Pouzdřany Steppe and Kolby Forest Botanical Excursion Guide Jan Roleček Department of Botany and Zoology Masaryk University Brno 2008 The Pouzdřany Steppe and Kolby Forest are parts of the National Nature Reserve Pouzdřanská step-kolby. The reserve is situated in southern Moravia above the village of Pouzdřany, about 25 km south of Brno and 6 km west of the town of Hustopeče. The complex of Pouzdřany Steppe and Kolby Forest represents one of the best-preserved remnants of subcontinental forest-steppe in the Czech Republic. Despite its limited area (47 ha), the nature reserve harbours much of the species richness of the now widely depleted Pannonian flora and fauna. The surrounding hilly landscape belongs to the southernmost outskirts of the Central Moravian Carpathians. From the hilltop of Pouzdřany Steppe, there is a great view of the Pavlov Hills across the lower Dyje valley, partly flooded by the Nové Mlýny reservoirs. Fringes of the Bohemian-Moravian Highlands enclose the view to the west, while lowlands of the Pannonian basin stretch to the southeast. The bedrock is mostly formed of Palaeogene calcareous claystones and sandstones of the Carpathian flysch, partly covered by Pleistocene loess. Climate of the region is relatively warm (mean annual temperature 9.1 C) and dry (mean annual precipitation 490 mm). Panoramic view of Pouzdřany Steppe, with a mosaic of dry grasslands and shrubs and with Kolby Forest on the plateau and shady slopes. White dots in the rear are individuals of Crambe tataria in bloom. The stripes of shrubs indicate former agricultural use of some of the grasslands. Photo J. Roleček. 2 The reserve comprises steep sunny slopes with dry grassland vegetation (Festucion valesiacae, Cirsio-Brachypodion pinnati), scattered shrubs and solitary trees, and a plateau and shady slopes with a mesic forest (Carpinion betuli). The species-rich dry grasslands of sunny slopes (Koelerio macranthae-stipetum joannis) are dominated by feather grasses (mostly Stipa pennata and S. pulcherrima), narrow-leaved fescues (Festuca valesiaca, F. rupicola), Koeleria macrantha or Carex humilis. Many drought-tolerant herbs and dwarfshrubs are admixed, e.g. Teucrium chamaedrys, Thymus pannonicus, Potentilla arenaria, Galium glaucum, Cytisus procumbens and Campanula sibirica. In disturbed (grazed, trampled, mown or formerly ploughed) places on deeper soils, rare species of continental or Pannonian steppe (Crambe tataria, Jurinea mollis, Astragalus exscapus) are particularly abundant. In more mesic sites, broad-leaved grasslands (Polygalo majoris-brachypodietum pinnati) with less drought-tolerant species (Peucedanum cervaria, Centaurea scabiosa, Geranium sanguineum, Adonis vernalis, Viola hirta and Orchis militaris) occur. Scattered shrubs and solitary trees include Crataegus monogyna, Prunus spinosa, P. fruticosa, Quercus pubescens and a rare continental element Prunus tenella (syn. Amygdalus nana). From the floristic point of view, the occurrence of a small population of a Pannonian endemic Artemisia pancicii is the most valuable. This putative glacial relict has a maximum of 20 localities across Pannonia, in Moravia, eastern Austria and in the Deliblatska peščara in northern Serbia. Adonis vernalis (Ranunculaceae) and Tropinota hirta (Cetoniidae) in Pouzdřany steppe. Kolby Forest on the plateau provides a nice example of Central European mesic oakhornbeam forest (Primulo veris-carpinetum betuli), though recently somewhat damaged by illegal logging. The closed canopy is dominated by Quercus petraea, Acer campestre and Carpinus betulus, with Ligustrum vulgare, Euonymus verrucosa or Crataegus laevigata in the shrub layer. The species-rich herb layer is characteristic by colourful spring aspect with Corydalis cava, C. solida, Anemone nemorosa, A. ranunculoides, Isopyrum thalictroides or 3 Viola mirabilis. Later on, Melica uniflora, Poa nemoralis, Convallaria majalis, Galium odoratum, Dactylis polygama and other nemoral species become dominant. On sunny forest edges, forest-steppe species are more abundant, including Quercus pubescens, Brachypodium pinnatum, Lithospermum purpurocaeruleum, Dictamnus albus, Euphorbia epithymoides, Peucedanum cervaria, Geranium sanguineum, Polygonatum odoratum, Carex michelii and Iris variegata.
