Podcast; Previous studies on facilitating range shifts have stressed the need to increase landscape-scale connectivity to remove constraints on colonization, and our data substantiate this advice. However, we show that enhancing population survival can also help to facilitate range expansions, because populations at leading range edges face high extinction risk. Population survival can be improved directly through local management actions, such as enlarging patch size and increasing habitat quality, or indirectly by improving connectivity. Thus, local management can secure vulnerable populations at the range edge and provide larger and more stable migrant sources for future expansion and deserves consideration when facilitating range shifts under climate change.
