Lom Na plachtě, Natural monument in Třebohostice, Czech Republic.

Lom Na plachtě is a natural monument of 0.7918 ha in Třebohostice u Škvorec, with a protective zone of 0.6587 ha along its western edge. The abandoned granite quarry has rocky ground and temporary pools that form with the weather; water remains year-round in the northern part. A ring of trees and shrubs separates it from surrounding fields.

Stone extraction took place at this location until the mid-1960s, when the quarry was abandoned and left to nature. Over the following decades, natural recovery processes gradually transformed the former working site into an important ecological area.

The regional authorities of Central Bohemia established protection measures in 1990 to preserve this wetland habitat for amphibians and reptiles.

The site is accessible via walking paths that lead through different sections of the monument. Be prepared for muddy or wet conditions, especially during or after rainfall, as this enhances the pond formation process.

The strongly endangered fire-bellied toad (Bombina bombina) was the reason the quarry was added to the European list of sites of Community importance in 2005. Protecting it also shields the other amphibians and reptiles of the ponds, which makes it an umbrella species here.
