Rohrsee von Rehbach Nature Reserve: Mapped Protected Landscapes in the Sandstein Odenwald

Rohrsee von Rehbach has been formally protected as a Naturschutzgebiet since November 24, 1986, when it was designated under the identifier 1437007. The ordinance establishing the reserve recognized the wetland's value as a refuge for plants and animals in an otherwise predominantly sandstone and forested landscape. A supplementary ordinance on September 20, 1993 amended and refined the protection framework, suggesting ongoing adjustments to the management of the site. Beyond these key administrative milestones, the pond itself is described as artificially created, indicating that the open water element of the habitat is the result of deliberate historical land management rather than a purely natural feature.

The reserve lies in a gently rolling section of the Sandstein-Odenwald, where the broader landscape is shaped by sandstone bedrock, mixed forest cover, and small stream valleys. Within this setting, the protected area itself is defined by soft, low-lying terrain dominated by open water and moist ground. The central feature is a shallow, flat-bottomed pond with a marked reed belt (Schilfgürtel), bordered by stands of sedges and wet meadows.

The Rehbach stream, a left-hand tributary of the Mümling, flows through the area, providing hydrological connection between the pond and the wider drainage network. Elevations within the reserve range from roughly 276 to 288 meters above sea level, and the gentle topography allows water to persist at the surface, supporting the continuous presence of wetland vegetation. To the north, the Bundesstraße 47 forms a clear linear boundary, while the surrounding hillsides remain forested in the typical Odenwald manner.

Rohrsee von Rehbach preserves a wetland habitat complex that is unusual in the Sandstein-Odenwald. The protected area combines a shallow artificial pond, extensive reed (Röhricht) stands, sedge communities, and adjacent wet meadows, creating a layered habitat that includes open water, emergent vegetation, marshland, and seasonally moist grassland.

This habitat mosaic supports a mix of aquatic, marsh-loving, and grassland species in close proximity, which is ecologically rare in a region dominated by dry sandstone soils and beech or mixed forests. The intentional inclusion of the artificial pond adds an open-water component that would otherwise be largely absent in this landscape, while the reed belt and sedge stands provide the structural complexity needed for nesting cover and foraging habitat.

The reserve's particular value lies in its role for waterbirds. The shallow pond, the surrounding reed belt, and the wet meadows together function as a breeding, feeding, and resting area for a range of bird species, some of which are considered rare or threatened. By providing this combination of open water for waterfowl, dense reeds for nesting cover, and adjacent moist meadows for foraging, the site acts as a compact bird refuge within a landscape that generally offers fewer wetland opportunities.

Rohrsee von Rehbach is designated as a Naturschutzgebiet under German nature conservation law and is classified internationally as an IUCN Category IV Habitat/Species Management Area. Its protection focuses specifically on the preservation of a wetland biotope and on maintaining viable habitats for a broad range of plant and animal species, with particular emphasis on waterbirds using the site for breeding, feeding, and resting.

Because wetland conditions are scarce in the Sandstein-Odenwald, the reserve has a disproportionate role in maintaining regional biodiversity, supporting both aquatic and marsh-associated flora and fauna that would otherwise struggle to find suitable habitat in the surrounding sandstone terrain.

The reserve combines a shallow artificial pond with a pronounced reed belt and adjacent wet meadows in the heart of the sandstone Odenwald. It functions as an important breeding, feeding, and resting site for waterbirds in a region where wetland habitat is otherwise limited. With its compact area of about 15.57 hectares, it demonstrates how small, well-targeted protected sites can play an outsized role in regional biodiversity conservation.

The reserve can be experienced across the seasons, but late spring and early summer are typically the most rewarding times for observing reedbed and waterbird activity, when nesting, feeding, and vegetation growth are at their peak. Wet meadows and reeds also take on strong visual character in this period, while autumn can bring migratory use of the wetland as a resting and feeding stop.
