Black storks built a nest in a fork of thick oak branches. But they laid the foundation of the nest badly. In order for the nest not to fall, they would have to place strong sticks in the fork of the oak branches to maintain the weight of the nest. Unfortunately, this did not happen. The storks gradually lined the poorly laid nest with moss. As it rained, the moss sucked in water. The nest became incredibly heavy. The thin-stick base could not bear its weight any longer and almost the entire nest fell to the ground. After this incident, the storks left the site.

In 1964, the Balkan chamois (Rupicapra rupicapra balcanica) was reintroduced to the area of Biokovo, and he acclimatized there well. Chamois is a species protected by the Convention on the Conservation of European Wildlife and Natural Habitats (Berne Convention).

Lobaria pulmonaria is a large epiphytic lichen. It is bound to trees in a well-preserved natural forests, unaffected by air pollution. It is most often found on beeches (e.g. in the Biogradska Gora in Montenegro, where it is very common). It became extinct in the Czech Republic, except the Bohemian Forest and the Upper Palantine Forest. The following photographs show lobaria pulmonaria on the bark of old beeches in natural beech forests, hidden in karst sinkholes on the plateau of the Biokovo mountain range in Croatia.
