Svatojánský okruh


Present state of the forest of Český kras is a result of their intensive use starting in medieval, maybe some parts of prehistory. There was a stump farming, especially with hornbeams, but also with beeches. The result is the domination of hornbeams against oaks and these both types against beeches in this area. Hornbeam significantly affects light and humus conditions in the forest, this is reflected on the composition of undergrowth.
Because of that are calcareous beech rarer in Český kras. Herb layer isn’t that rich like in warm-requiring oak woods because of bad light conditions. Here are mezereons and some protected orchids like Red Helleborine or White Helleborine. In the dark we can see hunting insectivorous barbastelle.
In this biotope lives an ant beetle which eats some species of bark beetle and is an important regulator during the regulation of the wood-decaying insect.
Near the stop are two best preserved superficial karstic surfaces – sinkholes. They are situated in the depression above southern slope of the valley. It works as a container of the waters flowing from the surroundings and probably goes to the unknown cave systems.
