Natural monuments Moravian

Natural Monument Razovské Tuffs 2

Basic information

Natural Monument Razovské Tuffs is situated on the bank of Slezská Harta Damn. Local tuffs were created by volcanic activity of a nearby extinct volcano called Velký Roudný (the best preserved stratovolcano in Moravia). The site was declared a natural monument in the area of 10.44 ha in 1997.

Subject of protection

An abandoned tuff quarry is the subject of protection here. Since middle ages it has served as a supply for building material for historic buildings far and wide.

Living nature

Similarly to the area of Uhlířský vrch, calorific basic biotopes originated here owing to the mining and pyroclastic denundation. We can find thermophilous plant species here which do not grow anywhere else close by. Most of the thermophilous species is concentrated on the outcrops of tuffs and on the denundated places. The local population of Yellow Chamomile (Cota tinctoria) is more abundant in here than in Velký Roudný. Carthusian Pink (Dianthus carthusianorum) grows in great numbers here, too. Far from their natural territories the species of Fescue (Festuca rupicola) and (Melica transsilvanica) occur here. In order to preserve the denundated tuff outcrops and keep the population numbers of subthermophilous species, self-seeded woody species must be gradually reduced and some areas must be selectively scythed.
