The sculpture of Sant'Antonio Abate represents an interesting example of vernacular art, it is a devotional object celebrated and carried in procession in many villages of Tuscia. The poor documentation and the observations of technical and stylistic characteristics do not allow the placement of the artifact at a well-defined period. It is also necessary to know the materials used for its realization before the start of restoration operations. Preliminary diagnostic investigations have allowed to date by radiocarbon, the sculpture, which was carved on lime wood, in the second half of the fifteenth century. XRF analysis has identified White Lead, Titanium and Zinc, this last in the habit of the sculpture. XRF data’s interpretation is not so obvious because all the investigated repainted areas did not show strong compositional differences from the original ones. Re-depicting were assessed after stratigraphic sections. The obtained data support exploitation of the cultural heritage in the museum and are the basic information for restoration

Site conditions and forest management affect dendrometric parameters of chestnut (Castanea sativa Mill.) coppices, but there is modest knowledge on the effect of stand dendrometric characters on physical and mechanical wood characteristics. The aim of this study was to verify these relationships in chestnut coppices that were 12–14 years old. Wood density, compression and bending strength, shrinkages were measured on shoots of five different stand in a vulcanic site in Monte Amiata (Central – Italy). Investigated stands differ in number of stools/ha and dominant height, diameter/basal area of the shoots. The main difference in the physical characters among the stands is density. The initial results of the study showed that physical, mechanical wood characters are more dependent by the shoot than by the site. There is a positive relationships between the number of stools/ha and density and a negative one among shoot dominant height and basal area with wood density. Spectroscopic profile by FTIR has not showed relevant differences among the stands. Wood anatomy has showed the breakpoint at cellular level.

Waterlogged archaeological wood is exposed to a high risk of biological degradation during the post-excavation phases of storage and restoration. For this reason, often biocides must be used to preserve wooden remains. In the present work three essential oils (cinnamon, wild thyme, and common thyme) were tested as possible alternative biocides to use in the preservation of waterlogged archaeological wood. The oils were first tested in vitro to establish the minimum inhibitory concentration (MIC) and to evaluate the biocidal activity on selected fungal strains. Then, the established MIC was applied on waterlogged archaeological wood samples and during an actual restoration treatment. The effectiveness of the oils was evaluated through cultural analyses, ATP quantification, and next-generation sequencing. The results showed that the oils caused a significant decrease in the vitality of fungal mycelia grown in vitro and of the microbiota present in treated wood and storage water. Furthermore, an influence on the composition of the bacterial communities of treated wood samples was observed. Although further tests are needed to evaluate interferences with the materials used during restoration procedures, essential oils could be considered as a possible alternative to the currently used biocide.

The great Beech forests extension in Europe has recently led to investigate the possible application of this hardwood species for the production of Cross-Laminated Timber (CLT) panels. In order to define the goodness of Beech CLT panels for structural applications, an extensive experimental study on novel, three-layered CLT panels made up with short procurement chain, Beech-Corsican Pine timber and melamine based adhesive was performed. The main aim is to define and summarize the mechanical performances of CLT panels both in the homogeneous and hybrid configurations. Major support is derived from bending and shear experimental investigations, both for the in-plane and perpendicular to-plan directions. Moreover, based also on Finite Element (FE) numerical simulations, the local and global mechanical performance of these novel panels is further assessed, towards a widely diffused market product (C24 Spruce CLT panels). The collected experimental and numerical results reveal an overall good behavior of homogeneous hardwood panels, and an excellent performance of hybrid softwood-hardwood configuration, with great opportunity on construction applications.

Waterlogged archaeological wood (WAW) is considered a precious material, first-hand account of past civilizations. Like any organic material, it is subjected to biodegradative action of microorganisms whose activity could be particularly fast and dangerous during the phases of excavation, storage and restoration. The present work aimed to characterize the microorganisms present in WAW during these tricky periods to evaluate the biological risk it is exposed to. The bacterial and fungal communities inhabiting woods coming from two archaeological sites (Pisa and Naples) were investigated through Next-Generation Sequencing (NGS). High-throughput sequencing of extracted DNA fragments was performed using the reversible terminator-based sequencing chemistry with the Illumina MiSeq platform. The analyses revealed that the two archaeological sites showed distinct richness and biodiversity, as expected. In all the WAWs, the bacterial community harbored mainly Proteobacteria, whereas Bacteroidetes was well represented only in Naples communities and taxa belonging to the phyla Chloroflexi only in the Pisa site. Concerning the fungal community, the two sites were dominated by different phyla: Ascomycota for Naples samples and Basidiomycota for Pisa. Interestingly, most of the identified bacterial and fungal taxa have cellulolytic or ligninolytic ability. These results provide new and useful background information concerning the composition of WAW microbiota and the threat it represents for this precious material.

Chestnut timber is a resource that has so far been underestimated. The production of laminated chestnut beams represents important progress; it is necessary to check its market performances and the opportunities offered from non-market characteristics. To ensure competitiveness margins in the future, dedicated chestnut timber policy is required. European Union policies for sustainable development converge towards the enhancement of forest resources. Hypothesis: enlargement of the range of wood products and increase in timber products usage can only be achieved if these products are more competitive than conventional. With respect to conifer timber, chestnut timber has competitive characteristics. However, chestnut timber has had very few opportunities for market development in the last decades. As result of its competitiveness margins, the laminated chestnut beams process has recently developed. For this product, a conventional market or competitiveness space has been established as well as its extension in relation to non-market characteristics. Market space has been defined by determining the producer’s reserve price limits, using the cost approach criteria; the consumer’s upper limit, using the market comparison approach; the expansion of the upper limit for the non-market characteristics, the environmentally friendly consumer price, determined through interviews with a sample of responsible consumers. Limits are: the producer’s reserve price is 752.68 €/m3; the consumer’s reserve price is 918.77 €/m3; in the main regional market (Rome district), the environmentally friendly consumer’s price is 1164.08 €/m3. Knowledge of the various market limits of chestnut timber allows producers to assess its competitive margins. Conservation over time of these margins, however, requires dedicated governance, as well as the adoption of a forest strategy aimed at promoting the timber production quality and a marketing plan to promote the knowledge of the characteristics of chestnut wood (market and non-market characteristics) and increase the number of responsible consumers.

Land degradation is perceived worldwide as a key process of resource depletion, representing a paradigmatic issue in national and supra-national political agendas for the 21st century in both advanced and emerging economies. Trying to delineate a ‘new lexicon of land degradation’, the present study contributes to a holistic thinking of driving forces in local communities and regional contexts through a refined analysis and discussion of (apparent and latent) factors of land degradation. Rethinking the importance of five notions (time, space, scale, systems, and response) having an intimate linkage with land degradation allows a refined understanding of socio-environmental dynamics and the most appropriate actions to combat (or mitigate) land resource depletion. The conclusions summarize the rationale proposed in this work, and provide a brief outlook on future research addressing land degradation, its drivers and consequences.

Sustainability and ecotoxicity issues call for innovations regarding eco-friendly adhesives in the production of biocomposite wood materials, and solutions involving nano-scale and bio-based compounds represent a valid and promising target. One possible approach is to increase the performance of adhesives such as polyvinyl acetate (PVAc) or melamine-urea-formaldehyde (MUF) by means of nanoparticles in order to obtain a material with better mechanical and environmental resistance. When applying cellulose-based nanoparticles or tannin, the concept of a circular economy is successfully implemented into the forest/wood value chain, and chances are created to develop new value chains using byproducts of forestry operations. In this study, assortments coming from young sweet chestnut (Castanea sativa Mill.) coppice stands were utilized for the preparation of single lap joint assemblies using different commercial adhesives (PVAc, MUF) and cellulose nanocrystals (CNC) and tannin as additives. The results showed that addition of CNC and tannin to PVAc glue increased tensile shear strength in lap joint tests presenting a promising base for future tests regarding the addition of CNC and tannin in MUF or PVAc adhesive formulations. Unfortunately, the tested bio-based additives did not reveal the same encouraging results when tested in the wet state.

Research Highlights: Chestnut trees’ (Castanea sativa Mill.) growth and their responses to climate are influenced by stand-characteristics and managements. This study highlighted that chestnut tree-ring growth is not particularly influenced by climate, while minimum temperature showed a positive relation with both intrinsic water-use efficiency (WUEi) and δ¹8O. Background and Objectives: The aim is to check the responses of chestnut trees to climate conditions and the role of stand structure and management. Materials and Methods: Stands with 12–14-year-old shoots were studied using dendrochronological and isotopic (δ18O and δ13C) approaches. Correlations with climate parameters were investigated and principal component analysis was performed using site-characteristics and tree growth parameters as variables. Results: Correlations between tree-ring width (TRW), tree-ring δ18O, and δ13C-derived intrinsic water-use efficiency (WUEi) revealed stand-dependent effects. The highest Correlations were found between climate and tree-rings’ isotopic composition. Chestnut was sensitive to high-minimum temperature in March and April, with a negative relationship with TRW and a positive relationship with WUEi. δ18O signals were not significantly different among stands. Stand thinning had a positive effect on WUEi after 1–2 years. Stand competition (indicated by shoots/stump and stumps/ha) positively influenced both WUEi and δ¹8O.

Tannins are an important industrial product, with chestnut being one of the most representative species for their production, due to the occurrence that the species possesses within its wood quite big amounts of hydrolysable tannins. For industry, it is quite important to know at the cellular level where tannins are located – in the cell lumen or cell wall – and the efficiency of a particular tannin extraction process. The objective of this study was to identify and locate tannins in chestnut wood by means of UMSP (UV microspectrophotometry), considering both shoots and standards in coppice stands. The analyses were also carried out in standards before and after tannin extraction according to the parameters and methodology of an industrial process. Tannins were localized mainly inside the cell lumen of parenchymatic cells and vessels, and they were visible in parts adjacent to the cell walls. In shoots, they have been found also in locations where the cell wall is degraded. In the standards, tannins with more UV absorbance were detected and evidently present in the corners of wood cells. After tannin extraction, the cell lumen was empty, but tannins, even with lower absorbance values, were still present, mainly in the cell corners. The results open up discussion on the utilization of residual wood flour as a by-product after initial tannin extraction, which could be further exploited from the overall perspective of a circular economy.

Plant roots play a key role in stabilizing slopes, particularly in the Mediterranean region, characterized by rough and unstable terrain. However, forest species differ in their stabilizing capacities. The purpose of this study is to fill the gap of knowledge on root biomechanical properties of relevant Mediterranean trees and shrubs in relation to slope stability. Root specimens of typical montane Mediterranean tree and shrub species were sampled in Southern Italy. Root characteristics, such as tensile strength (Tr) and root area ratio (RAR), were assessed from live roots sampled in trenches, while root cohesion was calculated. Power law functions yielded the best fit for the relationship of Tr versus root diameter; however, no significant relationship was found between root strength and root moisture content. RAR varied amongst different tree and shrub species. Roots of Quercus cerris L. were the most resistant to breaking under tension, while roots of Ilex aquifolium L. had the highest tensile strength among all shrub species. Results provide quantitative information on the role of root systems of montane Mediterranean forest species in stabilizing soils and will improve modeling of landslide susceptibility to the prevention and mitigation of natural hazards in mountain environments.

Lignin was isolated from wood wastes comprising Iroko sawdust (IR) and mixed sawdust from Iroko and Norway spruce (IRNS), furnished by a local wood houses producer. The respective acidolysis lignin fractions were structurally characterized using pyrolysis (Py)-GCMS, two-dimensional heteronuclear single quantum correlation nuclear magnetic resonance (2D HSQC NMR), Fourier-transform infrared FTIR and ultraviolet-visible (UV-VIS) spectroscopies, size exclusion chromatography, and standard wet-chemistry methods for Klason lignin and polysaccharides determination. The isolated lignin fractions were subsequently used for the preparation of lignin nanoparticles (LNPs) using a non-solvent method. LNPs were then used for wood surface treatment using a dip-coating technique. The coated wood samples were analyzed by colorimetry and scanning electron microscopy (SEM) before and after artificial weathering experiments in a UV chamber to investigate the UV protection potential of the LNPs coatings. Wood samples dip-coated with LNPs showed promising surface modifications resembling a sort of film of fused LNPs. Coatings made from IR-LNPs and IRNS-LNPs performed significantly better in artificial weathering experiments than uncoated reference samples.

The main objective of this research was to investigate climate-growth relationships and if climate is a possible cause of oak decline in a very representative peri-urban forest in the Mediterranean area. The dendrochronological behaviours of healthy trees and declining trees were compared according to compromised vitality as assessed by crown defoliation. The analysed parameters were ring and latewood widths. The results showed that ring widths and latewood depended directly on spring precipitation (April-May-June) and, inversely, on spring-summer temperature (April-May-June-July). The growth histories of healthy and declining deciduous oaks in Castelporziano, as evaluated by their crown vitality, were very similar. The onset of decline dates back to the middle of the 1940s, and a further irreversible growth depression was based on the increase in temperature in the 1980s. This climatic change is reflected roughly 13 years later in declining trees, 17 years later in the healthy ones, in a strong growth depression that appears very exacerbated by the recurrent warm extreme events after the 2000s. Latewood in our study did not add more to the total ring-width measurements, potentially because of a high state of tree suffering. Declining trees were in general older than healthy ones, but in this study, the difference in age was not different from a statistical point of view.
