The origin of grasland vegetation of fen peats in the Czech Republic: succession versus coenogenesis

Current interpretations based on palynological data consider the vegetation of fen peats (calciphilous mires) young and human-made because of its development from deforested alder woodlands. However, this oppinion can be accepted only when succession of majority of stands is considered. Regarding th...

Summary:Current interpretations based on palynological data consider the vegetation of fen peats (calciphilous mires) young and human-made because of its development from deforested alder woodlands. However, this oppinion can be accepted only when succession of majority of stands is considered. Regarding the coenogenesis of plant communiries (i.e. historical development of vegetation units), this vegetation in the Czech Republic is a relic from the early Holocene. Paleochoric (e.g. endemic) taxa, which are crucial for fen peat communities survived from this period through a system of open refugial patches. These small plots resistant to woodland invasion are documented by using examples from the recent landscape.
