Why Landschaftsschutzgebiet Diedersdorfer Heide und Großbeerener Graben stands out
The protected landscape is most recognized for its role as a large, contiguous buffer of open agricultural land, woodland, and wetland habitat along the southern edge of Berlin. It preserves a mosaic of sandy heath fields, pine forest, wet meadows along the Mahlower Seegraben and Nuthegraben, and the Natura 2000-listed Genshagener Busch, providing both ecological continuity and accessible countryside within a strongly metropolitan region. Equally distinctive is its hydrological framework: an 19th-century system of drainage ditches that channeled excess water from Berlin's former sewage farms into the Nuthe, and which today forms the structural backbone for wetland, meadow, and aquatic habitat restoration. The protected area thus stands out as a landscape where cultural drainage history and modern habitat management actively overlap.
Landschaftsschutzgebiet Diedersdorfer Heide und Großbeerener Graben history and protected-area timeline
The landscape protected today as the Landschaftsschutzgebiet Diedersdorfer Heide und Großbeerener Graben has been shaped by drainage and land-use pressures that long predate its formal designation. Throughout the 19th century, the area's network of ditches served a critical infrastructure function, carrying surplus water from Berlin's Rieselfelder, the historical sewage irrigation fields, into the Nuthe river. By the 1960s, intensified melioration work along the Großbeerener Graben further reorganized the local hydrology in favor of agriculture.
Modern statutory protection began on 27 February 1998, when the Brandenburg state government established the landscape protection area as a unified framework combining ecological preservation with continued productive use. Subsequent amendments followed: on 10 January 2002 and on 23 June 2005, smaller parcels were formally removed from the protected zone to accommodate specific land-use adjustments. A further amendment on 3 February 2014 allowed the protection purposes to be set aside for areas covered by approved building plans, subject to ministerial consent.
A major infrastructural event came with the construction of the four-lane Landesstraße 76, an east-west connecting road opened in 2010, running from Potsdam via Teltow to Mahlow and on to Schönefeld. Because this route cuts fully through the protected landscape, the project was paired with a comprehensive mitigation package. This package included a dedicated wildlife overpass, an amphibian crossing, continuous game-protection fencing along the route, reforestation of roughly 17 hectares with mixed deciduous species, the planting of around 400 deciduous and fruit trees along roads and paths, shrub planting on central reservations and embankments, a bridge over the Mahlower Seegraben functioning as an irrigation transition, a bridge for an agricultural access road, and about two kilometers of new service tracks to support the area's farmers and foresters.
Landschaftsschutzgebiet Diedersdorfer Heide und Großbeerener Graben landscape and geographic character
The landscape of the protected area reflects the typical post-glacial character of the Teltow plateau south of Berlin, with sandy, gently undulating terrain shaped both by natural processes and by long-standing cultivation. The view from the Berlin border sweeps across the open Osdorfer Feldflur, a wide agricultural plain dotted with the small Osdorfer Wäldchen woodland patch, before the relief subtly shifts toward the slightly more sheltered zone of the Diedersdorfer Heide in the center.
Water is one of the strongest organizing elements of the terrain. The Mahlower Seegraben runs through the heart of the area, and the Nuthegraben separates the Genshagener Busch from the Diedersdorfer Wiesen further south. Together with smaller ditches, these waterways have both drained and, in modern management terms, structured the land, defining where wet meadows, floodplain soils, and reed-influenced vegetation persist and where drier, sandy-influenced heath and woodland take over.
Forest cover is dominated by pine stands, many of which are slated for gradual conversion into more diverse mixed deciduous woodland. Open fields and dry grassland pockets break up the otherwise wooded and farmed matrix, while small embanked features, road cuttings, and infrastructure crossings form more recent - but increasingly vegetated - features of the terrain. The ring of transport corridors around the area, including the A10 motorway to the south, the B101 to the west, and the Berlin-Dresden railway to the east, gives the protected landscape a clearly defined perimeter within an otherwise heavily networked region.
Landschaftsschutzgebiet Diedersdorfer Heide und Großbeerener Graben ecosystems, habitats, and plant life
Ecologically, the protected landscape functions as a large, ecologically varied buffer against the southern expansion of Berlin, combining dry, sandy-influenced habitats with persistent wet zones. Dry grassland fragments have been singled out for active preservation, while pine-dominated forest stands are being progressively converted into mixed deciduous woodland to broaden structural diversity. The water system, centered on the Mahlower Seegraben and Nuthegraben, supports wet meadows and floodplain soils that are being deliberately renaturated after decades of melioration.
The most ecologically concentrated sub-area is the Genshagener Busch, which is recognized as both a Flora-Fauna-Habitat site and a Natura 2000 zone under European Union habitat legislation. Its roughly three square kilometers form the core of the area's biodiversity interest, tying local habitat management into broader transboundary ecological networks. Adjacent and embedded nature reserves such as the Glasowbachniederung, Torfbusch, and the nearby Naturschutzgebiet Zülowgrabenniederung extend the ecological context outward, creating a chain of wetland and woodland habitats along the Brandenburg side of the Berlin-Brandenburg interface.
Landschaftsschutzgebiet Diedersdorfer Heide und Großbeerener Graben wildlife and species highlights
Wildlife interest in the protected area concentrates along the network of ditches, wet meadows, scrub edges, and the Genshagener Busch forest patch. Birdlife is notably diverse for a peri-urban protected landscape, with characteristic species including the common crane, nightingale, great tit, willow warbler, yellowhammer, and great spotted woodpecker documented in or near the area. The presence of the crane in particular underscores the wetland value of the Mahlower Seegraben and the surrounding open meadows.
The combination of forest interior, edge habitats, and managed grasslands supports a mix of woodland and farmland bird species, while amphibians benefit from specific crossing infrastructure built into the Landesstraße 76, which cuts through the protection zone. The area is also crossed by the Berliner Mauerweg and the Berliner Nord-Süd-Weg, both of which bring regular human presence into otherwise quiet habitat zones, reinforcing the importance of well-designed wildlife crossings and game fencing for maintaining safe passage for larger mammals.
Landschaftsschutzgebiet Diedersdorfer Heide und Großbeerener Graben conservation status and protection priorities
From a conservation perspective, the protected area's importance lies in its institutional embedding and its blend of statutory protection with active management. As a designated Landschaftsschutzgebiet under Brandenburg law and as host to a Natura 2000 Flora-Fauna-Habitat site within the Genshagener Busch, it operates within both regional and European conservation frameworks. It is administered by the federal nature conservation authority, which coordinates its management across multiple municipalities.
Its conservation objectives are explicit and wide-ranging: maintaining the functional integrity of the natural balance of the landscape, preserving the diversity, character, and beauty of both natural and culturally shaped features, ensuring the sustainability of its role as a recreational resource for the Berlin conurbation, and steering land use toward nature-compatible and sustainable practices. These objectives translate into concrete actions such as renaturating existing water bodies, developing near-natural floodplain soils along streams, conserving dry grassland remnants, allowing sustainable recreational use under appropriate conditions, and gradually replacing pine monocultures with mixed deciduous forest.
Infrastructure mitigation, above all along the Landesstraße 76 corridor, has become an integral part of conservation practice in the area, with wildlife overpasses, amphibian crossings, protective fencing, new mixed forest, and structural planting along embankments helping to maintain ecological functionality even where the landscape is fragmented by transport routes.
Top sights and standout views in Landschaftsschutzgebiet Diedersdorfer Heide und Großbeerener Graben
The protected area's standout qualities are its sheer scale as a peri-urban cultural landscape, the unusual depth of its hydrological heritage, and the layered network of European and regional protection statuses operating within a single territory. Within a short distance of central Berlin, it preserves tens of square kilometers of working heathland, woodland, and meadow whose management is anchored in 19th- and 20th-century drainage history but actively redirected toward ecological recovery.
The Genshagener Busch adds European Natura 2000 significance, while the mitigation measures around Landesstraße 76 demonstrate how modern infrastructure and nature protection can be reconciled through wildlife crossings, habitat restoration, and forest conversion. The result is a protected landscape that is simultaneously agricultural, ecological, recreational, and infrastructural, reflecting the complex pressures shaping the Berlin-Brandenburg interface.
Best time to visit Landschaftsschutzgebiet Diedersdorfer Heide und Großbeerener Graben
The landscape is broadly accessible year-round, but its character shifts notably with the seasons. Spring and early summer bring active birdlife, including visible cranes and nightingales along the wet meadows of the Mahlower Seegraben, alongside fresh growth in woods and along path edges that makes the area especially attractive for walking. Late spring is also when dry grasslands and field margins display their richest floral variety, including characteristic species documented within the protection zone.
Autumn offers quieter conditions, softer light across the open Osdorfer Feldflur, and harvest-season activity in the agricultural parts of the protection area. Winter reveals the broader spatial structure of the landscape, with the mix of open fields and pine-dominated woodland clearly visible, and is a good time for observing larger gatherings of cranes and other seasonal bird movements. Throughout the year, the long-distance trails crossing the area, including the Berliner Mauerweg, the Berliner Nord-Süd-Weg (one of Berlin's 20 green main routes), the Teltower Dörferweg, and the Natura Trail Genshagener Busch, allow visitors to experience the landscape under varying conditions.
