The Weyrichsbruch

The Weyrichsbruch - A habitat and refuge for rare animals and plants with an enchanting atmosphere in the core zone of the Saar-Hunsrück Nature Park.

- A spring-fed bog in the high forest -

The Weyrichsbruch, located in the Osburg high forest and known locally as a raised bog, covers almost 7 hectares and is a spring-fed bog that has been preserved in a near-natural state and is owned by the state of Rhineland-Palatinate. All necessary maintenance work in the spring-fed bog is therefore carried out at the behest of the responsible Hochwald Forestry Office, based in Dhronecken. The Osburg high forest lies within the core zone of the Saar-Hunsrück Nature Park.
A 300-meter-long boardwalk, constructed of spruce logs, was first built in 1968/69 along the western edge of the spring-fed bog. This boardwalk allows forest visitors to traverse the slope without having to disturb the entire valuable biotope.
Today, this boardwalk is not only part of the 10-kilometer Rösterkopf circular hiking trail but is also integrated into the premium hiking trail "Saar-Hunsrück-Steig".

On the History and Development of the Weyrichbruch:

This area of ​​the Hunsrück forest is geologically part of the southwestern Rhenish Massif and its development dates back to the Lower Devonian period (approximately 400 million years ago). The formation of the slope bogs began during the Early Subatlantic period, around 3000 years ago, as determined through extensive vegetation surveys. In this part of the Hunsrück, a layer of quartzite rock up to approximately 1000 meters thick can be expected, in whose cavities groundwater collects, emerging from springs – often migratory springs – with excellent water quality. Until the 18th century, the quartzite ridges of the Hunsrück were surrounded by numerous spring-fed or slope bogs. However, in order to improve the forestry use of these small bogs, they were drained by constructing extensive drainage systems and reforesting the bogs with spruce trees. The drainage ditches, originally constructed between 1850 and 1870, are still clearly visible today.

Between 1935 and 1938, the existing ditch system was further expanded and maintained.
The herringbone pattern of the drainage ditches was intended to facilitate reforestation with coniferous trees. The last remaining old spruce trees from the reforestation efforts in the Weyrichsbruch were removed in 1998, so that the unwanted conifers that were crowding out the downy birch are no longer present. In the two subsequent years, weirs made of larch logs were installed in the drainage ditches to slow the water runoff and simultaneously raise the water table in the fen. These ditch barriers require ongoing monitoring, maintenance, and supplementation to ensure the long-term stability of the spring-fed fen, which remains in a near-natural state. In the area of ​​the widespread bracken fern, which represents an establishment barrier for other plant communities, 800 young downy birches were planted by the Hochwald Forestry Office.

Accessible all year round - caution is advised, especially in winter, due to the risk of slipping!
