Recent changes in arctic vegetation might not be driven by climate change alone. Legacies of human activities have received little attention as a contributing factor. We examine the extent to which traditional human activities (hunting, herding, fire, wood extraction, and agriculture) have had lasting effects on arctic woody plant communities and therefore might continue to affect biome-wide responses to climate change. Evidence suggests that legacies are likely to be evident across meters to hundreds of kilometers and for decades, centuries, and millennia. The evidence, however, is currently sparse, and we highlight the potential to develop systematic assessments through a circumarctic collaboratory consisting of a network of interdisciplinary field sites, standardized protocols, participatory research, and new approaches. We suggest that human activities should be brought into consideration to increase our understanding of arctic vegetation dynamics in general and to assess woody plant responses to clim...

北极木本植物动力学中人类历史活动的遗产

北极植被最近的变化可能不仅仅由气候变化驱动。人类活动的遗产作为促成因素很少受到关注。我们研究了传统人类活动（狩猎、放牧、火灾、木材开采和农业）对北极木本植物群落产生持久影响的程度，因此可能会继续影响整个生物群落对气候变化的反应。有证据表明，遗产很可能在数米到数百公里的范围内以及数十年、数百年和数千年中明显存在。然而，目前证据很少，我们强调了通过由跨学科现场站点网络、标准化协议、参与式研究和新方法组成的环北极合作机构开发系统评估的潜力。
