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…

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.

Jacopo Salemi: un modello ligneo per il monastero di San Nicolò l'Arena a Catania

2014

Jacopo Salemi, architetto e scultore proveniente dalla città di Castrogiovanni, il giorno 8 novembre 1563 a Catania, sottoscrive un contratto con la congregazione dei monaci benedettini per la costruzione di un modello in legno della chiesa San Nicolò l’Arena che si stava costruendo dal 1558 sul confine ovest della città. Il documento che regola l’incarico tra Salemi e i benedettini è datato 24 febbraio 1564 ed è custodito presso l’Archivio di Stato di Catania; tale documento rivela che il modello realizzato da Salemi sarebbe stato valutato da due esperti incaricati provenienti dalla città di Messina. Le ragioni di una tale commissione potrebbe essere stata connessa alla necessità di verifi…
