Four decades of vegetation development in a percolation mire complex following intensive drainage and abandonment

摘要: Background: Many minerotrophic fens in Central Europe have undergone similar sequences of land-use transformation. Drained and used as meadows or pastures for decades the twentieth century, they were abandoned 1990s due to changes agricultural economics. This sequence change has a severe impact on vegetation is likely initiate secondary succession possibly leading an impoverishment species diversity taxonomic homogenisation.Aims: We assess use subsequent abandonment composition percolation fen north Germany characterise successional abiotic site conditions.Methods: In 2010, we resampled 77 plots phytosociological survey from 1967–1970 lowland mire complex lower Recknitz valley, north-east Germany. These included three characteristic types fens. To investigate quantify dissimilarity measures,...
