The northern steep slopes are covered with beech forest, which is a source of wood and home to all kinds of animals, ranging from long-horned beetles to bears.
During the day, the forest is filled with the drumming sounds of black, green and red-spotted woodpeckers, and from rowan tops echo the harsh screams of spotted nutcrackers and sonorous cuckoo songs. Meanwhile, Eurasian hobbies chase finches and tits between tree trunks, common buzzard circles above the grass slope and two ravens bustle by the mountain ridge. This bird bustle lasts until nightfall when Eurasian eagle and brown owl are awakened from their slumber.
Meadows, flown over by clouded apollos, scarce fritillaries and brown argus, and dug under by moles during the day, are visited by does and rabbits when the morning is still dark, and afterwards even a fox sneaks up behind.
This animal kingdom is no less vivid at night, when it's time for dormice, hazel dormice, martens and bats to wake up in tree crowns and go hunting for countless moths. Forest ground is enlivened by insects. Millipedes and arachnids, which spent the day hiding from the sun, are now facing a new threat – hungry mouths of toads, shrewmice and hedgehogs.
