Location: between Marienberg and Reitzenhain at an elevation of 660 to 740m above sea level
Also referred to as Röschhaide, this moor area is located along the Erdmannsbach in a restricted military zone of the Marienberg mountain infantry batallion. It is characterized mainly by spruce forests and spruce moor woodlands. Peat layers just three meters in depth are present, with peat beds having been severely corroded or composted. They are mainly comprised of sedge peat and wood peat. The area was drained in the 19th century for forestry. Drainage ditches are cut deep in the mineral ground and were also cleared in the 20th century. Damage done to the moor by drainage and the drying out associated with this are very grave.
A hydrological survey was performed in preparation for re-watering work. The survey focused on mapping out the area, including its drainage ditches and geomorphological characteristics. Over 100 additional holes were drilled in order to determine the depth of the peat layer and identify peat characteristics. Peat samples collected through drilling were analyzed in the lab for pH values and nutrient content. Vegetation present in the area was further identified. Based on the action plan developed, 40 dams were installed in the moor from 2005 to 2007. The fact that the area is located on a military training ground complicated performance of the work, since the grounds were only accessible at times when there would be no shooting. An official event to celebrate completion was held as soon as 2007.
