The NNR territory covers the Stolová hora – also known as Tabulová hora – ‘Table Mountain’ (458.8 m) klippen in the Pavlovské vrchy hills to the west of the village of Klentnice. The main part of the NNR was declared in 1951 and the neighbouring Růžový vrch Nature Reserve and Kočičí kámen Nature Monument, which lie to the south of Stolová hora, were joined to the NNR territory in 2000. The reserve currently covers an area of 109.06 ha and lies in the parishes of Bavory, Perná and Klentnice, in the the Pálava PLA and in the Jihomoravský kraj – South Moravian Region, at elevations between 293 and 459 metres. The subject of the protection are rock communities and dry grasslands on a limestone basement with rich thermophilous flora and fauna.
The distinctive geomorphological form of the table mountain with a flat summit is considered to be a remnant of a denudation surface of Pliocene age and is formed of Ernstbrunn limestone. There are various, notable rock formations. The Klentnice strata are exposed on the northern slopes and the slopes are covered with clayey-stoney sediments from the last glacial period with loess in places.
The flora of the reserve numbers 552 vascular plant species and subspecies, which were documented here between 1991 and 2005, of which 42 are protected species. The southern edge of the summit plateau of Stolová hora is probably the only locality in the Czech Republic where the African sage (Salvia aethiopis) grows naturally. The dandelion Taraxacum serotinum grows on the dry meadow on the southern slopes and has been collected here since the mid 19th century but the current population only numbers about 10 plants. Among the specially protected plant species here we can also mention the wild garlic Allium angulosum, Cornelian cherry (Cornus mas), downy or white oak (Quercus pubescens), purple mullein (Verbascum phoeniceum), the crucifer Biscutella laevigata subsp. varia, spring pheasant´s eye (Adonis vernalis), the aster - Aster amellus, goldilocks aster (Aster linosyris), Lumnitzer´s pink (Dianthus lumnitzeri), the squarrose knapweed (Cyanus triumfettii subsp. axillaris), the feathergrasses Stipa pennata and Stipa pulcherrima, great pasque flower (Pulsatilla grandis), the dwarf iris Iris pumila, the rock sand iris (Iris humilis subsp. arenaria), the globe daisy Globularia bisnagarica, the milkvetches Astragalus austriacus and A. onobrychis, narrow-leaved flax (Linum tenuifolium), martagon lily (Lilium martagon), rue-leaved saxifrage (Saxifraga tridactylites), livelong saxifrage (Saxifraga paniculata), wolfsbane (Aconitum vulparia subsp. vulparia), white helleborine (Cephalanthera damasonium), mountain germander (Teucrium montanum), the clematis - Clematis recta, the buttercup Ranunculus illyricus, the mouse-ear Cerastium tenoreanum, snowdrop windflower (Anemone sylvestris), the knapweed Jurinea mollis, snowdrop (Galanthus nivalis), field fleawort (Tephroseris integrifolia), basket of gold (Aurinia saxatilis subsp. arduini), burning bush (Dictamnus albus), night-scented stock (Hesperis tristis), the violet Viola ambigua, military orchid (Orchis militaris), the bell flowers Campanula bononiensis and C. sibirica and the meadow-rue (Thalictrum foetidum).
The rare mammoth wasp Scolia hirta is quite often seen on the steppe localities sitting on the flowers and the field cricket (Gryllus campestris) lives here in large numbers, as does the owlfly Libelloides macaronius. Our largest and most beautiful chafer beetle – the rose chafer (Cetonischema aeruginosa) can be seen here. Skylarks(Alauda arvensis) nest on the flat hilltop and corn buntings (Miliaria calandra) and stonechats (Saxicola torquata) sit on the tops of bushes to sing their songs. The colony of European souslik (Spermophilus citellus) on the edge of the football pitch in Klentnice died out for unknown reasons. The common hamster (Cricetus cricetus) lives at the foot of Stolová hora. A small colony of lesser horseshoe bats (Rhinolphus hipposideros) regularly hibernates in the large rock fissure in the western wall.
The majority of the forest growths where artificially renewed in the past and partly with unsuitable tree species for the locality. The growths are classified as special purpose forest and part are also registered as protection forests. It is necessary to remove the black locust trees (Robinia pseudocacia), tree of heaven (Ailanthus altissima) and Austrian pine (Pinus nigra) – the only one of the three which does not rejuvenate naturally here – from the reserve’s forests and replace them with autochthonous tree species.
The Stolová hora was already partially deforested by the Early Bronze Age. Limestone quarrying began in the area in medieval times and several small abandoned quarries can be seen on the NNR territory. Grazing was practised on the territory until the 1950s and the summit of the table mountain was cut for hay once a year. Grazing has been reintroduced on the territory as beneficial methods of managing the steppe grasslands.
A fortified settlement existed on the summit in the Late Bronze Age.
The Sirotčí hrádek ruined castle is located on two steep rock cliffs on the summit of Růžový vrch. This castle was originally a gothic border castle which was first mentioned in the 13th century but was destroyed by the invading Swedes in 1645 and has been abandoned ever since.
