Slepeč

Slepeč is a small but ecologically significant nature monument on the right bank of the Jizera River, roughly 1.5 km west of Benátky nad Jizerou, straddling the cadastral areas of Benátky nad Jizerou and Kochánky. The protected site covers 7.75 hectares on a gently south-sloping plateau cut by several dry erosional ravines descending toward the river.

Why is this site protected?

The primary reason for protection is the presence of the critically endangered lady's slipper orchid (Cypripedium calceolus). The population found at Slepeč is currently the only known occurrence of this species in the Mladá Boleslav district, making the site a key conservation point in the wider Jizera region.

What is the history of the site's protection?

Efforts to protect the area date back to 1970, when it first received approval from local councils. Formal status as a protected natural phenomenon was granted by district council decree on 17 April 1984, and the protection was confirmed and refined through a district office regulation in 1998.

What does the underlying geology look like?

The bedrock consists of middle Turonian marls and marlstones, largely covered by Pleistocene loess. Former quarries in the southern part of the site preserve marine fossils from the Cretaceous period, evidence that this area was once the floor of a shallow sea.

What vegetation grows here?

The reserve is covered by hornbeam-oak forests and thermophilic oak stands with a relatively well-preserved herb layer, although part of the territory is unfortunately dominated by spruce monocultures and other conifer species unsuited to this habitat. Botanical surveys have recorded 175 species of vascular plants, including several orchid species and indicator plants typical of oak and beech woodlands.

What animal species live in the area?

The fauna of Slepeč is surprisingly rich for such a small territory. Surveys have documented 28 spider species, 22 bird species, and rare ground beetles from the Carabidae family. Among the birds, notable threatened species include the spotted flycatcher and the middle spotted woodpecker, for which the preserved old-growth trees provide important breeding habitat.
