Laubwälder am Mun-Depot: Mapping the Geography of this North Rhine-Westphalia Nature Reserve

The reserve is best known for protecting a predominantly deciduous forest that has developed on a former military ammunition depot in the Bergisches Land. Its most distinctive ecological role is as a mating area and habitat for bats, with the greater mouse-eared bat (Myotis myotis) highlighted as the key species of conservation concern. It also stands out as a notable example of post-military land use in the Oberbergischer Kreis, where a cleared and vandalised Bundeswehr site was formally brought under nature protection in 2014 rather than being sold or redeveloped for other purposes such as a planned forensic clinic.

The land that now forms Laubwälder am Mun-Depot was originally used as a military ammunition depot by the Bundeswehr, operating under the designation LwMunDp82. The depot was cleared and vacated in 2005, ending its active military role.

After the military withdrawal, the unused site experienced vandalism and physical damage during the years that followed. In autumn 2011, the German Federal Office for Property Management (Bundesamt für Immobilienaufgaben) began pursuing the sale of the depot, and in 2014 there was public discussion about constructing a forensic clinic on the grounds. Local opposition, including from the citizens' initiative Bürgerinitiative Reichshof e.V., helped keep the site out of those plans.

In April 2014, the council of the Oberbergischer Kreis resolved, within the framework of the landscape plan for the Wiehltalsperre, to designate the area as a nature reserve (Naturschutzgebiet), under the official identifier GM-130. The explicit purpose of the designation was to secure and develop the predominantly deciduous woodland on the site as a habitat and mating area for bats, with particular reference to the greater mouse-eared bat. This protection order gave the former ammunition depot a new, long-term function as an ecological reserve rather than a development or military site.

The landscape of Laubwälder am Mun-Depot is shaped by the gently rolling topography typical of the Bergisches Land, an upland region between the rivers Sieg, Agger, and Wupper. The reserve sits at roughly 50.92 degrees north latitude and 7.75 degrees east longitude, within the broader catchment that drains toward the Wiehl reservoir system.

Rather than dramatic peaks or deep valleys, the site offers the modest, forested relief that characterises much of the Oberbergischer Kreis. The terrain is dominated by broadleaf woodland cover that developed after the site was cleared of its military use, with the surrounding regional landscape continuing into neighbouring protected areas along stream valleys, slopes, and reservoir margins.

Part of the reserve's landscape significance lies in its infrastructure legacy: traces of its former function as a Bundeswehr ammunition depot are still embedded in the site, and the 2013 deforestation mentioned in the source refers to the clearing associated with that military history rather than active forest management of the current reserve.

Ecologically, Laubwälder am Mun-Depot centres on broadleaf forest rather than mixed or coniferous woodland. The protection order specifically aims at preserving and further developing an area dominated by deciduous tree species, creating a structurally diverse, broadleaf-dominated habitat that can support sensitive woodland fauna.

The site's designation as an IUCN Category IV habitat and species management area signals that the nature of the reserve is actively managed to maintain conditions for target species, rather than being left as strict wilderness. Deciduous canopy, the availability of mature trees, and the structural complexity that comes from a former military site now partly reclaimed by forest succession all contribute to the habitat character of the area.

Within the Oberbergischer Kreis, this reserve sits among a wider cluster of protected forests, stream valleys, and slopes that together maintain connected woodland and bat habitat across the district.

The wildlife profile of Laubwälder am Mun-Depot is closely tied to its bat fauna. The reserve's formal purpose highlights its role as a mating area and habitat for bats, and the greater mouse-eared bat (Myotis myotis) is the species most prominently associated with the site's conservation value.

Myotis myotis is a species that depends on structurally complex deciduous forests with open ground for foraging and on suitable roosting environments, which aligns well with the post-military character of this formerly cleared site. While the source focuses on bats as the headline wildlife interest, the broader deciduous forest setting also makes the reserve relevant for woodland birds and other forest-dwelling fauna typical of the Oberbergisches Land.

The species emphasis in the protection order reflects a deliberate conservation choice: rather than managing for general biodiversity alone, the reserve is maintained with bat habitat needs and the long-term continuity of deciduous woodland as guiding priorities.

Conservation significance at Laubwälder am Mun-Depot arises from a combination of habitat protection and land-use redirection. By formally designating the former ammunition depot as a nature reserve in 2014, the Oberbergischer Kreis secured a predominantly deciduous forest area from sale, vandalism, and competing development pressures, including the proposed forensic clinic that had been discussed for the site.

The reserve falls under the regional landscape plan (Landschaftsplan) for the Wiehltalsperre, integrating it into a broader planning framework that manages connected habitats across the district. Its IUCN Category IV classification situates it within the wider national and international network of habitat and species management areas, recognising that the site is actively shaped to support specific conservation targets.

The most explicit conservation target is the greater mouse-eared bat (Myotis myotis), a species whose regional populations depend on protected deciduous forest and suitable roosting environments. By focusing on bat habitat and the continuity of broadleaf woodland, the reserve contributes to maintaining functional habitat for bats in the Oberbergischer Kreis and adds to the cumulative ecological value of the district's network of protected forests and valleys.

The cultural context of Laubwälder am Mun-Depot is closely tied to the post-Cold War reshaping of military land in Germany. The site's transformation from an active Bundeswehr ammunition depot (LwMunDp82), cleared in 2005, to a protected forest area reflects broader shifts in how former military properties have been repurposed in rural North Rhine-Westphalia.

Local civic engagement also forms part of the site's recent history: the citizens' initiative Bürgerinitiative Reichshof e.V. publicly opposed the proposed forensic clinic on the site, helping to preserve the area from redevelopment. Together, the military past and the community-driven conservation decision give the reserve a distinctive cultural character within the Oberbergischer Kreis.

Laubwälder am Mun-Depot combines a compact 22.7-hectare size with an uncommon land-use story: a former Bundeswehr ammunition depot that was cleared in 2005 and then legally secured as a nature reserve in April 2014, after local opposition helped prevent redevelopment plans such as a forensic clinic.

Its defining highlights are the predominantly deciduous broadleaf woodland, its classification as an IUCN Category IV habitat and species management area, and its explicit designation as a mating area and habitat for bats, especially the greater mouse-eared bat. As part of the landscape plan for the Wiehltalsperre and the wider protected-area network of the Oberbergischer Kreis, the reserve adds a bat-focused forest patch to a district already rich in protected valleys, slopes, and reservoir-side habitats.

As a small, forested nature reserve without public visitor infrastructure described in the source, Laubwälder am Mun-Depot is best approached as a quiet landscape for low-impact, informed visits rather than a mainstream sightseeing destination.

Seasonally, late spring and summer offer the most active bat fauna and the fullest deciduous canopy, while autumn can highlight the broadleaf character of the woodland as the leaves change. Because the site's identity is tied to bats and to deciduous forest structure, visits oriented around listening for bat activity at dusk, or simply experiencing the mature broadleaf woodland in different seasons, are likely to be more rewarding than visits focused on viewpoints or visitor centres. Specific operational access, guided events, or seasonal closures are not described in the source and should not be assumed.
