  1. Rewet peatland (raise water table)

    A before-and-after study in 2001–2004 in a degraded fen in Hungary (Timmermann et al. 2006) reported changes in cover of plant community types following rewetting. For example, in the driest areas (winter water level <30 cm) Carex sedge communities dominated 2% of quadrats before rewetting but 31% three years after. Phalaris grass communities dominated 60% of quadrats before rewetting but 2% three years after. In wetter areas (winter water level >30 cm), cover of aquatic vegetation was 0–8% before rewetting and 23–52% after, but for sedge communities was 31–50% before rewetting and 0–9% after. These results were not tested for statistical significance. In 2001, a drained fen was rewetted (water table raised to 0–116 cm above the peat surface) by building dykes to divert river water into it. Before rewetting in August 2001 and annually until 2004, the dominant plant community type was recorded in fourteen 25 m2 quadrats along each of fourteen 100 m transects.
