Biodiversity is a common term, which has not been, however, exactly defined yet. It is based partly on another term being used for much longer time, a diversity. To maintain biodiversity, species and/or whole communities have to be protected from extinction. The nature conservation agencies are focused frequently on the forests, which represent the largest climax ecosystem in the central Europe. There are, however, no virgin forests nowadays. The protected forest areas have been changed and/or reshaped due to long-term human intervention, which is an issue the nature conservationists have to cope with. The Catalogue adds more information to knowledge base of forest management in protected areas. Central-European forests of lower and middle altitudes have developed under thousand years lasting human interventions. This approach contributed to existence of thin stands allowing penetration of solar radiation through broken canopy. The wood was harvested according to particular needs using a selection cut. Contemporary Czech forestry has abandoned the old management practices. Therefore, full-canopy forest stands disabling long-term or permanent life of the species that benefitted from almost forgotten management systems are common nowadays. To maintain or restore the high level of biodiversity, the return to "the old-fashioned silvicultural measures" is needed. The Catalogue content is divided into eight silvicultural measures proposed to support biodiversity: (1) Leaving forest to spontaneous development (non-intervention management); (2) Conversion into selection forest (or at least no clear-cutting system); (3) Thinning to keep a broken forest canopy; (4) Coppice and coppice with standards systems; (5) Forest pasture; (6) Overaged trees and dead wood management; (7) Care of forest edges and (8) Intraspecies diversity care. The Catalogue is based on analyses of management plans of set of protected areas and available literature, too. The investigations of applied measures were established on demonstration objects (permanent research and monitoring plots) within the Czech Republic.
