Bělečský písník, Protected natural monument at a former sand pit in Běleč nad Orlicí, Czech Republic

Bělečský písník is a former sand pit on the western edge of Běleč nad Orlicí, about three kilometres east of Hradec Králové. The 3.92-hectare site, fenced and privately owned, has a water surface on its wet bottom and sandy edges where peatland plants grow.

Sand was excavated here from river deposits of the Orlice, and the pit was declared a natural monument on 23 August 1983, covering 3.92 hectares. Mining had ceased by then, and the flooded pit floor developed peat communities. The site is managed by the Regional Office of the Hradec Králové Region.

The name Bělečský písník comes from the village of Běleč nad Orlicí and the Czech word písník, meaning sand pit. The site is a former sand quarry, not an active one, and it has been a protected natural monument since 1983. The wet bottom of the pit now supports peatland communities, including round-leaved sundew and bog clubmoss.

The entire site is fenced and closed to the public, so it cannot be visited; the water is not open for swimming. The protected area lies on the western edge of Běleč nad Orlicí, about three kilometres east of Hradec Králové and three kilometres west of Třebechovice pod Orebem.

The site is a former sand pit where peatland formed on the wet excavated bottom, now holding protected and endangered plants. Two fungi were first collected in eastern Bohemia here: Lactarius scoticus and Russula clavipes.
