Nature reserve Moravian

Hvozdnice Nature Reserve 1

Basic information

The site consists of meandering watercourse which here and there reveals bedrock. Local lake, peat bog and alluvial forest communities rich in species provide refuge to many bird and amphibian species. The site was declared a nature reserve in the area of 56.24 ha in 1989.

Subject of protection

The subject of protection comprises marsh ecosystems including Slavkov pond system in the alluvial plain of Hvozdnice creek and Hvozdnice meanders together with the outcrops of seat rocks and Pleistocene sediments. Fossilized remains of invertebrates (in particular the shells of cephalopods and pelecypod) as well as Lower Carboniferous plant species can be found in the silty clay. Bedrock can be seen at some parts of the stream bed. Aqueous glacial sediments – deposits of glacial streams and lakes – are part of the former sand pit which is situated in the reserve.

Flora

The vegetation consists of diverse plant communities of stagnant pond waters with natural littoral zone and connected sedged marshes and swamps and remaining alluvial forests. Water plants grow in the pond waters, e.g. Greater Duckweed (Spirodella polyrhiza), Water Buttercup (Batrachium aquatile), Shining Pondweed (Potamogeton lucens) and Utricularia australis. The following species grow in the litoral zone of the ponds and in mannagrassed sedged marshes: Yellow Flag Iris (Iris pseudacorus), a poisonous umbelliferous plant with white flowers Fineleaf waterdropwort (Oenanthe aquatica) and Hawaii Arrowhead (Sagittaria sagittifolia) which is commonly called a “snake tongue” due to the shape of its leaves.
