Wetlands

 

Description: Podyjí NP is relatively poor in wetland biotopes. Only around 13 ponds can be found on the whole NP territory. In most cases the bankside vegetation around these ponds is severely restricted or completely missing. The vegetation in all of these ponds suffers from the excessive fish stocks. The Jejkal fishpond near Vranov nad Dyjí is one of the most notable localities, because valuable waterlogged meadows surround the pond. Small pools which are significant as amphibian breeding sites can be found at several localities in the forests. Unfortunately, the damp meadows, small streams and springs in the current buffer zone were the victims of extensive land drainage works carried out during the period of socialist collective agriculture. These areas are mostly arable farmland today and often suffer from intensive erosion.

Flora: Specially protected plants which flower on the fen meadows in the springtime include the broad-leaved marsh orchid (Dactylorhiza majalis), Siberian iris (Iris sibirica) and occasionally the globeflower (Trollius eurpaeus). The brown sedge (Carex disticha) grows here and the sward sedge (Carex cespitosa) forms its typical tussocks. We may even find the rare snow parsley Cnidium dubium or the highly endangered Allium angulosum of the onion family in waterlogged areas of the meadows. The ponds are the home to rigid hornwort (Ceratophyllum demersum), curled pondweed (Potamogeton crispus), and occasionally the wavy bladderwort (Utricularia australis). Typical growths of common reed (Phragmites australis), bulrush (Typha latifolia) and sedges (Carex spp.) can be found on the banks of the fishponds. The mosses in these wetlands include river feather-moss (Brachythecium rivulare), streamside leptodictyum moss (Leptodictyum riparium) and pointed spear-moss (Calliergmella cuspidate).

Fauna: The most typical inhabitants of the various kinds of wetlands, such as the forest and meadow pools, small ponds and the surrounding waterlogged meadows are the amphibians. As well as the common species such as the common toad (Bufo bufo) and the common tree frog (Hyla arborea), several unusual and rare species can be found here in Podyjí. A significant population of the Italian crested newt (Triturus carnifex) can be found here. The most interesting of the many groups of invertebrates is the fairy shrimp (Eubranchipus grubii) which has been found in a forest pool near Podmolí. Significant dragonfly species include the dainty blue damselfly (Coenagrion scitulum), scarlet dragonfly (Crocothemis erythraea) and the southern skimmer (Orthetrum brunneum). Unusual predatory diving beetles which mostly occur in the eastern part of the national park include Laccophilus variegatus and Bidessus nassutus.
