Land-use history affects vascular plant composition of calcareous grasslands – Does it affect cryptogam composition, too?

Land-use history and habitat age are considered highly important regarding the species composition and conservation value of, e.g., grasslands and forests. Ancient sites, i.e., sites with a continuous habitat history, are thought to be richer in rare, threatened, and more specialised species than re...
