Původ travinné vegetace slatin v Čechách: sukcese kontra cenogeneze

Current interpretations based on palynological data consider the vegetationof fen peats (calciphilous mires) young and human-made because of its developmentfrom deforested alder woodlands. However, this oppinion can be acceptedonly when succession of the majority of stands is considered. Regardingthe coenogenesis of plant communities (i.e. the historical developmentof vegetation units), this vegetation in the Czech Republic is a relicfrom the early Holocene. Palaeochoric (e. g. endemic) taxa which are crucialfor fen peat communities survived from this period through a system ofopen refugial patches. These small plots resistent to woodland invasionare documented by using examples from the recent landscape.
