Anthropogenic habitat fragmentation represents a major obstacle to species shifting their range in response to climate change1. Conservation measures to increase the (meta-)population capacity2 and permeability of landscapes3 may help but the effectiveness of such measures in a warming climate has rarely been evaluated. Here, we simulate range dynamics of 51 species from three taxonomic groups (vascular plants, butterflies and grasshoppers) in Central Europe as driven by twenty-first-century climate scenarios and analyse how three habitat-based conservation strategies (establishing corridors, improving the landscape matrix, and protected area management) modify species’ projected range size changes.(...)
