Corsican Pine (Pinus laricio Poiret) Stand Management: Medium and Long Lasting Effects of Thinning on Biomass Growth
2018
Originally published in Forests: Picchio R, Venanzi R, Latterini F, Marchi E, Laschi A, Lo Monaco A (2018). Corsican pine (Pinus laricio Poiret) stand management: medium and long lasting effects of thinning on biomass growth. Forests 9 (5), article number 257, p. 1-17 (open access) DOI: 10.3390/f9050257 This article can be downloaded at: https://www.mdpi.com/1999-4907/9/5/257 Abstract With the aim of acquiring better comprehension of the ecological and productive aspects of the management of pine forests, we monitored logging damage and evaluated the effects of thinning on stand growth 20 years after the treatment in a Pinus laricio Poiret stand in central Italy. The objectives of the p…
Early response ofQuercus roburseedlings to soil compaction following germination
2018
Logging operations using heavy machinery effect changes in soil characteristics due to compaction; such conditions can negatively influence seedling development. In stands managed on the basis of close-to-nature silviculture or continuous cover forestry, successful establishment of natural regeneration after logging is important to ensure the proper functioning of a forest ecosystem, to promote soil recovery, and to prevent and mitigate land degradation processes (such as soil erosion, mudflow, waterlogging, and landslides) related to soil compaction and rutting. This work aimed to assess the early response of Quercus robur seedlings to soil compaction during the first 1.5 months after germ…
Forest Road Planning, Construction and Maintenance to Improve Forest Fire Fighting: a Review
2019
Forest roads play a key-role in fire fighting activities. In fact, all ground-based activities are strictly related to the presence of forest roads as access to fire edge. In spite of this important role, forest roads are often planned and built without considering their use in fire fighting, and this also occurs in literature, where few studies are dedicated to the importance of forest roads in fire fighting. A well-developed and well-maintained forest road network is the answer to different needs in fire management. The objective of this review is to clarify basic principles for obtaining efficient road network also for fire fighting, collecting, defining and resuming the main roles, the …
The decline of the cork oak growing in Sicily is accompanied by the loss of the functions proper to agroforestry systems
2021
The cork oak is one of the most important tree species in the Mediterranean basin, where it covers more than 2 million hectares. Among evergreen oaks, Quercus suber stands out for the variety of cultural systems in which it has been successfully employed, including typical agroforestry systems. Accordingly, a wide range of ecosystem services may be associated to cork oak, including the preservation of biodiversity, carbon sequestration and forage production. In the Mediterranean, the cork oak represents a key species for many natural and seminatural landscapes and habitats, as well as playing a prominent role for the economic and social development of local communities. However, there is in…
Approssimazioni alla “leggenda del legno della Croce” nell'Occitania medievale
2019
La leggenda del legno della croce è una delle storie apocrife più significative del medioevo religioso. Essa è il risultato di un lungo processo di stratificazione di racconti e motivi leggendari, e risulta declinata in versioni plurime, più o meno scorciate e interpolate. Il presente contributo indaga la diffusione della storia del lignum crucis nel contesto occitano. La scelta non è casuale; appare, anzi, necessaria. In effetti, come spesso è avvenuto per quella che può essere considerata un’appendice alla cosiddetta «eccezione narrativa» occitana, lo studio della letteratura religiosa del Midi necessita ancora di nuovi spunti d’indagine, trasversali e comparativi. Di questo soffrono anch…
La leggerezza del lamellare. Una realizzazione e un progetto
2009
L’articolo si propone di mostrare le nuove frontiere del Legno Lamellare armato, sia attraverso una Chiesa a Gioia Tauro, (che rimane la prima applicazione naz. con questa tecnologia) sia attraverso un concorso appalto a Caltagirone, ove si configurano con più attenzione le cognizioni tecnologiche finalizzate alla snellezza e leggerezza dei materiali sino al loro stato limite. Sono queste due realizzazioni che propongono le prime Chiese “aperte” poiché vetrate a luce libera creando un unicum tra esterno ed interno. La prima opera si confronta con una copertura a membrana di circa 1000 mq che rimane appoggiata all’esterno dell’Aula Cultuale, il cui filtro vetrato si pone a mediazione con l’a…
LE CHIESE IN LEGNO DELLA LITUANIA - WOODEN CHURCHES OF LITHUANIA
2017
Lithuania have a great variety of wooden architec- tures, among which the churches emerge for their quality and construction characters, prevailing the use of local materials. The strong link between architecture and the uncontaminated nature of places defines the identity of architectures, so that they sometimes appear almost like a large wooden sculpture, carved in a unique piece. The meticulous knowledge of the buildings has created an atlas of construction techniques, proposing itself as a tool for the conservation and preservation of refined building heritage; the atlas is divided according to themes as wood species, processing methods, construc- tion phases, mutual relationship betwee…
Architettura e lavoratori del legno: alcune intersezioni e intrecci professionali nella Sicilia d'età moderna
2012
Il contributo individua e analizza intersezioni e intrecci professionali tra lavoratori del legno e architetti nell'architettura siciliana d'età moderna. In questo contesto e alla luce dei documenti rintracciati è possibile ricostruire traiettorie professionali che dal mondo della lavorazione del legno si estendono all'architettura: la presente ricerca ne indica casi significativi.
