| Popis | Wetlands are among the most endangered ecosystems in Central Europe. Therefore, large number of wetland organisms are endangered at the same time. Frequency of 94 red-list species were evaluated in the studied area of the south-eastern part of the Bohemian-Moravian Highlands. Historical data were taken from literature, botanical surveys, and databases. Recent occurrences are the result of the own field survey. Almost half of the evaluated species are recently considered as disappeared, or extinct in the area. Carex lasiocarpa and Pedicularis palustris are plants of high conservancy importance and at the same time belongs to recently missing species, with high probability of extinction, in the studied region. Drosera rotundifolia survives only at one locality. Prevailing decreasing number of species localities is associated mainly with the loss of suitable low-productive aquatic and wetland habitats. The study points to the continuing negative trend of reducing the occurrence of most of the evaluated endangered species and the related degradation of natural habitats in the selected area. |
