Why Sandsteinbrüche am Burzelberg bei Frau-Nauses stands out
The reserve is best known for combining a striking Odenwald Buntsandstein quarry landscape with one of southern Hesse's most important inland cliff habitats for breeding raptors. The roughly 25 to 30 metre main quarry wall, together with three smaller pits, provides the vertical rock structure targeted for the reintroduction and continued breeding of peregrine falcons and the more recently established breeding of Eurasian eagle-owls. Beyond the birdlife, the area is valued as a compact example of post-industrial landscape recovery, where abandoned red sandstone quarrying has given way to near-natural forest mantle, heat-loving scrub-edge communities, and protected cliff habitat. The site is also the locality that connects the regional sandstone quarrying heritage of the Odenwald with modern EU-level conservation under the Natura 2000 network.
Sandsteinbrüche am Burzelberg bei Frau-Nauses history and protected-area timeline
The sandstone at the Burzelberg was extracted as part of the long tradition of quarrying the regionally characteristic Odenwald Buntsandstein, a red Lower Triassic sandstone that has been worked across this part of Hesse for many generations. The quarry itself was active into the 1980s, after which operations were halted. The closure of the pit allowed the surrounding forest to encroach and the rock faces, scree, and fringes to develop towards a more natural state over the following decade.
Even before formal protection, the abandoned quarry was already known locally as a climbing area under the name Silberwald. Conservation recognition came in the form of a Hessian nature-protection ordinance dated 14 December 1994, which established the Naturschutzgebiet "Sandsteinbrüche am Burzelberg bei Frau-Nauses" under the code 1432 and registered it as WDPA-ID 165318. The protection order explicitly listed the natural forest mantle, the neighbouring warm-loving fringe communities, the cliff faces for their geological, natural-history and landscape value, and cliff-nesting raptors, especially peregrine falcons, as targets of management.
In 2008 the area gained an additional layer of conservation status when a near-identical sub-area became part of the Natura 2000 site "Felswände des nördlichen Odenwaldes", an EU Bird Directive area (6119-402) covering cliff walls across the northern Odenwald. Through the 1990s and 2000s the site became a regionally notable raptor breeding location, and from 2009 the quarry has hosted regular Eurasian eagle-owl broods as well.
Sandsteinbrüche am Burzelberg bei Frau-Nauses landscape and geographic character
The landscape of the reserve is shaped almost entirely by the interplay between former quarrying and forest regeneration along the northern edge of the Sandstein-Odenwald. The Burzelberg site carries the visual signature of Odenwald Buntsandstein: warm reddish-orange rock tones, sharp jointed faces, and a quarry floor littered with rubble that has slowly been recolonized by vegetation. The main working face rises about 25 to 30 metres above the pit floor, and three smaller pits are distributed around it, some already substantially overgrown.
Around the quarry walls sits a near-natural forest mantle, partially withdrawn from active forestry, in which scattered pines and birch trees have established themselves even on the rock itself. The transition from woodland to cliff is marked by heat-loving scrub and fringe communities, which are an integral part of the protected mosaic rather than a fringe feature. Outside the reserve, the terrain continues as part of the broader forested Odenwald hills, while the busy B45 corridor passes at the foot of the slope, making the quarry a quiet green break in an otherwise road-influenced landscape.
Sandsteinbrüche am Burzelberg bei Frau-Nauses ecosystems, habitats, and plant life
Ecologically, the reserve is best understood as a small-scale but unusually rich mosaic of three interconnected habitats: vertical sandstone cliff, warm-climate scrub and forest edge, and near-natural mixed forest. The cliff itself provides nesting ledges, sheltered cracks, and bare rock surfaces that are scarce in much of the surrounding low mountain range. The forest mantle above the quarries has been partly taken out of active forestry, allowing a more natural stand structure with mature trees, deadwood, and an understorey that supports species associated with old woodlands.
The transition zone between forest and cliff is especially important. Here, heat-loving fringe communities and scrub margins have established on the well-drained, sun-exposed sandstone substrate, providing a habitat type that is generally uncommon in the more wooded Odenwald. The combination of cliff, rubbly quarry floor, scrubby margins, and intact forest in a compact area gives the site an ecological profile that punches well above its modest 19.46 hectare footprint, as recognized by its overlap with the Natura 2000 site "Felswände des nördlichen Odenwaldes".
Sandsteinbrüche am Burzelberg bei Frau-Nauses wildlife and species highlights
Wildlife interest in the reserve is concentrated on cliff-nesting birds of prey, which are the headline feature of the site's biological value. The quarry has a documented record of successful peregrine falcon (Wanderfalke) breeding in the period from 1995 through 2010, and although individual peregrines continued to use the site afterwards, no successful broods were recorded in the year covered by the source. Since 2009 the quarry has also supported breeding pairs of the Eurasian eagle-owl (Uhu), making the site one of the more inland cliff-breeding raptor locations in southern Hesse.
The surrounding forest mantle and warm-clime fringe communities provide the supporting habitat for these cliff specialists, offering cover in mature trees, sheltered roosting spots, and a prey base drawn from the broader Odenwald forest. The management goal of preserving and actively enhancing cliff habitat structures is explicitly aimed at securing these raptor populations for the long term.
Sandsteinbrüche am Burzelberg bei Frau-Nauses conservation status and protection priorities
The conservation significance of Sandsteinbrüche am Burzelberg bei Frau-Nauses rests on the unusual combination of geological heritage and high-quality cliff habitat, both of which are rare in the regional landscape. Designated in December 1994 as a Hessian Naturschutzgebiet, the site protects a mosaic of near-natural forest mantle, heat-loving scrub-edge communities, and former quarry cliff faces, recognizing all three as integrated parts of the conservation target rather than as incidental features.
Since 2008 the reserve has also been part of the EU Natura 2000 network through the Bird Directive site "Felswände des nördlichen Odenwaldes" (6119-402), giving it trans-regional importance as one of the cliff locations protecting bird species of European conservation interest. The reserve's management actively aims at habitat structures suited to peregrine falcons and U data shows that this management has worked: the quarry supported documented peregrine breeding across multiple years and has become a regular eagle-owl breeding site.
Because the reserve lies directly beside the busy Bundesstraße 45 and is also used as a seasonal climbing area, conservation management is as much about limiting disturbance as about protection on paper. Climbing has been restricted to a narrow parcel of land and a defined season, and in years with sensitive raptor broods full closure for climbers has been recommended to reduce the risk of disturbance to nesting peregrines and eagle-owls.
Sandsteinbrüche am Burzelberg bei Frau-Nauses cultural meaning and human context
The most visible piece of cultural context at the Burzelberg is not traditional land use but a more recent recreational tradition. Before the site received its 1994 nature-protection status, the abandoned quarry was already established in the 1980s as an inland climbing area under the name Silberwald, and sport climbing has remained a regulated, partial use of the reserve since. That climbing heritage continues today under strict seasonal and spatial limits.
More broadly, the site carries the regional cultural imprint of Odenwald Buntsandstein quarrying, an extractive tradition that shaped the area's villages, roads, and built heritage for generations. The Burzelberg quarries are a small but characteristic trace of that history, now reinterpreted both as a piece of geological and industrial heritage and as a protected nature area within the modern conservation framework of Hesse and the EU.

A redevelopment of an abandoned Odenwald Buntsandstein quarry into a formal nature reserve, with the 25 to 30 metre main quarry wall as the dramatic centrepiece and three smaller pits completing the geological story.
The site's main wildlife highlights are its peregrine falcon breeding record spanning many years and the more recent establishment of Eurasian eagle-owls, both supported by active habitat management aimed at cliff-nesting raptors.
The reserve's dual conservation status, at once a Hessian Naturschutzgebiet and part of the EU Natura 2000 "Felswände des nördlichen Odenwaldes", gives it a layered level of protection that is unusual for a site of its modest size. The locally protected climbing tradition at the former Silberwald quarry adds a small but distinctive cultural-recreational dimension to the place.
