abstract = {Abstract: The Uckermark rural district has one of the highest concentrations of mires in all rural districts in Brandenburg. A large number of mire protection projects have been implemented here since 1990. These projects included the successful rewetting even of some strongly sloping mires, such as the Beesenberg spring fen. It is one of the largest and thickest spring mires in northeastern Germany. Despite of drainage since the end of the 18th century, particularly in the 1950s and 1960s, some typical spring fen areas have still been preserved up to the present day. Restoration supported by the Brandenburg Nature Conservation Fund were implemented in winter 2012/13 with the long-term goal to establish a growing spring fen again in parts of the Beesenberg mire complex. This paper describes the natural conditions for the mire restoration and the progress of construction activities. These included the complete deactivation of the ditches in the centre of the spring fen. Moreover, drainage structures were largely destroyed. By regeneration of the spring fen regime over large areas a significant rise in water levels resulted, as proven by water level records and photo documentation. Removal of the humified topsoil led to the clearance of some large areas and created new, moderately nutrient-rich, calcareous localities which quickly led to the re-establishment of plants of calcareous-rich fen habitats. The measures were accompanied by replanting species taken from appropriate locations. An already existing patch of the EU Habitat Directive species marsh angelica (Angelica palustris) was safely protected by the ecological construction management. Conclusions are drawn from the progress of the construction work useful for future mire restoration work at similar locations.},
