Site description (2002 baseline):
Site location and context
The complex of four large ponds built in the 14th century (Nesyt - 320 ha, Hlohovecký - 104 ha, Prostøední - 48 ha, Mlýnský - 107 ha) is situated in a wide lowland part of southern Moravia between the towns of Sedlec u Mikulova and Lednice. The ponds are filled with water from the Vèelínk stream. The isolated Zámecký rybník pond (30 ha) in Lednice is filled from the Dyje river. The ponds are shallow and eutrophic with extensive reedbeds (they cover up to 50 ha of the total area). The Zámecký rybník pond is situated in a park with many old trees. In the pond there are also 15 islets with stands of oaks and other trees. Each of the other ponds, except for Nesyt, includes two small islets. The ponds are a part of theLednice-Valtice Cultural Landscape, which was listed as an UNESCO World Heritage Site in 1996.
The IBA is important for both breeding and passage waterbirds. The Nesyt Pond reedbeds hold the largest breeding population of
Panurus biarmicus in the Czech Republic (up to 100 pairs), and the islets of Zámecky rybník pond support the largest breeding colony nationally of
Nycticorax nycticorax. The parkland adjacent to the ponds supports a variety of breeding woodpeckers and passerines.
Pressure/threats to key biodiversity
The intensity of fish-farming practices has been lowered in accordance with a management plan adopted in 1995. Nevertheless these practices have, in conjunction with agricultural activities, caused nutrient pollution of the ponds.
More than 92% belong to the Lednické rybníky ponds National Nature Reserve and more than 93% belong to a Ramsar site. IBA is covered by SPA.
