外来入侵物种(IAS)是全球和当地生物多样性的主要威胁之一。在森林生态系统中,国际会计准则造成的威胁包括杂交,传播疾病和物种竞争。这篇综述旨在分析外来植物物种对森林更新的影响,我们认为这是未来森林生态系统生存的树木生态学的关键阶段之一。研究的重点与从业者直接相关,森林管理者和森林养护管理。有了这个系统的审查,我们旨在提供48项研究的概述,这些研究报告了IAS在欧洲温带森林中的影响和/或管理。我们遵循了一个多步骤的协议来汇编文献综述的出版物,有9个搜索查询,总共产生3,825个点击。经过几轮还原,我们最终总共发表了48篇论文。我们确定了53种维管植物对中欧森林的森林再生有负面影响。总的来说,在24项研究中,据报道有21种树种受到IAS的影响。综述综合的结果表明,五种影响机制会影响本地树种的再生成功:资源竞争,化学对再生的影响,对再生的物理影响,对再生的结构影响和通过与其他物种相互作用的间接影响。我们在综合管理措施中确定了建议在生物入侵的不同阶段应用的措施。通过审查科学文献,相关成本和管理措施所需的资源报告不足或无法获得。因此,我们可以得出结论,改善科学与实际森林管理之间的联系非常重要。我们希望这篇综述将为旨在保护欧洲温带森林生态系统生物多样性的入侵植物物种研究和管理提供指导。
Invasive alien species (IAS) are one of the major threats to global and local biodiversity. In forest ecosystems, the threats caused by IAS include hybridization, transmission of diseases and species competition. This
review sets out to analyze the impact of alien plant species on forest regeneration, which we consider to be one of the key stages in tree ecology for the survival of forest ecosystems in the future. The focus of the study is directly relevant to practitioners, forest managers and the conservation management of forests. With this systematic
review, we aim to provide an overview of 48 research studies reporting on the impact and/or management of IAS in European temperate forests. We followed a multi-step protocol for compiling the publications for the literature
review, with nine search queries producing a total of 3,825 hits. After several reduction rounds, we ended up with a grand total of 48 papers. We identified 53 vascular plant species having a negative influence on forest regeneration in Central European forests. In total, 21 tree species are reported to be impacted by IAS in 24 studies. The results of the
review synthesis show that five impact mechanisms affect the regeneration success of native tree species: competition for resources, chemical impact on regeneration, physical impact on regeneration, structural impact on regeneration and indirect impact through interaction with other species. We identified in our synthesis management measures that have been recommended for application at different stages of biological invasions. The associated costs and required resources of management measures are under-reported or not accessible by reviewing the scientific literature. We can thus conclude that it is very import to improve the links between science and practical forest management. We expect that this
review will provide direction for invasive plant species research and management aimed at protecting biodiversity in European temperate forest ecosystems.
