Information for visitors
Interesting facts Velký a Malý Tisý
The ponds have rugged shores
All ponds of the reserve have rugged shores with peninsulas, islets and coves. They are followed by fields, forests, heaths and waterlogged meadows. The shores used to be completely overgrown with wetland vegetation, such as reeds or cattails. Despite considerable protection of the area, in the last century there was an increase in fish farming and the decline of vegetation. Efforts are currently underway to reduce the number of fish deployed and restore these stands, but this will be a very long-term issue.
Thanks to the rugged shores of the ponds, many rare species of birds have found refuge here and one of the largest ornithological reserves in our country has been established here. The birds not only live here, but use the ponds as a stop during migration and also as a gathering place before regular departures. More than 100 species of birds nest in ponds, such as the sea eagle, the common tern, the little rattlesnake, the reed warbler, the gray heron and many other rare and protected species. A large number of beetles, amphibians and molluscs also live here.
Waterlogged forests and wetland flora
The original oak groves and alders were covered with water. Parts of the waterlogged forest have been preserved as willows and alders. Even former pastures are overgrown with birch and pine trees. The reed stand on the shores of ponds is mainly represented by the common reed, the marsh fern, the arrowroot, the marsh devil and many other plants. You can also meet the round-leaved sundew. There are dozens of species of rare plants.
