To highlight the natural function of the forest, part of it was designated as a forest reserve.
Here, the natural processes can take place optimally. The forest reserve only contains native trees and shrubs.
There is a regeneration of species that can tolerate shade, such as beech trees, and open expanses of species that require more sunlight, such as birch, pine, and native oak. You can also find shrubs like mountain ash and alder buckthorn. Standing dead trees and lying dead wood can also be found in abundance. Thick, dead wood is particularly important for certain types of flora and fauna. Roughly 40% of the organisms that live in the forest rely on dead wood.
Different bird species, such as the marsh tit and the hawfinch, thrive in forests like these. They even serve as the determining factor for the value of the forest. We refer to them as key species.
