Vlkoš - statek Natural Monument: A Protected Wildlife Haven in the Olomouc Region of Czechia

Vlkoš, statek is known above all for its role as a protected summer roost of Geoffroy's bat, one of the more conservation-relevant bat species in Central Europe. The attic of a traditional farm building has supported a breeding and resting colony for at least two decades, surviving building works and everyday use of the structure. The site is a clear example of how cultural buildings, particularly older rural attics, can serve as critical wildlife refuges in heavily cultivated lowland landscapes.

The bat colony at the heart of Vlkoš – statek was first documented in 1998, when the presence of Geoffroy's bat in the attic of farmhouse number 25 was recorded. Even though residents continued to use the attic and the building underwent various modifications, the colony persisted in the structure.

By 2005, regular monitoring of the colony had been established, providing a clearer picture of its size and significance over time. These observations created the basis for seeking formal protection, and in 2013 the Regional Authority of the Olomouc Region declared the area as a natural monument, with effect from 31 December 2013. The designation made the colony's habitat the explicit subject of protection and anchored ongoing conservation management in a legally defined framework.

The natural monument occupies a very small, built footprint on the alluvial plain of the Morava River, within the wider Hornomoravský úval lowland. Geologically, the site sits on Quaternary sediments, with sandy loams and loamy sands at the surface overlying a deeper layer of gravelly sands. Although the protected object is a single building, geomorphologically the location belongs to the Středomoravská niva sub-unit, a flat alluvial plain shaped by long-term river action.

Around the village, agricultural land use dominates the visible landscape, but traces of the original natural setting survive as scattered fragments of floodplain forest, meadows, and wetland hollows. The broader mosaic of these surviving semi-natural patches, combined with the flat agricultural setting, defines the visual and ecological character of the area surrounding the monument.

Ecologically, Vlkoš – statek is defined less by the building itself and more by what it represents in the wider landscape context. The surrounding countryside retains fragments of floodplain forest, meadow communities, and wetland microhabitats, including flood-cycle pools that support mollusk and crustacean communities. These remnants stand in sharp contrast to the otherwise intensively farmed fields that dominate the immediate surroundings.

The protected object, the attic of the farmhouse, functions as a structural habitat, an artificial but ecologically vital roosting space. Warm summer attic conditions and the stability of a traditional rural building make it a particularly suitable summer refuge for a cave-dwelling bat species that has adapted to using such human-made structures in lowland agricultural regions where natural roosting options are scarce.

The defining wildlife feature of Vlkoš – statek is the summer colony of Geoffroy's bat that roosts in the attic of farmhouse number 25. Before the area received formal protection, the colony typically numbered between 80 and 130 individuals, making it a significant aggregation for the species in the regional context. Geoffroy's bat is generally associated with warm summer roosts in attics and similar structures and with foraging in habitats rich in arthropods, including the wooded floodplain mosaic that still partially survives around the village.

In the surrounding landscape, the surviving wetland hollows and floodplain fragments support additional wildlife communities, particularly mollusks and crustaceans adapted to periodically flooded pools. These groups, though less conspicuous than the bat colony, form part of the broader ecological character that the wider protected region is intended to support.

The primary conservation significance of Vlkoš – statek lies in safeguarding a small but ecologically critical roosting site for Geoffroy's bat, a species whose populations across Central Europe frequently depend on a limited number of suitable attic roosts. By protecting the building and its immediate surroundings as a natural monument, Czech authorities ensured that the colony's habitat cannot be altered without oversight and that monitoring and management obligations are linked to a specific site.

The site also intersects with European conservation priorities through its overlap with a Site of Community Importance designated within the Natura 2000 network, recognizing the bat population as part of the continent's broader effort to maintain biodiversity in agricultural landscapes. Together, these national and European designations frame Vlkoš – statek as a small but meaningful link in regional bat conservation, particularly in lowland areas where older farm buildings still offer viable alternatives to disappearing natural roosts.

Vlkoš – statek reflects the broader Czech tradition of small rural settlements embedded in intensively farmed lowland landscapes, where traditional farmhouses remain in active use. The protected building itself is a working part of this cultural fabric, occupied by residents who continue to live alongside the bat colony. This coexistence of everyday rural life and a protected wildlife feature is itself part of the area's character, illustrating how older Czech farm architecture continues to provide habitats that modern construction rarely replicates.

Vlkoš – statek stands out as a textbook example of building-based bat conservation in the Czech Republic, combining a tiny protected footprint with nationally and European-level nature protection designations. Its overlap with a Natura 2000 Site of Community Importance and its long-running monitoring program since 2005 give it a profile well beyond its size, and the site continues to demonstrate how traditional rural structures can host ecologically important bat colonies when properly recognized and protected.

As a small protected site focused on the conservation of a bat roost in a working farmhouse rather than a visitor destination, Vlkoš – statek does not have a developed public access profile. For naturalists interested in bat roosts in general, late spring through summer is typically the period when attic colonies of Geoffroy's bat are active, though access and observation at the specific site are subject to the requirements of the protected area and the residents of the building.
