U Strejčkova lomu

U Strejčkova lomu is a small nature reserve in Moravia, tucked between the villages of Grygov and Krčmaň in the Olomouc district. Its name refers to a former limestone quarry, traces of which are still visible in the landscape, though most of the area today is covered by steppe grassland typical of warmth-loving habitats on Devonian limestone bedrock.

Why is this site protected?

The area was declared a nature monument in 1952 and was later also included in the European Natura 2000 network. It is managed by the Regional Authority of the Olomouc Region. The main purpose of protection is to preserve xerothermic grasslands and the invertebrates associated with them, which have found particularly favorable conditions on the limestone substrate.

What can visitors see here?

The reserve's flagship species is the greater pasque-flower (Pulsatilla grandis) — the site holds one of the largest populations of this plant in Moravia, with counts reaching up to 3,570 clumps recorded in 2000. Alongside the pasque-flower, other heat-loving plants grow here, including yellow flax, fringed gentian, and orchids such as the three-toothed variety. This rich plant cover supports numerous invertebrates, among them steppe butterfly species like burnet moths and chalkhill blues, for which these grasslands are among the few remaining habitats in the region.

What does the site look like today?

The former limestone quarry that gave the reserve its name has largely become overgrown with vegetation, though rock outcrops remain visible and add character to the landscape. Without regular management, the steppe grassland would quickly be overtaken by shrubs and trees, so the area is mown on a regular basis and encroaching woody growth is removed to keep the habitat open — a condition essential for the survival of its heat-loving species.

Who is this destination for?

U Strejčkova lomu appeals to nature lovers, amateur botanists, and anyone looking for a quiet walk away from crowds. Given its small size and the fragility of the habitat, visitors are encouraged to stick to marked paths and avoid stepping onto the grassland, especially during the pasque-flower blooming season when the vegetation is most vulnerable.

Frequently asked questions

When is the best time to visit U Strejčkova lomu? The most visually striking period is spring, when the greater pasque-flower blooms — typically around late March to early April, though the exact timing depends on the year's weather.

Is the site open to the public? Yes, as a nature monument the area can be visited on foot, though the usual restrictions for small protected areas apply — visitors should respect the vegetation and not pick any plants.

Where does the name come from? The name refers to a former limestone quarry that once operated at the site, reportedly owned or managed by a man named Strejček — hence "Strejček's quarry."

Are there other natural attractions nearby? Yes, the region between Grygov and Krčmaň in Central Haná is home to several similar small protected areas on limestone bedrock, making it an interesting destination for a longer nature-focused trip.
