Global and national commitments to slow biodiversity loss by expanding protected area networks also provide opportunities to evaluate conservation priorities in the face of climate change. Using recently developed indicators of climatic macrorefugia, environmental diversity, and corridors, we conducted a systematic, climate‐informed prioritization of conservation values across North America. We explicitly considered complementarity of multiple conservation objectives, capturing key niche‐based temperature and moisture thresholds for 324 tree species and 268 songbird species. Conservation rankings were influenced most strongly by climate corridors and species‐specific refugia layers. Although areas of high conservation value under climate change were partially aligned with existing protected areas, ∼80% of areas within the top quintile of biome‐level conservation values lack formal protection. Results from this study and application of our approach elsewhere can help improve the long‐term value of conservation investments at multiple spatial scales.

建立面向气候的北美保护区网络：将气候变化避难所和走廊纳入保护规划

通过扩大保护区网络来减缓生物多样性丧失的全球和国家承诺，也为面对气候变化评估保护优先重点提供了机会。利用最近开发的气候宏观避难所，环境多样性和走廊指标，我们对整个北美地区的保护价值进行了系统的，以气候为依据的优先排序。我们明确考虑了多个保护目标的互补性，捕获了324种树种和268种鸣禽物种基于关键生态位的温度和湿度阈值。气候变化走廊和特定物种避难所层对保护等级的影响最大。尽管在气候变化下具有高度保护价值的地区与现有的保护区部分一致，在生物群落一级的保护价值最高的五分之一区域中，约有80％的区域缺乏正式保护。这项研究的结果以及我们在其他地方应用该方法的结果可以帮助提高在多个空间尺度上的保护投资的长期价值。
