Natural Monument Rohovec

The Natural Monument was declared in 1992. It is a rugged valley slope with spring areas and predominant spruce vegetation, which is the biotope of the endangered ant species Formica polyctena.

Animate nature

The site is dominated by an age-differentiated mixed forest with a prevalence of the Norway Spruce with the presence of individuals of the Silver Fir (Abies alba), Scots Pine (Pinus sylvestris), European Beech (Fagus sylvatica), and the European Weeping Birch (Betula pendula). The spring areas and wet ravines feature the Black Alder (Alnus glutinosa). The undergrowth is rich in the Deer Fern (Blechnum spicant), and the Willow Gentian (Gentiana asclepiadea) abounds in the lighter spots. Forest ants of the species Formica polyctena make up a very numerous population. The 1999 inventorying identified 158 ant hills over approximately 30 hectares. The largest ant hill has a diameter of three metres and is one metre tall. The density of the ant hills is positively affected by the considerate thinning of the spruce, which is why this type of management is promoted in the Natural Monument.
