These semi-dry grasslands of the Bílé Karpaty Mountains on the Czech-Slovak border are co-dominated by Brachypodium pinnatum, Bromus erectus, Carex montana and Molinia arundinacea. With 60–80 vascular plant species per 16–25 m² (and even more in places) it is the species-richest plant community of the Czech Republic. Stands are composed of species of meadows, dry grasslands, open forests and forest fringes, including species of intermittently wet soils. Soils are deep and heavy, developed on calcareous flysch sediments. These grasslands are replacing beech and hornbeam forests. Traditionally they have been mown for hay once a year, usually in summer, and occasionally grazed as well. After abandonment they decline due to rapid shrub encroachment. Therefore mowing has been introduced at several sites as a conservation measure.
