Svatojánský okruh
LIGHT WARM-REQUIRING OAK WOODS
Warm-requiring are one of the most significant biotopes of Český kras. They
occure at the peaks and upper places of the southern and south-western
orientated slopes, from the shallow to the middle deep, intermittent soils,
rendzinas. On the limestones occures an endemic vegetation of the oak and
Lathyrus pannonicus and on the acid rocks stunted oaks with Vincetoxicum
hirundinaria. This type of fellowship is an example of the contact between
forestery and steppic vegetation.
The dominate type of oaks is the Downey Oak. The shrub layer is mainly made by
European Cornel. In the herb layer grows Purple Gromwell, Dictamnus Albus,
Anthericum ramosum, Glaucous Bedstraw.
From the beetles lives here the protected stag beetle, whose occurence is the
reason for higher protection of this territory within the sites of European
importance Natura 2000
