The Dubringer Moor ( Upper Sorbian Dubrjenske bahno ) is a nature reserve (NSG) in the district of Bautzen in northern Saxony. It is located in the three municipalities of Bernsdorf , Hoyerswerda and Wittichenau and covers an area of ​​around 1711 hectares . This makes it one of the largest nature reserves in Saxony .

In addition to forest and grassland areas , the nature reserve also includes several still waters (mainly ponds ) and moor areas . The Moor sink of Dubringer Moors is made up of intermediate and fens (including open regenerated moorland ) together and belongs to the type of flow Moors . The area is considered to be the largest still preserved bog complex in Upper Lusatia .

The nature reserve, which was designated for the first time in 1995, has the official identification D78. Because of its ecological importance and later designations, it is now part of the Natura 2000 network of protected areas of the European Union. Since 2011, the only slightly smaller FFH area Dubringer Moor (EU identification DE-4550-301) has existed almost congruently with the NSG . In addition, the NSG, supplemented by some open land areas adjacent to the east, was designated as a European bird sanctuary (EVG or SPA) Dubringer Moor (EU identifier DE-4550-451).

geography

location

The NSG Dubringer Moor is located between the cities of Hoyerswerda and Wittichenau .

It is limited roughly:

  • in the south through the villages of Wittichenau and its district Dubring and through the S95 road between Wittichenau and Kamenz and through the Schowtschickweg
  • in the north by the federal road B97 between Hoyerswerda, district Bröthen / Michalken , and Bernsdorf
  • in the west by a ridge running between the two named roads near the judicial mountain
  • in the east through the old, non-canalised river course of the Black Elster .

The area and the fish ponds it contains have belonged to the property of the Sankt Marienstern monastery in Panschwitz-Kuckau, founded in 1248, from the very beginning . The closed forest area in the western part of the NSG is also called St. Mariensterner Klosterforst . In the southern part of the moor is the Sunken Castle , a refuge for the Billendorfer culture .

Emergence

The formation of the Dubringer Moor can be traced back to the Elster Ice Age. Three terminal moraine walls were formed, which enclose the area of ​​the moor like a horseshoe open to the north. The water accumulated within this horseshoe area and peat could form from dead plant remains . Fresh peat forms a layer of about one millimeter per year. Since the peat layer of the Dubringer Moor is six meters thick, an age of 10,000 years can be assumed.

Hydrography

The desert pond in Dubringer Moor

Starting from the western border of the area at about 130 to 134 meters above sea ​​level and the height of the southern border at 127 meters above sea level, the water flowing off the terminal moraine walls results in a natural gradient towards the east, towards the limiting river course of the Black Elster about 120 meters above sea level. The main drainer of the Mooer is the Vincenzgraben .

The Schwarze Elster itself flows in its original river bed through the northeastern tip of the Dubringer Moor, southwest of the Hoyerswerda district of Dörgenhausen, and supplies some of the ponds for the local fish industry. Immediately west of the Dubringer Moor runs a regional watershed ( Zeißholz plateau ).

The annual mean temperature is given as 8.6 ° C and the mean annual rainfall with 635 mm. Both are determined by a frequent change between maritime and continental influences.

Development

Industry

The peat layer was mined in different places at different times, including industrially and especially after World War II, when the surrounding briquette factories were dismantled as reparations but fuel was required. Plans to dredge the raw lignite lying under the moor from 2010 onwards were dropped after the reunification of Germany. Technical certificates of the hydrogeological investigations are still available.

The boundaries of the nature reserve itself were once decided by the council of the Cottbus district and were extended by various laws. However, since a bog can only live if its water catchment areas are also preserved, there is a close correlation with the planning of the surrounding opencast mines, which change the groundwater levels significantly and sustainably.

tourism

The frog cycle path and the Krabat circular path lead through the Dubringer Moor . The traffic with motor vehicles is prohibited or is reserved for the local pond management. You can punt on the middle pond.

The Wittichenau local group of the Nature Conservation Union (NABU) regularly organizes hikes during the summer holidays. The observation tower between the Teichhaus Neudorf and the Hoyerswerda district of Michalken, inaugurated on July 2, 2009 by the Saxon Prime Minister Stanislaw Tillich , is used for this.

Importance for nature conservation

Wildlife

The Dubringer Moor is home to important breeding areas for threatened bird species that are on the Saxony Red List (Category 1 and 2).

The gray herons from the heron colony near the Knappenrode energy factory find their food here, but do not breed in the moor.

Some ponds that are no longer used for fish farming form the habitat for newts (mountain, pond and crested newts). The Dubringer Moor is also home to the otter , the American raccoon and the mink . As is usual in a heather landscape, there are also lizards , adders and blindworms . The fish ponds are used for carp breeding .

The wolf has resettled in the Dubringer Moor .

Flora

A large part of the free area of ​​the moor is occupied by cotton grass meadows. The Naturschutzbund also pays particular attention to the preservation of orchid meadows. With the support of the nature conservation authority, maintenance contracts were concluded with local farmers.
