生境阈值通常被解释为最低要求的生境面积，随后被提升为自然资源政策和规划中的保护目标。不幸的是，最近的几次审查和警告信息的应用栖息地阈值保护在很大程度上被置若罔闻，导致一个危险的过度简化和概括的概念。我们强调了过度简化/过度概括的政策文件中的栖息地阈值研究的结果，这种过度概括的后果，并为栖息地阈值研究，保护应用程序的方向，而不会冒过度概括的风险。我们认为，为了避免误用的栖息地阈值保护，我们不应该把重点放在广义的名义栖息地价值（即栖息地的数量或百分比），但对使用的栖息地阈值模型进行比较练习的面积敏感性或识别环境危险。此外，我们应该继续专注于了解物种对栖息地变化的反应的过程和机制。最后，只有当阈值是详细的，物种特异性的，并仅转化为研究区域特定的保护目标时，才能专注于推导标称值阈值量的研究才能这样做。由Elsevier BV发布这是CC BY-NC-ND许可证下的开放获取文章（http：//creativecommons. org/licenses/by-nc-nd/4.0/）。
Habitat thresholds are often interpreted as the minimum required area of habitat, and subsequently promoted as conservation targets in natural resource policies and planning. Unfortunately, several recent reviews and messages of caution on the application of habitat thresholds in conservation have largely fallen on deaf ears, leading to a dangerous oversimplification and generalization of the concept. We highlight the prevalence of oversimplification/over-generalization of results from habitat threshold studies in policy documentation, the consequences of such over-generalization, and directions for habitat threshold studies that have conservation applications without risking overgeneralization. We argue that in order to steer away from misapplication of habitat thresholds in conservation, we should not focus on generalized nominal habitat values (ie, amounts or percentages of habitat), but on the use of habitat threshold modeling for comparative exercises of area-sensitivity or the identification of environmental dangers. In addition, we should remain focused on understanding the processes and mechanisms underlying species responses to habitat change. Finally, studies could that focus on deriving nominal value threshold amounts should do so only if the thresholds are detailed, species-specific, and translated to conservation targets particular to the study area only.© 2015 The Authors.
