Holý vrch u Hlinné, protected area in Czech Republic

Holý vrch u Hlinné is a nature reserve on the grassy Lysá hora hill between Hlinná and Kundratice, about seven kilometres from Litoměřice. Its northern and western slopes carry columnar basalt outcrops up to 10 metres high, surrounded by scree formed during periglacial weathering. The reserve covers 9.23 hectares at 484–578 metres above sea level.

The reserve was declared in 1949 to protect a hybrid of the two pasqueflowers growing here, Pulsatilla × hackelii. Before that, sheep and goats grazed the site for decades; when grazing stopped, Pulsatilla patens declined, so from the 1970s various management measures were tested. Sheep grazing was restored around 2000 to stabilize the population.

The reserve lies between Hlinná and Kundratice, about halfway along the road where the green-marked hiking trail crosses it; the 10 km Hlinná–Kamýk nature trail runs through the middle of the protected area and also leads to the Plešivec natural monument. Cycle route 3057 passes around the reserve. Spring and summer are the best months, when views open toward Radobýl hill and the Polabí lowland.

The reserve was declared in 1949 specifically because a natural hybrid of the two local pasqueflowers, Pulsatilla × hackelii, was growing here; about 25 of these hybrid plants still occur on the site. Sheep and goats grazed the slope for decades before protection, and grazing was reintroduced around 2000 to keep the pasqueflower population from declining.
