These vegetation types used to occur in turf ponds in the low lying peatland area, created by peat dredging and filled with water due to seepage of mesotrophic, well-buffered groundwater. One of the goals of the National Nature Policy Plan is to create new opportunities...
Acidification and eutrophication have caused great changes in fen ecosystems in The Netherlands. The main problems are the surplus of acid rainwater, forming a lens above the calcareous groundwater, and the blanket effect of the Sphagnum cover which results in a loss of rare species and species-rich plant communities. Research on effects of restoration measures was carried out in a floating fen...
