How can we effectively restore species richness and natural composition of a Molinia-invaded fen?

摘要: We applied three different types of restoration measures (once- and twice-a-year mowing, litter removal) in a block experiment over 6 years to test the effects on species density and composition vascular plants and bryophytes. Species density and composition both taxonomic groups were significantly influenced by but not pure removal. Contrary to bryophytes, plant was more strongly influenced mowing than annual mowing. recommend instead traditional late annual as an initial measure. Since the effect standing Molinia crop our long-abandoned fen turned out be more detrimental other than accumulated litter, we do any management that is based removal rather mowing.
