Zbrašov aragonite caves and brown rankers. The surface of the protected area is mostly forest canopy cover, which has a near-natural tree composition. There is growing mixed forest consisting of winter oak ("Quercus petraea"), beech ("Fagus sylvatica"), common hornbeam ("Carpinus betulus"), sycamore ("Acer pseudoplatanus"), spruce ash ("Fraxinus excelsio"), maple ("Acer platanoides"), small-leaved lime ("Tilia cordata"), sometimes Norway spruce ("Picea abies") and silver fir ("Abies alba"). Occasionally there are a few mountain elms ("Ulmus glabra"). In the past, these forests were negatively affected by forest management, such as logging and the subsequent planting in favor of spruce trees. In the future, these negative effects
Fagus sylvatica depends on the location: in forest areas, "F. sylvatica" grows to over , with branches being high up on the trunk. In open locations, it will become much shorter (typically ) and more massive. The leaves are alternate, simple, and entire or with a slightly crenate margin, 5–10 cm long and 3–7 cm broad, with 6–7 veins on each side of the leaf (7–10 veins in "Fagus orientalis"). When crenate, there is one point at each vein tip, never any points between the veins. The buds are long and slender, long and thick, but thicker (to ) where the buds
