Pastvisko u Lednice National Nature Monument

The Pastvisko u Lednice (Lednice Pastures) NNM covers an area of 30.5ha and consists of wetlands on the right-bank floodplains of the Dyje river by the road from Lednice to Podivín in the Jihomoravský kraj – South Moravian Region. The protected area was declared in 1990 to protect wetland ecosystems which are an important bird nesting site and also to protect many other rare animals which live here.
These wetlands have formed in a shallow and periodically flooded depression which is filled with fluvial sediments from the Dyje river. The terrain surface is covered with Gley soils and a fen covering has formed in places. The territory is influenced by man-made drainage and irrigation channels. Part of the territory lies on abandoned farmland. The natural herb and grass communities of a flooded fen are gradually returning to the protected area.
The wetland vegetation is dominated by growths of common reed (Phragmites australis), bulrushes (Typha sp.) and greater pond-sedge (Carex riparia). Significant plants which grow in shallow water include the water violet (Hottonia palustris) and wavy bladderwort (Utricularia australis). The open wetlands are fringed by intermittently flooded white willow (Salix alba) stands to the north-west, with summer snowflakes (Leucojum aestivum) in the undergrowth. The monument is also notable for the occurrence of rare algae, blue-green algae and fungi. The orange crep (Crepidotus crocophyllus) is a very rare fungus which can be found at the monument.
The shallow waters and wetlands also provide ideal conditions for molluscs such as the swan mussel (Anodonta cygnea), painter’s mussel (Unio pictorum) and the rare ramshorn snail (Anisus vorticulus). The fauna of wetland butterflies and of spiders display high species diversity and the rarest spiders include the blue web spider Argenna patula and the jumping spider Marpissa canestrinii. Numerous amphibian species in the protected area include the edible frog (Rana esculenta), agile frog (Rana dalmatina), moor frog (Rana arvalis), European tree-frog (Hyla arborea) and the fire-bellied toad (Bombina bombina). Mammals which live on the territory include red deer (Cervus elaphus) and the European beaver (Castor fiber).
The Lednice pasturelands are an important nesting site for many wetland and aquatic bird species such as greylag goose (Anser anser), gadwall (Anas strepera) and red-crested pochard (Netta rufina). Other notable birds which occur here are the water rail (Rallus aquaticus), penduline tit (Remiz pendulinus) and bearded tit (Panarus biarmicus), whereas others such as the bittern (Botaurus stellaris) stop over on their migrations or overwinter here. Fish-eating birds such as the white-tailed eagle (Haliaeetus albicilla), herons (Ardea sp.) and cormorants (Phalacrocorax carbo) fly into the area from their nesting sites on the surrounding fishponds.
