Kladener Plage nature reserve and Mildenitz breakthrough valley​

Mecklenburg-Western Pomerania

Plague of Kladen

Mildenitz

The Klädener Plage and Mildenitz-Durchbruchstal nature reserve is a 114-hectare nature reserve in Mecklenburg-Western Pomerania, five kilometers northwest of Dobbertin . It was expelled on March 13, 1996. The nature reserve serves to preserve the communities of a silted lake - the Klädener Plage - as well as a near-natural part of the Mildenitz with its breakthrough valley through the terminal moraine to the Black Lake.

The eponymous place Kläden is not far to the northeast. The state of the area is assessed as good. The Mildenitz shows natural dynamics again after the water maintenance and the remaining dead wood in the course of the stream. In the Klädener Plage, a permanently high water level could be achieved by giving up trench maintenance. However, the litter meadows there are currently not used. The protected area is located in the Nossentiner / Schwinzer Heide nature park and is part of an FFH and bird protection area under EU law .

A signposted educational trail leads through the area.

history

The Kladener Plage was first mentioned in 1237 as Lake Wostrowitz . Nicolaus , Herr zu Rostock documented the boundaries of the Dobbertiner monastery area, including Lake Wostrowitz (the drained waters of the Klädener and Dobbiner See), today's Klädener Plage and the Dobbiner Plage.

The Mildenitz had a strong influence on the development of the area's landscape. It is located in the central part of the protected area. The Mildenitz breakthrough valley between the Alte Mühle and the Black Lake is, along with the breakthrough valleys of the Warnow and Nebel rivers, one of the major Mecklenburg breakthrough valleys within the ice edge of the Pomeranian stage of the Vistula glacial period . In the area of ​​the Early Pomeranian Advance, the Mildenitz cut into a gravelly plateau of the terminal moraine about 20 meters deep over a stretch of two kilometers, forming a breakthrough valley. Impact and sliding slopes are pronounced. Both Talränder proceed at 60-64 m  HN and each adjoin a largely flat, gently sloping to the north plateau, which is closed forested with pines and beeches. Within the resulting Kerbsohlental a structure of the valley slopes by several terraces and a peripheral breakdown by dry valleys is evident. In the Mildenitz breakthrough valley, seven levels of leveling are formed at different altitudes, five of which are regarded as terraced formations of the Mildenitz and are named after their average height above the river.

The old mill was operated as a water mill until the 19th century.

To the northwest of the village of Dobbertin, there is a sand area , in which the Klädener Plage is also located as a flat, undulating lowland area with sandy knolls. In the Wiebeking map of 1786, the Klädener See (formerly 42 m above sea level) is recorded in its original form. The Kladener See still existed as a shallow body of water until around 1798. The lake goes back to a form of dead ice , which over the course of time has been filled with sea ​​chalk muds up to six meters thick .

The beginning of the lowering of the water level and the draining of the swampy Klädener Wiesental was marked by several setbacks. From 1809 to 1816 the drainage work was stopped due to lack of funds. Since the Kladener See was not yet completely dry, further trenches had to be dug to drain the spring water. With the straightening of the Mildenitz from 1860 to 1862, there was better grassland extraction and haymaking .

The old bridge at the Klädener mill was replaced by a massive one in 1862. The plan for the excavations to straighten the river was already drawn up in 1849-1851 by the Parchim hydraulic engineer Garthe and then carried out by the contractor Kleinert from Güstrow.

The Kladener Plage is one of the bogs fed by mineral soil water and is a fen area. Until 1945 large parts of the Klädener Plage were used for agriculture as young cattle paddocks and hay meadows. Since the ditch maintenance in the plague was made more difficult by the extensive pool clays and lime-silicate muds , there was rewetting with reed growth in these areas during the war years. After 1945 the edge areas were only grazed sporadically. From 1949 the forestry workers' fields were reforested with pine and spruce and in the 1950s the paddocks were planted with poplars and alders. At the end of the sixties, black pines were reforested on the main drainage ditch leading to the Mildenitz. From 1954 to 1967 there was also a mining of sea chalk as fertilizer. Only the Mildenitz breakthrough valley has been forest for a historically longer period of time.

Flora and fauna

Pedunculate oak designated as a natural monument near the old mill

A large part of the Klädener Plage is occupied by reed beds. Formative species are marsh marigold , marsh sitter , adder tongue and panicle sedge . To the north there are meadows with cabbage thistle.

In the area of ​​the steep slopes of the Mildenitz, Buchenwald clogs with wire forks. The beeches are in places over 200 years old. In the area 86 birds were detected, including wagtail , Kingfisher , bittern , Corncrakes , Tüpfelralle and dippers . Numerous bats find a habitat in the old beech trees that accompany the stream. The fringed bat , the great bearded bat and the great noctule bat were identified as species . The very rare small river mussel lives in this area of ​​the Mildenitz, while it no longer occurs in the further course up to the confluence with the Warnow. In addition to the narrow and bellied diaper snail, the otter has also been sighted. Furthermore, 251 species of fungus were mapped.

Several Douglas firs (Pseudotsuga menziesii) over 40 meters high are designated as natural monuments within and on the edge of the nature reserve in Section 4113a of the Kläden forest district. An almost 700-year-old pedunculate oak (Quercus robur) with a trunk circumference of 7.3 meters stands on Kädener Berg east of the village near the federal highway 192 . And on the hiking trail from Kläden to Alten Mühle, north of the Mildenitz, there are other English oaks marked as natural monuments.
