The article discusses the importance of preserving biodiversity in forests and developing sustainable management practices. It suggests that different forestry practices can help achieve these goals, such as protecting natural forests and managing production forests with nature-oriented principles. Research on stand-level biodiversity is crucial for developing guidelines, with a focus on indicators like stand structure and dynamic processes. At the landscape level, there is a need for efficient forest inventory methods and monitoring of the entire ecosystem. This includes assessing protection areas, forest stand characteristics, and other key biotopes. The study emphasizes the importance of defining terms and harmonizing classifications to improve forest management practices.
