イタリア南部のPinus radiata林で大規模山火事後に焼損した丸太を侵食防止バリアとして再利用し、24ヶ月間の構造耐久性と生態的効果を評価。中程度の焼損樹皮の丸太が最も安定し、時間経過・樹皮損傷・音響波速度が劣化の主な予測因子。等高線配置の丸太は流出と侵食を低減し、実生定着を促進。焼損丸太の選定指針を提供。
English
This study evaluates the structural durability and ecological effectiveness of burnt logs used as erosion barriers after a large wildfire in a Pinus radiata stand in Southern Italy. Over 24 months, moderately burnt bark logs retained the highest mechanical stability, with time since fire, bark damage, and acoustic wave velocity as key decay predictors. Contour-aligned logs reduced runoff and erosion while promoting better seedling establishment. The findings offer practical guidance for selecting fire-affected logs in nature-based solutions for post-fire Mediterranean forest restoration.

📄 Abstract（原文）
Abstract Mediterranean forest ecosystems are increasingly threatened by wildfires, compromising slope stability and delaying natural regeneration. In these contexts, Nature-based Solutions (NbS) represent sustainable approaches for post-fire restoration. This study evaluated the short- to medium-term structural durability and ecological effectiveness of fire-affected logs repositioned as erosion barriers after a large wildfire in a Pinus radiata stand in Southern Italy. The objectives were to assess the mechanical degradation of burnt logs using non-destructive technologies, to develop a predictive decay model, and to evaluate the effects of log arrangement on hydrological response and natural forest regeneration. Burnt logs were monitored over 24 months and classified according to bark damage. Wood decay was modelled using beta regression based on physical and mechanical parameters. Moderately burnt bark logs retained higher mechanical stability than logs with intact or completely burnt bark. Time since fire, bark damage class, and acoustic wave velocity were the main predictors of decay. Contour-aligned logs reduced runoff and erosion while promoting a higher proportion of established seedlings, whereas randomly distributed logs showed greater initial regeneration density but lower regeneration quality. These findings provide practical guidance for selecting fire-affected logs in NbS and improve understanding of their structural and ecological role in post-fire Mediterranean forest restoration.
