Abstrakt
The representativeness analysis was based on 2002–2003 questionnaire survey data characterising natural environments and forest habitat types, as well as dominant tree species present in 1141 nature reserves located on land administered by the State Forests. The comparison of these characteristics with those analogous to the areas in the Regional Directorates of the State Forests pointed out to an overrepresentation of areas with aquatic ecosystems (31 times), mires and peatbogs (6 times) followed by fertile humid and floodplain forest habitats, as well as nutrient-demanding broadleaved tree species associated with them, while dry coniferous (0.49) and fresh (0.31) forest habitats were found to be underrepresented. Montane alder car forests are not represented.
