Hádecká planinka National Nature Reserve

The Hádecká planinka reserve lies on the southern part of the Hády plateau between Brno and Bílovice nad Svitavou, in the Jihomoravský kraj – South Moravian Region. F3615The national nature reserve was declared in 1950 on an area of 79.5 ha.

The territory is predominantly built of Devonian and Lower Carboniferous limestones with a rich fossil fauna. The typical fossils found here are ostracodes, brachiopods, trilobites, corals, cephalopods and conodonts. Small karren can be found in the Šumbera scarp area.

The thermophilous vegetation on the Hády plateau is primarily represented by white or pubescent oak stands with white oak (Quercus pubescens), Turkey oak (Quercus cerris) and sessile oak (Quercus petraea) with wild service tree (Sorbus torminalis). Typical species in the rich shrub layer include bladder nut (Staphyllea pinnata), Cornelian cherry (Cornus mas) and barberry (Berberis vulgaris). Notable species in the herb layer are the St. Bernard´s lily (Anthericum ramosum), purple gromwell (Lithospermum purpurocaeruleum) and burning bush (Dictamnus albus). The forest glades and sunny fringes exhibit a high species diversity with cushion spurge (Euphorbia polychroma), bastard balm (Melittis melissophyllum), Hungarian iris (Iris variegata), the feather grass Stipa pennata, great pasque flower (Pulsatilla grandis), burnet rose (Rosa  pimpinellifolia) and the critically-endangered the bugloss Echium maculatum.

Shadier localities are vegetated with a tree layer of hornbeam (Carpinus betulus), sessile oak and pendunculate oak (Quercus robur) with cornelian cherry and dogwood (Cornus sanguinea). In the herb layer we can find spring pea (Lathyrus vernus), cowslip (Primula veris), lungwort (Pulmonaria officinalis), the swallowwort (Vincetoxicum hirundinaria), the highly-endangered burnt-tip orchid (Orchis ustulata) and others.

  On the colder north and north-west slopes (e.g. under the Šumbera scarp rocks) the predominant trees are large-leaved limes (Tilia platyphyllos), with scattered small-leaved lime (Tilia cordata), Norway maple (Acer platanoides) and sycamore (Acer pseudoplatanus). In the herb layer we can find mezereon (Daphne mezereum), baneberry (Actaea spicata), herb Robert (Geranium robertianum) and others. The critically-endangered yellow figwort (Scrophularia vernalis) also grows here.

Among the endangered butterfly species which live here we can include oak hawk-moth (Marumba quercus) and rarely southern rustic (Rhyacia lucipeta). Our largest beetle – the stag beetle (Lucanus cervus) may catch your eye. Many small songbirds nest in the reserve and the most common of these are the great tit (Parus major), marsh tit (Parus palustris), chiffchaff (Phylloscopus collybita) and the blackcap (Sylvia atricapilla). The most common of the small mammals here are the bank vole (Clethrionomys glareolus) and the wood mouse (Apodemus sylvaticus).

The limestone surface of the Hády plateau has been influenced by human activity for many centuries. On the territory of today’s NNR, limestone was quarried and the forest stands were influenced by logging and cattle grazing. The unity of the forest cover was interrupted by the construction of a radio communication tower with its access road. The proximity of the reserve to the centre of Brno brings large numbers of walkers and cyclists to the area and they often disrespect regulations limiting access to the forest stands and leave litter in the reserve. The themed nature trail entitled “Hády and the Říčky valley” starts near the Velká Klajdovka restaurant and informs visitors about the significance of the reserve and issues concerning nature protection.
