Socioeconomic changes, climate change, rural migration and fire exclusion have led to a high woody biomass accumulation increasing potential wildfire severity. Mechanical thinning and prescribed burning practices are commonly used to prevent large fires. The purpose of this study was to assess burning treatment effectiveness following mechanical thinning from biomass harvesting. Prescribed burning to reduce residue removal could help mitigate fire behavior, mainly in strategic management or critical focal points.Field samplings were conducted before and immediately after burnings on different environmental scenarios where fuel load was classified by categories. Prescribed fires reduced available fuel in all fuel categories, mainly in surface litter layer. Total fuel load reduction ranged from 59.07% to 86.18%. In this sense, fuel reduction effects were more pronounced when burns were conducted fewer than 10% on surface litter moisture. The difference in fuel consumption among scenarios was higher for most all woody fuel components and decomposition litter layer than for surface litter layer. Managers can use this information to design technical prescription to achieve the targets while decomposed litter retention maintaining the soil properties and biodiversity. Understanding the most effective “burn window” should help better plan prescribed burning, both in term of fire behavior and fuel consumption, without altering ecosystem properties.

规定的针对生物质开发中作物残留物清除的防火经验。在地中海盆地海洋松林中的应用

社会经济变化，气候变化，农村迁徙和火灾被排除在外，导致大量木质生物量积累，增加了潜在的野火严重性。机械减薄和规定的燃烧习惯通常用于防止大火。这项研究的目的是评估生物量收集后机械减薄后的燃烧处理效果。规定的燃烧以减少残留物的清除可能有助于减轻火灾的发生，主要是在战略管理或关键联络点上。现场燃烧是在燃烧之前和之后的不同环境场景中进行的，其中按负载对燃料类别进行了分类。规定的大火减少了所有燃料类别中的可用燃料，主要是地面垃圾层中的可用燃料。总燃料负荷降低范围为59.07％至86.18％。在这个意义上，当燃烧的表面垫料水分少于10％时，燃油减少的效果会更加明显。在大多数情况下，大多数木质燃料成分和分解垫料层的燃料消耗差异要大于表面垫料层的燃料消耗差异。管理者可以使用这些信息来设计技术方案，以实现目标，同时分解垃圾，保持土壤特性和生物多样性。理解最有效的“燃烧窗口”应有助于在防火行为和燃料消耗方面更好地计划规定的燃烧，而不会改变生态系统特性。在大多数情况下，大多数木质燃料成分和分解垫料层的燃料消耗差异要大于表面垫料层的燃料消耗差异。管理者可以使用这些信息来设计技术方案，以实现目标，同时分解垃圾，保持土壤特性和生物多样性。理解最有效的“燃烧窗口”应有助于在防火行为和燃料消耗方面更好地计划规定的燃烧，而不会改变生态系统特性。在大多数情况下，大多数木质燃料成分和分解垫料层的燃料消耗差异要大于表面垫料层的燃料消耗差异。管理者可以使用这些信息来设计技术方案，以实现目标，同时分解垃圾，保持土壤特性和生物多样性。理解最有效的“燃烧窗口”应有助于在防火行为和燃料消耗方面更好地计划规定的燃烧，而不会改变生态系统特性。
