Why Medláněcké kopce stands out
Medláněcké kopce is known above all for hosting one of the northernmost populations of the large-flowered pasqueflower (Pulsatilla grandis) in the Czech Republic, together with a dry, steppe-like grassland community that harbors unusually thermophilic flora and insects on the northern edge of Brno. The reserve also marks the northernmost known occurrence of the southern festoon butterfly (Zerynthia polyxena) and the northernmost known site in the country for narrow-leaved sedge (Carex stenophylla). Its other defining trait is the way it preserves dry grassland and rocky outcrops right inside a large urban area. Quartzite-like metabasite rocks of the Brno massif break through the surface, with loess on the sheltered eastern slopes, creating conditions for rare steppe species that would otherwise be associated with much warmer, more southern landscapes in Moravia or central Europe.
Medláněcké kopce history and protected-area timeline
The hills that now make up Medláněcké kopce were administratively part of the Medlánky cadastral area until the 1960s, which is why both are referred to under the collective name "Medláněcké kopce" even though they now lie on different cadastral territories.
As with many European dry-grassland reserves, the biological value of these slopes is closely tied to traditional, low-intensity land use. Open rock and steppe vegetation survived precisely because the dry, shallow soils over metabasite bedrock were unsuitable for intensive agriculture, allowing a thermophilic flora and insect fauna to persist into the era of modern nature protection.
Formal protection came relatively late, in the late twentieth century, when the site was declared a přírodní památka (natural monument) on 1 January 1988. Since then it has been administered by the Jihomoravský kraj regional authority, acting through its nature conservation office, and has remained a focal site for studying the survival of steppe biota within an urbanized landscape.
Medláněcké kopce landscape and geographic character
The protected area consists of two hills rising modestly above the flat north-Brno plain. The smaller Medláněcký kopec reaches 322 meters in elevation, while the larger Střelecký kopec reaches 338 meters. Both hills have open, rocky summits and slopes with relatively shallow soils, giving them a distinctive steppe-like profile that contrasts sharply with the surrounding urban fabric of Medlánky and Královo Pole.
The underlying geology plays a decisive role in shaping this landscape. Metabasite rocks of the Brno massif, interspersed with granite porphyry, frequently break through to the surface, producing stony, sun-exposed outcrops. On the more sheltered eastern flanks, wind-deposited loess has accumulated, while the soils across the site include typical and eutrophic cambisols, rankers, and loess-based luvisols.
Because of this geological and topographic setting, the slopes retain a semi-open character with scattered shrubs, rocky patches, and herb-rich dry grassland rather than closed forest. The sky-line is broken by crags and small rock steps rather than tall trees, and from higher points the landscape opens westward and northward toward the broader Brno basin, where the reserve forms a small but very visible natural feature above the city.
Medláněcké kopce ecosystems, habitats, and plant life
Ecologically, Medláněcké kopce is a relict of the Central European steppe biome, surviving on warm, dry, and rocky substrates that would normally be associated with much more southerly landscapes. The vegetation is dominated by thermophilic dry grassland and open scrub, where exposed rock, thin soils, and a sunny, continental microclimate combine to create conditions for a distinctive plant and insect community.
The site is also part of a wider mosaic of dry habitats in this part of Brno, complementing the nearby Medláněcká skalka and Netopýrky nature monuments. The Medlánky airfield immediately south of the protected area supports an additional small population of European ground squirrels, so these hills effectively anchor a broader complex of urban-edge steppe habitat. This mosaic character means that the reserve is valuable not just in itself, but as a node within a network of dry-grassland patches that allow specialist species to persist across an otherwise heavily built-up landscape.
Medláněcké kopce wildlife and species highlights
Medláněcké kopce is particularly valued for its thermophilic insect fauna, which is unusually rich for a site so far north in Moravia. The hills mark the northernmost known occurrence of the southern festoon (Zerynthia polyxena) in the Czech Republic, and also host the swallowtail (Papilio machaon), the scarce swallowtail (Iphiclides podalirius), the bagworm moth Ptilocephala muscella, and the praying mantis (Mantis religiosa).
Reptiles recorded here include the sand lizard (Lacerta agilis), the slow worm (Anguis fragilis), and the smooth snake (Coronella austriaca), all of which are typical of warm, dry, open habitats. The bird life reflects the open, scrubby character of the site: the wryneck (Jynx torquilla), barred warbler (Sylvia nisoria), red-backed shrike (Lanius collurio), and golden oriole (Oriolus oriolus) have all been observed on or around the reserve.
The mammalian fauna is less prominent but includes the broader context of the Medlánky airfield colony of European ground squirrels (Spermophilus citellus), and the wider area provides habitat for bats whose roosting and foraging grounds are partly protected in the neighboring Netopýrky reserve.
Medláněcké kopce conservation status and protection priorities
Medláněcké kopce is protected as a přírodní památka, corresponding to IUCN Category IV (habitat/species management area). Its primary conservation objective is the long-term survival of a thermophilic plant and insect assemblage typical of the Central European steppe biome, and in particular the large-flowered pasqueflower (Pulsatilla grandis), which is the headline species of the reserve.
The area also has protective value because it preserves dry, rocky, and loess-based habitats in a region where such environments are increasingly fragmented by urban growth. By maintaining open rock and dry grassland structure, the site supports a group of narrowly distributed plants, including the northernmost Czech population of narrow-leaved sedge (Carex stenophylla), and the northernmost Czech site for the southern festoon butterfly.
From a conservation planning perspective, the reserve is an important node within a small network of urban-edge nature monuments in northern Brno. Its ecological function depends on the persistence of the surrounding low-intensity land use, particularly on the Medlánky airfield grasslands that harbor the European ground squirrel colony, and on the integrity of the nearby Medláněcká skalka and Netopýrky sites.
Medláněcké kopce cultural meaning and human context
The hills have a modest but tangible place in the cultural and administrative geography of Brno. Until the 1960s, both the Medláněcký kopec and Střelecký kopec belonged entirely to the Medlánky cadastral area, and the collective name "Medláněcké kopce" has been retained even after administrative boundaries shifted. Střelecký kopec in particular carries local toponymic significance, echoing the historical presence of shooting-related activity on this northern fringe of the city.
More broadly, the reserve reflects a long tradition of amateur natural history in and around Brno, with botanists and entomologists documenting its unusually thermophilic flora and butterflies for decades before its formal protection in 1988.
Top sights and standout views in Medláněcké kopce
Steppe-like vegetation on metabasite and loess soils in the midst of Brno; large-flowered pasqueflower (Pulsatilla grandis) as the flagship species; the northernmost known Czech sites for narrow-leaved sedge and the southern festoon butterfly; thermophilic butterflies including swallowtail, scarce swallowtail, and praying mantis; a small network of urban-edge dry-grassland reserves including Medláněcká skalka and Netopýrky; and a wider mosaic of dry habitats connected to the ground-squirrel colony on the Medlánky airfield.
Best time to visit Medláněcké kopce
Late spring is the most rewarding season to visit Medláněcké kopce, when the large-flowered pasqueflower is in bloom and butterfly activity on the warm, south-facing slopes is at its highest. Early summer also brings rich displays of thermophilic grassland flowers and active reptiles along the rocky edges. Autumn visits can be quieter but still attractive; visitors should expect the dry, sun-exposed character of the site to be most intense between roughly May and July, when the steppe-like flora is most visible and the insect fauna most active.
