干扰避难所-经历不太严重或频繁的干扰比周围的景观-提供了一个框架，以突出不仅在何处以及为什么这些生物遗产坚持作为邻近地区的变化，而且这些遗产在维持生物多样性的价值。最近对森林生态系统中干扰避难所的研究主要集中在火上，人们越来越认识到它在土地管理中的重要应用。鉴于森林的干扰过程范围广泛，科学家和土地管理人员必须更广泛地了解干扰避难所，特别是在人为气候变化的背景下。我们说明了干扰避难所的框架，通过个人和三个突出的森林干扰剂的相互作用：火灾，干旱和昆虫的爆发。我们提供的例子，干扰避难所和相关的应用，自然资源管理在北美西部，展示方法表征避难所，确定研究重点，并讨论为什么一个更全面的定义干扰避难所是相关的保护全球。
Disturbance refugia - locations that experience less severe or frequent disturbances than the surrounding landscape - provide a framework to highlight not only where and why these biological legacies persist as adjacent areas change but also the value of those legacies in sustaining biodiversity. Recent studies of disturbance refugia in forest ecosystems have focused primarily on fire, with a growing recognition of important applications to land management. Given the wide range of disturbance processes in forests, developing a broader understanding of disturbance refugia is important for scientists and land managers, particularly in the context of anthropogenic climate change. We illustrate the framework of disturbance refugia through the individual and interactive effects of three prominent forest disturbance agents: fire, drought, and insect outbreaks. We provide examples of disturbance refugia and related applications to natural resource management in western North America, demonstrate methods for characterizing refugia, identify research priorities, and discuss why a more comprehensive definition of disturbance refugia is relevant to conservation globally.
