Edges and their effects on wildlife is an area of conservation interest. Despite considerable effort a synthetic understanding of when edges will have positive, neutral, or negative effects on species remains elusive. To develop a mechanistic understanding of why boreal forest songbirds do or do not react to edges requires a shift in approach whereby edges of different types are compared. Comparing edge types in different regions using the same methodological approaches is key to determining why edge behavior varies. Current literature suffers from a lack of quantitative standards for reporting edge effects making it difficult to evaluate why particular edges have an effect based on literature reviews or meta-analysis. Development of field and statistical techniques that convert data to common standards is critical to advancing our understanding of edge impacts.

边缘及其对野生动物的影响是一个具有保护意义的领域。尽管付出了相当大的努力，但对边缘何时对物种产生积极、中性或消极影响的综合理解仍然难以捉摸。要发展一个机械的理解，为什么北方森林鸣禽做或不做反应的边缘需要一个转变的方法，即不同类型的边缘进行比较。使用相同的方法比较不同地区的边缘类型是确定边缘行为为何不同的关键。当前的文献缺乏报告边缘效应的定量标准，因此很难根据文献综述或荟萃分析来评估特定边缘为何具有效应。开发将数据转换为通用标准的现场和统计技术对于促进我们对边缘影响的理解至关重要。
