Chrašická stráň

Chrašická stráň is a small but botanically significant nature reserve in the Chrudim district of the Pardubice Region in eastern Czechia, located near the village of Chrast. The protected area covers a steep, southwest-facing chalk slope rising above the Žejbro stream. Legal protection was established on 30 October 2002, with the aim of preserving a valuable geological formation together with natural plant communities typical of semi-dry, thermophilous grasslands and, in places, warmth-loving shrub vegetation.

What makes this slope so special?

The character of Chrašická stráň is shaped above all by its underlying geology and terrain. The slope's inclination and southwest orientation create exceptionally intense sun exposure, producing conditions favourable to vegetation typical of dry, warm habitats. The chalky substrate further enriches the soil with minerals favoured by many species of xerothermic grassland — plant communities that are increasingly rare across the wider Pardubice region.

Which plants can be found here?

The reserve is best known for its abundant population of branched St. Bernard's lily (Anthericum ramosum), one of the largest populations of the species recorded in the region. From a conservation standpoint, the presence of the European Michaelmas daisy (Aster amellus) is equally significant, with a relatively rich and well-preserved population growing on the slope.

Beyond these two flagship species, botanical surveys of Chrašická stráň have documented a range of other protected and threatened plants, including annual woundwort, pigeon scabious, yellow broomrape, sickle-leaved hare's ear, hedge woundwort, crested hair-grass, corymbed tansy, glaucous bedstraw, large-flowered rock-rose, large speedwell, mountain sedge, dwarf thistle, fringed gentian, bloody crane's-bill, willow-leaved fleabane, night-flowering catchfly, and field elm. Such species diversity within a relatively small area reflects the exceptional quality of this habitat.

The dominant vegetation type in the reserve is broad-leaved dry grassland belonging to the Bromion erecti alliance, classified within the Scabioso ochroleucae–Brachypodietum pinnati association — a plant community characteristic of warm, dry slopes across Czechia.

What else does this reserve protect?

In addition to its flora, Chrašická stráň was established to safeguard habitat for thermophilous insect species, as well as protected birds and other vertebrates that rely on the slope. Dry, sun-exposed xerothermic grasslands are a habitat type that has been steadily disappearing across much of Central Europe due to shrub encroachment and changing agricultural practices, which gives enclaves such as this one an importance that extends well beyond the local scale.

The protected area covers 1.7381 hectares, making it a small but intensively managed reserve. It is administered by the Regional Authority of the Pardubice Region. Botanical research has historically recorded 185 taxa of vascular plants at the site, while more recent surveys documented 169 taxa — a modest decline that botanists attribute to changes in land management and ongoing vegetation succession.
