Climate is often singled out as the primary range limiting factor at large scales, while other environmental factors, notably soil, are thought to predominate at smaller scales. However, the postglacial migrational lag hypothesis controversially suggests that many species are strongly dispersal‐limited and still expanding from their ice age refugia. We investigated the importance of postglacial migrational lag, climate, and soil as range determinants for 47 widespread forest plant species across nemoral Europe (47.0–60.0°N, west of 24.0°E) using regression modeling, information‐theoretic model selection, multi‐model inference, and variation partitioning. Migrational lag was represented by a measure of accessibility to recolonization from ice age refugia.

Twelve species were largely ubiquitous and not analyzed further. For the remaining species, there was strong support for climate, soil, and accessibility to postglacial …
