在过去的几十年里，树木入侵的重要性不断上升（更多的物种，更大的入侵面积，更多类型的影响，管理挑战的复杂性增加），并且越来越多地从多个角度进行研究。这项研究跨越了许多学科，包括生态学、种群生物学、遗传学、遥感、生态建模、风险分析、资源经济学，以及越来越多的人文学科。在理解模式和过程方面已经取得了实质性的进展，但仍有许多未解决的问题。只有少数入侵树木得到了很好的研究，其中许多只在其入侵范围的一小部分。入侵的树木通常会产生重大影响，特别是当它们入侵以前没有树木的植被时。树木有几个特征，使它们有助于理解生物入侵的关键方面（入侵性和不可侵入性的决定因素），而且还有助于理解将生物入侵视为环境问题的人类感知和价值观的全部范围。这篇社论提供了背景资料，并总结了2012年9月在阿根廷举行的一次研讨会的主要成果，该研讨会旨在总结当前关于关键主题的知识，并确定研究人员和管理人员面临的最重要挑战。《生物入侵》特刊中的16篇论文跨越学科、地理区域和分类群，提供了关于入侵途径和历史观点、检测和监测、入侵决定因素、功能和影响以及管理者面临的许多挑战的新见解。
Tree invasions have escalated in importance in the last few decades (more species, greater area invaded, more types of impacts, increasing complexity of management challenges), and are increasingly studied from many perspectives. This research spans many disciplines, including ecology, population biology, genetics, remote sensing, ecological modelling, risk analysis, resource economics and, increasingly, the humanities. There has been substantial progress in understanding patterns and processes, but many unanswered questions remain. Only a few invasive trees have been well studied, many of them in only a small part of their invasive range. Invasive trees often have substantial impacts, especially when they invade formerly treeless vegetation. Trees have several features that make them useful for understanding key aspects of biological invasions (the determinants of invasiveness and invasibility), but also the full spectrum of human perceptions and values that frames biological invasions as an environmental problem. This editorial provides background and summarizes the main outputs from a workshop held in Argentina in September 2012 that set out to summarize current knowledge on key topics and to determine the most important challenges facing researchers and managers. The sixteen papers in the special issue ofBiological Invasionsspan disciplines, geographic regions and taxa and provide novel insights on pathways and historical perspectives, detection and monitoring, determinants of invasiveness, function and impact, and the many challenges that face managers.
