ash content, is scarce. Another unknown aspect is the effect of cultivar vigour on dry matter …
Traditional use of wood in Sicily
2020
The results of a multidisciplinary survey on the use of wood in Sicily are presented here. This research, based on a thorough review of the information available from numerous sources, mostly related to Socio-economic Sciences and Humanities, sheds light on the lasting, widespread and diversified use of many tens of woody species - native and cultivated - growing on the island. This work represents an initial contribution to a topic largely overlooked the national and regional literature concerning forest sciences and wood technology. Contrariwise, the very precise information available on the specific uses of wood from certain Sicilian woody species clearly testifies to the profound knowle…
La certificazione PEFC di prodotti forestali non legnosi: il sughero in Sicilia.
2019
La certificazione PEFC (Programme for the Endorsement of Forest Certification) è un sistema di valutazione della sostenibilità della gestitone forestale. Il sistema PEFC opera lungo tutta la catena di approvvigionamento forestale promuovendo le buone pratiche forestali e garantendo che il legname e i prodotti forestali non legnosi siano prodotti nel rispetto dei criteri degli standard ambientali e sociali. Numerosi studi dimostrano che la certificazione forestale, attraverso una maggiore consapevolezza di gestitone ambientale, determina una maggiore richiesta dei prodotti sul mercato. Nell'area mediterranea sono presenti circa 2,3 milioni di ettari di sughereta strettamente legati alla pres…
Buone prassi per la riduzione degli impatti durante le operazioni di esbosco
2022
La pubblicazione affronta varie tematiche inerenti l'impiego di macchine e attrezzature altamente meccanizzate per l'esbosco dei prodotti legnosi e analizza in dettaglio le buone prassi raccomandate per ridurre gli impatti al suolo di macchine che sono sempre più potenti e pesanti. Risultati conclusivi del progetto SKIDDFORW
Impact of wheeled and tracked tractors on soil physical properties in a mixed conifer stand
2016
Abstract: Damage to forest soil caused by vehicle traffic mainly consists of soil compaction, displacement, and rut formation. Severity of the damage depends on vehicle mass, weight of the carried loads, ground morphology, and soil properties, such as moisture. This paper investigates the impacts of two types of vehicles (tracked or wheeled tractor), traffic intensities (one or five skidding cycles) and soil moisture (24% or 13% by weight) on compaction of a loam textured soil in a mixed conifer stand of central Italy. Changes in porosity, bulk density, shear and penetration resistances were analyzed. The latter three parameters were significantly higher in the trafficked soil portions than…
Gli uccelli delle isole circumsiciliane
2015
Gli autori sintetizzano tutte le informazioni bibliografiche e inedite sulle specie che sino al 30 agosto 2015 sono state contattate almeno una volta nelle 14 isole circumsiciliane (Eolie, Ustica, Egadi, Pantelleria e Pelagie), confrontando alla fine la lista complessiva con quella delle isole Maltesi. In totale sono ad oggi note 434 specie (isole Maltesi incluse); molte di esse hanno mostrato nel corso dei secoli una notevole capacità di colonizzazione, fluttuando nel tempo o addirittura estinguendosi e ricolonizzando alcune isole. Questi piccoli territori in mezzo al mare rappresentano ottimi siti di controllo dell’andamento delle migrazioni nel corso dei decenni; alcune specie hanno chia…
Impact Assessment of Skidding Extraction: Effects on Physical and Chemical Properties of Forest Soils and on Maple Seedling Growing along the Skid Tr…
2019
Several studies investigated soil disturbances caused on skid trails by forest logging. However, there is still a lack of knowledge about the severity and the distance of disturbances along both sides from the trails. The aims of this study were: i) to investigate the changes in physical and chemical properties of soil along the sides of skidding trails
Use of Battery- vs. Petrol-Powered Chainsaws in Forestry: Comparing Performances on Cutting Time
2022
The use of battery tools is very common in many fields of work. In fact, the electric engine and batteries have several advantages over traditional endothermic engines, including low emissions, in terms of pollutants, vibration and noise. In this context, the chainsaw market started producing electric models powered by batteries. These machines can be useful in forestry, but information on their performance is scarce. The aim of this work was to compare the performance, in terms of cutting times, of three Stihl chainsaw models: the MS 220C-B (battery powered), and the MS 201 C-M and MS 261 C-M (both petrol powered). The study was carried out on five different wood species, also taking into …
A methodological approach exploiting modern techniques for forest road network planning
2016
A well-developed road network allows all forest activities, including wood harvesting, firefighting and recreational activities. However, forest road construction and maintenance involve economic and environmental costs. For these reasons, forest road network planning is a fundamental phase of forest management, maximising the benefits and reducing costs and impacts. Thanks to modern technologies in data collection both for terrestrial and forest characteristics, new methods and tools have been developed to improve and facilitate road planning. The aim of this study was the development of a Decision Support System for helping managers during forest road network planning, exploiting Multi-Cr…
