Brögberner Teiche - Baccumer Bruch

Brögberner Teiche - Baccumer Bruch is a landscape in the east of the city of Lingen (Ems) . It extends from the east of the village of Brögbern to the north of the village of Baccum .

The 1000  hectare landscape was part of the “Fascination Soil” project, which was initiated by the districts of Osnabrück , Grafschaft Bentheim , Emsland , Vechta and the city of Osnabrück (OBE region), the external location of the Expo 2000 in Hanover . In the development and testing project (E + E project) "Ecologically oriented dismantling of the Schillingmanngraben / Brögberner Teiche" funded by the Federal Agency for Nature Conservation , the State of Lower Saxony and the District of Emsland, it was examined which ecological improvements can be achieved, if so 10 percent of the landscape is used, maintained and developed from a nature conservation perspective.

The city of Lingen (Ems) was responsible for the project, which cost around DM 15 million and was scientifically supervised by the Federal Agency for Nature Conservation. The project was accompanied by working groups from the Carl von Ossietzky University of Oldenburg .

Around 210,000 m² of earth were moved for the redesign. 175,000 m² could be used again in the individual measures.

During the expo there was a multimedia and interactive exhibition in an old wage house in the project area. The exhibition was conceived with the question of how multimedia technologies can be used in the field of environmental protection. The exhibition and the project area were visited by more than 50,000 people.

background

The area, which lies in the natural area Lingener Land - Brögberner valley sand area, is drained by several brooks and ditches . Remains of former moors can be found in the lowlands and on the edge of the terminal moraines bordering the Baccumer Mountains to the south . Until the middle of the 20th century, the area was characterized by a varied landscape. Fields and grassland areas of different humidity levels alternated with unused fens and fen wood surfaces from. The agricultural land was divided into small areas by a comprehensive system of hedges . In the 1950s and 1960s, large areas of the territory were drainage measures under cultivation made and converted into arable land, which, as well as the remaining grassland areas were farmed intensively. Only a small proportion of the area of ​​around seven percent was still close to nature, including degenerate residual areas of fen meadows, damp and wet alder forest and moderately damp pedunculate oak and birch forest and hedges.

The project area encompasses the large and small Brögberner pond, parts of the Lingener Mühlenbach, the Schillingmanngraben and the Kaienfehngraben, a fen meadow , hedge systems, the Baccumer Bruch and wet meadows on an area of ​​110 hectares . Intensive agriculture continues to be practiced on the remaining areas.

Between 1989 and 1999, moist to wet biotopes were restored and networked with one another through a variety of measures.

Brögberner ponds

The Brögberner Ponds are a pond landscape in the northeast of Lingen (Ems), east of the village of Brögbern.

The pond landscape is shaped by the 27.2 hectare wetland Großer Brögberner Teich in the north, which was restored by spring 1995, and the 11.8 hectare wetland Kleiner Brögberner Teich in the south, which was restored by winter 1997/1998.

In the area of ​​the Brögberner ponds, formerly agriculturally used areas were converted into wetlands by rewetting . The wetland area Großer Brögberner Teich includes water areas, siltation and swamp zones as well as wet forest areas. At normal water levels, around half of the water from the Lingener Mühlenbach that runs here is channeled through the ponds. In order to investigate the extent to which the nutrients nitrogen and phosphate dissolved in the water can be removed naturally, the ponds are designed as nitrification and denitrification sections. For this purpose, an island landscape planted with willows and alders was created, in which the water is first enriched with oxygen and nitrogen compounds are oxidized to nitrate by microorganisms (nitrification path). In the last third of the ponds, the water is passed through a sand back, in the absence of air the nitrate to elemental nitrogen is reduced is (Denitrifikationsstrecke). This is then released into the air or removed from the water by reeds and rushes .

The small Brögberner Teich wetland, which is traversed by the Schillingmanngraben, also includes bodies of water, silting up and marsh zones, and wet bushes. It was transformed into an alder and willow break zone with a relatively long retention time for the water and thus serves to break down adsorbable organically bound halogen compounds (AOX) by microorganisms. The adsorbable organic halogen compounds are mainly residues of pesticides , which are generally difficult to break down .

The areas created can also absorb water from the Lingener Mühlenbach or the Schilligmannsgraben in the event of a flood and thus serve as a retention area .

Streams

In addition to the design of the pond landscapes, the watercourses of the Lingener Mühlenbach, the Schillingmanngraben and the Kaienfehngraben have been remodeled in a natural way over a length of around six kilometers. At the Lingener Mühlenbach the river meadow landscape was restored on 4.7 hectares by spring 1996 and on the Schillingmanngraben by the winter of 1997/98 on 7.2 hectares . On all three bodies of water, for the most part, 15 to 20 meter wide strips of water were created on both sides and the embankments were flattened, widened and planted in sections. The water can find its way through different areas with flat and steep banks, rinsing lines , meanders and still water zones. The wide waterfront strips also mean that nutrients and pollutants from the adjacent agricultural areas are reduced into the streams.

Baccumer fraction

In the area of ​​the Baccumer Bruch a 37.4 hectare wetland was created. The area, which was heavily drained, has been used extensively since 1992. After the trenches had been dismantled and a shallow fen lake had been built, rewetting began in the spring of 1996. The Baccumer Bruch was again a larger wetland with alder forest, fen meadows and water areas with silting and swamp areas.

Wet meadows

In the area of ​​a moor meadow near Brockhausen, the use was extensive and the area was watered over an area of ​​six hectares and small bodies of water were created by 1992.

Hedges

The historically evolved system of hedges, which divided the area into small areas, was largely eliminated by the end of the 1980s. As part of the project, up to the winter of 1997/98, around nine hectares of hedges, Benjes hedges , hedgerows and stone walls typical of the region, were re-established over a length of around eight to nine kilometers and the existing hedge system was networked and expanded again. All hedges were provided with a wide weed border , which significantly optimizes the ecological function of the hedges.

Recreation

The development area is accessible via several routes for cyclists, inline skaters and pedestrians. There are several information boards along three excellent routes. An adventure trail runs in the area of ​​the Great Brögberner Pond . This originally consisted of untreated wood, which, however, rotted over time, so that the path had to be renewed. In addition, three observation towers have been built on the Great and Small Brögberner Pond . Another is at the Baccumer Bruch.
