A transfer of the concept of biodiversity in silvicultural practice may be efficient, provided forest management planning is taken into account by. This paper is concerned with intricacies of the concept of biodiversity and the need for specialists to be involved in the planning process. It presents a critical view of some interpretations of biodiversity. Instead of a tendency towards maximisation of biodiversity, it presents a trend towards potential natural biodiversity, whereby the importance of forest reserves is pointed out. The conservation of biodiversity is feasible within the framework of a close-to-nature approach in the total forest area; a strategy aimed at dividing ecosystems into protective and productive systems cannot prevent the process of extinction of species in the long run.
