Velký a Malý Tisý National Nature Reserve

The Velký a Malý Tisý NNR was declared in June 1957 on a territory of 615 ha and ranks among the most important fishpond reserves in Bohemia. The reserve includes a complex of 14 fishponds, of which the largest is the Velký Tisý fishpond with a water surface of around 275 ha. The irregular banks of the Velký Tisý fishpond with many islands and peninsulas and the connection between the banks and the surrounding wet meadows and smaller water surfaces allowed the formation of exceptionally valuable wetland site with extensive littoral growths and numerous animal and plant species. Among the most significant protected plant species which occur in the reserve territory we can find: green-winged orchid (Orchis morio), water pygmyweed (Tillaea aquatica), tufted loosestrife (Naumburgia thyrsiflora), intermediate bladderwort (Utricularia intermedia), lousewort (Pedicularis sylvatica), adderstongue (Ophioglossum vulgatum), the marsh fern (Thelypteris palustris) and interrupted club-moss (Lycopodium annotinum). The most significant and most researched fauna of the Tisý fishponds is the birds. In addition to common birds species, the white-tailed eagle (Haliaeetus albicilla), marsh harrier (Circus aeruginosus), common tern (Sterna hirundo), blue throat (Luscinia svecica), water rail (Rallus aquaticus), little crake (Porzana parva), penduline tit (Remiz pendulinus), black kite (Milvus migras) and bearded tit (Panurus biarmicus) all nest in the NNR territory. The reedbeds and surrounding growths provide nesting sites for dozens of bird species whose existence depends on these biotopes.
