Land-use legacy on forest dynamics at both stand and landscape scale can last for centuries, affecting forest structure and species composition. We aimed to disentangle the history of the charcoal production legacies that historically shaped Mont Avic Natural Park (Aosta Valley, Italy) forests by integrating LiDAR, GIS, anthracological, and field data at the landscape scale. We adopted different geostatistical tools to relate geographic layers from various data sources. The overexploitation due to intensive charcoal production to fuel mining activities shaped the current forests by homogenising their structure and species composition into dense and young stands with a reduction in late seral species such as Norway spruce (Picea abies) and an increase in pioneer species such as Mountain pine (Pinus uncinata). The multidisciplinary and multi-scale framework adopted in this study stresses the role of historical landscape ecology in evaluating ecosystem resilience to past anthropogenic disturbances.
土地利用对林分和景观尺度森林动态的影响可持续数百年，从而改变森林结构和物种组成。我们旨在通过整合景观尺度的 LiDAR、GIS、炭屑学和野外数据，厘清历史上曾塑造意大利奥斯塔山谷蒙泰阿维奇自然公园（Mont Avic Natural Park）森林的木炭生产历史。我们采用了不同的地统计学工具来关联来自不同数据源的地理图层。过去密集的木炭生产曾为采矿活动提供燃料，导致过度开采，使当前的森林结构和物种组成变得单一，林分密度较大且幼龄化，挪威云杉（Picea abies）等晚生种减少，山松（Pinus uncinata）等先锋种增加。本研究采用的多学科和多尺度框架强调了历史景观生态学在评估生态系统对过去人为干扰的恢复能力方面的作用。
