枯木是脊椎动物和无脊椎动物的重要栖息地，是营养循环的关键因素和宝贵的碳库。枯木碳储量的差异取决于许多变量，如森林类型，小气候和森林management.AimsWe调查的枯木和森林管理之间的关系，在橡树林意大利南部。MethodsDeadwood C股票量化74林分下集约，粗放或多功能管理。考虑到腐朽类和类型的朽木（障碍，树桩和日志）的管理和C股票之间的关系进行了评估。ResultsIntensively管理的森林的特点是明显较低的平均水平的朽木C比其他形式的管理。多功能管理导致C的最高水平，主要是在日志和障碍，而广泛的管理导致高水平的C存储集中在snags.ConclusionResults的研究突出表明，森林管理措施极大地影响了森林中的死木的数量和质量的存在。
ContextDeadwood is an important habitat for vertebrate and invertebrate species, a key factor in the nutrient cycle and a valuable carbon pool. Difference in the deadwood C stock depends on many variables such as forest type, microclimate and forest management.AimsWe investigated the relationship between C stock in deadwood and forest management in oak stands of southern Italy.MethodsDeadwood C stock was quantified in 74 forest stands under intensive, extensive or multifunctional management. The relationship between management and C stock in deadwood was assessed taking into account the decay class and the type of deadwood (snags, stumps and logs).ResultsIntensively managed forests are characterized by significantly lower mean levels of deadwood C than the other forms of management. Multifunctional management resulted in the highest level of C, mainly in logs and snags, while extensive management resulted in high levels of C storage concentrated in snags.ConclusionResults of the research highlight that forest management practices greatly influence the quantitative and qualitative presence of deadwood in forests.
